Epistemology Metaphysical determinism 20 May 201227 Aug 2012 There is a hypothesis called the Sapir-Whorf Thesis (also known as linguistic relativity) in language that one can only think what one’s language permits you to think, and indeed forces you to think. This idea that some conceptual scheme can determine how you think is widely held. It appears again… Read More
History Reminiscences of one who was there 12 Apr 2010 Early on, when I thought I would be an intellectual, a dilettante but still an intellectual, at the age of 17 or so, I read several books that I found at a second hand bookstore (my usual place of recreation). One was a little volume called Critique of Pure Tolerance,… Read More
Biology Paul Griffiths on Human Nature 6 Aug 200922 Jun 2018 Below the fold is a notice for a lecture by my friend and colleague Paul Griffiths that anyone in Sydney ought to go to. Sydney, Australia, not Sydney in any other country that seems to use all other countries’ placenames… Read More
I was educated at a Steiner school full of anthroposophical woo. Because the teachers were all homeopaths they had no idea how dangerous things were. I remember one teacher taking a teaspoon full of potassium cyanide out of a very rusty old tin and gleefully saying ‘we’ve enough here to kill off the whole school’. Oh, the fun we had. I learned a great dal about science there, often unsupervised, making my own equipment in a lab straight outta Hogwarts. Me and nitrogen tri-iodide… Happy days.
I never had a chemistry set but that didn’t stop me or my friends from building bombs ,flamethrowers and other weapons of mass destruction. When I was at boarding school one of my friends stripped the flesh off a dead rat to obtain the skeleton by dumping it in a bucket full of household bleach mixed with toilet cleaner. We put it out on the roof to avoid chocking on the chlorine fumes that poured off.
I think kids who grow up on farms still enjoy feeling that the whole world is their chemistry set. The things that can be done with literal tonnes of potato starch, or a bit of tar, or caustic soda. Of course, my cousin did blow the palm off his hand making some kind of improvised bomb… Possibly *actual* chemistry sets are the better option.
The universe will allow you to maim or kill yourself in all sorts of interesting and disgusting ways, if you really want to. The chemistry sets and homemade gunpowder of generations past are the least of them. Just look at the meth synthesis that some kids today attempt. Anhydrous ammonia? Pressurized reactions? And removing the lithium metal from those energizer batteries can get exiting.
The chemistry sets we had as kids, back in the 60’s, were pretty lame, but we still managed to make gunpowder with things we scrounged here and there. At least some drug stores in California would sell kids assorted chemicals. My one attempt at nitrogen tri-iodide wasn’t worth a damn, though. Anyone who waxes nostalgic about their teenage misadventures with chemistry would enjoy Oliver Sacks’ “Uncle Tungsten”, particularly the chapter “Stinks and Bangs.”
I once had a (chemically illiterate) Health and Safety officer ask me during a meeting at work: “do you have to use so many chemicals?”. I work in the pharmaceutical industry. As a synthetic chemist. In a chemistry lab. I replied that chemicals, and quite a few of them, were fairly necessary. To be fair to the poor bloke, he did mean “dangerous chemicals”, but that wasn’t what he said. That comment may have lived with him for a while…although I’m almost completely innocent of mentioning it. Almost. Louis
Brilliant pic! I gave up “practical chemistry” when I exploded myself (for the second time) with some HMTD. It’s a wonder I still have all my digits. The whole “terrorism” thing happened not long after that, so it’s probably a good job I quit when I did. Bloody terrorists spoiling all the fun…
