Heliocentrism Day

Last week's classes on Descartes went well (as usual). This week is a little more challenging ... Newton's Principia. The reading is tough but enlightening - Newton's preface, definitions, axioms (laws of motion), the first 13 propositions of Book III, and the General Scholium. Plenty here to keep us amused, with a combination of science and design argument (the Scholium). It will be interesting to see how it goes.

On a related note, Colin Purrington has some suggestions for celebrating Heliocentrism Day (remember, kids, it's JUST a THEORY) on February 17th. And there is cake involved! Ummmmm .... caaaaakkkke. The 17th is between the birthday of Galileo (15th) and Copernicus (19th).  And don't forget, Darwin Day is the 12th.

Greatest Physicists #1 - Isaac Newton The first and greatest physicist in my estimation is Isaac Newton, born in 1643. Lots of commenters absolutely correctly picked out Newton for the top spot, and had I picked anyone else (with the just barely plausible alternatives of Einstein or Galileo (and…
We're at that time of year where people publish lists of top stories of the year, but as many crazy people will be happy to remind you, this Friday marks the end of another calendrical period, in the Mayan calendar. So, I'm going to steal an idea from a college classmate on Facebook, who wrote:…
Discover is doing a "25 Greatest Science Books of All-Time" list. The great thing about stuff like this is it gets you thinking, talking, and exposes what your priorities are. There isn't a canonical list with a clear rank order. I mean, yeah, Principia is the bomb, but people can make a case for…
