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.
