I could just be flattering myself, but I honestly think the "Quantum mechanics" in the section description was a result of me and a few others often getting into arguments/discussions over weird theoretical physics stuff in the really early days of the forum. We had more than a few sciency people, and not a lot to talk about. Now that it's grown, anything sciency is quickly overshadowed by more accessible topics. But I feel your pain; I want my freaky science back
While I did understand a lot of what you said (or at least, more than most people would), a lot of the equations were over my head.
Although, in response to your video: you said you didn't know if there was a way for elements heavier than hydrogen to form naturally? The vast majority of them (up until #92) form from extremely high energy fusion in the cores of stars (the more massive the star, the higher the energy in the core, and the heavier elements it can fuse), supernovae, and other such high-energy things. Elements up to #99 can be found in nature, but it's really hard because they all have short half-lives (on a geological time scale), and I'm not sure how they are formed.
Elements over #100 are all synthetic, as far as we know. Most have a half-life of less than a day, too, so it's really hard to study them.
