The Good Place (2016-2020)

Hey... what the fuck???

So I read the article, and this is super cool. Basically what happened is that they let a drop of butyl alcohol out from a syringe onto the surface of another liquid, and it just... hung out there? For a very significant amount of time, too. In the past, this type of "droplet levitation" has only lasted a few milliseconds max, but this droplet was staying levitated without any external forces applied for tens of minutes.

The reason this happens is because of Solutocapilllary convection, which as far as I can tell essentially boosts the surface tension of that one spot in the underlying liquid using vapor molecules, so that the butyl alcohol molecule can't sink in.

Also, the reason why I specified that the reason this was cool is because it was done without external forces is that APPARENTLY we've been able to levitate things using sound waves since like... the 1930s. And it makes sense that you can do that, in principle, but it still looks absolutely wild to see.

Strange question for all my biologists out there, no matter what your specialisation is.

Does anyone know any good books about biology? The more accurate, the better, they can be academic essays even, it’s all good.

I’m looking for a Christmas gift for my sister, who is absolutely in love with biology, and she studies it in uni too, it’s not only a hobby.

Unfortunately, having very very little knowledge in hard sciences, I cannot determine whether a book about biology is good or not, not by looking at people’s reviews and whatnot. And… I trust people on Tumblr more.

I’ve read a few reviews of some books, but I can’t decide. Please help a poor soft-sciences-lover in need!
