Ahh, yes. I remember being taught this in astronomy class. Sweet memories

Same here (not that is was long ago, only last year) and I though it was just cool. Took a while to grasp the transition of the stars but I ove the jump with red giants stright off the main sequence and the temperature size effects. They must have been cleaver people.

Interesting ... you have been taught these things at school or at university? Unfortunately, my school offered nothing in this direction.

It was in my Alevel Physics Cosmology moudle that I was first taught it (though had met it in books) and then I poped allong and joined a astronomy course at uni which was cool, not that I do astronomy at uni. That's what I like about university!
