Comment Re:Home mitigation? (Score 2) 130

Horizontality is definitely an issue for bottle-fermenting beers. You'll mess up the yeasty sediment when turning it around.

In my experience, extreme cold is only a problem if you get down to freezing temperatures. I've blown up a few bottles by trying to cool them down faster in a freezer. What happens upon freezing is also great for the nucleation of gas bubbles; hence the cloudy appearance of homemade ice cubes, and the measurements of ancient CO2 levels from the bubbles in antarctic ice.

Comment Re:There is no vaccine for the worst diseases (Score 1) 1051

I agree with you on a general level, but I still think it's a nasty idea to use organic compounds of heavy metals as vaccine additives. You'd think there were saner alternatives by now.

Of course, the amounts are probably minuscule to other sources of heavy metal poisoning we have around. This IMHO is the biggest issue about non-scientific reactions -- hysterical focus on $some_single_chemical and ignoring all other dangers and matters of scale. In my scientific education, I think one key thing has been learning how to deal with uncertainty.

Case in point: getting hysterical about aluminium in deodorants, and switching to alternatives such as crystal deodorant... which are 100% alum. Of course, the real issue is probably with specific compounds such as aluminium chlorohydrate - no need to ban the entire aluminium industry for that. And don't even get me started on genetic modification which has been going around for about 10000 years...

You can implement a 3D game in Python, but its interpreter and memory management is going to make it much less efficient than the same game in C++.

IMHO that is a rather unfortunate example. I'm sure people have written 3D games in Python with not so bad results, because the 3D heavylifting is done on a GPU anyway (via PyOpenGL).
