Jin-Yi Yu: Andy
Andy Dinh: Hello.
Jin-Yi Yu: Andy You don't need
Jin-Yi Yu: When they need a way for me to meet you personally come away.
Jin-Yi Yu: It will first day you know I'm just trying to figure out whether or not I set up the meeting correctly because some sun, moon still than it was in the waiting room first. So you already coming as soon as I come to the meeting. I talked in
Andy Dinh: A waiting room.
Jin-Yi Yu: You all you didn't
Andy Dinh: I just launched it and then it just says waiting
Andy Dinh: To start, and then. Yeah.
Jin-Yi Yu: I would say more. OK, I see, I see. Okay, so you are you are before I started meeting. That's funny.
Jin-Yi Yu: Lucas. Lucas.
Lucas: Hello.
Jin-Yi Yu: Remember, everybody's face to the name
Jin-Yi Yu: Jimmy for your chemistry department.
Jennifer Campos Ayala: Yes, I am. Okay.
Are you
YU ZHAO: Hi.
Jin-Yi Yu: Deceive anyone, it is still coming
Jin-Yi Yu: Does anyone know how I can make anyone come to this meeting automatically get get into the meeting without waiting for my permission.
Jin-Yi Yu: And LinkedIn or Twitter.
Lucas: We didn't need a admission to get it.
Jin-Yi Yu: You didn't know. I think most of you.
Jin-Yi Yu: Did wait in the waiting room and I click on the meat.
Jin-Yi Yu: So I was afraid someone come in during the lecture and and i didn't pay attention to it a moment that person going to stay there and also some of you, doesn't seem to me. My automation company when anyway. I'm going to start it.
Jin-Yi Yu: Up here, this admission seems
Jin-Yi Yu: OK. So first we'll come to us as 200 copper physical cosmetology and then this is the first time teaching this class I'm nine so I used to use quite a lot. And Paul. Paul was was just use the site information and most of my
Jin-Yi Yu: Lecturing was based on my whiteboard discussion, but I'm gonna I'm gonna try to do that on on the
Jin-Yi Yu: On a room, using a wife, or using pen on the PowerPoint. So this will be my first had to teach a class on nine so bear with me if we can host it will slowly.
Jin-Yi Yu: So first I want to go to the PowerPoint and to give you a basic idea power this class, and then we'll take our
Jin-Yi Yu: First lecture here. Okay, now let me share screen.
And called
Jin-Yi Yu: Introduction and I need to switch to the table template.
Jin-Yi Yu: Okay, so our first album to give you a basic idea what to expect in this class. So of course I already sent you the syllabus.
Jin-Yi Yu: And naturally, as I said, Not see you in a sequence. I made a few changes based on the request for our university or also add in the office hour
Jin-Yi Yu: Because in the past. I don't do office hour so anyone just passing by Mel office and drop him off his class me any question. As long as I'm in my office and now since we are in a room, so I'll have to put the office, our happiness. A per year price here.
Jin-Yi Yu: Of his eyes here.
Jin-Yi Yu: Is Tuesday 132 to 30 so we have class on Tuesday until 1220 so I'm the same app to open one hour at a room this room location and we can have
Jin-Yi Yu: It is room location, we can have the office on can ask me question. And the reason I put in that particular time is because our try to give a Gusher of homework do
Jin-Yi Yu: Every Thursday. So on Tuesday, you can ask me question before you turn in your homework on Thursday.
Jin-Yi Yu: So that's the newest thing. I put in the syllabus. So you need to check the updates in a person on the my home, my website also on a canvas.
Jin-Yi Yu: So, and then the electrical costs. Everybody know that
Jin-Yi Yu: In the textbook is going to be three.
Jin-Yi Yu: Textbook and everything is going to be based on this textbook global physical cosmetology by Dennis Rodman my PhD advisor.
Jin-Yi Yu: And so I'm going to go through their actual chapter based on the chapter in this textbook, but this textbook actually is quite an event.
Jin-Yi Yu: If you do not have any background in meteorology in atmospheric or science or in the physical ocean. You may find it a little bit.
Jin-Yi Yu: Difficult to completely understand every sentence in this expo. However, this is a very, very contextual
Jin-Yi Yu: If you are going to be a PhD student in the fiscal karma area or you have background in physical Crimea area, then use definitely to re is Expo very carefully. If you don't understand anything then you try to figure out something I'll try to understand what
Jin-Yi Yu: Are the chapter, try to say because in Co. Most of the most important and ongoing research sector.
Jin-Yi Yu: And for those of you who are not going to walk on fiscal climate, but do not have enough training in this area, this textbook, give you a give you a set of vocabulary. So you know that what are these
Jin-Yi Yu: main subject men who are the people use for study kami kami change. So it's still good for you to resort and if you do not fully understand what he's talking about in this textbook.
Jin-Yi Yu: Priests, really, the second astronaut textbook, which is the Earth System Administrator covenant textbook later.
Jin-Yi Yu: And this us assistant principal is very, very good. And he was designed for more general public, so it can be a very good idea in discussion about our physical climate system.
Jin-Yi Yu: And actually, more than just physical calm, including me about your chemistry area and I find this book, very, very useful and use a very easy to understand language. So please
Jin-Yi Yu: Also read this textbook and assert Expo. You don't need to really a mass you really wanted, because the difficulty level of complexity level of risk textbook is in between this one.
Jin-Yi Yu: Is in this is Coco physical can County and this is the hostess leases introductory label and this is more events at events table.
Jin-Yi Yu: And this one is in between. Okay. And the reason I still mentioned this textbook.
Jin-Yi Yu: Is because if you are interested in any particular subject that is not fully address type the URL system, but was mentioning
Jin-Yi Yu: In the global fiscal committee College, then you should call release meteorology. Today it give a very detailed description of a lot of subjects issued on reading that was mentioning in these two textbook.
Jin-Yi Yu: And therefore acquainting will be every week we have a homework 70% and then we have a minimum 35% final study represent and university is one
Jin-Yi Yu: Or instructor Terry asked to the US shoe. Try to take care Amy assignment in the early part of the quarter as much as possible because if for any reason, in the worst scenario.
Jin-Yi Yu: Coffee and pandemic becomes getting so was when you actually have to shut down and you cannot attend a class or they cannot take the final then university or instructor may be
Jin-Yi Yu: Able to use the grading farming early part of the quarter to get a final grade in the Austin area. So, but in in
Jin-Yi Yu: In
Jin-Yi Yu: Your everything goes smoothly, then you will have 70% migrating from homework and then
Jin-Yi Yu: The other 75% from midterm. So you represent our final in a resource to give you homework by email. But since we're not doing the room. So when you plan your next Thursday.
