Your little philosophies are really pointless, and you can worry about the pussy, I will worry about gaining knowledge and you working under me:)
This should be basic everywhere but the Uni profs have to make sure that you know it because it is an important foundation that you need to have, as well it is a good way to weed out students.
I don't know if you are in Uni yet, but for all of my courses (I am a honours physics student) the first half of the semester was complete review (with the exception of linear algebra)
@mufc4everch I'm from Europe, so I don't have any deep knowledge about the educational system in the States, but do you normally start college/uni when you're 17?
Where I live, this is also very basic, but at a high school-ish level (different educational system over here). We learn this way before university (we don't have college either). There's no way you could get into a physics course at a university without knowing this stuff (and a lot more, of course).
@Hippogriff9 Well, I'm in canada but I believe the US is the same, you start at 18 or 17 depending on when your birthday is. Mine is late so I started at 17.
@Hippogriff9 I am a physics major and I started university at 17, which is younger than most people but still very common. I learned this in my high school physics at age 15, and it was reviewed the first week of my first university physics class.
From what I understand through speaking with European students, American universities are much less specialized by subject.
Here in the United States rich people receive a good education before college and middle class people receive a good education at some time in their life if they are lucky, exceptional or both. If you pay attention you may notice the professor, at the start of the lecture, addressing that some students will already be familiar with the material. The United States government doesn't want a well educated public, they want a well educated upper class. I hope that answers your question.
@jamiestewart48 Watch out guys, here comes another troll, who has deceived himself into thinking that his nations standard of education is superior to that of the US's.
@jamiestewart48 this is the fucking second lesson in a freshman college class, do you expect them to jump right into quantum theories? stay in your country no one cares
U.S. students may take physics in high school if they wish - I did - most don't, however.
Also, most who take physics in high school, take a "conceptual" non-calculus physics course, so would have to retake it in college if they want a science/engineering track.
@Elzelgator Yes,only the velocity is affected when reversing the direction of travel of an object. Acceleration can be constant throughout the process.
Are you sure ? If it is true then it is really shocking.His lectures are considered among best and there is no doubt about his teaching ability.Prof Lewin is really a good teacher.
This generally should not happen.I am also teaching physics both at Undergraduate and Graduate level since 1992.Sometimes things may not click between teacher and students but 22 is a high number in 1 course.I thank you for providing this information and as a teacher now I will also be more vigilant and make sure I don't have such high failure rate.But again I admit Prof Lewin is a fantastic teacher and an inspiration for all serious students.
I didn't study @ MIT, however I was taught that acceleration was a change in speed or direction. so Wikipedia says"The rate of change of velocity is acceleration" so I guess that was correct. This guy is fun..I like him...anyone want to get me into MIT? I wanna met Robin Willams!
@hevad You push the chalk into the board and let it skip. Speed and pressure determine the dot spacing and dot thickness. Faster and lighter = wide thin dots. Faster and harder is wide thick dots. Slower and harder = closely spaced thick dots. One of my Comp Sci profs Jacques LaFrance at ORU taught me :)
Wow that was amazing lecture! I really liked how Dr. Lewin described the difference between velocity and speed. Because at school we don't actually derive where did it come from :S
You actually can't say which is bigger in matter of velocity because how do you say which direction is bigger. He kind of said that when he mentioned that he wouldn't like to do so.
This level of physics is teached at Swedish high schools. But its a good thing, students from most of europe can skip these classes and immediately go on with more advanced classes.
@boydanlaz Displacement & Velocity are both vectors, vectors are things that have both a magnitude (length) and a direction (E.g. East). Displacement is the change in position while velocity is the measurement of the rate and direction of change in position of an object.
Free energy is finaly here!But the Big corporations spend millions to ensure that information does not spread to the masses,Get a motor that works with the power of magnets only at LT-MAGNET-MOTORdotCOM ,Big change is comming soon!

