Lectures Definition and 334 Threads

For some reason, I'm having trouble with what I feel should be a relatively simple derivative to take. Feynman is differentiating the potential to find the z-component of the electric field. He has: -\frac{\partial \phi}{\partial z} = - \frac{p}{4 \pi \epsilon_0} \frac{\partial }{\partial z}...

I was wondering where I can find the best quality lecture videos of Walter Lewis. Both mechanical and EM. Most of the videos I find are of low quality and it makes it hard to follow. Thanks.

Which one do you think that is more efficient? I think that lecturers, from the fact of being humans, commit more mistakes than books when they give information because they can forget to transmit important details. Books are written carefully in order to be easy to understand, what's said was...

I'm interested in watching videos of Real Analysis lectures etc. in good quality resolution. Those Harvey Mudd College lectures are valuable but annoying re video quality. Thanks. - Blue

Hey guys, following the brouhaha around mr.lewin's inappropriate conduct, mit ocw has removed all of lewin's course materials from its page. But the lectures are still available on YouTube, thankfully :bow: But the pdfs aren't! Please let me know if any of you have them downloaded from back...

Looking to buy a copy of the Feynman lectures and the millenium edition is the one I am going to buy. I remember reading, maybe I am mistaken, that there was reprint of the 2011 millenium edition. If I am correct, this reprint fixed errors that were found in the 2011 editipn. However, when I...

I am currently in my first year of A levels and we have completed the particle physics parts of this year and by asking my teacher and A2 physics students I have found that next year we will not be going into much more detail regarding particle physics. This left me somewhat disappointed as I...

I am a member of a small group of physics graduate students in charge of a monthly series of public science lectures. The lectures are aimed at local high school students, and we have many high school teachers who encourage their students to attend by offering extra credit. The audience of each...

Engineering student here. Last semester I didn't go to most lectures or tutorials because they were too slow and too boring. However, I see a lot of people say that going to lectures/tutorials is very important. Should I go to them this semester? I averaged an A- last semester (with one A+)...

Just wanted to post a link from Caltech's website hosting the complete Feynman lectures on Physics. All 3 volumes. http://www.feynmanlectures.caltech.edu/

Feynman's first topic in his second lecture on QED is the nature by which light reflects off of a mirror. We work in ##\mathbb{R}^2##. Suppose we have a light source sitting at ##(-1,1)## and a photomultiplier sitting at ##(1,1)##, with a mirror along the x-axis. We also place a block between...

I have the books and audios. But I have yet to find the videos. I am wondering whether they exist.

Hey guys, so this is something that I've been thinking about a lot over the past few years. I'm currently a Physics and Math major at UCLA and I'm relatively doing pretty well in all my classes, but there is something that I have been really struggling with ever since I started college. I can...

I am aware that all three of them are good ones. But, if one is to be picked, which one would it be? I have basic knowledge of mechanics and a little of thermodynamics. I am looking for a book which will further strengthen my basics.

(Not a 100% this goes here but oh well) I imagine there's not a lot of this, since visual presentation is pretty important in these subjects, but does anyone know any good lectures or audiobooks on highscool/Secondary mathematics or physics that one could listen too while taking a promenade...

Hello everyone. My name is Sam and I am an engineering student. I am very interested in studying physics. I am currently using physics by Halliday/Resnick/Krane. I have read good reviews on Feynman lectures but not really sure about its content. Is Feynman lectures a good supplement or is it too...

Hi I can see that MIT, Stanford and Yale have open courses in Classical physics and electromagnetics. Which courses would you recommend for self-studying all the general first year topics at university such as Classical mechanics, electromagnetics, light etc? For classical mechanics I think...

Good afternoon, I am working my way through the Feynman lectures and I am stumped at Chapter 23, Resonance. Specifically, the derivation of equation 23.12. I have followed up to that point but the appearance of tan (theta) baffles me. The equation is below: Any help would be greatly...

In the Feynman Lectures on Physics chapter 28, Feynman explains the radiation equation $$\vec{E}=\frac{-q}{4\pi\epsilon_0 c^2}\, \frac{d^2\hat{e}_{r'}}{dt^2}$$ The fact that the transverse component varies as ##\frac{1}{r}## seems fairly obvious to me since what matters is just the angle...

Hi,so I've just started reading the Feynman's Lectures on Physics on my own recently.By the end of chapter 2, volume 1, it says "This then, is the horrible condition of our physics today.To summarise it, I would say this:outside the nucleus, we seem to know all; inside it,quantum mechanics is...

hi, studying BSc astronomy/physics 3rd year in the UK on part time basis. i am a senior cosmetic dentist by profession, so have limited exposure to what lectures are available around the country. any guidance please? thanks raj

Homework Statement Two gliders are free to move in a horizontal air through. One is stationary and the other one collides perfectly ellastically. They rebound with equal and opposite velocities. What is the radio of their masses? The Attempt at a Solution The answer is 3, how can I...

Hi guys! I am looking for good lectures or books on special relativity and/or general relativity. Thanks in advance for any feedback.