Jin-Yi Yu: So our app to make a request. So whenever you turn in your when you turn in your homework, please send me the PDF. PDF and try to write your homework answer.
Jin-Yi Yu: By typing awarding sometimes I cannot read the handwriting from some of the student at MIT migrating very difficult. So our apt to have everybody turn in homework in PDF and also in the typing way.
Jin-Yi Yu: Now you know in handwriting. So if you have any questions please feel free to interrupt me
Jin-Yi Yu: So now this is a three textbook. I just mentioned here, here, here, and definitely you should try to get this textbook and because some obviously nice PRINT IF number in detail you can understand. You cannot fully understand my accent, then you should try to reorder writing in this textbook.
Jin-Yi Yu: I have a question. Is he has priests.
Nicholas Pham: For your office hours. Is it possible, and you could move them like a little bit later than 230 or
Nicholas Pham: Would you have
Nicholas Pham: Appointments as well.
Jin-Yi Yu: He's in a class.
Nicholas Pham: Yeah, I have a class at that time.
Jin-Yi Yu: What is it about your chemistry class. Okay.
Nicholas Pham: It's, it's actually from a different department from eh s
Nicholas Pham: Wanted to 20 that's why
Jin-Yi Yu: I know most of you as a student either take the biology or chemistry cycle right
Jin-Yi Yu: Anyone not apples and
Jin-Yi Yu: Oranges john
Jin-Yi Yu: Podesta Monday. OK. OK. So that's okay no evil, for example, who was not a speaking. Sorry, could you
Jin-Yi Yu: Nicholas Nicholas. Okay, I'm trying to remember the parish.
Jin-Yi Yu: I want to link them to face. Now I need to encourage them to put a voice because yes because if you cannot come it is like your office, I just send me a room Room meeting link and then
Jin-Yi Yu: Our schedule individual meeting with anybody who I'm to meet with me with me outside his office are just send me your email, and then we can meet on room. Yeah, no problem.
Jin-Yi Yu: So that's my professor
Nicholas Pham: Hsu. Thank you.
Jin-Yi Yu: That was I usually don't have over so you can just drop my mouth is.
Jin-Yi Yu: For now, cannot do that.
Jin-Yi Yu: This quarter. So I want to mention that
Jin-Yi Yu: I only caught off some of the chapter in this textbook and inside each chapter. I do not cover everything in the in the chapter. So you for the homework for the final meeting, I only cost you.
Jin-Yi Yu: The material I included in the lecture, anything that's not mentioned in my lecture and you will not show the textbook. I will test you on those questions in the final meeting.
Jin-Yi Yu: Okay, so basically we have a good idea. This is
Jin-Yi Yu: Called costs for years. I still then some other student from the art department. So the basic
Jin-Yi Yu: Characteristic of this class or student is cause is you are asked protect this cause, and some of you may not even need to work on fiscal cramming
Jin-Yi Yu: But a department. Think you should know fiscal Kermit aspect of the system. Right. So when I
Jin-Yi Yu: Design is class. I do not want to go to very, very detailed technical detail mathematical detail of this class. So basically, what I want you to
Jin-Yi Yu: Remember after this class is a whole picture of what is a system look like how air go up and down in a Thomas the hot water more east west or clockwise or counterclockwise in the ocean.
Jin-Yi Yu: And then why they do this way. Right. So that's the knowledge. So everything we need. We need to receive for for research. First is knowledge.
Jin-Yi Yu: Right you know this earth is this has the north pole, south pole colder in a pole warmer in the equator as knowledge. Right.
Jin-Yi Yu: Second part is the physical mechanism. The reason behind as a fiscal concept why nature. Want to do is
Jin-Yi Yu: Why we want to have a go up in equatorial region go Tom in a polar region by nature on the Torah.
Jin-Yi Yu: So there must be a physical reason to push a co op can equator and push the air, call me the polar region. So there's a fiscal opera.
Jin-Yi Yu: And NHL on the duties must be in order to accomplish something right because equator too much helium.
Jin-Yi Yu: Too much sunlight polarizes to call does not have enough sunlight. So if we do not have air to move around. We're going to get a shopaholic equator.
Jin-Yi Yu: And super Cole Porter region nature does not want to have extremely simple happen whenever something extreme happened nature will adjust itself right produce something to smooth out this extreme event.
Jin-Yi Yu: And that's something that nature produce is called when is called whether it's called karma is called secularization so many to produce all this occasion.
Jin-Yi Yu: Due to a reason and to come accomplish the call. Okay, that's what the second part of receiving if you need to know for doing research in this area, physical cancer.
Jin-Yi Yu: In order to quantitatively understand all this fiscal console to ask me based on this fiscal me how strong wind can be or how cold water how warm waters up
Jin-Yi Yu: We need to have a must muddy equation to describe this fiscal relationship. So we are able to do the calculation to quantitatively saying that if we fit into what
Jin-Yi Yu: Per meter squared of heating do to increase carbon dioxide concentration. How much woman, ours is going to be right. So we need to a mathematical
Jin-Yi Yu: Equation. So that's the reason we need oh encounter when we do research in this area knowledge fiscal concept and mass market knowledge is the most easy
Jin-Yi Yu: The easiest part of our toolkit. So I'm gonna go swimming whenever there's a number, whenever there is a equation I believe everybody in this fear. Sure. Remember our explicitly tell you
Jin-Yi Yu: And you should remember those number because now this number fill up your concept of what is our system side. So for example, when we say
Jin-Yi Yu: How does the system size look like right and then if I wanted to draw a picture to describe the systems that are not associated inside the system right then, how do you throw this system and then you're saying we can have our ocean right and this ocean is about his tape.
Jin-Yi Yu: And how the visit is about four kilometer.
Jin-Yi Yu: Lawson HOST YOU'RE IN HERE IN A pattern respond for kilometer and marriage. And then we have a commerce fear on the top, and I must fear is about 103 two
Jin-Yi Yu: 150 kilometer, so it is you have this idea right and their user inside is an omen spear we most of the climate scientists only study which part. The first 10 kilometer, right, because that's how troposphere.
Jin-Yi Yu: And that's where most
Jin-Yi Yu: Hello, sadness, where most of our
Jin-Yi Yu: Weather
Jin-Yi Yu: And climate is going to be studying. So the first 10 kilometer. If you study at the master chemistry, then you may go up to from surface.
