Energized

Nicholas Payton came to town last Wednesday. For me, this means drop everything and go and hear him play. Two happy coincidences took place as well, contributing to making it a bit more special. The first was that my friend and colleague from UBC, Moshe Rozali (who sometimes comments here on the blog) was visiting to give a seminar that day. As I’ve been discovering (as a result of this blog more than anything else) we are very much in the same place when it comes to music, books and many things, and so it was just fantastic to be able to take him along. The second was that my friend of many years, cosmologist Marc Kamionkowski, got in touch just on the off-chance by email (I’d not seen him in many months) to ask if I knew if there was any good jazz coming to town! Marc and I have shared our love of Jazz for about 16 years now, going back to our days of meeting up in New York together at various Jazz clubs. So the three of us sat there and enjoyed the concert together. It was at the Jazz Bakery (to which you’ve possibly read me refer here before), and since I’ve not been there in a while, I was pleasantly surprised to see that they’ve replaced the plastic picnic chairs with some more comfortable padded ones. Quite an improvement.

Payton was joined by four excellent musicians, who were just great too: Russell […] Click to continue reading this post

There was a sweet, sweet moment during the afternoon Cosmology, Gravity, and Relativity session on Friday. (See here.) I don’t think I’ll be able to convey its full intensity to you, but I cannot let it go unmarked. The background comes from a personal place. In addition to my being, for many years, somewhat of a relative anomaly in being a black theoretical (high energy) physicist, there’s another component to that rare situation. My parentage is West Indian (or “Caribbean”, I might say, since in my experience the other term often does not register with many people from the USA), and until recently, I’ve not really known (m)any other such people in theoretical physics*. What struck me on Friday was a single syllable.

chanda prescod-weinsteinChanda Prescod-Weinstein (left), a graduate student at Waterloo/Perimeter, who has commented on this blog from time to time, and who I met for the first time on Thursday, was giving an excellent overview of her project to begin research on Doubly Special Relativity. Some of the motivating remarks involved simultaneously taking Newton’s constant, [tex]G[/tex] and Planck’s constant [tex]\hbar[/tex] to zero (the idea is that quantum gravity’s Planck length might remain finite in this limit, and thus remain in the physics as a new scale that breaks Lorentz invariance at […] Click to continue reading this post
