Process Simulation Software FREE Download - Aspen Hysys versus DWSim | COCO by Jeferson Costa (2020)
Source. Jeferson, a Brazilian from Petrobras, is the creator of the open source DWSim software, and in this video he gives a quick demo of his software and compares it briefly to aspen HYSYS, which appears to be the golden paid reference implementation.

Chemistry is fun. Too hard for precise physics (pre quantum computing, see also quantum chemistry), but not too hard for some maths like social sciences.
And it underpins biology.

100 Greatest Discoveries - Chemistry by the Discovery Channel (2005)
Source. Pretty good within what you can expect from popular science. The discovery selection is solid, and he interviews 3 Nobel Prize laureates, only one about stuff they invented, so you can see their faces. The short non-precise scenes of epoch are also pleasing. Part of 100 Greatest Discoveries by the Discovery Channel (2004-2005).

The key is to define only the minimum number of measures: if you define more definitions become over constrained and could be inconsistent.
Learning the modern SI is also a great way to learn some interesting Physics.
Protein tag Updated 2025-07-16
You modify the DNA of a cell and stick a fluorescent protein right before or after another protein. Then when it gets translated, the GFP is stuck to the protein of interest, which hopefully hasn't lost its function as a result, then you can just see the protein of interest.
These are two conflicting constraints:
