From the Stone Tools project page...

>> If you have ever seen the fracture which results when a BB hits a glass window, you have seen the conchoidal fracture.

Wow the instructor sounds extra, but this would’ve been a great course to go through in a summer as a kid. It’d be fun to audit as an adult really.
mrKola•6mo ago
How is it that the new website is uglier than the old one?
quibono•6mo ago
I think chemistry is one of those subjects that should be the easiest to teach in a captivating way and yet most school/university level treatments tend to be quite dry. I imagine most of this is due to cost, safety and effort required but one can dream.
pstuart•6mo ago
A chemist once told me the two paths that bring people into chemistry are learning how to blow shit up and how to get high.

But yes, regardless of those two it should be easy to frame it as a magical adventure.

le-mark•6mo ago
I always thought breaking bad should have brought a lot of people into chemistry, but I’ve never seen stats that support that.
edwardbernays•6mo ago
I'm one.
devilbunny•6mo ago
I was a chemistry major. This is basically true.

There was one guy in my class that we all pegged as a recreational pharmacologist within the first week or two of freshman year. He's a good chemist; if he offered me something, I'd trust that it was both pure and exactly what he said it was.

eszed•6mo ago
My chemistry professor was one of those - though he was a professional unlicensed pharmacologist, if you take my meaning. He found (literal) religion, and went on to graduate school. I wish he'd told more stories; his classes were deadly dull.
devilbunny•6mo ago
Apparently he managed to tell you he had been a drug dealer, so at least one class wasn’t awful?
eszed•6mo ago
Heh. I only knew that because my uncle had gone to high school with him - not from anything he ever said! I gathered he let slip some things to chem majors (which I wasn't) in upper division classes, but not much. He was very religious, and I think pretty ashamed of his past.
riffraff•6mo ago
I heard from reputable sources that modern "little chemist" kits[0] have become quite boring, mostly for safety reasons (there's some nice single-use kits like Mel science but that's different).

Still, looks like you can still make a bunch of fun experiments in school? I've tried to engage my kids in some simple experiments (ph identification with cabbage, showing how bones can become brittle or rubbery depending on which components you remove, the classic soda&vinegar experiments etc).

University level treatment, dunno, seems like it should be fun but I had one chemistry class and balancing reductions is not that entertaining and that's most of it.

[0] I'm not sure of the actual English name, I mean those kits with a dozen things to combine, a becher, a Bunsen burner etc.

AngryData•6mo ago
Well that and both government and businesses don't make a lot of amateur chemistry that easy. Many chemicals have to either be bought second hand out of someone's bulk purchase for a licensed lab, extracted out of consumer products, or bought off shady amazon dealers at massive markups with uncertain purity standards. God forbid somebody finds you doing random experiments suspicious and calls the cops or something who are going to automatically assume you are being bad or dangerous or making meth.

Tried a few links and found them broken.

For example, Dunn's book on soap making. Nonetheless, Googled it:

The lead me to his Caveman Chemistry book on Amazon as well:

globalnode•6mo ago
The batteries page states "Current is defined as the rate at which electrons flow from anode to cathode" but is that true? Don't the electrons flow towards the anode?
globalnode•6mo ago
I've come back to report that after researching this, Electrons do flow from cathode to anode. Conventional current goes the other way if you're measuring ion (hole) flow in redox reactions for example. But I'm reasonably sure the electrons go the way I described.
