The eggs are OK (could have been more equally spaced though). I mostly like the multi-colored alphabet letters near the bottom of the refrigerator. The longer I looked at them the more I was reminded of globular clusters, particle collisions and art.O B A F G K M
. This is the Harvard Spectral Classification System for the stars. Each letter corresponds to a certain type of spectrum, and therefore color, of a star. The letters also correspond roughly to the temperatures, with O, the bluest, being the hottest. Why aren't the letters in alphabetical order? Well, they started out in order, according to the strength of the Balmer lines in the spectra, but then some of the letters turned out to be equivalent, so they dropped those. Then the order was rearranged according to temperature. Rather than rename the spectral types, they simply placed them in the correct order, and so we have OBAFGKM. To remember this order, we like to invent mnemonics. The most common one is:
. Oh, Be A Fine Girl, Kiss Me
. There are three more types of stars, that are mixed in with the M giants. These are R, N, and S. So, adding these letters to the mnemonic we can have:
. "Oh, Be A Fine Girl, Kiss Me Right Now...Smack!"
. Here's a list of some other mnemonics I have collected. If you come up with any, with or without the RNS, please send it in. I'll give you credit for it.
. Note: Recently two more types of stars have been added to the sequence, cooler even than the M stars (that is, less hot than M stars). These have been named L and T stars. I still don't have many mnemonics for this sequence, so if you know any more, please send them in!

Cool ---- thanks! New background.

I still think it was strange that Phil chose to dig in his heels and not correct
the demonstrable error. Here are the links again:

I sent him an email some time ago and the reply was to the effect that ‘normal people don’t view meteor showers with telescopes’.
Wha-? normal? I guess abnormal people do, LOL
