The Warren Astronomical Society meets monthly on the third Thursday in room 209 of Building B at Macomb Community College's South Campus. We do a bit of club business early on, then have a major presentation usually put together by one of our members.
David Yale Bailey, our resident Einstein #1, will be presenting a discussion of the various types of stellar explosions. Dave is a brilliant and iconoclastic mind who is able to convey his very thought-provoking ideas at a level any science-minded layman can understand, with the help of great conceptual diagrams and usually without resorting to the math.

“ Dave does a great presentation. Einstein at the chalkboard. And who can say "no" to explosions! OK, so it started with an example that isn't an explosion. But the idea that planetary nebulae - where a big fraction of the mass of a star goes out into space - isn't an explosion, well that's just as interesting. And, for the impatient, Dave presented a one liner, which he called poetry, which summarized the talk. Highly paraphrased: of the Messier list, only one is an explosion - conveniently M1 (the crab nebula). ”
“ Dave Bailey put on another tour de force of chalkboard visualizations and understandable but illuminating explanations of the really strange stuff that stars do. My only complaint is that he mostly covered stellar non-explosions - things that we sometimes think of as explosions that aren't. He promises a part II in the near future... ”

To quote Dave's poem about exploded star remnants on the Messier list:
"Messier 1
is the only one."
