The obvious one is buying drugs. I don't feel like arguing the morality of doing that but anonymous money is definitely useful for that.

Isn't "I" considered poor form? I was taught to always write in passive but "we" is kind of the accepted exception.

The 2nd referee will nonetheless tell you to get rid of all of them

Iirc, yed

I still remember trying to find the space group for Copper Telluride. No amount of technical terms could help me there.

Ngl I have mixed aqua regia to clean out my pestle and mortar in a lab course once. Shit went from uncleanable to clean really quick. H_2O_2 + conc. HCl is sufficient for most extreme cleaning needs tho.

It is fluorine indeed.

Dysprosium is an f-block element tho.

Iron? Manganese? I don't care what transition metal you are, at the end of the day you just want to fulfill your desire for d...

I'm sure there's a better version of the joke out there, but being funny isn't my strength

I think no one around here realizes how fucking insane a 5 W laser pointer is, it's not blinding people level, it's more like, don't shine it at anything white or you might blind yourself level.

For reference the highest laser security classification starts at 0.5 W.

Maybe I'm exaggerating here but 5 W is definitely a lot.

So yeah, I'm down with the laser pointer.

Hot take: a McChicken isn't a basic good.

1. Light = energy, shorter wavelengths= higher energy. Blue light has a shorter wavelength than red light. UV has even more energy. X-Rays have a lot more energy. For reference in the visible spectrum were talking about maybe 1-4 eV (this may be wrong, I'm too drunk to look it up rn).

2. If we want to produce light, the aim is to find an energy gap that has the exact energy gap that corresponds to the wavelength we're interested in. Typically this corresponds to an electronic transition, i.e. an electron "jumps" into a higher orbital, on its way down it will emit the energy difference as light.

2.1 X-Rays rn are produced by accelerating electrons onto a metal plate with high voltage. The impact of the electron "rips" out an electron in the close vicinity of the nucleus. Another electron will take the place of that electron, the energy gap associated with that process is large, which is why it produces X-Rays.

3. If we want to produce LEDs that emit in the far UV range we have to find large energy gaps in materials which is difficult. We still have to have a way to get the electron across the energy gap using electricity.

4. X-Ray LEDs are probably not realistic, as the energy of x-rays is so large that we have to rip out electrons from the close vicinity of the nucleus... which is already what we're doing with X-ray tubes.
