Lectures Definition and 343 Threads

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...

my exploration of relativity followed by first reading various books which failed to explain to me how relativity worked but built a strong feel of how one can think about it. after which i decided to take the mathematical way of understanding it for which i am going on with the prof susskind's...

I know this is an odd topic. The Feynman Lectures seem to be universally acknowledged as a great way to learn and grasp some of the simplest and most difficult concepts in physics. I am almost done the first volume and I really am enjoying the lectures. The odd thing is, I can't put my finger on...

What is it about the Feynman lectures on physics? Everywhere I hear about them they're refer to as great, awesome for science and what have you. But what makes them so revered? What sets them apart from say the Suskind Lectures or MIT OCW? Perhaps I am to young in my career to have learned...

Hi, I live in the U.S. right now, but in a few months I'll be moving to another country. It will be much harder to get books like the Feynman lectures there, so I was wondering if I should get them now (or even at all). How good are they? Are they very difficult? How advanced should I be in...

Hi all, I've done a web search but came up empty so here I am. Anyone know if there are any videos online of a Julian Schwinger lecture (even just a clip)? I've heard he was a brilliant speaker and was interested in watching. Thanks!

I am wondering if these are typically what engineering lectures are like (more or less ) found these on youtube and its from UCBERKELY http://www.youtube.com/watch?v=Gkdn7n0f_GQ&feature=relmfu http://www.youtube.com/watch?v=fIvT8_iSX2A&feature=relmfu...

Last year I got volume 1-3 of the Feynman lectures but as a soon mathematics major I think it'd be appropriate to read more mathematics lectures (and more enjoyable). Is there anything similar I could ask for for my upcoming birthday? Thanks,

need lectures of good references of AC synchronous and links if you have ... and I wonder why the field of it is DC ?

Hi, Can anybody recommend me a good video lecture series on Introduction to digital logic design? I want to watch these videos before going to class.

if possible could you tag some good video lectures may be feymann or any other good source..thanks...!

Hello, I'm wondering if there are a series of books, analogous to the Feynman Lectures, for Electrical Engineering. The Feynman Lectures (as many of you know) are clear and concise, and nutshell a great deal of typical undergraduate study. A student can read these lectures from cover to...

I got a 3.9 (out of 4) in first year engineering without going to a single lecture. Can I get a 4.0 easily if I go to all my lectures in 2nd year and beyond?

It is better for you to have studied "Feynman lectures on Physics Vol.3", because I cannot distinguish whether the words or expressions are what Feynman uses only or not and in order to summarize my questions here, I have to just quote the contents of the book. However, one thing I notice is...

So my professor's lectures are very boring, and I almost learn nothing from the class. I can't stop myself falling asleep during this class. I could keep my laptop open or read the textbook during the class to keep myself from falling asleep, but I feel that might be disrespectful, even thought...

Hello all! I'm just out of high school and have got a few months before college begins. I think I'm fairly good in high school math, and now I've just started self-learning Single Variable Calculus (Calc I) from MIT OCW Scholar. I love Physics, and aim to be a physicist someday. I...

I am doing electrical engineering. I wish to know about Electromagnetics fields. I read little bit in Richard Feynman's lectures on Physics and I liked it a lot. Actually he had written about Emf in Volume 2. Will I be able to understand Volume 2 without seeing Volume 1? Thanks in advance.

Have found a Youtube video: The Reason for Antiparticles: The 1986 Dirac Memorial Lecture Other than the book of the lecture, which is difficult to get hold of cheaply, does anyone know if this material on why quantum mechanics and relativity together require the existence of antiparticles...

I've observed that lectures, whether for history or physics, last between for at least 45 minutes, often going beyond the 60-minute mark. I highly value the help gained when learning from a good instructor but sometimes, I fail to understand why college lectures are so long. Even for...

hi! i would very much like to have the "Lectures on Comlex Manifolds" by Philip Candelas. It was recommended by an instructor of a course on complex geometry i took some time ago, but sadly its out of print and not in our library. Does anyone has this documents in electronic form?

This isn't really a 'problem', I'm just trying to follow Feynman's reasoning in section 18-2 of Volume 1 The Feynman Lectures on Physics. I've attached a png of the paragraph in question. I have 2 issues with this: 1. If the length OQ = OP, how can there be a right angle at P(x,y)? 2. I...

In 15-4,Feynman tried to explain why the rod perpendicular to the motion does not shrink."How do we know that perpendicular lengths do not change? The men can agree to make marks on each other's y-meter stick as they pass each other.By symmetry, the two marks must come at the same y- and y'-...

In 2-5, an analogy is given for electromagnetic field: two corks in water, and the effect of jiggling one cork on the other (probably the up and down motion). Now, that sounded more like water is a medium propagating the energy. But the electromagnetic waves require no medium for propagation...

