Building on an earlier interest in space and spacecraft , I’d gotten very interested in physics, and was trying to read everything I could about it. There were several shelves of physics books at the local bookstore. The other books I’d read had all basically said “physics works like this”. The lambda hyperon.

These batteries pack a punch in terms of size and weight, crank up the heat with high internal temperatures, and don’t shy away from hefty price tags, making them a no-go for everyday folks. These devices generate electricity by capturing the energy from beta particles (electrons) emitted during the decay of nickel-63.

And for example the concept of “temperature” is there because exponential distributions familiar from statistical physics happen to be being used, but there’s no “physical” connection—at least so far as we know.) In this particular case, we can use known laws of physics to work it out.
