Lectures Definition and 334 Threads

Hello everyone, I want to find better math note taking software because I am a slow writer and my handwriting is very poor. It is difficult for me to keep up with professors when they are quickly jotting down equations in class. I will take Calculus 2 next semester and I am worried about how I...

611 pages of notes Richard Feynman made in 1961-64 to plan and prepare lectures for Caltech's two-year introductory physics course, later known as The Feynman Lectures on Physics, have been posted in deep-zoomable format at The Feynman Lecture Website. Photos of Feynman giving his...

Hi, I am currently studying for our third year solid state physics course. We follow chapters 1-9 From Charles Kittel's "introduction to SSP" Youtube has a lot of videos on solid state physics yet i am struggling to find any video source for lectures that follow the book of Kittel. I would...

Hello, I am beginning a course in thermodynamics in which we will be using the textbook "Fundamentals of Engineering Thermodynamics" (Moran, Shapiro Et al.). Does anyone know of a video series which covers similar topics as in textbook? I have the textbook, I am just looking for a supplement...

I just finished the intro physics sequence at my college, and I wanted to work through the Feyman lecture Vol.1, with the workbook, over the summer. Does anyone know of any sample curriculum used for this book? Or perhaps, knows a good way to work through the book?

I have Thomas and Finney's book on Calculus for reference. Am I prepared for Feynman's Lectures? I've studied physics for two years in high school.

Ed Witten is famous on his research of speculative theories such as string theory. But recently he has written several pedagogic lectures on "normal" physics, that is on several different physics topics that are not speculative at all. Even though these lectures are not really "books", they are...

Hey, do you guys take notes during lectures or do you just concentrate on the lecture itself and what the professor says? The notes which the professor writes are uploaded to our learn-room on the internet. So I just listen during lectures and look up the script before the lecture so I know...

Do you think people with a high iq or high intelligence go to lectures or prefer to self-taught the things from University ? So instead of going to lectures they learn it without a professor or teacher. Is there a way to say make a conclusion ? Or is it too different ? And some high...

I have been reading Feyman Lectures Volume 1 and I am stuck on the example or proof given in the book about how no machine can be more efficient than a reversible machine. http://www.feynmanlectures.caltech.edu/I_04.html Section 4-2 A very simple weight-lifting machine lifts weights three...

Hello, I just had a quick question. Does anyone have links to online lectures for Upper-Division Electromagnetism? I so far haven’t been able to find much other than a few isolated videos here and there. I’m looking for something that covers Legendre polynomials, spherical harmonics, maxwell’s...

The lecture is here, paragraph 5-7. Feynman is trying to explain how to measure the size of the nucleus. He writes : "Suppose we have a piece of material 1 centimeter thick. There will be about 10^8 atomic layers. Since we don't know the size of the nucleous, how can be possible to calculate...

Hi, last year I've decided to re-study physics starting from the very basis in my spare time. It is taking some time but it has been pretty fun and useful. I'm an engineering undergrad and the most advanced physics class I had was an introduction to QM, but right know I'm more focused on...

Hello. I self-studied and have a good grasp on QM, statistical mechanics and Group theory. Next step is QFT. There are several sets of video lectures on Youtube about this subject and I am asking for a recommendation (I would like a set of videos which involves the unitary IR of the Poincare...

The Feynman Lectures on Gravitation is a famous book. There are originally 27 lectures but only the first 16 has been published. The remaining 11 lectures can only be found in the first edition (1962-63). It is very rare but is there a (possible) way to read the content, provided that my...

Hi,I’m looking for online video lectures about principles of GPS but couldn’t find them. Can anybody recommend some?Senmeis

Is it because it is more rigorous than books like Halliday and Resnick? Or maybe you need to digest those books as a prerequisite for the feynman lectures? Or maybe people don't believe a regular person could digest the feynman lectures as a introductory level physics book? If someone is a...

I want to learn cosmolgy very much,Like from the begining,Proper distance comoving distance how can we measure them then friedmann equations etc. I know leonard susskind lectures but he is describing too general,I want more detail. Is there any other good video lectures...(I couldn't find) a...

Hello everyone. I am a laymen (with math knowledge) interested in learning about quantum mechanics. I came upon this video series from professor Benjamin Schumacher, which I believe is from 2008. Link...

I couldn't understand the physical meaning of this equation.Could anyone please tell me?(the last equation)

I am a high school student looking for some amazing lectures online to study classical mechanics for a regional qualifying camp for ipho.

Hi all! I'm a senior philosophy/economics undergrad and I'm recently finding myself very interested in physics. For several reasons, I'm not able to take physics courses in college, but I wanted to introduce myself to the "corpus" of the undergrad physics. I'm willing to invest time and have...

Hello I don't know is it right place to ask this question but does anyone know a writing program that allows to write Equations?

Why doesn't The Feynman Lectures consider the possibility of negative ##\alpha## when it says that ##e^{+2\alpha\rho}## is a rapidly increasing exponential (just below http://feynmanlectures.caltech.edu/III_19.html#mjx-eqn-EqIII1923) ?

