Thunderbird recently often breaks and stops checking new emails. Is that a Gmail issue or why can't it be reliably tested so it doesn't get broken again?
Only if the Windows Regional Settings List Separators happens to be "comma", which is not the case in most of Europe (even in regions that use the decimal point) so only CSV files with SEP=, as the first line work reliably with Excel.
Does anyone predict economy/population/... by simulating individual people based on real census information? Monte carlo simulation of major events (births, death, ...) based on known statistics based on age, economic background, location, education, profession, etc.? It seems there are not that many people that this would be computationally infeasible, and states and companies have plenty of data to feed into such systems. Is it not needed because other alternatives give better results, or is it already being done?
Feynman has an interesting story about critical mass:
> Los Alamos was going to make the bomb, but at Oak Ridge they were trying to separate the isotopes of uranium ... he saw them wheeling a tank carboy of water, green water - which is uranium nitrate solution. He says, “Uh, you're going to handle it like that when it's purified too? Is that what you're going to do?" They said, “Sure -- why not?" "Won't it explode?" he says. Huh! Explode?" ... he noticed certain boxes in big lots in a room, but he didn't notice a lot of boxes in another room on the other side of the same wall ... what you would have to do to fix this. It's rather easy. You put cadmium in solutions to absorb the neutrons in the water, and you separate the boxes so they are not too dense ...
