What I mean is, what if there were a specific derivative to our own life?...

Season 5 of The Big Bang Theory has picked up, right as they reached the 100th episode of the series. The three latest episodes have had some of the funniest moments of the whole series, and seems to be setting the stage for the rest of the season to play out in a way that I'm really looking forward to. You can check out the coverage of the science that shows up, as well as some notable quotes from each episode, in the individual episode reviews from this month:...Read Full Post

De Sitter spacetime is the maximally symmetric solution of the field equations of General Relativity when a positive cosmological constant is present. It has been studied extensively for many decades from many viewpoints: as a classical geometry, as a possessor of a large symmetry group, as a background geometry which may or may not be [...]
