intro to cosmology part 1

[rccaulfield]

I can't believe you started with copernicus? Surely a mention of the science in the greek islands and specifiaclly Erathosthenes who was the first theorist who came up with the heliocentric model- 250bc. Do you do public lectures near Dublin?

[Piscivorus]

Is there any way to learn this math without attending a college or university?
