Interesting. Looking at those diagrams I'm trying hard not to evaluate them with the eye of a protein structure expert (which I used to be, not anymore!). He says "I'm no biologist", which is of course no issue - anyone

Hah, I was not expecting to open up that page to see an image of a ribbon diagram of alpha-glucosidase. Also, links to 'Makeblock XY Plotter' seem to no longer work as it has been discontinued? (Don't recommend going to their

Apparently there used to be $10,000 bills : https://www.moaf.org/exhibits/checks_balances/abraham-lincol... With Salmon P. Chase on them. So you would only need 10,000 of these.

Scientific papers use (still?) stereo images, for example those made using ORTEP: https://www.umass.edu/molvis/francoeur/ortep/ortep.html although seeing something like an alfa-helix as 3D might require some

So ultramarine blue ( https://en.wikipedia.org/wiki/Ultramarine ) is made from lapis lazuli which is a semi-precious stone. That was presumably quite expensive.

I suspect it's a pun on the mineral name ... (Incorrectly, I assumed that the name related to 'vital' - as in 'living' - but apparently not : "It was named by Abraham Gottlob Werner in 1817, the year of his dea

Wacky structure! Not just a cage, but also has 2 B-H-B bonds ( https://en.wikipedia.org/wiki/Three-center_two-electron_bond ) - no wonder it is so reactive...

Yes, I've learned some techniques after reproducing a lot of Islamic patterns, which can be done entirely with straightedge and compass (although frankly I often 'cheat' by using measures, grid paper and tracing paper, lol).

There absolutely are when it comes to materials like pens, but I bought a set of 3 pens (0.1 mm, 0.3 mm, 0.5 mm) for less than ten GBP. Specifically, Mitsubishi pencil co. unipen fine line. Sure you can probably buy much more expensive exam
