Great weekend!

Wonderful warm, sunny weather on the weekend, so of course I got some cycling in. Saturday went up the Humber River valley, across the top of the city, and down the Don River. Sunday rode down to Oakville for brunch with marinav and ionelv. I'm still amazed with such perfect weather at this time of year.

Last week attended a great lecture at U of T, one of their regular public astronomy talks. This one was actually given by a particle physicist, and was on how modern cosmology can help out particle physics. Testing current theories requires experiments conducted at extremely high energies, so you need very expensive installations like the Large Hadron Collider. But string theories and the like require such vast energies to test we may never be able to do it. However, the very early state of the Universe (according to Big Bang theory) was in such a high energy state, and we are beginning to be able to test some of these theories by predicting what they would mean to the development of the Universe, and comparing these predictions to observations. Inflation theory has gotten a big boost from this work. it was a really good talk by a very animated speaker.
