Backyard history: Southern California’s impact on astronomy

Silicon Valley has reshaped the earth, Hollywood has driven our perceptions of it, and not always for the better.  Less well known is the outsized role California has played in understanding our universe.   Mt. Wilson, Mt. Palomar, and their astronomers have had a Copernican impact on where we stand in the grand scheme of things.  The word ‘vision’ gets bandied about a lot these days but George Ellery Hale had it in spades.  Here’s how the two observatories that housed Hubble, Humason, ShapleyZwicky, Baade, Rubin, and Schmidt came to be.

The third video from Corning’s Museum of Glass shows that the path to science is not always smooth and that learning from mistakes is the norm.  The original 200 inch pyrex disk for the Palomar primary did not go according to plan and had to be recast.  The second attempt succeeded and even so, it took ten years of painstaking grinding and polishing at Caltech before it was ready for use.