Jin-Yi Yu: To about 50 kilometer. Why, because a lot of chemistry process transport is happening in the stratosphere, for example, own
Jin-Yi Yu: So you need to focus on this right and then how the this current system became to walk became the tribe emotion and then we know that you require. Anybody know how to turn on this, this
Jin-Yi Yu: Premise system.
Jin-Yi Yu: Well Konami's produce motion.
Jin-Yi Yu: Why we have motion, you know, climate system. The reason is because we have bought. We have some night.
Jin-Yi Yu: So our current system is a solar power machine, right. So these cars, trying to tell you inside this machine. Where is the how does. If we go to have to change the direction of emotion or what we're calling our this way. And when energy comes in. How does this machine utilize all this energy
Jin-Yi Yu: Knowledge, I'm going to tell you. And then I'm going to discard a fiscal mechanism behind
Jin-Yi Yu: Now, should be this one.
Jin-Yi Yu: So the, the basic comes this thing, this class, which I will tell you, knowledge Park.
Jin-Yi Yu: Now,
Jin-Yi Yu: Second is a physical cancer.
Jin-Yi Yu: Cell is a mathematical equation.
Jin-Yi Yu: Formula.
Jin-Yi Yu: Control is physical process. And actually I'm going only asked you to remember probably only one or two, right. So this is not my main focus the main focus is here knowledge.
Jin-Yi Yu: And the physical comes up. So all my explanation will be basically on this is what comes up. So basically these cards will appeal a physical understanding about us any system. Right. So what is the physical
Jin-Yi Yu: Issue. Now we need to understand. First we need to know how our current system looked at, right. Like, I must be ocean, then Christ Sophia right
Jin-Yi Yu: And then we need to turn on the sunlight to power our common system. And when the center reach the earth.
Jin-Yi Yu: How does us take care of these how those are kind of system. Take care of his son. Anybody know we have atmosphere ocean. And then in our climate system run, who is the one absolve or receive all this energy some sent us some solar radiation anybody
Jin-Yi Yu: thermosphere
Jin-Yi Yu: Ocean land.
Jin-Yi Yu: Mines already
Jin-Yi Yu: Then an ocean. That's correct. Right.
Jin-Yi Yu: So look.
Jin-Yi Yu: It's a source of pride.
Jin-Yi Yu: When a son, I come to our atmosphere come to a common system, who is which component Academy sister Sunday income, therefore it must be right, but it must be cannot do anything to center.
Jin-Yi Yu: So mostly if you have a very thick atmosphere or thing that I must be because in all those kind of system, our commerce is basically transparent to Santa.
Jin-Yi Yu: So all the solar energy coconut all of our climate system and open a door can receive a delivery from the sun. We have a package of
Jin-Yi Yu: Or energy is the ocean and then service so surprised why other must be cannot do anything about it, right. So that's comes up, you need to understand right so that's the
Jin-Yi Yu: Energy. That's the second part after we know our, how come system system look like and then we turn on a Sunday we need to know how does energy can receive and then redistributed.
Jin-Yi Yu: Inside atmosphere ocean. And then that because that's going to affect how our temperature look back from the ocean to the atmosphere and there. So this is the path we decide from energy. He then to temperature. I thought we have temperature
Jin-Yi Yu: Our ministry still motionless scam. Nothing happened. But we, how does the wind, comma, how do we, why do we have em circulation when because temperature is going to offend anybody
Jin-Yi Yu: Temperature is perfect sense to have air.
Jin-Yi Yu: Base to aliens go to decide how heavy or how the is when some powers has a heavier have a must be some paddle Earth has a
Jin-Yi Yu: Lighter have a must be about when we say we have high pressure, no pressure when the pressure is not uniform. So on Earth's surface. Then you put this pressure difference when we have pressure difference is copy other P when we are pressure difference
Jin-Yi Yu: Then this pressure defense is going to try motion.
Jin-Yi Yu: So just go to parties when
Jin-Yi Yu: And when is going to come back to back. Move the temperature around in order to panelists, anything that anybody produced by Sunday because some I
Jin-Yi Yu: Send a lot of sun Sentinel sunlight to equator and only a little to the polar region. So nature trying to do something.
Jin-Yi Yu: So if you are the coffee machine. How did you move additional a sexy among those key from equator to pop
Jin-Yi Yu: Then you say, Okay, I'm going to warm up temperature play some solar energy and his temperature is going to change the density of air atmospheric air with the different density is going to produce
Jin-Yi Yu: Different pressure over equator and over polar region equally is very, very warm, it can vary by line.
Jin-Yi Yu: You have like a year in a porridge is very, very cool. So you have heavy in here so become high pressure year and equator become a low pressure. So which direction we should go.
Jin-Yi Yu: From higher pressure to lower pressure, no pressure to high pressure
Jin-Yi Yu: Is high pressure low pressure. So it's going to move like this way when a move me quite polar region to equator, a previous co heir.
Jin-Yi Yu: To meet with a woman equipped so nature, try to mix this decrease this temperature difference for producing when and the reason you have queen is because of temperature difference and
Jin-Yi Yu: co author musician opportunism doing is trying to smooth the temperature difference right and we are going to find out.
Jin-Yi Yu: Based on the physical nature fail to bring Kalia all the way from equator to
Jin-Yi Yu: From the equator.
Jin-Yi Yu: Nature fail to do that right now. I just saw a black, green call air from Port we created a brain warm a funny question to Paul. Then I'm going to mix.
Jin-Yi Yu: Reduce the temperature different difference between these two region in nature. Fine order it cannot do that by one or two and also all the way through the South. Anybody know the reason
Jin-Yi Yu: Why nature cannot do that on earth because we are on earth. What is the keys. If you are looking if you stay in this in the space and look at us. Hi. I want to describe this
Jin-Yi Yu: One characteristic is a call. It is a sphere, right. It's coverage on the surface. What is a Deanna important characteristic of US anybody if you're looking. Look. Look at this person from space.
Jin-Yi Yu: It keep on rotating right because we push the air from high pressure to lower pressure on a rotating subject the surface of Unitarian sector.
Jin-Yi Yu: Then something comes in to stop the echo all request from equator, the poet poet liquid enough physical process will be described right
Jin-Yi Yu: And then after we understand how our climate. Okay. How does the creation of time, you know, thermosphere in ocean. Right. Which way one water co authorship around in the Pacific in Atlantic
Jin-Yi Yu: Then we can help each other because all these security moving around, is how that if you're driving a car.
Jin-Yi Yu: The front wheel and real quick connect with each other through a lot of different component and those component our situation. So whenever the from who you hit a rock.