Wow thanks Professor Lewin, if all my teacher as you as good in teaching, i believe my Nation will grow up more and more again, love you so much. arip Nurahman from Indonesia.
Kinda neat that you can learn physics from MIT without the hit to your wallet. I don't really understand all this but it's an interesting lecture. He reminds me of "Doc" from Back to the Future!
This man is a brilliant professor. I have heard many lectures where the professor injects his political views into the class. Professor Lewin mentions that he dislikes guns, but he uses it as an example in his class. The thing that I love about Physics is that no matter your political and/or religious beliefs, they cannot be injected into the science.
@Enooraa I believe that God created the universe. I believe that the big bang may have happened and may have been caused by God. People ask me why I think this because the universe is hundreds of millions of years old. My reply may be naive, but God exists out of time, therefore a day for Him could surpass what we can comprehend.
@DeltaBravo1216 I was'nt talking about believing in God but about creationism, that states that the earth was created by God 6000 years ago (i think). And people who are religious in that way injects their beliefs in science, thus denying the big bang and many other things...
(Sorry if i'm not being very clear, but english isn't my first language.. :s)
@DeltaBravo1216 I don't understand how you or anyone see a need for some kind of god. Besides, if god created the universe and everything in it, who created god, and who created that one, and so on. Don't you realize how stupid the idea of a god is?
@JmSantos78 Any thought of how the universe was created is stupid. Humans cannot comprehend it whether you view it religiously or scientifically. You describe why it is dumb to view it religiously, but I want to explain why scientifically is stupid. Law of Conservation of mass states that matter cannot be created nor destroyed. This is law. Meaning it cannot be broken to the understanding of humans. Well where did all the matter come from? Neither way makes sense and thinking about it is idiotic
@ff7masta When you solve the mysteries of the universe, tell me. If you go down that road and your whole life is wasted as you research every aspect and every detail of all possible reasoning then you realize that you haven't come up with an answer, think of me. It's not useless to tell people the things that are impossible are impossible and not to waste there time with it. I'll tell you that it's impossible to melt your body and live. Care to prove me wrong?
@fadenkreuze Some men and women "wasted" their entire life in the study on electricity. Turns out that every generation they went closer. You know, the airplane was a complete mechanical novelty in one of the Da Vinci's notebooks? Then these guys spent more than 5 years optimizing the wings and flight control from the first powered airplane in the world. They did kites, gliders, prototypes.
I would like to isolate you from scientific progress. Go live in a cave.
If you change the polarity of the earth, is it possible for the earth to flip? If then could it be possible the Ring of Fire may become the equator is such a change?
The earth doesn't flip. Sure the Ring of Fire may be at the equator, but that's just due to plate tectonics, not pole reversal.
Pole reversal is either caused by the magnetic field lines being disrupted a result of chaotic motions of liquid metal in Earth's core or that external factors may trigger a pole reversal, such as plate tectonics. They could cause pole reversal, not the other way around. But nobody knows for sure.
Why would he not be a fan of guns? Better question, why was this interjection needed? It wasn't. That was a completely unnecessary, totally subjective comment. Guns are every bit as much of a useful tool as a chalkboard, or a hammer, or a wrench, etc. It's JUST a tool. Don't ruin good scientific discussion by disclosing personal (irrational) prejudices. I hate when teachers do that.
This guy makes so much more sense than my high school teacher ever did in finnish.. I learn now much better even though my native language is finnish :D Good lecturer!
Well that's common and to be expected - in school you have to make certain simplifications and a lot is left out - in college/university or whatever you more of the basics and no simplifications are made just for the sake of "dim witted pubils" ;)
I'm serious: the deeper you go the more students that really want to know the "why" will gain.
I always asked the "why" in school and always wondered if I was just to stupid to crasp those stories.
im only 15 in high school as a freshmeat and im able to learn stuff from him i and i have a ''D'' in math! i so love this and watching all of these vids i can.
Wait... so you're 15... you're a D student in math... which means you would be in something like Algebra I... so tell me how you are able to understand the v=dx/dt stuff.
It doesn't require mathematics at a terribly high level, but it was just hard to believe, considering the failure in algebra (which is way, way easier in most cases than a derivative).
@beefjilvin It's basic algebra and some logic. speed is a change in distance over time. You can use delta to have a difference between two measurements. You may rearrange the equation, it's just one of those generic z=x/y type equations. I ended up memorizing the one that I use the most, just because I was using it like every 4 days.
funny, in our country we learn this stuff before we go to a univerity, or something similar. his explenation for the "free fall" could have been made more understandable.

@DeltaBravo1216 I was'nt talking about believing in God but about creationism, that states that the earth was created by God 6000 years ago (i think). And people who are religious in that way injects their beliefs in science, thus denying the big bang and many other things...

