Since pure thallium can be poisonous to the touch...does that make it death metal?

The Cl(4,1,1) unified electromagnetic field theory: https://crudfactory.com/PHYSICS.html
Key points:
* It is one equation
* It yields Maxwell’s equations
* It yields Newton’s law of gravitation
* It explains Michelson-Morley
* It yields a proof of inertial mass
* It yields digital parallel Grover’s algorithm
When combined with axiomatic probability theory and the principle of maximum entropy, it becomes a basis for all academic fields to intercommunicate.
🧱 The secret ingredient holding the Great Wall of China together is sticky rice.
Ming Dynasty masons (1368-1644) mixed boiled sticky rice soup into their lime mortar. The result was a tough, flexible, water-resistant binder that has held brick sections together for around 600 years.
The chemistry: sticky rice is packed with amylopectin, a complex starch. In 2010, chemists led by Bingjian Zhang at Zhejiang University found that amylopectin acts as a template, steering calcium carbonate crystals into a dense, interlocking structure instead of large brittle chunks.
That compact microstructure is why some wall sections have shrugged off earthquakes and still keep weeds out of the seams centuries later.

Glad UC Riverside still has a scientific glassblower. Fewer and fewer US campuses do.

Just found out I wasted 3 weeks of work, a significant amount of solvent and other reagents because the commercial starting material is not what the bottle says it is to add insult to injury what is in the bottle isn't even clean, there is at least one other thing in there.
Hilariously (not really) the only reason I determined this was because I'm making something from the literature and none of my spectra were matching close enough. Went back to the start to check and remade the first step, it produced the same wrong thing. Tried some other conditions, same deal. Finally took an NMR of the starting material today.
