This is likely a system that uploads text to the blockchain.

One example can be seen on the Marijuana plant.

Messages are uploaded one line per transaction, and thus may be cut up on the blk.txt, and possibly even out of order.

But because each line starts with j( you can generally piece things up regardless.

TODO identify. The first occurrence seems to be in tx e8c61e29c6b829e289f8d0fc95f9eb2eb00c89c85cfa3a9c700b15805451ae6a:

Besides ASCII art, the huge majority of images is encoded with the AtomSea & EMBII system/format. All images in that system will be documented in that section.

These were ordinals that were only indexed in later versions of the script. So to prevent changing the useless indices of existing ordinals, they gave them negative numbers.

The word "cursed" is a meme from the 2010/20s, e.g. knowyourmeme.com/memes/cursed-images--2.

The exact opposite of argument from poor design!

Show up when solving the Laplace's equation on spherical coordinates by separation of variables, which leads to the differential equation shown at: en.wikipedia.org/w/index.php?title=Legendre_polynomials&oldid=1018881414#Definition_via_differential_equation.

As of 2025, this company was by far the most well funded in the field.

It was founded by some of the authors of the influential paper Deep learning with coherent nanophotonic circuits.

Presented e.g. at youtu.be/t0yj4hBDUsc?t=456 from Video "Silicon Photonics: The Next Silicon Revolution? by Asianometry (2022)".

LinkedIn fully complies with censorship imposed locally by the Chinese government, and does so in a non-transparent way: cirosantilli.com/china-dictatorship/linkedin.

It is hard to understand what the point of that website is, as it is basically just a more closed version of Facebook, but alas, it has flourished as the only place where people post more useful content compared to Twitter and Facebook. In any case, Ciro just applies the same unfollow policy to all of them: aggressively filter your social media follows.

The equation that allows us to calculate stuff in special relativity!

Take two observers with identical rules and stopwatch, and aligned axes, but one is on a car moving at towards the $+x$ direction at speed $v$.

TODO image.

When both observe an event, if we denote:It is of course arbitrary who is standing and who is moving, we will just use the term "standing" for the one without primes.

Then the coordinates of the event observed by the observer on the car are:where:

Note that if $\frac{v}{c}$ tends towards zero, then this reduces to the usual Galilean transformations which our intuition expects:

This explains why we don't observe special relativity in our daily lives: macroscopic objects move too slowly compared to light, and $\frac{v}{c}$ is almost zero.

The following aspects of Maxwell's equations make no sense without special relativity:

When charged particle though experiment are seen from the point of view of special relativity, it becomes clear that magnetism is just a direct side effect of charges being viewed in special relativity. One is philosophically reminded of how spin is the consequence of quantum mechanics + special relativity.
