Point-contact transistor Updated +Created
The first working one in 1947 by John Bardeen and walter Brattain in Bell Labs Murray Hill.
People had already patented a lot of stuff before without being able to make them work. Nonsense.
As the name suggests, this is not very sturdy, and was quickly replaced by bipolar junction transistor.
Public Schools Act 1868 Updated +Created
They actually abolished the original legal requirement for those institutions to have free scholars as set out by their original charity school beginnings!!! WTF!
But the broadening of scope beyond the Church of England/medieval material was a good thing at least.
Aminoacyl tRNA synthetase Updated +Created
Binds an amino acid to the correct corresponding tRNA sequence. Wikipedia mentions that humans have 20 of them, one for each proteinogenic amino acid.

Debugging Updated +Created
Debugging sucks. But there's also nothing quite that "oh fuck, that's why it doesn't work" moment, which happens after you have examined and placed everything that is relevant to the problem into your brain. You just can't see it coming. It just happens. You just learn what you generally have to look at so it happens faster.

The most comprehensive list is the amazing curated and commented list of quantum algorithms as of 2020.
Quantum approximate optimization algorithm Updated +Created
TODO clear example of the computational problem that it solves.

Pleistocene Updated +Created
Agriculture is not the official definition of the age. But it is good enough. Likely related to the official end of glaciations thing.
Projective space Updated +Created
A unique projective space can be defined for any vector space.
The projective space associated with a given vector space is denoted .
The definition is to take the vector space, remove the zero element, and identify all elements that lie on the same line, i.e.
The most important initial example to study is the real projective plane.
Protein degradation Updated +Created
proteins also have a half-life, much like RNA. But it tends to be longer.

The simplest multicellular species Updated +Created
One of the simplest known seems to be: en.wikipedia.org/wiki/Trichoplax
www.u-tokyo.ac.jp/focus/en/articles/a_00220.html "The simplest multicellular organism unveiled" from 2013 mentions Tetrabaena socialis.
Then of course: Caenorhabditis elegans is a relatively simple and widely studied model organism.
