[Ironhorse]

If anything, I give Jackie credit for finishing the taping of the episode when she was apparently given the option of leaving to seek medical treatment instead. Seriously, what a stupid conspiracy theory.

Second time now: The triple crown winning horse is Justify. It's too important of a trivia nugget to let go uncorrected.

Was the clue correct when it said meteors burn up due to friction? The NASA web site implies this. But I assumed they burned up for the same reason rockets need heat shields. They compress the air in front of them, thus super-heating it. Not to disagree with NASA, but this web site agrees with that analysis. Can someone get Joon Pahk back in here to answer this?

Well, what do you think causes the heating from compression? Friction, my fine feathered Aptenodytes forsteri.

Unless I'm mistaken, friction is not the same as compression nor is it the reason compression causes heating. Friction is the force resisting the motion of a fluid (air) across the surface of a body (the meteorite). Heating from friction comes primarily along the sides of the meteorite as it passes through air. It also comes at the front of the meteorite from air that manages to slip around and slide up the sides. Heating from pressure involves the gas that can't get out of the way in time and slide up the sides to cause heat from friction. Instead, the gas compresses and that compression is directly proportional to the rise in temperature. It's that non-friction heat at the FRONT of the meteorite (relative to its motion of travel) that is the primary cause of the meteorite burning. The heat from friction is, as I understand it, secondary.

To sufficient accuracy for the vast majority of analyses, this heating is indeed from compression. This is straight out of 3rd year undergraduate compressible flow theory, and is an entirely inviscid-flow result - i.e., no viscosity, therefore, no friction.

Justify my love?

I just binge watched Jackie’s run this morning. What a star! Now I can go read all the articles and blog posts, then whisper to my cats if I think she was faking the illness

No good guess on Mozart’s final work, but ‘the year he died’ should have been enough