@DeltaBravo1216 I don't understand how you or anyone see a need for some kind of god. Besides, if god created the universe and everything in it, who created god, and who created that one, and so on. Don't you realize how stupid the idea of a god is?

@JmSantos78 Any thought of how the universe was created is stupid. Humans cannot comprehend it whether you view it religiously or scientifically. You describe why it is dumb to view it religiously, but I want to explain why scientifically is stupid. Law of Conservation of mass states that matter cannot be created nor destroyed. This is law. Meaning it cannot be broken to the understanding of humans. Well where did all the matter come from? Neither way makes sense and thinking about it is idiotic

@fadenkreuze People who think like you do inhibit the progress of science. "It can't be done. Give up. Useless."
You know what's really useless? You.

@ff7masta When you solve the mysteries of the universe, tell me. If you go down that road and your whole life is wasted as you research every aspect and every detail of all possible reasoning then you realize that you haven't come up with an answer, think of me. It's not useless to tell people the things that are impossible are impossible and not to waste there time with it. I'll tell you that it's impossible to melt your body and live. Care to prove me wrong?

@fadenkreuze You really are a sad case. Not an ounce of scientific integrity within you.

@fadenkreuze Some men and women "wasted" their entire life in the study on electricity. Turns out that every generation they went closer. You know, the airplane was a complete mechanical novelty in one of the Da Vinci's notebooks? Then these guys spent more than 5 years optimizing the wings and flight control from the first powered airplane in the world. They did kites, gliders, prototypes.
I would like to isolate you from scientific progress. Go live in a cave.

@fadenkreuze You cannot melt a body since we are carbon based life forms thus we burn and don't tell me you were joking.

If you change the polarity of the earth, is it possible for the earth to flip? If then could it be possible the Ring of Fire may become the equator is such a change?
nathan1cast 1 year ago
@nathan1cast
The earth doesn't flip. Sure the Ring of Fire may be at the equator, but that's just due to plate tectonics, not pole reversal.
Pole reversal is either caused by the magnetic field lines being disrupted a result of chaotic motions of liquid metal in Earth's core or that external factors may trigger a pole reversal, such as plate tectonics. They could cause pole reversal, not the other way around. But nobody knows for sure.
I just know the Earth doesn't flip.

Why would he not be a fan of guns? Better question, why was this interjection needed? It wasn't. That was a completely unnecessary, totally subjective comment. Guns are every bit as much of a useful tool as a chalkboard, or a hammer, or a wrench, etc. It's JUST a tool. Don't ruin good scientific discussion by disclosing personal (irrational) prejudices. I hate when teachers do that.

@bluegrassaficionado men of knowlege are usually adverse to weapons of destruction and i am glad of that, deal with it

@DarkShroom dont be so quick in your thinking. it is "men of knowledge" who invent these weapons of destruction in the first place.

This guy makes so much more sense than my high school teacher ever did in finnish.. I learn now much better even though my native language is finnish :D Good lecturer!

Well that's common and to be expected - in school you have to make certain simplifications and a lot is left out - in college/university or whatever you more of the basics and no simplifications are made just for the sake of "dim witted pubils" ;)
I'm serious: the deeper you go the more students that really want to know the "why" will gain.
I always asked the "why" in school and always wondered if I was just to stupid to crasp those stories.
.... I studied math in the end ;)

im only 15 in high school as a freshmeat and im able to learn stuff from him i and i have a ''D'' in math! i so love this and watching all of these vids i can.
i hope they add alot more
jondukesofhazzard 2 years ago 4
Wait... so you're 15... you're a D student in math... which means you would be in something like Algebra I... so tell me how you are able to understand the v=dx/dt stuff.
beefjilvin 2 years ago 11
haha.

@beefjilvin'
Because, you see, v = dx/dt does not require knowledge in high level mathematics.
R4nd0mEvi1 2 years ago
Yes, It's technically just a matter of notation, although understanding the concept of a derivative makes it so much easier.

@R4nd0mEvi1
It doesn't require mathematics at a terribly high level, but it was just hard to believe, considering the failure in algebra (which is way, way easier in most cases than a derivative).

@beefjilvin It's basic algebra and some logic. speed is a change in distance over time. You can use delta to have a difference between two measurements. You may rearrange the equation, it's just one of those generic z=x/y type equations. I ended up memorizing the one that I use the most, just because I was using it like every 4 days.