Anyone knows when is the next Susskind lectures and how does one attend them? I am not talking about viewing the pre-recorded lectures on Youtube but I would like to attend the original classroom ones from which the youtube ones were recorded. I have not found any information on the Stanford...

Hello everyone, i am currently bedridden and bored out of my mind , thus i have started to watch all of the Walter Lewin lectures that were removed from MIT's OCW(on youtube). Right now I'm doing 8.01X, the lectures are truly fascinating however all of the course work comes from a textbook that...

I'm looking for an online American college for a bachelor's degree, with video lectures, and no group work. What are my options? I have difficulty with reading. This kind of a college would work best for me.

In the third book of Feymann's Lectures on Physics(section 1-8) he describes how "the Uncertainty Principle protects Quantum Mechanics." The experimental situation is a modified double slit experiment where the two slits are put on rollers in an attempt to detect which slit an electron passes...

I just had an idea that it would be good to go and attend a public engineering lecture (having discovered that they exist), as I want to do engineering at university eventually. Do you have to apply to go to these? If they are free, is it the case that they get fully booked by engineers? Have...

I took differential equation 2 last semester and the book we used wasn't so great at explaining a lot of things. I was wondering if anyone knew of a video lecture series that parallels my book (Differential Equations 4th Ed. by Blanchard, Devaney, and Hall). Specifically I am having trouble with...

Hello everyone. I'm studying Mechanical engineering but I'm at Foreign language preparation class. My area is Space and aircraft. I'm studying Aircraft Deisgn (Daniel P. Raymer) and I think I've to improve myself in physics area. I thought that Feynman lectures on physics can be good start. What...

Can anyone suggest good books and lectures in general physics that can still help in physics nowadays ? And i like to know best authors names in physics .

Hi For keeping with full disclosure - I hope to use this information to determine the need for an idea I've had that would make the lives of maths/physics students easier. I have just two questions I hope you can answer... What software do you use for taking notes during lectures and...

I know that the Millennium Edition of FLP is supposed to be the most up-to-date and corrected, however, I have read (in amazon) really less than ideal reviews on how glossy the pages are, how light the printed text are, and how the texts go inside the left margin making it very difficult to...

Hello guys. I've seen a lot of differing opinions on this site. I'm a middle schooler with a decent understanding of basic calculus, trig, and algebra. I want to learn physics, and am wondering if The Feynman Lectures supplemented with problems from Irodov and some of Walter Lewin's lectures...

Hello everyone, I don't get how the second-order derivative ##\partial^2 S/\partial x_i \partial x_j## of the phase S arrives here. If one performs a power series expansion of the Hamiltonian around ##\nabla S##, then I do get where the first term ##A## comes from, but then adding higher-order...

I am not quite taking Engineering Physics yet, but in preperation for a future degree I would like to jump in with both feet and take a journey through physics using the master's lectures. I know i will be in over my head with the problems, but i am extremely passionate about the subject...

Hi everyone, I'm a bit puzzled by the derivation of this formula, in particular since the definition of the "overbar" notation is a bit fuzzy (see Formula 6.4.1). Does anyone have a more formal definition of the correlation function in this setting (I know what a CF is, in general)? In this...

I have obtained Feynman's lectures, but I am not entirely sure if I have the math knowledge needed to understand it. I am a high school senior, but I have taken Calc 1-3, diffEq, Linear Algebra, and Real Analysis, and my math knowledge is not poor, but I am not entirely sure if this is enough...

Hi! I've bought book Feynman lectures, Feynman exercises and Physics Jay Orear. Is worthwhile to buy Landau and Lifshitz books? I'm beginner in physics. I'm not sure what to school textbooks. School programme is too easy for me. I need more accurate source to learn physics. Although in my school...

Hi, I don't get how one goes from 3.6.17 to 3.6.18 on Page 80 (Galilean invariance) regarding the zeroing of boost generator commutators. I do get that this is a special case of the Lorentz invariance (which I understand), but this particular step eludes me. Thanks for your help.

What is your daily schedule like? How many hours you spend on lectures, and how many hours you spend doing homework? How much do you study during weekends? Do you have "summer-break" like in high school, if so how long? Thank you.

I'm in the 11th grade and have little education of college level mathematics. I individually find myself studying one section of it but hardly have a grasp. I really want to read the Feynman Lectures to further my education of physics, but as I read over the pdf it looks like there is a lot of...

I have been going through feynmans lectures on probability and have a few questions that i can't answer ; in the part regarding fluctuations he introduces us to tree diagrams(pascals triangle ) and gives an example regarding the toss of a coin If we consider the no. Of tosses as n and no. Of...

In lecture 2,he states that when we prepare an electron and then apply a magnetic field,only 2 things can happen, no photon,or 1 photon. " if a photon is emitted,then its frequency corresponds to the amount of energy that would be radiated if the electron had been prepared in the <north-down>...

Does anyone know where I can find video lectures similar to in that they are from the 1950's?

What courses or physics topics would you like to see on the internet? I want to make a physics course series. I want to make videos and other resources (like animations, simulations apps, and games). I want it to be on topics that don't have a lot of videos and resources, and there are people...

I am looking for mathematics book required for Susskind's lectures on theoretical minimum?
