Leonard Susskind's lecture series on special relativity from 2012.
Here are presented some solved problems in special relativity.
How to go from the pair of equations:
E = γmc2 and 𝕡 = γm𝕧
[where 𝕡 and 𝕧 are vectors, and γ = 1/(1-v2/c2)]
to E2 = 𝕡2c2 + m2c4.
Theory and problems from A.P. French's book on special relativity.
Heuristic proof to the Galilean Transformation of Coordinates
de Sitter's argument that the speed of light is independent of the speed of its source.
A proof of the special relativistic Doppler effect
by use of a Minkowski diagram and the Lorentz transformation equations.
Faster-than-light speed problems.
Tachyons are hypothetical particles that can travel faster than light. But do
they appear to move backwards in time?
We use a spacetime diagram to answer
this question.
