A lecture (from the French lecture, meaning reading) is an oral presentation intended to present information or teach people about a particular subject, for example by a university or college teacher. Lectures are used to convey critical information, history, background, theories, and equations. A politician's speech, a minister's sermon, or even a business person’s sales presentation may be similar in form to a lecture. Usually the lecturer will stand at the front of the room and recite information relevant to the lecture's content.
Though lectures are much criticised as a teaching method, universities have not yet found practical alternative teaching methods for the large majority of their courses. Critics point out that lecturing is mainly a one-way method of communication that does not involve significant audience participation but relies upon passive learning. Therefore, lecturing is often contrasted to active learning. Lectures delivered by talented speakers can be highly stimulating; at the very least, lectures have survived in academia as a quick, cheap, and efficient way of introducing large numbers of students to a particular field of study.
Lectures have a significant role outside the classroom, as well. Academic and scientific awards routinely include a lecture as part of the honor, and academic conferences often center on "keynote addresses", i.e., lectures. The public lecture has a long history in the sciences and in social movements. Union halls, for instance, historically have hosted numerous free and public lectures on a wide variety of matters. Similarly, churches, community centers, libraries, museums, and other organizations have hosted lectures in furtherance of their missions or their constituents' interests. Lectures represent a continuation of oral tradition in contrast to textual communication in books and other media. Lectures may be considered a type of grey literature.
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.

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...

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.

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...
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...

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...

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...
R.Fizpatricks' problem from his online "Lectures on CM"

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.
