H-R

OK, the Hertzsprung-Russel diagram.  Science geeks know it: it describes the Main Sequence of stellar evolution, from protoclouds to yellow dwarfs (Sol) to supergiants to black holes.

Behold the H-R diagram of Astronomers!



We loves it. Thank you, Bad Astronomer!

The chart certainly wasn't put together by somebody that has lived within the reception area of the BBC television service. Where's Patrick Moore (or more correctly Sir Patrick Alfred Caldwell-Moore ... wiki entry here) who has presented the monthly "Sky at Night" program pm the BBC since 1957.

Close to 50,000 returns on a Google search for: "Patrick Moore" astronomer

Kind of scarey how many names I recognize.

(I'm on Dr. Porco's e-mail list. :)

But, they forgot Jack Horkheimer! ;)

It may be sour grapes, but Dr. Kaku always comes off as a lightweight to me. I find his ideas on futurism full of holes.

But, it may be that I'm just jealous of someone who gets to talk about the future on the Science Channel.

What sort of holes? ;-)

Re: (side note)
Here's the cop out:
It's been at least a couple months since I've seen him appear on a program, so I really can't remember details.

But, it did seem to me that he had a number of ideas that I rejected based on the thought that either people wouldn't want to do what he was suggesting, or there were more practical ways of doing what he wanted done.

Also, his definition of "practical", and "usable" seem out of place, when he's talking about using a time machine that would require more power than exists en the entire universe.

On a more positive note, I think the bad astronomy cartoon is hilarious. I haven't had a chance to indulge the Astronomy-Cosmology side of my personality, which I can really only let loose when Barb appears in the comic.

Meanwhile, I'm dismayed to recognize only Sagan and Hawking. ("Brian Cox" rings a bell only in acting.)

They show up quite a bit in cosmology programs aired on The Science Channel.

haha! This is gold!
Shows how much politics and social posturing goes on in a scientific community.