Jin-Yi Yu: Then the real wheel, we are feeling and the whole car will respond to it based on the structure of the car and based on our circulation in our atmosphere in our ocean our premise system is going to respond to any of his last minute.
Jin-Yi Yu: How can we system need to respond to any disturbance either increase the amount of carbon dioxide or change the solar
Jin-Yi Yu: Radiation two hours into the opposite shake that was going around me son or daughter killed an angle opposite us
Jin-Yi Yu: So we are going to change how much solar radiation go to our earth is going to keep on changing cannot change. You can change until to the opposite shake copy
Jin-Yi Yu: Colors around son or to throw a theologian angle of us or two to human being, burning driving car increase carbon dioxide inside that I must be either inside from our climate system or outside
Jin-Yi Yu: From sort of forcing our climate. Climate change or nipple response to whatever forcing disturb our equilibrium state and whenever the current system is Eastern
Jin-Yi Yu: How strong strongly the climate system can response is comparing the system Academy sensitivity. So it was last thing we're going to talk about
Jin-Yi Yu: So three things, talk about in this class basic comes up describing this all kind of system in automatically ocean. The fish called comes up behind a second component. And lastly, based on his timing.
Jin-Yi Yu: For this, the separation and based on fiscal how our system how climate sensitivity committee determine. Okay, so this is just one example of the physical. I'm going to talk about
Jin-Yi Yu: So you don't need a bigger scale by all this equation because I just I use this one this slide, the next slide to tell you one key information that you need to remember even if you are not going to work on fiscal crime area that is
Jin-Yi Yu: The two most important physical law.
Jin-Yi Yu: Important to our current system.
Jin-Yi Yu: They are only there to first his first law all similar dynamic
Lucas: Professor
Jin-Yi Yu: He will
Jin-Yi Yu: Come to you.
Jin-Yi Yu: Because just a minute.
Lucas: Okay.
Jin-Yi Yu: I know of.
Jin-Yi Yu: Motion. Okay, I'll quickly describe to you is do not understand how this tool off are so fundamental to archive any signs up you can understand it later in your career Lucas priests.
Lucas: Yeah. So just before getting to that. My question is how Earth's rotation affects
Lucas: Temperature equilibrium. I didn't get it.
Jin-Yi Yu: He in fact emotion. He affect the the motion when we try to when we have a template. So people to think this is controlled by first of all summer than me.
Jin-Yi Yu: And then when we have temperature difference between equator and how we are very, very cold in Puerto Rican very warm in equatorial region is CO is going to produce high pressure
Jin-Yi Yu: This warm air equator is going to produce no pressure. So, the air is supposed to move from high pressure to lower pressure, producing a window in this way all the way from North Pole to the equator, but also attention is going to tell us you cannot do that.
Jin-Yi Yu: Based
Jin-Yi Yu: Off of the motion. Right.
Lucas: Okay, perfect.
Jin-Yi Yu: Well, so I want to give you an overview, only to feel if you close your eyes and you can imagine how the Earth's climate system look at
Jin-Yi Yu: All this is a valuable piece of paper, you can try based on your vision of your of Erskine the system and all these are system can be systems.
Jin-Yi Yu: The reason we have such kind of those kind of system is based on this fiscal, of course, we're not gonna work on this to physical or to describe it in. But everything and the square all a fiscal conservative here.
Jin-Yi Yu: All these physical process is coming out from this Tola, first of all, some again army and second or motion. So let me answer this question quickly I go into the second loss of this is just overwhelming. Right, so how many even go to my syllabus. I just give you an idea about
What use you.
Jin-Yi Yu: Use you adjust your brain to thinking about how what information to absorb in his class. Okay. So basically, what is the second module. Everybody know that right
Jin-Yi Yu: False F equals ma, right when you are false is going to produce a salvation and our salvation is a change your velocity with time. That's what I'm describing here.
Jin-Yi Yu: Right. And therefore, I mean, Earth has many, many different kind of fall. That's why we need to put a summation, but I spoken about is the key pies for Newton.
Jin-Yi Yu: Tell you as equal to em is a is a change of velocity. How did you measure varsity anybody. So you've I'm here right now.
Jin-Yi Yu: And then move to here by 10 kilometer. Right. So I have a velocity which is going from 10
Jin-Yi Yu: Minus zero over certain time. Right, so I find all my brush. These 10 kilometer perfect example of second per hour. Right. And this is what positive right and going issue and you are not
Jin-Yi Yu: In order. If you want to change this velocity from 10 meter per second to become 20 meter per second. And you need to enforce. Right. So does everybody understand that. But if you apply these physical up to our current system.
Jin-Yi Yu: You try.
Jin-Yi Yu: You try to say, okay, out of pressure here high pressure
Jin-Yi Yu: Low pressure here. Right. And based on faith karma. The force is going from high pressure, no pressure here then which direction you should move
Jin-Yi Yu: Based on new fans, though. Everybody understand that, of course, you have to move the same direction as the or false, right, because f is a vector. He caught in a roster is a matter. But if you look at when a man who come here.
Jin-Yi Yu: Now, if we are high pressure over the United States.
Jin-Yi Yu: How does wink on the moon and a low pressure here in the Pacific Ocean.
Jin-Yi Yu: We find out that instead
Jin-Yi Yu: Instead,
Jin-Yi Yu: We're going from high to low. This is united state. We're in California right here we have high pressure in the United State low price the Pacific Ocean, then we thought we just going to go from
Jin-Yi Yu: East to West that's called easterly when then you go outside of your, your room, your house. Imagine a when you find are actually going going with the Russian when doesn't call out the Russian when going
Jin-Yi Yu: Oh, are you
Jin-Yi Yu: Actually going which way anybody is a high pressure, who is calling co clockwise clockwise this way.
Jin-Yi Yu: Instead, because I imagine instead of getting a win going from high pressure low pressure from east west you actually go from south to north
Jin-Yi Yu: What nature of the women hours doesn't follow freeze on us and second off it emotion, why we came out a hint, or second second arm.
Jin-Yi Yu: Of the motion because when you can describe his second or emotion. This when this velocity has to major by the fixed call the name, you cannot change you are observing coordinate, what does it matter to us because all of those
Jin-Yi Yu: Is practice.
Jin-Yi Yu: And who is the observer who described when you tell you when this from west to east at a 10 meter per second which is us, we are observing observer.
Jin-Yi Yu: Where did. Where do we stand, we stand on top of us for our families, you know, heavy and, you know,
Jin-Yi Yu: Newton's law for UConn to em a this motion has to be described by someone standing fixed in space.
