Past 2019 Meetings


May 26th: GR#3 Scott – Tensor Math II


May 12th: GR#2 Tensor Math I

Attending: Eduard, John, Jonathan, Mary Ann, Mike, Scott, Stefan
References: (1) Collier chapter 5, (2) The big picture, (3) May 12th notes


April 28th: GR#1 Scott covered chapter 4 of Collier

Attending: Eduard, Mike, Scott, Stefan, Tina
Chapter four is fairly brief. If you didn’t make it today please take a look at it.


April 21st: Easter / No Meeting
Note that we’re changing to “even weeks” now!


April 7th: First look at Tensors

Attending: Eduard, Jonathan, John, Matt, Mike, Scott, Stefan, Tina
References: (1) Implicit Summation (2) First look at Tensors


March 24th: SR#6 Four Vectors

Attending: Eduard, Jonathan, John, Mary Ann, Matt, Mike, Stefan, Tina
Continuing “four-vectors” …
For anyone who missed last time or who wants something else that has a bit more detail than the book, this lecture is pretty good.


March 10th: SR#5 Four Vectors

Attending: Jonathan, John, Matt, Mike, Stefan, Tina

We derived the formula for addition of velocities and started talking about “four vectors” which are special relativity’s analog to things like position, velocity, momentum, and so on. We covered position and velocity.


February 24th: SR#4 The Relativistic Snake

Attending: Eduard, Jonathan, John, Mary Ann, Matt, Mike, Scott, Stefan, Tina

Tina presented the “relativistic snake” problem as described in John Taylor’s Classical Mechanics book.
We also spent some more time on the “horizontal light clock” that John brought up last time we met. This has turned out to be a very good example from various perspectives.
Here are some diagrams that might come in handy:

February 10th: SR#3 The Lorentz Transformation

Attending: Eduard, John, Mary Ann, Matt, Mike, Stefan
– The transforms
– Spacetime Diagrams
– Relativity of simultaneity
– John brought up an interesting scenario with a horizontal light clock.


January 27th: SR#2 Tina did Time Dilation and Length Contraction

Attending: Eduard, John, Mary Ann, Matt, Mike, Scott, Stefan, Tina
The group also worked several of these problems


January 13th: SR#1 Introduction

Attending: Eduard, John, Mary Ann, Mike, Scott, Stefan
– Notions of relativity before Einstein
– Postulates of Special Relativity / preview of their consequences.
– We used These Notes
