Abhay Ashtekar on Gödel Universes, Buddha's Poison Arrow, Time Travel, and Loop Quantum Cosmology
Abhay Ashtekar - from Wikipedia - https://en.wikipedia.org/wiki/Abhay_Ashtekar
Abhay Vasant Ashtekar (born 5 July 1949) is an Indian theoretical physicist. He is the Eberly Professor of Physics and the Director of the Institute for Gravitational Physics and Geometry at Pennsylvania State University. As the creator of Ashtekar variables, he is one of the founders of loop quantum gravity and its subfield loop quantum cosmology. He has also written a number of descriptions of loop quantum gravity that are accessible to non-physicists. In 1999, Ashtekar and his colleagues were able to calculate the entropy for a black hole, matching a legendary 1974 prediction by Hawking. Oxford mathematical physicist Roger Penrose has described Ashtekar's approach to quantum gravity as "The most important of all the attempts at 'quantizing' general relativity." Ashtekar was elected as Member to National Academy of Sciences in May 2016.
Abhay Ashtekar is an atheist, though he enjoys reading on Indian and other eastern philosophy, namely the Tao and the Zen traditions. Furthermore, he believes to be inspired from the Bhagawat Gita as regards his attitude towards work.

Salman Rushdie: The idea of the sacred is...
“The idea of the sacred is quite simply one of the most conservative notions in any culture, because it seeks to turn other ideas - uncertainty, progress, change - into crimes.”
Salman Rushdie, “Is nothing sacred?”, Penguin (Non-Classics),1990

Memories from ONU
Until not long ago, these cannons were placed in front of the Meyer Hall of Science.
At some moment in the early 2000s the Physics Dpt had a plenary talk by Gerardus 't Hooft, Dutch Nobel Prize winner. As I was interested by some entanglement problems, I tried to present our distinguished speaker some of my thoughts. I was talking to him along the road from the dining area to Meyer, and as we passed the cannons, he stopped for a while, looked at the cannons and told me he felt that the presence of such symbols in front of a university building was not a nice combination, since it reflects hostility. Honestly I did not pay much attention to the cannons, but I agreed with him.
Recently they were moved near a lake on campus (pictured here).

Desolation Row
At the same time atemporal and in minute, humorous-to-damn-serious historical detail... the fact that this masterpiece comes from somebody who won Nobel Prize for Literature, makes perfect sense.
