“Jupiter instead cooled down below the threshold for fusion, but it maintained enough heat and mass and pressure to cram atoms very close together, to the point they stop behaving like the atoms we recognize on earth. Inside Jupiter, they enter a limbo of possibility between chemical and nuclear reactions, where planet-sized diamonds and oily hydrogen metal seem plausible.”

“B2FH traces these various fusion reactions and explains the recipe for producing everything up to iron: it’s nothing less than evolution for elements.”

“Scarily, cadmium is not even the worst poison among the elements. It sits above mercury, a neurotoxin. And to the right of mercury sit the most horrific mug shots on the periodic table—thallium, lead, and polonium—the nucleus of poisoner’s corridor.”