Jin-Yi Yu: Whenever you observe. Open your eyes. Look at the air move from here to here. If someone if you're astronaut he'll call to the space you open your eyes and look at this one.
Jin-Yi Yu: Right here. If you are stand on the earth, you see on the air from
Jin-Yi Yu: Sorry about that. I'm still trying to figure out how to
Jin-Yi Yu: move from point A to point B. If you are standing on earth you tell people, that's the wind from west to east, but you do an astronaut.
Jin-Yi Yu: You frozen yourself fixed in space and you realize okay sorry. The first time you see this care. A is here and a great time. When you look at picture.
Jin-Yi Yu: The P is the other direction. So when you observe f mu to be you observe, not only a move up. You also observed consultation proposed.
Jin-Yi Yu: So you cannot tell us if you wanted to F equals ma is quite hard for us to be changed with this philosophy TV at the velocity has to be described by someone
Jin-Yi Yu: In a space because it's absorbing point coordinate always fix never change with time. But unfortunately, we are going to study our air motion. Our automation by us standing on the Earth's surface, who which people not having some our X y&z
Jin-Yi Yu: Keep on going at a time. So, or when we observe is relative to us rather than rather tip to a fixed coordinate, right. That's why because we have
Jin-Yi Yu: Because we have
Jin-Yi Yu: rotating coordinate. So all the velocity you we describe the when we describe is not absolutely we face on a fixed coordinate and you can talk and only a prior to this, we in motion observed
Jin-Yi Yu: Face I'm obviously coordinate. So in order to still use Newton's law in our locating those we need to reformulate Hawkins.
Jin-Yi Yu: Motion and then by doing that, we find out that the change your velocity is not only based on a false by pressure
Jin-Yi Yu: We have additional force coming up, due to the also occasion. Anybody know what's the name of additional force, we have to improve every time we try to use pressure to protect the when the Russian wispy anybody
Jin-Yi Yu: Parties that additional force coming up this time.
Jin-Yi Yu: After with the right you can. Second. Motion proper are all way to the end. So we can describe out with this you has not subscribed. A there so is wind observed
Jin-Yi Yu: This is called curry august 1 because after we consider this association, we find out that outside California, the wind. Shoot, no problem is correct. You come from south to north. Right. So you can say economically mission is the key. Please call
Jin-Yi Yu: Know one or two people. We are going to encounter, but you are going to hear this Newton's Third Law of Motion anymore because I'm going to describe this in place on
Jin-Yi Yu: F equals ma, and Deanna fiscal concept fiscal luck having our understanding or most of temperature distribution in our
Jin-Yi Yu: Atmosphere in common, particularly at the master is first of all have similar dynamic as I say this, what I mean what I'm saying here is overview
Jin-Yi Yu: You do not need to understand everything I say, Yeah, I just want to tell you this is the comes up, we're gonna carry throughout this 10 week
Jin-Yi Yu: I want you to remember the most important principle and there are regeneration of our current system.
Jin-Yi Yu: Right now, so I asked the CEO longer to remember after you finish this quarter. So I'm just quickly say employee first law of thermodynamics important
Jin-Yi Yu: Because, first off, thermodynamics. A forever energy and into a system and for us now most important energy and into our current system is anybody
Jin-Yi Yu: What is the most important energy come to power our current system sunlight.
Nicholas Pham: If
Jin-Yi Yu: Someone already answered that.
Jin-Yi Yu: All the other good thank you.
Jin-Yi Yu: And then whenever the energy coming to a system or two air. Now we are in the, in the US, you are here.
Jin-Yi Yu: Now, it can be a bloom.
Jin-Yi Yu: Right here on a surface is a three year now you release this fellow co op in Skype. What happened to this portal anybody
Jin-Yi Yu: The problem we have become bigger bigger and bigger right quite become bigger and bigger, and you have to explain it based on first law of thermodynamics, because when we're not a Bronco
Jin-Yi Yu: This extra will not go with the not adding any heat or take any heat out. So the energy call into this balloon from point A to B and C is zero.
Jin-Yi Yu: Her first. No. So let me say, okay, even our energy and into a system that energy, some of this energy will be used to heat up a temperature. Some of this energy or used to produce a walk and this system right now the system we're talking about is polluted.
Jin-Yi Yu: And what walk me or means you produce a force to push the change over your surface S right and I means what are the problem co op. He kept pika, pika as become
Jin-Yi Yu: And for us, that change up the volume is zero. And when he go he copycat so as become positive, positive, positive, and all the pressure surrounding to the room is a force sort of pressure to push
Jin-Yi Yu: The pillow. Keep the problem the same side, but for some reason. The police are getting bigger and bigger and bigger, right. So there must be energy use to help
Jin-Yi Yu: For them to get bigger to to the walk and the first summit and me said you only have two person asked for help to provide energy to look around, Pika.
Jin-Yi Yu: But when I release the room and the room caught up in 10 minutes or 20 minutes, it doesn't absorb absorb and I'll sudden I so nothing, no he call you know equals zero.
Jin-Yi Yu: So, only thing you can take energy from this equation to help room to produce what is temperature
Jin-Yi Yu: It means you need to reduce your temperature and take my energy hours per room temperature.
Jin-Yi Yu: The energy or the temperature of the room and we use the temperature or a problem when you go up and and then you start energy to push the Topeka. Right. So when a problem comes up, we see two things. First, the balloon.
Jin-Yi Yu: Kept Pika. Right. That's because of each time. And what is secondary is a second thing was not is the balloon.
Jin-Yi Yu: Temperature.
Jin-Yi Yu: Drop.
Jin-Yi Yu: Right, so all the meteorology, try to understand why temper, try to predict how much temperature control how much your temperature when a call up and up and up in the sky of aroma. When you guys care about is because when a caught
Jin-Yi Yu: Up in the sky get kuda kuda kuda. Anybody know what is the most important and fascinating scenes going to happen you know thermosphere anybody
Jin-Yi Yu: That meet the Raj care alot.
Jin-Yi Yu: This opportunity produce condensation is going to form crowd. When you have enough enough crowd rain's gonna fall down.
