Learning ragtime feels like sitting at a piano for the very first time again. This is the hardest thing in the world I swear :’(
It looked like nonsense initially, but supersymmetry started making sense after I’d slepton it. #jokesnoonegets
The Sun is a Bit Shit
I don’t mean the “news”paper either, I mean the actual sun.
Fusion reactions in the Suns core give a power density of around 17W per cubic meter. The total output is only so large because the Sun itself is pretty huge.
In order to match the output of the Dungeness fission reactor we would need around 13,000,000 cubic meters of solar core-like reactions.
To put this in to perspective, the ITER fusion reactor is only 840 cubic meters. I think claiming that fusion experiments like ITER are “harnessing the power of the Sun” is a bit unfair. They’re making the sun look like a crying baby.
(I’m aware this whole comparison is ludicrous from a rigorous physics point of view, but it illustrates a point. The challenges we face with fusion are huge. We’re not trying to recreate conditions like in the core of the sun, we need to beat that. Significantly.)
Today I learnt about the ‘reciprocal lettuce’ in physics. Any lettuce structure with translational symmetry has a reciprocal lettuce, which also has translational symmetry and is the Fourier transform of the original structure.
Its very clever because if you find the reciprocal lettuce, easily obtained using diffraction and a bit of maths, you can work back and find the shape of the original lettuce.
Lettuce or lattice, something like that.
Spent the evening cooking up this bag of joy!
… It’s mint flavored sugar glass. I’m in denial BB is over >.<
