I’ve never found a good link, and I’m not certain that I know best, but I can try to explain it to you.
First: an understanding of the Pauli exclusion principle. Often people ask “Why can’t there be 3 electrons in that orbital, there’s plenty of space?” The thing is that the electrons are completely¹ defined by just 4 numbers: spin (±½), shell (positive integer), subshell (integer from 0 to shell-1) and magnetic (integer form -subshell to +subshell). Why there can’t be more than 2 electrons in the 1st shell is that you can chose spin from (±½), shell is 1, subshell has to be 0, magnetic has to be 0. Its like asking “Why can’t there be 3 integers between 0 and 3, there’s plenty of space?” and the answer is that whatever integer you come up with will be one of the 2 already known (1, 2).
Similarly, as I understand it, the fundamental laws of physics don’t distinguish between “things” closer than 1 Planck length apart. That doesn’t necessarily mean that the universe operates on a 1 Planck length grid, just that any two “things” separated by less than a Planck length are indistinguishable from one new “thing” with different properties.
I’m fairly confident in the PEP description, the Planck length one I’m less 100% sure about, but its how I understand it at least.
¹assuming a universe comprised of only a single hydrogen atom, otherwise the states of everything else in the universe can perterb the state functions and things can get messy, but usually not enough to merge shells.

I’m one of the very rare people that have the gene that makes cilantro taste like soap, but likes it. I blame the soap flavoured gum I had as a kid here in Canada.
So maybe save a little soaplantro for those that want it ;)

Thank you. Clear, easily understood explanations of questions I always wondered. 👍🏼

Whenever I see this image I always wonder 2 things:
- What makes hemoglobin more efficient?
- Why do we even need these fancy molecules to transport oxygen? Can’t we produce some kind of biological ampule that holds some pure O2 for consumption by the various processes that need it? We have dedicated organelle structures for similar tasks (i.e. mitochondria)

Apparently it’s not even really all that stable, so that whole container would rapidly decompose into probably carbon dioxide (CO2) and a bunch of pure carbon (think charcoal). At least that’s my hunch. There is a Wikipedia article on the stuff, but it’s pretty short, since it’s a pretty unusual chemical (en.m.wikipedia.org/wiki/Dicarbon_monoxide).
CO2 is of course extremely common. I’d love to see what a chemist can describe about a bottle of C2O though!
- Comment on DNS over Wikipedia 9 months ago:
If you read the readme, this looks like it’s specifically for when you don’t know the correct tld or spelling of the site you’re looking for. Google searches often censor sites of borderline legality, but they’ll usually still have Wikipedia articles with accurate links.
This specifically only redirects .idk domains as a search helper. Could it possibly work better as a browser extension? Maybe. :)