Jin-Yi Yu: WHEN NICOLE emotion is so intense is going to produce thunderstorm matinees so all weather phenomena has his origination from a co op and drop the temperature and how much
Jin-Yi Yu: air temperature drop going on. I can produce condensation quite on I can put us law when for has to do, and you will be controlled by the first law of thermodynamics
Jin-Yi Yu: So anybody can the sense about why are these things important. Okay. That's why I want you to understand. So again,
Jin-Yi Yu: When we come to the summit and me part of the most amount is quite easy question quickly. So this class is not going to go to this formula or a second or motion, the formula, but I want to use this mathematical formula together physical understanding
Jin-Yi Yu: So nothing. Nothing. I'm going to go through this car in this class in aviation related his car his post posed in this
Jin-Yi Yu: Website. This is I'm a school physical science server because I have difficult to put my
Jin-Yi Yu: Teaching material on the canvas University server. So I just keep on maintain everything here. So all reduction recording will also be posted there are. I told you that in the previous email. So here is our example hierarchy of test.
Jin-Yi Yu: Testing. So maybe one day to day after my natural job postings. The video on this. This is didn't you go to the end because I don't want my video or teaching material because this is a request for university. That's why I put a new statement on top of this website.
Jin-Yi Yu: How do I go back to normal.
Jin-Yi Yu: Everybody know how to
Jin-Yi Yu: Get out of this room.
Jin-Yi Yu: Okay so University us or instructed to put this statement right you tell you you're not supposed to sell or Ablow all this teaching material, including that children video to enhance our tech. So have you seen you try to review the electrical here. Now, let me go to
Jin-Yi Yu: The next night I naughty.
Okay, so
Jin-Yi Yu: Sorry, but I've missed on these moments.
Jin-Yi Yu: 11 5050 okay so as the basic idea of this class. Now I'm going to go through the 10 week okay so this time, we need to know the structure opportunity so you know where we are right so
Jin-Yi Yu: The first week is just introduction is quite are kind of system basically everything. I'm going to talk about is our cameras here.
Jin-Yi Yu: How the temperature, pressure, humidity, when circulation to crack because atmosphere is the most important one of the most important part of our kind of system. What is this all about other other must fear. So let me ask you this question. So let's see.
Jin-Yi Yu: So now we have all coming system nine
Jin-Yi Yu: And
Jin-Yi Yu: Okay, how can we system we have an ocean.
Jin-Yi Yu: We have
Jin-Yi Yu: Quite as the meantime, someone asked that. So it's about with full file six depends on our progress we have blend
Jin-Yi Yu: And then we have Thomas fear.
Jin-Yi Yu: Yeah, ocean.
Jin-Yi Yu: Yeah. What is all must fear is a communicator.
Jin-Yi Yu: It bring information from one component of kami system to the other component or is ocean anybody
Jin-Yi Yu: ocean. The ocean is on Mackinac Natalie's
Jin-Yi Yu: Nami Nami stop is hosting a sorry about who I'm working on my laptop. So I'm only seeing my own homes whole screen. I didn't see any chart information you send out so absorber yes is absorber, and then
Jin-Yi Yu: What is the other
Jin-Yi Yu: Know, our ocean.
Jin-Yi Yu: County.
Jin-Yi Yu: The other is ocean is is a battery right and it is a memory of our common system.
Jin-Yi Yu: So let me ask you a question.
Jin-Yi Yu: Hundred years ago and for example today.
Jin-Yi Yu: He who he has a nuclear bomb explode explode. Right.
Jin-Yi Yu: Who is gone, which pow crevices that you can remember
Jin-Yi Yu: That hungry or something. Years later ocean.
Jin-Yi Yu: Ocean is the one corner. Remember this so ocean has a very long memory.
Jin-Yi Yu: And that's why it is important.
Jin-Yi Yu: And what does that mean that means that
Jin-Yi Yu: Am I in the share screen one screen. Are you looking at right now you by
Jin-Yi Yu: Looking at the, look at me. Okay.
Jin-Yi Yu: So,
Jin-Yi Yu: Ocean is surface absorb ocean is a memory about climbing. So when I'm out. My question was going to the future. So you can inverse that sinking or Napa happening today in our ocean is still reflecting whatever happened hungry and solving years ago. Isn't that interesting.
Jin-Yi Yu: So our climate today.
Jin-Yi Yu: Yuki screaming everything tackle coming out from the ocean backpack or may not respond to whatever we're doing right now that
Jin-Yi Yu: Is our memory coming from one solid years ago he remember what happened one sign years ago right that's that's a magazine interesting comes up and ocean also is the battery because absorb a lot of solar radiation.
Jin-Yi Yu: Rain surface cannot keep up energy for long time the ocean can so ocean. We are our kindly. She is a car is a car then
Jin-Yi Yu: Ocean is our battery. Okay, so before I end this introduction. Oh, no, no, I haven't finished the syllabus.
Jin-Yi Yu: Quickly say something first.
Jin-Yi Yu: Our atmosphere ocean. Remember, long, long time. You remember separate years one
Jin-Yi Yu: Mapping
Jin-Yi Yu: PowerPoint.
Jin-Yi Yu: Everybody still meeting.
Jin-Yi Yu: My system.
Jin-Yi Yu: Okay, we're here.
Jin-Yi Yu: Remember only 10 days of memory, what happened 10 days ago hose. You remember years ago 2000 years co
Jin-Yi Yu: And then remember these memories Harlem anybody
Jin-Yi Yu: One to two seasons.
Jin-Yi Yu: So if you go outside to check the soil moisture in California. You remember what happened in two seasons ago summer or spring or even after the last
Jin-Yi Yu: Winter. He doesn't remember anything happened before that. But if we have when growing very strong over Pacific Ocean 10 years ago or she may still remember
Jin-Yi Yu: So those are memories in some fashion first prize got the square thermosphere then we're going to turn on a samurai to heat the power our current system and so will describe how the sunlight affect our temperature everything and then we'll realize one thing that how
Jin-Yi Yu: Tommy system benefit and that if we just based on a solar radiation. How come he is currently the frozen Coke, but our
Jin-Yi Yu: Planet Earth is not frozen is because we have greenhouse effect. So we could describe what is a field that with the aging process that allow greenhouse effect will happen in our system. And then we are going to describe quickly when energy reach from purple atmosphere to the surface.
Jin-Yi Yu: It hides upon our factory service energy. So if you're walking on the plane service group at a department and you may, you may your walk and this
Jin-Yi Yu: comes up a lot for for our group, you may not walk around that. Then I'll describe everything with this quote here has no motion. Okay, we are going to talk about the motion after we can do this week, big fun and that's the week I'm going to after that we am going to have a meeting.
Jin-Yi Yu: And then we'll go to the ocean circulation. Anybody why ocean chapter has to be Co after atmospheric chapter
Jin-Yi Yu: Anybody know because all emotion in ocean is driven
Jin-Yi Yu: Midtown won't cover chapter two and sweet. When a chapter
Jin-Yi Yu: Called contrast the question again. I don't get a question.
