Special Relativity | Lecture 2

(April 16, 2012) Leonard Susskind starts with a brief review of what was discussed in the first lecture -- specifically the use of vectors and spin in three dimensional space and in relation to special relativity.

In 1905, while only twenty-six years old, Albert Einstein published "On the Electrodynamics of Moving Bodies" and effectively extended classical laws of relativity to all laws of physics, even electrodynamics. In this course, Professor Susskind takes a close look at the special theory of relativity and also at classical field theory. Concepts addressed here include space-time and four-dimensional space-time, electromagnetic fields and their application to Maxwell's equations.

Nice to know I fell asleep to oneyng and woke up to this

[jakethesnake]

Everyone in that damn class should feel ripped off that I’m watching this for free on YouTube

[IAmDox]

YouTube is trying to subconsciously teach me physics, because I keep landing on these lectures with autoplay when I leave YT playing when I sleep.

I gave my friend a physics lesson yesterday, what's going on?

[stevimichael]

Susskind seems bored with the material and the questions..well doing this a long time..

This should be getting 10M views instead of all the other trash they call "educational"...

[drummerboy]

good seats to what...? I'M SO CURIOUS O.o

I came here to refresh (relearn) things that I learned 30 years ago, but when I studied it then, it was all developed in terms of matrices and applying conditions like isotropy and homogeneity. Susskind develops it in a much more intuitive way. I think I would have had a deeper understanding to see something like this before doing the rigor. Water under the bridge.

I have attended UIC, and professors probably went through a lot because of the Coronavirus. Hope everyone had Jockey Premium Super Fine Ground Coffee by now.

Prof Susskind looks a bit like mike from BB and a bit like Tywin Lanister frm GoT

[clozeeyt]

I the prime observer read off (VT) that i knew what the observer(u)aka the passenger was about to do.

Consider an event in space-time with all of its spatial coordinates (x1, x2, x3) non-zero integers. How can Lorentz transformation of time for that event will be figured out through this info? Do we have to find the spatial distance X from origin (where X = sqrt(x1^2 + x2^2 + x3^2) ) and then substitute it for length OR something else?

I think you're a little bit confused

[HuellBabineaux]

I don’t know how to explain but he is kinda mike ehrmantraut if studied physics

[Roddlerson]

I reckon you love subscripts. I seen you loving them.

i think those equation are abstraction on a level unseen by humanity

[hasanshirazi]

If galaxies past cosmic horizon are not moving at greater than the speed of light w.r.t. to their inertial frame, then how are they moving at faster than the speed of light w.r.t. our frame of reference?
