Episode 46: Burning Twice as Bright with Alasdair Stuart
« on: May 12, 2014, 05:35:56 PM »
There's another reason fusion is so slow: fusing two protons gives you Helium-2, which is very unstable and usually decays back into two protons. Once in a while, it decays to deuterium (a proton and a neutron) instead. Once you have some deuterium built up, you can start fusing it with regular hydrogen to make Helium-3. That's stable, but Helium-4 is more energetically favorable, so the Helium-3 tends to go through more reactions and end up in that form. This is called the proton-proton chain reaction.

oh yeah man
we totally TOTALLY glossed over the nuclear physics.
that iceburg is huge and awesome but there was not time, so i decided to save it for another show.
Titanium Physicists has a pro-bee-analogy agenda. That's certainly no secret.

I THANK you for glossing over nuclear physics.  I can usually barely hold on to your show as it is.

But still.  I love it.  I am actually looking forward to playing it for my daughter.  I remember talking about it to my science teacher friend because she was lamenting "I wish I could show them more women in science that are cool like Neil deGrasse Tyson" and I was all "You should see the people that are on TiPhi!"
