点评:To everyone interested in the origin of the universe (and that surely includes almost all of us), the Mount Wilson Observatory - high in the San Gabriel mountains above LA - is a place of pilgrimage. It’s not just the amazing views and the natural mountain setting; it’s also the place where Edwin Hubble worked establishing not only the existence of galaxies outside the Milky Way but also the expansion of the universe, work that led to the theory of the Big Bang. So, I was pleased to be taken there during a visit to LA, even if the trip involved ascending for some way along Highway 2 and then branching out along the road to the observatory itself. When we got there, we learned about Hubble and his groundbreaking work, of course, but also about the important continuing research on solar activity (including sunspots) and the CHARA array that carefully coordinates data from six telescopes thereby providing remarkable detail - as small 200 micro-arcseconds, according to the information. Awe-inspiring stuff. And then there are the views...
