Internal hard drive likely removed from some old computer I lost track of, kept in a crappy case, incredible stuff.

Eigendecomposition of a matrix Updated +Created
Every invertible matrix can be written as:
where:
Note therefore that this decomposition is unique up to swapping the order of eigenvectors. We could fix a canonical form by sorting eigenvectors from smallest to largest in the case of a real number.
Intuitively, Note that this is just the change of basis formula, and so:
  • changes basis to align to the eigenvectors
  • multiplies eigenvectors simply by eigenvalues
  • changes back to the original basis

What a fantastic picture!
Spacetime diagram Updated +Created
Why should I care when I can calculate new x and new time with Lorentz transformation?
Answer: it can give some qualitative intuition on what is larger/smaller happens before/after based only on arguably more intuitive geometric considerations, without requiring you to do any calculations, see e.g. Figure "Spacetime diagram illustrating how faster-than-light travel implies time travel".

TODO vs Phylogenetic tree? www.visiblebody.com/blog/phylogenetic-trees-cladograms-and-how-to-read-them:
Cladograms and phylogenetic trees are functionally very similar, but they show different things. Cladograms do not indicate time or the amount of difference between groups, whereas phylogenetic trees often indicate time spans between branching points.

No one is capable of offering an official/more generalized (why can't Google Maps do this properly?) map than these people: wikishire.co.uk/map/#/centre=54.004,-4.500/zoom=7 So so be it.

Bicycles require too much maintenance Updated +Created
It is true, something Ciro Santilli often things about. One likely reason is that the world is broken and most cyclist are speed maniacs willing to put the time in. Unlike Dutch people where everyone cycles.