Jerry Lin: So yeah, so, so, so there's that.
Jerry Lin: Met him was from one of his 146 was a typo or
Jin-Yi Yu: What do you
Jin-Yi Yu: Think is a
Jin-Yi Yu: Syllabus
Jerry Lin: There's next members chapters 1.6 I think so. Are you not covering chapters two and three.
Jin-Yi Yu: Probably last time I taught this class I was behind schedule something
Jin-Yi Yu: nutcase. Now just curious.
Jin-Yi Yu: Very good. I'm using the tablet to this.
Jin-Yi Yu: Seems yet.
Jin-Yi Yu: Even a practice before
Jin-Yi Yu: Laughter Okay, then the core anything motion in order to emotion, you need to have when
Jin-Yi Yu: And run for right ocean security driven by wind and rain for from the chemistry. So we were talking about, but I must paper circulation and ocean no talk about highs. Right. And these three chapter
Jin-Yi Yu: Well, and the whole discussion of how first climate system and we 910 and 11 actually the last week or two for the party can be changing system at any other question, Marisa just that the
Jin-Yi Yu: We probably you can just ask question directly, so the microphone because I difficult for me to read them.
Jin-Yi Yu: Chat Room. Okay, so I'm going to go to the first chapter.
Jin-Yi Yu: The atmosphere so I only have 20 minutes. OK, so now this is the table content in a textbook for
Jin-Yi Yu: This introduction you tell you what is it must be ocean then surveys, then, to tell you how I must be temperature institutional cried how Otter must Franco composition look like
Jin-Yi Yu: And then humidity look back and now it's become part of our some fiscal constant hydrostatic parents, which is related to temperature and pressure right why we put the
Jin-Yi Yu: Tennis at the moment to put on point for after 1.2 1.3 because when we talk about it must be temperature is T will talk about it must be composition is the mass
Jin-Yi Yu: And mass is going to put this pressure and temperature and pressure, you know, the must fear is to spiritual in a vertical direction is related
Jin-Yi Yu: Through this fiscal. That's why when you talk about hydrostatic parents and with other with water, no water. We still have everything here, but we must be is very good.
Jin-Yi Yu: Sir, yes.
Lucas: We cannot see your screen.
Jin-Yi Yu: You can see my screen. Sorry about that. Okay, let me
Jin-Yi Yu: Get out of
Jin-Yi Yu: And show. Yeah.
Jin-Yi Yu: What did you see
Jin-Yi Yu: Can you see me see the
Popcorn. Oh, yeah.
Lucas: Yeah, we can see the low
Jin-Yi Yu: Yeah, I was saying what temperature, composition and somewhat hydrostatic parents and for humanity and then the body, including climate system or a general property of atmosphere and then very quickly. I'm the ocean CrossFit. And they service.
Jin-Yi Yu: Now how those kind of system, as I mentioned, Potter must be a communicator ocean is absorber of somebody then absorber ocean is a memory keeper is a battery and insidious is how
Jin-Yi Yu: Tectonic Plate and this one we're going to talk about, but this one is very important to explain a lot of timing change Armenians ears high scale.
Jin-Yi Yu: And the sundial.
Jin-Yi Yu: Forcing we're not talking, we're talking about who actually talk about we'll talk about race certain sovereign year for some for some and 2.3 thousand and 100,000 Series seven year cycle that's going to produce the
Jin-Yi Yu: impact our programming. So, this one and this one perfect paleoclimate and this cause going to focus impacting inside with impacts.
Jin-Yi Yu: And then when we have energy comes in, he will lead candy machine will convert this energy into a kinetic energy to try motion.
Jin-Yi Yu: Whenever we are motion. We're going to move things around all these components produced three major cycle global energy cycle group or water cycle group or biology or chemistry cycle.
Jin-Yi Yu: Because we have these cycles through the global region, we can maintain. How can you system in the stable in equilibrium and sustainable way for a long, long time.
Jin-Yi Yu: So the main platinum power of this chapter is that hemisphere.
Jin-Yi Yu: So now, first we need to have a vision how thick or how thing is our must be so the textbook, tell us that our Otter must fear is Barry thing.
Jin-Yi Yu: Why it is very thing because this is a compare to be synchronous soda pose has
Jin-Yi Yu: Radius or six songs and 400 kilometer in our automatic we only have three high hottie. Anybody still remember why I say hands free to two 150
Jin-Yi Yu: Kilometer right so this 100 kilometer a is lying spreading around on this earth circle has a radius of 6000 that's why all at the ministry is considered very racing through spread throughout how
Jin-Yi Yu: On the surface, and why need to emphasize how thing that must be a is because can bring to a very important concept.
Jin-Yi Yu: Because how are the most fear is racing ratio. So whenever a move around and this because I'm a very theme there or most of the emotion is movie, east, west, north, south horizontally.
Jin-Yi Yu: So how atmosphere has a very, very strong horizontal when him very, very weak vertical we. So are you when we, when is always greater
Jin-Yi Yu: Is much, much greater than vertical when you throw these cars. Whenever I say you is east west when
Jin-Yi Yu: Whenever I say V is no sauce with whatever I said W is a very common again. Everybody remember this. So this is the first concept, you need to remember this is what I call knowledge and typically how strong is our wing. How is an auto 10 meter per second.
Jin-Yi Yu: And what is the order of Alberta Cohen is only one center meter per second. So if you have a pen meter per second, the body by one center meter per second is about 1000 so how
Jin-Yi Yu: Can I see something
Or hear his see
Jin-Yi Yu: The horn gumbo. In Speak Out wines thousand times greater than the vertical when. And the reason we have some from Toronto. So we were calling is because our atmosphere is very think that's a key concept, but you need to remember it must be 100 kilometer.
Jin-Yi Yu: Ask you a question. Can we say there isn't any how thick How deep is all must be a who can say that for
Jin-Yi Yu: The Pacific Ocean how inside, California. How deep is the person who can say that because ocean has very career fair rock on the
Jin-Yi Yu: Ocean floor and very courteous see Dave. So we know exactly how deep the ocean us, but I must be is a different story because atmosphere doesn't have a very clear Apple age.
Jin-Yi Yu: At MSP so the most pure info here is service only call echo, echo, echo, echo, echo thermosphere
Jin-Yi Yu: Outside the top, you still have some more some more some more some more. So it is very difficult to clearly define how thick of it must be here. That's how we say always say 100 to 100 kilometer.
Jin-Yi Yu: And now look at this picture here in this in this PowerPoint.
