Crystallography determination with a transmission electron microscopy instead of the more classical X-ray crystallography.

So, it turns out that Wikipedia does have a (ultra obscure as usual) mechanism for pull requests. You learn a new one every day.

A really good option to store educational media such as images and video!

Shame that like the rest of Wikimedia, their interface is so clunky and lacking obvious features.

There's a beauty in the portability of browser games.

The fact that the browser is not the main gaming platform as of 2020 shows how crappy web tech is. There is no fundamental reason why it shouldn't be so.

A recreational computer simulation!

Upside: it is easier to simulate zombies than it is to simulate intelligent humans and make them look convincing.

Downside:

Classic theory predicts that the output frequency must be the same as the input one since the electromagnetic wave makes the electron vibrate with same frequency as itself, which then irradiates further waves.

But the output waves are longer because photons are discrete and energy is proportional to frequency:

The formula is exactly that of two relativistic billiard balls colliding.

Therefore this is evidence that photons exist and have momentum.
