I respect professors who go read the original work of scientists and turn it into an amusing lecture. I just enjoyed every second of this video. Thank you very much Sir

Countless times i have been studying length contraction This is the first clear explanation about the meaning of measurement "No contradiction"

Many thanks to Stanford and Prof. Susskind. I've watched a few series, and I really love the way he explains things, in a very logical and simple way. Helped me understand many things that apparently were not as clear as they should have been to me!

This is a God sent seriously. Been reading through three books today and a lecture discussing the same topics u talked about in the first 11 minutes. Yours made so much sense - I really appreciate all the chronological science history as you teach. So many leave the little things out.

Wondering why these kind of lectures help me sleep so well when I came to the ugly realization that it's most likely because it brings me back to a simpler time of... sleeping in class.

this video is amazing. Truly easy and fundamental. Thank you so much for the upload. Much appreciated. And professor Susskind, I must say that I am a big fan!

This first lecture really blew my mind the first time i saw. This isn't gold; it's platinum! Susskind continues to inspire my own teaching, and of course, my study of physics :)

I cannot think of physics without prof Suskind. It is amazing to see a genius like him teach being humble to the core despite his genius! He is exemplary in every way! God bless him and wish he gets his Nobel Prize which he richly deserves very soon!

Thank you Dr Susskind. Posting this comment right at the top here as a high school physics teacher. The first 4 lectures are the perfect introduction for my students into special relativity, taught the way it was meant to be taught--straight from Einstein's paper, explained in common language. I show these first 4 videos every year at the end of our units on classical mechanics as a follow-up. The kids love them, and love Dr Susskind. Thank you thank you! Follow up--thank you for our list of Susskind-isms--"time is time is time is time", "derove", and who could forget poor Seymore, out there on his world line all alone waiting for a light ray.

What is he explaining

These special relativity lectures, and the whole series of physics courses of which they are a part, are excellent. Susskind's explanations are very thorough. Thanks to them, I understand the material better than I did when I was a physics major 40 years ago. He does occasionally slip up with minus signs, but this gives you the opportunity to redo the derivation and figure out where the slip occurred, where doing this definitely helps you learn the material better.

Rather, the idea is based on an error in logic: _"The 2 photons will have been sent simultaneously only if they arrive simultaneously at the midpoint, therefore if they arrive simultaneously at the midpoint then they will have been sent simultaneously."_ That is, "if p then q, therefore if q then p". This is a formal fallacy in propositional logic, called "affirming the consequent". The truth of the matter is that the photon at B is fired later than the photon at the origin, and this because it has to travel a shorter distance in order to arrive at A at the same time as the photon from the origin arrives at A. And so we see from the chart that B is at t>0. So there is only 1 time scale, t, for you can't have a moving system of clocks and have those clocks not tick. Clocks tick. That's what they do. So t' is only 0 along the x axis, which is where (and when) the first photon is fired, for the first photon is fired at the origin and at the origin t' is on the x axis. After that, t' is greater than 0, because its clocks are ticking. And so t' is synonymous with t, and therefore superfluous: we only need t. The problem is that the issue is not really a physics issue, but a logic issue. Physicists are not necessarily good at logic. Logic is a different skill. If you wish to see how SRT is errant at its very first derivational step, just search "Nullification of Relativity Theory via the Sufficiency of the Galilean Velocity Transformation", click on the viXra link, and then click on v2 of the PDF.

It's actually amazing that working through deriving the way space and time relate to each other under coordinate transformations is extraordinarily clear and makes total sense, as long as the only special assumption is that the speed of light must remained fixed. Also, I've always wondered why Einstein would make that assumption in the first place, but his mention of thinking about Maxwell's Equations also makes total sense. You shouldn't be able to make the electromagnetic field vanish by moving fast enough.

This knowledge is so valuable. It was so difficult to find a lecture that used this simple method of plotting these quantities on a Cartesian plane. That makes it so much easier to see how all these quantities relate. Sure, it is a longer video than you find on some of the pop science channels that are popular. But an investment of a hour is more than worth it. The attempts to gloss over this step on popular videos might make the video get more plays and likes. But it shorts the viewer on the necessary steps.

All flowed over my head but I am glad that I watched this anyway

A very nice series of introductory lectures pervaded of Richard Feynman's spirit.

At 1:27:25, it shows t is dilated when t'=1 from the view point of moving frame, but t' is contracted from the view point of the rest frame. For example t=1, x=1 are both contraceted in the moving frame to sqrt(1-v^2). Time and space are both contracted in the moving frame. Contraction of time is slowing down of the clock, i.e. dilation of time.

Can anyone tell me in which of his lectures he teaches spacetime diagrams?

Give this man a nobel prize for teaching

This is good stuff, I hope that I'll be able to understand more of it as I go on :)

@vikram T That's a good question. But the galaxies are not being separated by their movement. It's space itself that is expanding. Their distance is increasing exponentially, but their velocity isn't.

