Bitcoin addresses are by convention expressed in Base58, which is a human readable binary-to-text encoding invented by Bitcoin. It is a bit like Base64, but obsessed with eliminating characters that look like one another in popular but stupid fonts like capital "I" and lower case ell "l".
This seems to be one of the earliest strategies used to encode messages.
These messages were originally found with: github.com/cirosantilli/bitcoin-inscription-indexer#payload-size-out-utxo-2vals
The generated text is however rather obfuscated by the limitations of Base58.
The following transactions contain base58 encoded messages on addresses:

- 623463a2a8a949e0590ffe6b2fd3e4e1028b2b99c747e82e899da4485eb0b6be and 5143cf232576ae53e8991ca389334563f14ea7a7c507a3e081fbef2538c84f6e both have 3,075 outputs of 1 satoshi each and a single input. We were not able to identify any meaningful data in it,
filejust saysdata, and there aren't long ASCII strings. However, the outputs were unspent as of 2021, which suggests that they might actually be data.
Analysis of some of them follows.

filesays their payload is a DOS executable, but it must be a coincidence
Matrix congruence can be seen as the change of basis of a bilinear form by Ciro Santilli 35 Updated 2025-01-04 +Created 1970-01-01
Ciro Santilli 35 Updated 2025-01-04 +Created 1970-01-01From effect of a change of basis on the matrix of a bilinear form, remember that a change of basis modifies the matrix representation of a bilinear form as:
So, by taking , we understand that two matrices being congruent means that they can both correspond to the same bilinear form in different bases.
Some nice insights at: Robert Noyce: The Man Behind the Microchip by Leslie Berlin (2006).

This was the first infinite family of simple groups discovered after the simple cyclic groups and alternating groups. The first case discovered was by Galois. You should understand that one first.
Used to explain the black-body radiation experiment.
Published as: On the Theory of the Energy Distribution Law of the Normal Spectrum by Max Planck (1900).
The Quantum Story by Jim Baggott (2011) page 9 mentions that Planck apparently immediately recognized that Planck constant was a new fundamental physical constant, and could have potential applications in the definition of the system of units (TODO where was that published):This was a visionary insight, and was finally realized in the 2019 redefinition of the SI base units.
Planck wrote that the constants offered: 'the possibility of establishing units of length, mass, time and temperature which are independent of specific bodies or materials and which necessarily maintain their meaning for all time and for all civilizations, even those which are extraterrestrial and nonhuman, constants which therefore can be called "fundamental physical units of measurement".'
TODO how can it be derived from theoretical principles alone? There is one derivation at; en.wikipedia.org/wiki/Planck%27s_law#Derivation but it does not seem to mention the Schrödinger equation at all.
