(Click for larger view.) Well, I've already mentioned why today is such an important day in the history of human thought - One Hundred years of Certitude was the title of the post I used, in talking about the 100th Anniversary (today) of Einstein completing the final equations of General Relativity - and our celebration of it back last Friday went very well indeed. Today on NPR Adam Frank did an…
A free public lecture titled “Using General Relativity to Discover Planets” will begin at 11:00 a.m. on Saturday, February 21, in 100 Thomas Building on the Penn State University Park campus. The lecture is among the events in the annual Penn State Lectures on the Frontiers of Science. Read more about this lecture and the […]
