Rediscovering Réaumur: The Forgotten Temperature Scale | May 28 2026, 21:48

LOL, it turns out that besides Fahrenheit and Celsius scales, there was another scale, and relatively recently. The attached photo is mine, taken in 2009 in Baku at a friend’s house.

So where did this Réaumur come from? In 1730, he proposed a temperature scale, one degree of which equals 1/80 of the difference between the boiling point of water and the melting point of ice. Why 80? Because it’s easier to remember, although in fact Réaumur took only one reference point – the melting point of ice. Hence, the “zeros” of the Celsius and Réaumur scales coincide. And one degree of Réaumur corresponds to a temperature change during which the volume of alcohol increases or decreases by 1/1000.

In Réaumur’s days, there were already several different scales, including the widely known Fahrenheit scale, which is still used in some countries, including the States (and which I have never gotten used to). In France, the use of this scale was abolished on April 1, 1794, in connection with the transition to the metric system. The Réaumur scale was used in Tsarist Russia until the 1917 revolution. But in general, the 18th century was a mess with this, and few people know that besides these Kelvin, Celsius, and Fahrenheit, their scales were also invented by Rankine, Rømer, Newton, Delisle, and Réaumur.

Human Behavior Under Isolation: Lessons from the SPHINX Experiment | May 10 2026, 18:01

In the book Project Hail Mary, Stratt tells Grace that in the USSR there was supposedly an experiment where people were locked up for several months to see what would happen, and that the people almost killed each other, leading to the experiment being halted. That wasn’t the case, but I googled and found there was another experiment – SPHINX in 1999.

There were several groups. In the first, there were four Russians and during the New Year celebrations with alcohol, they beat each other up (10 minutes, blood, they had to be pulled apart). Another group had three guys and a girl (Judith Lapier) and the mission ended because during the New Year’s celebrations, driven by excitement, Judith was attempted to be kissed twice, leading to the mission being terminated.

As VICE reports, the dialogue was “We should try kissing, I haven’t smoked for six months. Then we can kiss after the mission and compare. Let’s experiment now.”

The team included doctors with degrees (Lukyanuk, Karashkin, Murashov) and Haider Hobikhozhin, who essentially was a randomly included technician with secondary education, taking the place of the Japanese man to the right in the photo and who was first in the second photo. Who beat up or kissed whom is now somewhat forgotten.

Vadim Gushchin, a coordinator from IMBP, after the scandal stated that the fight was “friendly,” and that Lapier “ruined the mission, the atmosphere, by refusing to be kissed.”

At the Canadian Space Agency, Lapier was told that such behavior is normal for Russians and that public complaints would be considered taboo in the culture of the host country.

Taste and Protest: Unveiling the Symbols at an Iranian Restaurant | May 03 2026, 19:40

A very tasty Iranian restaurant. Perhaps you didn’t know, but there are two flags of Iran. This one – the historical flag, used before the Islamic revolution of 1979, and today its use inside Iran itself is a political crime. The main difference from the official one is the emblem of the lion and the sun. Therefore, when Iranian protesters in Washington hold demonstrations, it’s interesting to see which flags they carry. If there’s four crescents and a sword in the middle, those are protesters from another camp 😉

Exploring Word Clusters in Religious Texts from Gutenberg’s Library | May 02 2026, 03:28

It’s interesting that if you take 8000 books from the Gutenberg library and construct a graph for each based on word connections to see how “friendly” words are—if word A often appears with B, and B with C, then how often does A appear with C? There’s a metric for this—the average clustering coefficient. Then, simply sort the books by decreasing this coefficient, about 70 percent of the top will be religious books—bibles, the Book of Mormon, the Quran. Well, some of them are duplicates in a sense, because a Bible in different formats remains the Bible. But clearly, its different parts are grouped together, meaning, they definitely share commonality in these triangular words.

But what unites all the books in this top— is that they were written many years ago or, as in the case of The Night Land, written relatively recently in the same style as many years ago.

By the way, among these books shines An Introductorie for to Lerne to Read, To Pronounce, and to Speke French Trewly. This is a French language textbook, written in English during the Tudor times (around the 1530s). Soverayn lorde kyng Henry the Eight. It was written by Gilles Du Guez—a French teacher at the English court. This particular textbook was compiled for Princess Mary (the future Queen Mary I, known as “Bloody Mary”), the daughter of Henry VIII. Check out a page from the textbook. Very cool English 🙂 …ye must pronounce it letyng your lippes jointe close, so that there be but a lyttell hole in the middes.

