It glows in exactly the same way glowing silly putty does. Photons excite electrons in a atom, which over time become unexcited, and release the energy back as photons of a specific wavelength depending on the atom.

The Krukenberg procedure is used when people loose hands in countries where it would be too expensive to get prothstesis. The pincers have about the same strength as your thumb. Pretty cool work around.
Many like it better because it retains the ability to touch

linguistics is a fascinating field

 No.7604

>>7603
Indeed it is. One thing recently that I've found super interesting is how many rules about English that native English speakers know, but can't name. This may be known amongst some of you but, I'll still share.

Firstly, adjectives in English are always in the order of opinion, size, age, shape, color, origin, material, purpose, and then the noun. An example might be, "Great big old circular golden German wooden rocking chair". However, if you move any of those words before "chair" around, the sentence sounds alien and awkward.

There's also the rule of ablaut reduplication. Do you know what it is? Probably not. However, if someone said "hop-hip" or "zag-zig", you'd know those are wrong, but you wouldn't know why. It sounds wrong because of ablaut reduplication. If you repeat a word with an altered vowel, the word with an "i" as the vowel has to go first. Zig-zag, hip-hop, chit-chat. In phrases with three words, it's got to go I-A-O.

I found this fascinating video on why the space shuttle was a failure. It was originally a much more ambitious project.
What "could have been" if we used nuclear rockets to explore space, is sad in retrospect. So much potential was lost.

I felt as though their explorations probably produced lots of scientifically significant discoveries that didn't make interesting viewing. At the same time they didn't want to just re-run what they showed the first time around, so we got something in between that was mutually unsatisfying

Ive never seen this type of joint used anywhere. It seems weak, hard to lubricate, extremely hard to machine, and very prone to grit getting between the teeth.
We use Constant Velocity joints in car axles. Universal joints have effect that at an angle the output wont spin at a steady rate. CV joints use a system of ball bearings to transmit torque at an angle without changing speed

My parents bought a chunk of bismuth. This shit doesnt even look real in pictures.

>The spiral, stair-stepped structure of bismuth crystals is the result of a higher growth rate around the outside edges than on the inside edges. The variations in the thickness of the oxide layer that forms on the surface of the crystal cause different wavelengths of light to interfere upon reflection, thus displaying a rainbow of colors.
