Einstein's General Theory of Relativity is our best guess at the nature of space and time and it is turning 100 years old today. (To be precise, this is the 100th anniversary of its publication)

The European Space Agency's Faint Object Camera on board NASA's Hubble Space Telescope has provided astronomers with the most detailed image ever taken of the gravitational lens G2237 + 0305 — sometimes referred to as the Einstein Cross. The photograph shows four images of a very distant quasar which has been multiple-imaged by a relatively nearby galaxy acting as a gravitational lens. The angular separation between the upper and lower images is 1.6 arcseconds.

1. Will watch with great interest.

BTW, he did not develop relativity on his own. Special relativity had underpinnings from Lorentz, and general relativity from mathematicians like Hilbert. However, what Einstein did in 1905 and 1915 was to put together a framework that revolutionized how we see the universe. That was what was important.

Yup! The universe really does work this way.

2. How about Poincaré and Riemann, respectively? n/t

4. Let us also not forget Emmy Noether

https://en.m.wikipedia.org/wiki/Emmy_Noether

Emmy Noether (German: [ˈnøːtɐ]; official name Amalie Emmy Noether;[1] 23 March 1882 – 14 April 1935) was a German Jewish mathematician known for her landmark contributions to abstract algebra and theoretical physics. She was described by Pavel Alexandrov, Albert Einstein, Jean Dieudonné, Hermann Weyl, and Norbert Wiener as the most important woman in the history of mathematics.[2][3] As one of the leading mathematicians of her time, she developed the theories of rings, fields, and algebras. In physics, Noether's theorem explains the connection between symmetry and conservation laws.[4]

6. True...

Here is a potentially interesting presentation on Noether's Life and Work:

5. Yup! Them, too.

Shoulders of giants.

7. So...are you up for a relevant but bad mathematics joke? If not, don't read below...

Did you know that differential geometers are generally very weight/health conscious?

8. Oh boy.

11. They mostly use local coordinates... n/t

3. Not a long time, relatively speaking...

10. You have a warped sense of humor.

9. a fun video helpful in visualizing space-time warping.

but remember, this is just a 2D analogy..

12. Two hours of Einstein tonight on PBS Nova.

Beginning at 9:00 PM EST.

Tune in!