So, I delved into this textbook. It mentions a fruit called “openarses.” As you understand, this is “open arses” in English. In Tudor England, they called a medlar an openarse. If you Google what a medlar looks like, you’ll have no questions why it’s called openarses 😉

In the anatomical section (MEMBRES LONGYNG TO MANNES BODY), the author mentions next to the eyes and ears “the nether beerde” (literally— “the lower beard”).

From Wooden Puppet to Beloved Boy: The Evolution of Pinocchio’s Tale | May 01 2026, 16:52

It turned out that initially Carlo Collodi, who wrote “The Adventures of Pinocchio,” did not intend to turn his hero from a wooden puppet into a real boy. Pinocchio was destined to be hanged by the Cat and the Fox on an oak tree—as a lesson to all children who lie and disobey their elders.

The author was persuaded to continue Pinocchio’s adventures by the editor of the “Children’s Newspaper,” who said that otherwise it would be their last publication. The readers were so outraged by the death of the hero that the editorial office was inundated with letters demanding a continuation.

Eventually, after a few months, the author was forced to “resurrect” the puppet. This is how the Blue Fairy appeared in the story, who saved Pinocchio from the noose, and the grim parable gradually turned into the familiar fairy tale with a happy ending.

When Pinocchio was already hanging on the oak tree and gasping for air, a Beautiful Girl with Azure Hair appeared at the window of a nearby little house. At that moment she is described not as a kind fairy, but rather as a ghost or spirit (she says that everyone in this house died, and she too is waiting for her coffin).

Seeing the puppet dangling from the tree, she took pity and organized a whole rescue team. The fairy clapped her hands three times. A giant Falcon arrived. She ordered him to fly to the Great Oak, gnaw through the rope with his beak, and carefully lower Pinocchio onto the grass. Then she summoned her servant—a poodle named Medoro. He was dressed in festive livery, with a cocked hat and a curly wig. Medoro was sent for Pinocchio in a luxurious carriage drawn by a hundred pairs of white mice. When the puppet was brought to the castle, he was neither alive nor dead. To decide what to do next, the Fairy summoned “luminaries” of medicine. By Pinocchio’s bed came the Crow, the Owl, and the Talking Cricket (the same one that Pinocchio “killed” at the beginning of the book, but he returned as a spirit).

Harsh.

Essentially, the hero owes his happy ending not to the author’s mercy, but to commercial success and public pressure.

Near-Miss at Leningrad: The Unknown Predecessor to Chernobyl | April 26 2026, 17:32

On the anniversary of Chernobyl. Those interested in this topic may not know that a similar accident could have occurred ten years earlier on the main (very first RBMK-1000 unit) Leningrad Nuclear Power Plant.

There was a nearly identical situation: one turbine in operation, reactor shutdown by emergency protection, and subsequent power escalation.

Back then, the situation was saved by the Chief Reactor Operator Mikhail

Karrask, who, acting intuitively and relying on his experience with industrial reactors, introduced into the reactor in portions

12 manual control rods

BEFORE pressing the emergency shutdown button.

A couple of years ago, Karrask passed away. This story is almost unknown outside the industry. For proof, google his obituary on Rosatom.

The technical part. The main danger of the RBMK reactors at that time was in the design of the control rods. At the bottom, they were equipped with graphite “displacers”. When the emergency shutdown button was pressed, the rods began moving down, and in the first seconds, the graphite tips did not dampen the reactor, but on the contrary, displaced the water and increased the power in the lower part of the active zone. But precisely, the instructions in case of trouble suggested pressing the emergency shutdown button. If you followed the instructions, “Chernobyl” would have happened earlier.

After the incident at the Leningrad NPP, a commission was formed. Experts (including those from the Kurchatov Institute of Atomic Energy) pointed out the dangerous design flaws of the RBMK – the positive void coefficient of reactivity and incorrect design of the rods. Unfortunately, extensive changes to the design of all RBMK reactors were not made at that time. Only operational regulations recommendations were given, which, as history showed, were insufficient to prevent the tragedy in Chernobyl.

Nikolai Nosov’s Anticipated Instagram: Art Templates and Avatars | April 07 2026, 13:04

As early as 1954, Nosov predicted the emergence of Instagram

P.S. It’s just not very clear why there are different templates for different eye and hair colors.

