Looks nice, but I'm puzzled that for a scientific table the temperatures are given in Fahrenheit and Celsius instead of Kelvin. I understand, that it's easier for the non-scientific reader, but in this case it should be adjusted to the language as well. E.g. most non-english readers are probably not familiar with Fahrenheit.

It's always frustrating when you can't set the language of a website manually.

Genuinely curious what is the purpose of pointing out the size of the page in the title?

It's one of the things I appreciate about it - instant load of everything upfront. In a world of overbloated sites it's very small and does a lot with a little (I stumbled on it randomly on https://1mb.club a while back).

In mobile Safari 15.6 the page crashes when I open the menu on the right.

TIL Einsteinium has a melting point of 1133 K (860 °C)
