I always think the phrase free radical describes I don't know people in San Francisco in the nineteen seventies, you know? matched

Yes, matched

As I've mentioned before on this um on this podcast a number of times, chemistry can my chemistry knowledge is out is pretty limited, right? matched

Like maths and physics, I'm all there. matched

Biology, I can I can make my way around. matched

Chemistry, it's is ropey at best. matched

Um But I remember in chemistry lessons there was this this talk about the states of the electron, right? matched

That it's like you have these shells. matched

Which I think is actually a an incorrect model. matched

That the that the electrons are at different levels, uh, energy levels, some farther and some closer in towards the the nucleus of the atom. matched

And when the electrons move between those states, move between those energy levels, that's when they start emitting certain colours of light. matched

So this is what I was thinking as you were talking. matched

Because actually, when you try and come up with a definition for what life is, consumption is a big part of it. matched

Being able to sort of uh self sustain is another part of it. matched