Space Exploration: From Pioneering Days to the ISS as a Playground | April 06 2026, 19:59

Mapping Global Friendships and Rivalries: A Color-Coded Matrix Analysis | March 12 2026, 03:29

For fun, I decided to make a matrix of who is friends with whom and who is enemies with whom. For each country-country pair, I asked Gemini which of the five categories the relations fall into: “at daggers drawn” (purple), “predominantly unfriendly” (red), “neutral” (yellow), “predominantly friendly” (blue), “friends” (green). Lisa said that “neutral” should be purple. Overall, the quality of Gemini’s assessments is quite good.

Among all countries, three red lines stand out. These are countries that are on very bad terms with many others. Well, you guessed Russia right. And what is the second country? Israel? No, it’s Belarus and Venezuela.

In the top five countries that everyone is friends with and who have many friends themselves, LLM included the USA, United Kingdom, Canada, France, and Germany. There is an anti-rating – these are countries that have very bad relations (“at daggers drawn”) with many others. In this rating, Russia is in first place with 21 countries, and Israel is in second place with 18 enemies. Following them, with a significant gap, are Syria and the USA with 9 enemies each. There is also a separate Conflict Zone rating – this is the sum of red and purple. Russia, Venezuela, Belarus, Israel, USA, Iran, Ukraine.

There is a “pacifists’ club”. These are the ones who have no enemies at all, sorted by the number of friends. Rating: Bahamas, Vatican, Luxembourg, Angola, Singapore, Iceland, Jamaica, Tanzania, Zambia.

I was curious, what if I apply the formula: the enemy of my enemy is my friend? What would change? This led to new colors on the matrix – logic friends.

The most unexpected leader of the Master Pragmatists ranking was Taiwan (25 logical connections). Why so? In the logic of LLM, Taiwan is a country that is officially recognized by few, but because of its global opposition to China, it automatically becomes a “logical friend” for everyone who has strained relations with Beijing. This is confirmed in the Shadow Bridges section: Taiwan has 23 connections beyond its region. It literally “stitches” different parts of the world together through a common problem.

The report “Secret Partners” – a list of geopolitical oxymorons. These are pairs that are “at daggers drawn” in official news but are forced to be friends by Gemini’s calculation. For example, Afghanistan – USA/United Kingdom. Despite the status “rather bad relations”, Gemini’s logic sees them as “logical friends”. Possibly due to common regional threats (like ISIS) or dependence on humanitarian and back channels. Or here’s a strange alliance “Belarus — Hungary”. Nominal — different camps, factually — similar style of rhetoric and common “enemies” in Brussels. Eritrea — Ethiopia: Status “at daggers drawn”, but at the same time, they became logical friends.

In the report “Most Controversial,” the first places are taken by the USA, and then with a significant gap, Russia, and even larger – United Kingdom, Canada, Ukraine. These are countries with the highest Love x Hate product value. That is, countries that have many friends and enemies at the same time.

Another report – the indifferent ones. About them, LLM couldn’t say much, apparently because they bother no one (both literally and figuratively). There are, for example, Madagascar and Haiti.

I also tried to cluster by the strength of friends and got four groups of countries.

The largest cluster. Core: China, Russia, Iran, India, and BRICS+ countries, as well as almost the entire African continent (from Egypt to South Africa) and a significant part of the Middle East (UAE, Saudi Arabia, Qatar).

The second cluster mainly included European countries. Core: France, Germany, United Kingdom. The algorithm determined Ukraine and Israel to be here. Logically: their survival depends on “predominantly friendly relations” with the European core. In this same club are Armenia, Georgia, and Serbia. Apparently, despite all the political swings, Gemini considers their ties to Europe more fundamental than any others.

The third cluster included the USA, Canada, Brazil, Mexico, and, for example, Taiwan. Officially, it can be a “logical friend” to all of China’s enemies, but by “strength of friends,” it is permanently sewn to the American block. The Vatican also ended up here, which makes this club not only economic but also somewhat “values-based.”

The fourth cluster, the most compact and specialized, included countries of Oceania and Southeast Asia. Leaders: Australia, Japan, New Zealand, Singapore. This turned out to be a club of countries trying to balance in the most complex region of the planet. Here are almost all island states (Fiji, Samoa, Tonga).

What else could we extract from this information?