Jin-Yi Yu: Here is that
Jin-Yi Yu: So we're looking into her horizontal horizon. So this also face. So we see that this is what anybody. This is troposphere.
Jin-Yi Yu: At the most because and then you have meant Beeston stratosphere missiles fear thermosphere so it must be for this much, but we see that all these bracket we are, what is the oddest pricing has cloud all a vertical margin, up and down, up and down, up and down petition weather.
Jin-Yi Yu: And climate is only mostly inside this very thing troposphere, which is
Jin-Yi Yu: This there is only about 10 kilometer sort of co author must fear is from here, maybe 150 kilometer.
Jin-Yi Yu: So what we really care the most is the lowest 10 kilometer. Okay, maybe you go up a little bit to the stratosphere, which here is our 50 kilometer last I remember you should remember, you should be able to tell people if we go out to, for example, as a go to 80 kilometers.
Jin-Yi Yu: Away oil or are we, I think we are somewhere high above the area we are interested in listening assembles Mesosphere
Jin-Yi Yu: If I say I'm only 20 kilometer away. Is it as in a low part and middle part of the stratosphere. So last number. If you need to remember our code, go back to this number again.
Jin-Yi Yu: Our troposphere core fan surface Potemkin Amina our stratosphere go from 10 kilometer to 50 kilometer. OK, so now that's
Jin-Yi Yu: How it must be look like and then inside see on the surface and this is how this is much more difficult to look and then inside our MSP we have
Jin-Yi Yu: Troposphere, stratosphere. So spear depends on temperature distribution or you we want to separate atmosphere based on their electricity you a separate
Jin-Yi Yu: Go part of the mass fear is not our it's not our nice so you won't affect me electricity communication, but somewhere about maybe at kilometer.
Jin-Yi Yu: Or across 100 kilometer. We were pioneers fear and then if we look at the composition of air. He says surface near the surface.
Jin-Yi Yu: Copper outside my baby. He will Maxwell Maxwell Maxwell nice because we have troposphere, keep on turning over 10 million mix mixing. Everything is amiss, we call the stratosphere, not as well me express to have some security.
Jin-Yi Yu: And then compliments on sphere. And when you go to very high apart. So most fear here.
Jin-Yi Yu: You see that the scenes and that will mix. So somewhere from Mesosphere two summers fear about at Canada is not well mixed. So we call hydro sphere.
Jin-Yi Yu: Or you must have a pillow at cannot be that I will mix bloody will mix because the homeless fear. Okay, so this is not important. So criminology goodness I say this class is build out your library of vocabulary. Now read it to fiscal cramming ok now let's look at the second
Jin-Yi Yu: The first story. You need to be able to tell. That's what kind of a commercial. We have the composition, why we care about what kind of muscle, we have
Jin-Yi Yu: Anybody may ask you, he will. He will now take us spaceship go to another planet. Now, we never visit before, but you want to study the climate of that pregnant right. You want to know.
Jin-Yi Yu: What happens without harming
Jin-Yi Yu: The planet. So we know he has he has atmosphere. And now we are here, the spaceship.
Jin-Yi Yu: You know, you would look into this planet. So, first thing we want to finalize what can it must be this planet.
Jin-Yi Yu: Because depends on what kind of a composition inside the thermosphere is can determine what kind of warm or cold climate, please premier is coming
Jin-Yi Yu: So that's the first thing we'll find the final for any planet climbing is what is the composition of is MSP
Jin-Yi Yu: For our atmosphere. The composition of course anybody is 80% of nitrogen and the second abandoned cast is oxygen and then Arca right
Jin-Yi Yu: Or is only about 0.04% very, very, very small percentage of atmospheric gas is contributed by carbon dioxide massing nitric oxide hydrogen. Also, she also mapping
Jin-Yi Yu: Natural xi carbon dioxide. And it also what
Jin-Yi Yu: What does the last name. Remind me are all for kind of guess
Jerry Lin: Anybody greenhouse gases.
Jin-Yi Yu: Greenhouse gases. Exactly.
Jin-Yi Yu: And only those gases can affect the absorption transfer of radiation in our current system. So, oxygen, nitrogen and aka even though they can
Jin-Yi Yu: Become a 99.9% of our customers fear they do nothing to our priming energy transfer our climate is not console is not battle is not interfere by last major cancer is
Jin-Yi Yu: Possible only in the very upper part of must be our atmosphere coming is the funny part is small percentage of cases, it does the first concert. If you
Jin-Yi Yu: Remember me two minutes. So I'm gonna fake cleansing. Okay, so now we want to. It's free.
Jin-Yi Yu: For everybody AFTER HE IS HE IS HE HAS A 200 why we have such kind of atmosphere quite on Amazon has so much energy so much oxygen and I can before we talk about our time important gases.
Jin-Yi Yu: So this is Tony. I'm gonna talk about beginning nephew thing. So I want everybody to be able to tell a story from after this class one story is why we have such kind of atmosphere.
Jin-Yi Yu: Has fun story second story is why we only reserve, although hole in a over the South Pole, while we observe. Awesome. Whoa, over the North Pole.
Jin-Yi Yu: This is the second story. I want you to be every year after this corner and reach. True story, the beaver some refresh your preschool understanding. Understanding of the physics process in our climate system polka polka beginning next Tuesday hundred students from here.
Jin-Yi Yu: Anybody has any other question.
Ved Bhoot: A professor ago and questions.
Jin-Yi Yu: Yes, please.
Ved Bhoot: Do we have any homework for this week.
Jin-Yi Yu: No, the first home. Oh well, be sure. Next thing.
Jin-Yi Yu: It says they have than
Jin-Yi Yu: Anyone else
Jin-Yi Yu: Okay.
Jin-Yi Yu: As I said,
Jin-Yi Yu: The lecture serve a purpose to highlight what I want you to remember to understand right
Jin-Yi Yu: But with my accent and with my talking style. You may not be able to get the whole story so priests. We your textbook or even Coco Okay because I probably or is not
Jin-Yi Yu: Comes up. I tried to emphasize our code to be important for your career when you present your startup as your chemistry, but you want to understand a little bit about OSHA situation.
Jin-Yi Yu: How does every day when then everything will be come back to all these fundamental fiscal concept I mentioned or catch up on me.
Jin-Yi Yu: So I'll see you next Tuesday. And then today since the first day. Oh yeah, those office hours and they're still there. Let's say you have any question.
Jin-Yi Yu: One don't have a meeting with me or explain the detail of the natural to you send me an email, we can meet anytime we choose. OK. And now, that's it. Hi, everybody.
