K.V. Shajesh - retarded time
28 March and 4 April, 2019
K.V. Shajesh
Retarded Time
Shajesh kindly shares his notes with us. And here is a worksheet that illustrates some counter-intuitive features of retarded time, which he also used as a homework problem in his class.
Also, Punit sends a message:
Please read in the middle of the document about Pauli's comment on Einstein, american physicists, and american journalism.
Paul Halpern is a professor of physics at the University of the Sciences in Philadelphia. He is the author of Einstein’s Dice and Schrödinger’s Cat (2015) and The Quantum Labyrinth: How Richard Feynman and John Wheeler Revolutionized Time and Reality (2017).

M. Sayeh: time
Mohammad Sayeh
Time and the hazardous F-word
This will be a non-mathematics seminar on time, freedom, and related issues. I understand we need to review I. Kant, Bergson, etc. before the meeting.

Don Redmond
Evaluating the Riemann zeta function
Here are Don's notes that he kindly shares with us (+ his description):
There is some notes on a version of Euler's early attempts (Euler and the Basel Problem). Then there is the set of notes on the actual evaluation of zeta(2n). Finally, there are some notes on generating functions, which I am sending along because they include the details on some of the properties of Bernoulli numbers.
You need to download the files before opening to see the equations.
