Gaupol Updated +Created
Good shortcuts and user experience.
No waveform viewer: github.com/otsaloma/gaupol/issues/49 so unusable.
Oak Ridge supercomputer Updated +Created
Cirac–Zoller controlled-NOT gate Updated +Created
Vim Updated +Created
Before we get a decent open source integrated development environment, what else can you do?
But also perfect for small one-off files when you don't have the patience to setup said IDE.
vim's defaults are atrocious for the 21st century! Vundle is reasonable as an ad-hoc package manager, but it can't set fixed versions of packages:
D-Amino acid Updated +Created
The rare ones. Notably present in peptidoglycan.
German (language) Updated +Created
History Updated +Created
Hindi Updated +Created
Title sequence Updated +Created
Phase-contrast microscopy Updated +Created
Intelligence analysis Updated +Created
International Standard Music Number Updated +Created
Why was this so rarely used as of 2020s compared to ISBNs? It would have been perfect for helping find obscure records from Chinese traditional music and Indian classical music!
But instead we have Discogs, which is not too bad.
Islam character Updated +Created
Islam has some really nice things in it.
The way it was perverted to be used as a tool for terrorism by some is a great tragedy.
Ciro Santilli especially appreciates the ideas of
  • Ramadan
  • modesty, e.g. as shown by everyone wearing similar clothes
  • symbolism being explicity forbiden, much like for Protestantism
  • huge importance given to giving to the poor
Oxford Nanopore MinION Updated +Created
One of the sequencers made by Oxford Nanopore Technologies.
The device has had several updates since however, notably of the pore proteins which are present in the critical flow cell consumable.
Official documentation: nanoporetech.com/products/minion (archive)
The following images of the device and its peripherals were taken during the experiment: Section "How to use an Oxford Nanopore MinION to extract DNA from river water and determine which bacteria live in it".

Photon polarization Updated +Created
The knowledge that light is polarized precedes the knowledge of the existence of the photon, see polarization of light for the classical point of view.
The polarization state and how it can be decomposed into different modes can be well visualized with the Poincaré sphere.
One key idea about photon polarization is that it carries angular momentum. Therefore, when an electron changes orbitals in the Schrödinger equation solution for the hydrogen atom, the angular momentum (as well as energy) change is carried out by the polarization of the photon!

  • clear animations showing how two circular polarizations can make a vertical polarization
  • a polarizer can be modelled bra operator.
  • light polarization experiments are extremely direct evidence of quantum superposition. Individual photons must be on both L and R states at the same time because a V filter passes half of either L or R single photons, but it passes all L + R photons
Trinity (nuclear test) Updated +Created
Plutonium-based.
Its plutonium was produced at Hanford site.

Hand-waving Updated +Created
First we hand-wave some intuition. Then we prove. That's the way to teach.
