Black hole Updated 2025-07-16
Semi-boring academic overview, but without reproducibility, or in a way that is too hidden for Ciro to have the patience to find it out.

Mentions some upload mechanisms, notably AtomSea & EMBII and Satoshi uploader.
Cursive script (East Asia) Updated 2025-07-16
As if Chinese character weren't evil enough, their fast hand written form is even more unintelligible. It is like Hell within Hell.
It is also very beautiful it must be said.
Eigendecomposition of a matrix Updated 2025-07-16
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:

This video was made in 1970, on Zakir's first visit to the USA. He and Aashish Khan (keeping taal next to him) had a guest residency at UW Seattle, under the ethnomusicology dept. set up by Robert Garfias.

Einstein solid Updated 2025-07-16
One important quantum mechanics experiment, which using quantum effects explain the dependency of specific heat capacity on temperature, an effect which is not present in the Dulong-Petit law.
This is the solid-state analogue to the black-body radiation problem. It is also therefore a quantum mechanics-specific phenomenon.
Electrical impedance Updated 2025-07-16
It really allows you to do alternating current calculations much as you'd do DC calculations with resistors, quite poweful. It must have been all the rage in the 1950s.

RSA vs Diffie-Hellman Updated 2025-07-16
As its name indicates, Diffie-Hellman key exchange is a key exchange algorithm. TODO verify: this means that in order to transmit a message, both parties must first send data to one another to reach a shared secret key. For RSA on the other hand, you can just take the public key of the other party and send encrypted data to them, the receiver does not need to send you any data at any point.
