Well, the big reason early film is kind dangerous is that it was nitrocellulose, and so had plenty of nitro-groups just waiting to have a little fun...

McMaster-Carr is great, but SDP/SI has a larger offering of gears/pinions/belts etc. Amazon Supply is pretty useless, and Small parts was never really great either.

Isn't it possible to convince most antenna tuners to effectively match "into themself", and dissipate most of the power internally? I accidentally did that with a matching network I was trying to use to tune a weird inductive

If you really care about pie crusts, finding a good source of leaf lard is the #1 requirement. I tried a few pre-rendered brands, and it was all expensive, not particularly fresh, and tastes weird... Eventually I found a farmer who sells u

A non-trivial amount of what I work on is better diagnostics for C. auris. It's remarkably nasty stuff, especially the multi-drug resistant strains! One of those projects where I'm glad I'm on the analysis side of things, and

I'm putting my money on CryoEM solving all the relevant structural problems first. Plus, I like exotic electron optics and UHV much more than ML - at least you get some expensive paperweights when a turbopump grenades...

John C. Mauro does some really cool work, if you're interested in the underlying statistic mechanics of glass, and how to use computers to design better glass.

The shift away from each institution having a full-time glassblower doesn't mean that there isn't a lot of science being done in hand-blown glass. There are still lots of companies that can produce fancy glassware, and the Chinese

Almost none of the important stuff. I own most of the books on scientific glassblowing, and they're pretty much all outdated and primarily occupied with information about apparatus design. If you're interested in calculations for

Nope! Essentially all modern large thermonuclear devices are fission-fusion-fission devices, where the last fission stage (again, driven by fusion neutrons) produces the majority of the yield. You can omit that stage, by using a non-fissile

Well, GP didn't mean this, but most thermonuclear bombs derive a large amount of their yield from fission of a U238 "tamper" and "sparkplug", driving by neutrons from D-T fusion.

Some birds are thought to deliberately spread wildfires to flush prey out of grass ( https://news.nationalgeographic.com/2018/01/wildfires-birds-... ) - does this have anything to do with early human fire use? No id

Same here! Essentially everyone I follow on Instagram is an artist or skilled craftperson, with at most 1 degree of separation from someone I actually know. That means my feed is mainly people posting awesome projects they're working o

I've been doing a little wood turning lately, and have developed a deep love of exotic hardwoods. Such a guilty pleasure... Really good ebony is an amazing material to work with. Wood Database is a godsend for getting quality informati

Kill it some other way, and frequently test things that should be 'sterile'. I don't actually study (3) particularly, nor am I a biologist. As far as I understand, the "how" question is pretty well studied, and is b

This is kinda my space right now - remarkably hard-to-kill bacteria. Some fun stuff: 1) Ralstonia pickettii doesn't really need much to eat, and thus thrives in ultra-pure water systems. Like, you know, the ones used to make medical de

Nope! The tin-bath process is still dominant these days - the only people rolling glass are small-scale stained glass manufacturers. For lower volume (or higher tolerance materials), the overflow downdraw method and updraw methods are used,

Entirely automated - if it's glass, big, flat, and smooth, it was almost certainly made via the float glass process, or an equivalently automated continuous-flow system.

For cheap glass with big error bars on refractive index, dispersion, and defects, the process is entirely automated - think window glass or beer bottles. Quality control is still hard, and a lot gets recycled as cullet or discarded, but tha

Consumable graphite electrodes. (edit: also, there are plenty of materials that can deal with sustained molten steel content with acceptable service life.)

It's a text editor, not a lisp environment that edits text. I once had a decent amount of fun splicing it with Lua, before deciding that I don't actually care about text editors...

Even if they're not in string theory, they'll probably say something like that, or perhaps imply that he's actually an alien super-intelligence...

For the images to human interface, sure. But you can use pretty much anything small and fast enough to take pictures - neutrons, neutrinos, various ions, phonons... Now, taking photos is inherently photon/E&M based.

It was sunny today, and yesterday. It's been really weird, because I guess I had forgotten what sun was like...

Well, since it's electrostatics, dE/dt is tiny, and strictly, Maxwell's equations are overkill...