TEDxCaltech was an event at Caltech where invited speakers gave talks in honor of Richard Feynman. The speakers are experts in the fields of biology, physics and nanotechnology. Among the speakers are Leonard Susskind, Scott Aaronson, Sean Carroll and more. I can't even say which of the...

in chapter 32 section 4 on electromagnetic waves, near the end he writes since \lambda = \frac{2\pi c}{\omega} then \Delta\lambda = \frac{2 \pi c \Delta \omega}{{\omega}^2}. i understand the first equation he writes but then the second one i am having trouble convincing myself how he came up...

Hi all, I am looking for some more information about the experiments that Feynman describes during the lectures that he gave in Auckland which can be viewed on the vega science trust website. The first experiment is where photons are transmitted or reflected by one surface with a second similar...

Here's a lecture I found interesting: http://www.youtube.com/watch?v=zosrQYmxL2Y&feature=plcp&context=C30c8af9UDOEgsToPDskIJ0do9BlfSHEhq6NgCVbA4

With Leonard Susskind's Stanford continuing ed course, does the "New Directions in Particle Physics" start where the Quantum Mechanics series ends, covering QFT or is there going to be a separate QFT series from him?

A classmate approached me last week (after class) and asked why I ask about things that probably aren't going to be on the exam. I told him that it helps me understand things on a deeper level. He then said, "Do your understanding on your own, because it makes things confusing for the rest of...

Hello all, I am looking for video lectures for upper-level mathematics courses. In general, late-Undergraduate and early-Graduate courses of any kind. If you post in this thread, please do not link videos for Calculus I, II, or III, or first courses in Linear Algebra, ODEs, Complex Variables...

I am just finishing up an undergraduate course on quantum mechanics, and I plan on watching Leonard Susskind's online lectures on http://www.youtube.com/playlist?list=PLA27CEA1B8B27EB67"over winter break. Does anyone have any suggestions about a textbook that may be good to read along with the...

Just in case you don't know he lectures physics for Stanford . Do you think they are a good resource for self learning. I don't have any intention to self teach myself QM but I like listening to them.

*Sorry about my bad english, I'm not a native english speaker.* To make a long story short, my university uses this book: http://www.amazon.com/dp/0132130068/?tag=pfamazon01-20 Unfortunately this class isn't teached using a normal approach, and we are supposed to learn everything by...

I'm doing well in my Calculus course, but I drive 15 minutes to get to class and back. I really think I should utilize this time. Can anyone recommend any lectures I can listen to while driving? I'm sure it can also really help get the concepts down. Anything would be helpful. Thank you in...

In footnote 1 of his recent paper http://arxiv.org/pdf/1109.6462 Steven Weinberg promises "1. This point involves too many issues to be treated adequately here. The author’s views on the present state of quantum mechanics are spelled out in detail in Section 3.7 of Lectures on Quantum...

Hi, I am wondering how different the Feynman Lectures editions are. I have the option of getting the 1964,1965, 1970, and 1989 editions. Obviously getting the latest of those editions is the best, however I heard that the 2005 edition is the best edition with all the corrections and the one...

I'm reading Feynman Lectures on Physics Volume 2 Chapter 39 on elastic materials. Equation 39.22 relates the elements in the elasticity tensor to the Young's modulus and the Poisson's ratio. I have no clue on how to get these relations myself. For example, for C_xxxx, I think it should tell...

Hello, all. My colleagues and I are currently working on an exercise book for The Feynman Lectures on Physics (FLP). This book will include about 1000 exercises from the original Feynman Lectures course as taught at Caltech, covering pretty much the entire range of topics in all three volumes...

Hi, Can anybody recommend me a good video lecture series on introductory digital/logic design? I want to watch these while I'm on break from my studies. Thanks

Hi all, I've been reading the Feynman Lectures on Physics and I've stumbled on something. I understand the theory but not how they arrived at the answer. It's to do with firing a bullet from a gun and working out the speed it would need to travel in a curve around the Earth's surface in order...

Anyone have any suggestions for video lectures that go beyond the standard overview-for-the-layman or slightly-lower-level introductory courses? A post somewhere on here pointed me to Susskind's "Theoretical Physics: the Bare Minimum" on "iTunes U", which is sort of the prototype for what I'm...

I'm a high school student. I wanted to know if I can go for the Feynman lectures. Please notify me about the mathematical and other requirements for it.

If some pre-med students want to study Physics by watching university-level video lectures on Physics-1 (Classical Mechanics) and Physics-2 (Electricity & Magnetism), what site would you suggest to them? (They already know of Walter Lewin, Ramamurti Shankar and Khan Academy). Can you suggest any...

Question 1: solved! Question 2: Why it's zero? I think we cannot get zero unless it's an exact differential form? Many thanks.