I love Feynman's Lectures on Physics and want to go over them again, but I find there's so much of his character is lost when just reading them. I have found a few selected audio versions of his lectures, but I would like to find the COMPLETE set. I know they exist somewhere, as that's how they...

Hi! Does anyone know where I'd be able to find good notes/ lectures on waterproofing? Specifically for electronic products, if possible? Please provide me with some links if so. Many thanks

I was planning on using Richard Feynman's lectures on physics to study for high school ap tests on mechanics and electromagnetism. I don't know how in depth Feynman's lectures go, since there are no problems but I've heard it works when you're trying to grasp the material. However, I don't know...

Hello, This is a thread to collect youtube lecture series. I would appreciate if you would add your playlists. I tried not to overlap with Khan Academy, but if you have good lecture series that overlap, please share them.Mathematical Logic lecture series: Mod-01 Lec-01 Sets and Strings -...

I study Physics at college and I'm on the third year. Currently, I'm facing a very complicated problem: I can learn advanced math, do complicated proofs, but I simply can't read Feynman's Lectures on Physics. Until now, I just had classes about physics for engineers (Halliday's book), so no...

I have been taking a whole bunch of online courses for a couple of months now, some of which are more challenging to me than others. I don't watch the lectures because they take too long, I usually just stop the video and click on the subtitles to read the slides. Even then I sometimes fail to...

I read the Quantum Physics section of the online version of Feynman lectures http://feynmanlectures.caltech.edu/I_02.html#Ch2-S3 and I don't understand how he can deduce electron momentum from the Uncertainty Principle. I agree that the momentum is uncertain but how can he deduce that it is very...

I read the Quantum Physics section of the online version of Feynman lectures http://feynmanlectures.caltech.edu/I_02.html#Ch2-S3 and I don't understand the problem with the electrons "breaking away from the nucleus". So why can't the electrons just keep going in and out of the nucleus ?

I've been watching leonard susskind's lectures on general relativity on youtube, I'm now at the fifth of them. It is my first exposure to general relativity and so far the lectures are pretty easy to follow. So my question is this, to anyone who has had more exposure to the subject: Do you...

"scalar gravity" -Feynman lectures on gravitation Hi all, I'm trying to understand the following claim from Feynman's lectures on gravitation, section 3.1 (p.30 in my edition). He's considering how heating or cooling two clouds of gas would change their mutual gravitational attraction. I...

Have you ever wished there was a high-quality up-to-date version of The Feynman Lectures on Physics available online? One that could be read with a browser so you could study FLP on your smartphone, tablet, notebook or desktop computer, whenever you felt like it? For free? Well, now there is...

"The Mechanical Universe...And Beyond" - Free Physics Videos Online My physics (Thermo and E&M) professor recommended the following set of lectures from Annenberg Learner, produced by CalTech in 1985: http://www.learner.org/resources/series42.html Scroll down and click the "VoD" button to...

I wanted to start a poll for this thread, but couldn't figure out how to do it. However, I was curious as to what people's experience was with watching Lenny Susskind's multiple marathons of "the theoretical minimum" variety of extended education lectures? Of course, I may be vilified for...

I just recently found a brilliant lectures on rings which cleared so many thing up, and opened a whole deal, or prime Ideal(lol) of insights for me, But for now I will work and develop those insights and for the mean time I wish to show you these video, and hope you find it interesting. Link \\...

Found a nice resource that I don't think is listed in the "Math & Science Learning Materials" section of Physics Forums. It is here, http://www.learnerstv.com/Free-Physics-video-lecture-courses.htm Which is from, http://www.learnerstv.com/index.php This probably belongs in the...

Sound and supersonic motion -- a question from Feynman's lectures In chapter 51, volume 1 of the FLP, Feynman writes Unfortunately he didn't give a justification for this claim. I was hoping someone in Physics Forums could fill this gap in.

Hey guys just wanted some advice. I am an aspiring physicist. My main topics of interest are Particle Physics, Cosmology and Black Hole Physics. I have been planning to listen and study these lectures by prof and great physicist Leonard Susskind...

Are the susskind lectures a good way to learn quantum physics? I am doing just the introduction to quantum physics in high school and we have done: Black body radiation, photoelectric effect, Rutherford, Bohr's, Compton effect, pair production, a lot about de Broglie wave-matter duality...

Hey there, recently been studying Optics in Feynman's book vol.1 and came across his geometrical approach of Fermat's least time theorem and its application on refraction. So he illustrates refraction geometrically like this (attached jpeg for those without the book) and so he goes on to say...

Hi, I was wondering, what would be the smartest solution for recording lectures at university with the following requirements 1. I want the video files to be a small in size as possible (not filling my harddrive to fast) 2. The quality to be good enough so you can see the text on the...

If you find yourself never having time to do the things you want, or if you find yourself procrastinating a lot, or in any way abusing time on a regular basis, then I'd highly recommend you take two-and-a-half hours out of a week, and watch these two amazing lectures by a former Computer Science...