Esteemed professor Yes Galileo did write about Wonderful pages about a moving ship Train did not exist yet at his age Thanks

Confusion around 24:00 It says: "what about me who is moving? ...when I get to this point over here, let's say that it just happens to be the point when you emit your simultaneous light rays..." Is the word "point" being used here in two different meanings, one as a position x and another as a moment in t? If the second is indeed t, then according to which clock was it defined?

@paulcurry8383

The word point is describing a (t’, x’) coordinate in the (t’,x’) plane. Since the person in the middle telling the two people whether they are in sync is moving at the same velocity as the person on the right (the prime frame)

“If Einstein is right”… that statement alone transforms this into a philosophy class alas to run with it is mind-boggling.

Time stops at velocity=c. He covers this toward the end of the lecture while discussing time-like and space-like intervals. Watch at around 1:45:00.

What he talking about

What an interesting looss way to work out these calculations that are actuallz so simple.

1/3 It may be for we first describe a 3D space and then we had time in it. So we try to describe the motion in one or more dimensions in a way we are more comfortable in visualising it. The following is an extract from wikipedia:

Is there a recommended textbook to go with these lectures?

Just reading his new book “Special Relativity and Classic Field Theory”

There are different ways to think about this problem. And the scenario used @ 33:10 to explain the dynamics makes it simpler.

Clocks and lengths do not actually change in YOUR frame or reference when you are moving. They only appear to in somebody's else frame of reference that is stationary relative to yours. And Visa a Versa..

Around the 30.30 minute mark, you indicated that a stationary mover would move along the x-axis but in reality, the stationary observer would stay at x=0 but move up the time axis. The time changes for the stationary observer but not the spatial extent. Or am I missing something.

He is very clear in his explanation. there is no need of any subtitile

very clear, good lecture.

No book has shown that why (ct)^2 - (X^i)^2 is the length element. They just say it is because of invariant purpose.

It's a statement of the invariance of the speed of light. The fact that the expression you wrote is the same in any two frames is a statement that the speed of light c is the same in those two frames.

Its would fine if it in these lectura to have some translations, especially into spanish. Thanks a lot.

Question, around 51:25 when he shows that the two scaling functions (Lorentz factor) f(v) and g(v) must be equal for the space and time components by saying that when x = ct, x' = ct', doesn't this only show that f(c) = g(c)? x' = (x - vt)•f(v) and t' = (t - vx)•g(v), setting x=t, x'=t', x' = x(1 - v)•f(v) = x(1 - v)•g(v) = t' (1 - v)•f(v) = (1 - v)•g(v) only for the initial assumption v = c. I could construct a similar function (4 - v)•2v = (4 - v)•v² which is only true for v = 2. Also, is the assumption the gamma is only a function of the magnitude of the velocity, and not the vector the assumption that the universe is isotropic?

So this is why I'll be going to school on 4 hours of sleep.

50:00 Presumably, the light ray is emitted from the origin when the origins of both frames coincide. Then x=t and x' = t' for the ray.

At 1:15:50, we found using Lorentz transformation that the length of a stationary meter scale measured from a moving reference frame is contracted by a factor of sqrt(1-v^2). But in the space-time plot the length of meter scale from x'=0 to x'=1 along the x' axis appears to be greater than 1 (from basic geometry). What am I missing here?

Ok, so he spoke about it later in the lecture.

Cameraperson: if the prof writes something based on other info on the board, make sure that other info is also in frame.

If anyone is looking for an easier explanation of special relativity's concepts, I highly recommend VSauce's "Would Headlights Work at the Speed of Light?" video. He has a lot of graphical and animated explanations there, while these lectures involve more mathematical proofs and calculations. I found learning the concepts first and coming back here for the math much easier, especially since I'm doing this before quantum mechanics (standard curriculum teaches QM first).

+RunItsTheCat First notice that their is an Eter. Thats fact! So no we debunk this shit by the sionist fraud St Einstein. Dayton Miller redid the Michaelsson experiments but 10000 more carefully and did se interaction. To day we see it for Bifeldt Brown , Casmir effect and 100 other things. The EM wave does spread out transversal into Eter with C but the dielectric vawe propagates faster ( Tesla did calculate) . The magnetic propagation vawe never determined at all ! But true they probably are longitudal and thats for study. So no go and study the artifact,, co-rotating magnet and faraday disk for example. If we check two conductors parallell with same vector currents. If you are the "electron" propagating in one conductor and your buddie is in the other conductor moves parallell to you with same speed, do you se any relative movement? No HELL no. You are moving at constant speed and so is your friend. BUT YOU VILL notice that your conductor moves to your friends conductor and the opposite !!!!!!!!! The relativists explains this with circular argument introducing their fraud theory. If we take in an eter you got your relativity but the relativists does not like eter but today they call it dark energi and a lot of other crap. REad Bjerknes book St Einstein pdf at youtube to get why the banksters gaved us this fraud. E = MC2 was known by Maxwell before Einstein was dry behind the ears. The space is working by electricity and birkeland, Tesla and the real physisits did all this finnished together with the guru and legend Hannes Alfvén. The establishment does not wont us to know as they want us to live dumbed down.
