Awesome! I've taught chemistry this way!

Solubility basics: acidic substances dissolve better at higher pH and vice versa. Example: tea pigmentation, slightly acidic. Compare: normal tea steeping, steeping tea in water with lemon (hint: add lemon AFTER steeping next time!), steeping tea in water with a hint of cheap baking soda added (notice slight taste modification, does that feel familiar? Somebody might save pennies by using less tea to get the color and nothing else in the only drink available). Discuss.

Result: students leave outraged with their canteen, school admin, the government that made this happen.

Cheap difraction gratings though, indispensable

Yeah, friends with reds. Do all the hard work for them lazy asses to be backstabbed in the end.

Nah, they just do not trust me to donate if their material is good, best case scenario. I dont have enough time to read all the good stuff published by people who respect their audience to pay for this... Wait a minute, not even to them but to hardcore unethical publishing house?!

extractive to abundance

buy the book

Probably by rice, or koji. Or yeast!

This is so true! Tried "nice crossplatform WASM" multiple times - every time you need a system call, drawing single pixel, networking, or catching input - you just start debugging JS. If the logic is simple, whole code ends up being JS mess with small inclusions of Rust. Very unpleasant experience, even with all the modern frontend code generator tools.

I ended up deciding that making custom bindings instead (edit: mention uniffi here) and building frontend in native (Qt/Kotlin/Swift) ends up being simpler, more pleasant, and the end result is faster and prettier (and no wasm limitations). The downside is having to actually use XCode if you do want iOS app to work (which is quite simple but unpleasant and requires you to have Apple hardware or suffer a lot), but if not and you don't care for Apple worshipers - it's pure win.

Yes and no. There are grades, variations of acidity and oxidative state of medium through the year. It's heavy. It warps differently from everything else with temperature variation. Most of all, it is expensive.

I was also considering glass or clay overlapping tiles. Would be cool to cast huge ceramic panel, but it will crack, unless soil matrix holds it together. Shingles under sod might get roots growing through.

Another possible approach would be to allow leaks deliberately, then leave porous medium below the locking level with airflow access - so that any leaked water would be carried away with warmer air rising from habitation levels or even rhtough ventilation system or stove exhaust.

So much to study.

Didn't Finnish IQM do it already?

Those must be an event when a window pane on the floor above the place where the sensor resides cracked and fell and sliced the cable leading to detector. Took some time to fix things, probably just reallocated sensor ID to another station nearby. Old story.

A fun experiment in metro area would be not just measuring background, but actively filter air and measure what's left on filter. I too have a gamma scintillator crystal setup waiting on a shelf for a day when I have enough time to return to using it.

Or not well-designed. I'm sure someone like Mark Oehler could've figured something out. I don't have much sod here in central Finland, unfortunately, to try something, neither did he I suppose. I still think of how to cover the roof in living grass though, this is perfect roofing material IMHO once we figure out how to fix leakage without resorting to plastic sheets that my grass seems to tear like they are not even there.
