Can you just imagine what if luminiferous aether was one single fixed rigid body? This is apparently what Maxwell believed, Subtle is the Lord by Abraham Pais (1982) page 111 quoting his entry to Encyclopedia Britannica:Then it would provide a natural space coordinate for the entire universe!
There can be no doubt that the interplanetary and interstellar spaces are not empty but are occupied by a material substance or body, which is certainly the largest, and probably the most uniform, body of which we have any knowledge.
Machine learning Updated 2025-07-16
The main reason Ciro Santilli never touched it is that it feels that every public data set has already been fully mined or has already had the most interesting algorithms developed for it, so you can't do much outside of big companies.
This is why Ciro started Ciro's 2D reinforcement learning games to generate synthetic data and thus reduce the cost of data.
The other reason is that it is ugly.

Machine learning company Updated 2025-07-16
This section is about companies that primarily specialize in machine learning.
The term "machine learning company" is perhaps not great as it could be argued that any of the Big tech are leaders and sometimes, especially in the case of Google, has a main product that is arguably a form of machine learning.

Nice looking and expensive operating system by Apple. Ciro Santilli believes that:

- or if you want to attain Enlightenment, just use Linux, which is free and open source
Madelung energy ordering rule Updated 2025-07-16
Looking at the energy level of the Schrödinger equation solution for the hydrogen atom, you would guess that for multi-electron atoms that only the principal quantum number would matter, azimuthal quantum number getting filled randomly.
However, orbitals energies for large atoms don't increase in energy like those of hydrogen due to electron-electron interactions.
In particular, the following would not be naively expected:
This rule is only an approximation, there exist exceptions to the Madelung energy ordering rule.

Magic: The Gathering meta-based deck choice is a bimatrix game Updated 2025-07-16
Ciro had initially Googled for the "4-card limit thought experiment" but he reached: www.channelfireball.com/articles/what-if-the-4-card-limit-was-abolished-in-modern/ "What if the 4-Card Limit Was Abolished in Modern?" by Frank Karsten (2018) and was much more pleased with the mathematical result. Like-minded people.
That links to www.channelfireball.com/articles/what-if-the-4-card-limit-was-abolished-in-modern/ the related article: "The Mythic Invitational's Duo Standard Format Game Theory Optimized" by Frank Karsten (2019) which explains well how Nash equilibrium is naturally reached: if there is any imbalance, someone can take advantage of it, and then it rebalances. Therefore once you've calculated the equilibrium, your best course of action is to pick a deck at random from a list of possible winners.

Magnetic dipole Updated 2025-07-16
A tiny idealized magnet! It is a very good model if you have a small strong magnet interacting with objects that are far away, notably other magnetic dipoles or a constant magnetic field.
The cool thing about this model is that we have simple explicit formulas for the magnetic field it produces, and for how this little magnet is affected by a magnetic field or by another magnetic dipole.

Ciro Santilli's campaign for freedom of speech in China Updated 2025-07-16
Centerpiece: github.com/cirosantilli/china-dictatorship
Fully rendered at: github.com/china-dictatorship
The campaign has centered around publishing censored keywords on his Stack Overflow username, thus using his considerable Stack Overflow presence to sabotage the website in China. Here is an early web archive.
Chrysanthemum Xi Jinping with 六四 spice added by Ciro Santilli
. This was one of the profile pictures that Ciro Santilli used as part of his campaign.
Ciro later went on to prefer the "unmodified" Xi Jinping photo cover of some edition Xi Jinping Though, which also reminds Ciro very much of religious devotional pictures, e.g. those of Li Hongzhi.
Ciro understood that the best propaganda against a dictatorial enemy is recontextualized unmodified propaganda produced by the enemy itself. Their propaganda speaks for itself
Like most people in the West, Ciro has always been for political freedom of speech, and therefore against the Chinese government's policies.
However, the seriousness of the matter only fully dawned on him in 2015 when, his mother-in-law, a then a 63-year-old lady, was put into jail for 15 days for doing Falun Gong.
And all of this was made 100 times worse because Ciro deeply loves several aspects of China, such as food, language, art and culture, and saw it all being destroyed by the Communists: cirosantilli.com/china-dictatorship/does-ciro-santilli-hate-china
The rationale of this is to force the Chinese government to either:
- leave things as they are, and let censored keywords appear on Stack Overflow (most likely scenario)
- block Stack Overflow, and lose billions of dollars with worse IT technology
- disable the Great Firewall
In the beginning, this generated some commotion, but activity reduced as novelty wore off, and as he collected the reply to all possible comments at: github.com/cirosantilli/china-dictatorship.
This campaign has led him to have an insane profile view/reputation ratio, since many people pause to look at his profile. He is point "A" at the top right corner of Figure 2. "Scatter plot of Stack Overflow user reputation vs profile views in March 2019 with Ciro Santilli marked as A":
Ciro feels that the view count started increasing more slowly since 2020 compared to his reputation, likely every single Chinese user has already viewed the profile.
