Exploring Science and Myth through the Engineering Zen Group | August 03 2026, 15:37

I remind you that I have a group called Engineering Zen on Facebook and Telegram. Recently, there have been posts about:

– How for half a century science condescendingly explained to grandmothers that colds are caused by viruses, not drafts, — and in 2022, it found a mechanism by which grandmothers were partly right.

– People who are currently walking around with plutonium in their chests. Legally, registered with the nuclear regulator, with the instruction “to be returned to the state after death.” The capsule was seriously tested: cremation, plane crash, shotgun blast. It wasn’t radiation that killed the technology.

– Old sailors who poured oil overboard during storms. Not superstition, but working physics — and from it emerged, it seems, the first measurement of the size of a molecule in history. A teaspoon of oil, a pond under London, and Benjamin Franklin. Today, the same effect captures oil spills from satellites.

– Why almost all blue in the animal world is a deception: there’s no pigment at all. Neither in the wings of the morpho butterfly, nor in the feathers of a peacock, nor in your blue eyes. Mammals do not have any blue pigment. But it’s the opposite in plants.

– How the ocean floor is mapped… by looking at its surface from space. Underwater mountains betray themselves through “bumps” on the water — it turns out the sea is not flat at all. Only about a quarter of the sea floor has been measured with a sonar to this day.

– The MRI magnet, which is turned on only once in a lifetime — and then it circles current through a ring for years, without any socket. Even at night, when the clinic is closed. But if the cooling fails — a “quench” occurs, and tons of helium burst out through the pipe to the roof within seconds.

– The theorem by which a sphere can be cut into pieces and assembled into two identical spheres. Not a trick or sophistry — honest mathematics. The catch is that these “pieces” have no volume. At all. Like the coast of Britain has no length.

– Why in a language with three words for colors, the third is always red, and blue appears last. No need to know the language — just count. And why the go signal on Japanese traffic lights is legally “blue.”

– A rescue operation going on in space right now: a robot trying to catch a falling telescope, which has neither handles nor a docking unit — it was built in an era when no one thought of such things. Racing against the atmosphere.

– Lunar dust — the main nightmare of lunar bases. Microscopic sharp glass shards that eat away space suits within hours, stick to everything due to static, and — surprisingly — smell like gunpowder.

– A hypothesis that lasted 85 years and fell during the World Cup final — from a single line on Twitter. A counterexample is verified by a student in a minute, and it’s unclear why it wasn’t found earlier.

– The illusion of “stopped clocks,” which everyone has experienced: you shift your gaze to the second hand — and it has stopped. It turns out, the brain blinds you several times a second — and then edits time retrospectively.

– Ice that does not melt at +300°C — found trapped inside diamonds from the Earth’s mantle. And its even more strange black superheated relative seems to make up the interiors of Uranus and Neptune.

– Why the ads on the stadium boards, which you see on television, physically do not exist — viewers in Brazil, Germany, and Japan see three different sponsors at the same moment.

– A piece of wire mesh that tames fire where it is bound to explode — and on which the entire century of mining labor stood. The inventor gave it to the world for free.

– And for dessert — why a giant NASA rocket is transported not on asphalt, but on river pebbles. They tried asphalt — it went “in waves, like the sea.” Personally verified, I spent an hour looking at that gravel out the window.

Join us to not miss much more interesting stuff.

P.S. There is also a group in Telegram with the same name, but there the audience has stopped growing at all and stands at about 100 people, and until I figure out how to manage this, I am temporarily giving up on it.

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 😉

When the Night Lit Up: Unraveling the Mystery of a Superbolt Storm | March 21 2026, 12:55

We had a thunderstorm last night. The whole county is buzzing because everyone thinks that something exploded just before midnight. Several posts in a row on social media. In short, it was thunder. But a bit more rare than usual. Caused by a 401 kA lightning, dubbed the Wild House Shaker. A typical lightning strike is 30 kA. If the numbers are to be believed, 401 kA is really damn a lot. They will likely say we haven’t had such lightning here for decades.

Attaching an interesting map.

The points on the map show superbolts — lightning strikes with an energy of no less than 1M J. Red points — particularly powerful superbolts with an energy of more than 2M J. That is, superbolts mostly occur in the northeastern part of the Atlantic and in the Mediterranean Sea, and less frequently — in the Andes, off the coast of Japan, and near South Africa.

this is what the page from which I took the map says (translation):

“New work shows that superbolts most often occur over the Mediterranean Sea, the northeastern Atlantic, and over the Andes, as well as in smaller amounts to the east of Japan, in tropical oceans, and near the southern tip of Africa. Unlike regular lightning, superbolts often strike over water.

“Ninety percent of lightning occurs over land,” said Holzworth (that’s the main guy on lightning at the University of Washington).

“But superbolts mostly arise over water, right up to the coastline. For example, in the northeastern Atlantic, the distribution maps of superbolts clearly show the outlines of the coasts of Spain and England.”

“The average energy of a discharge over water is higher than over land—that we knew,” he said. “But we did not expect such a stark difference.”

The season for superbolts also does not match the usual patterns of lightning. Regular lightning most often occurs in the summer—the three main so-called “lightning chimneys” coincide with summer thunderstorms over America, Africa south of the Sahara, and Southeast Asia. However, superbolts, which are more common in the Northern Hemisphere, occur in both hemispheres from November to February.

The reason for such a distribution remains a mystery. In some years, there are significantly more superbolts than in others: the end of 2013 was record-breaking, and the end of 2014 was the second largest, while in other years such events were much less frequent.

“We speculate that this may be related to sunspots or cosmic rays, but we will leave that for future research,” said Holzworth.

“For now, we are just demonstrating that there is a previously unknown pattern.”

Navigating Without GPS: Understanding Cardinal Directions in Moscow | March 13 2026, 18:41

The spokesperson for the Phystech press service explains how to determine cardinal directions in Moscow when navigation systems are down. Find the North Star or use the sun: it rises in the east and sets in the west. Also reminds us how to determine directions using trees. Ziya, do you know how to find cardinal directions using trees? — What’s there to know? Fir tree points north, palm tree points south!

Overall, it seems the Phystech press service is not aware that in Moscow, the annual amplitude of sunrise point movement is almost 90 degrees. That means, it only sometimes (like now, in March) actually coincides with the east. But they do know the word “asterism”. I think most readers will place it somewhere near the word “flatulence”

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?

The Curious Etymology of the Turkey: Naming Perceptions Across Languages | March 09 2026, 21:36

I wondered why turkey is called turkey here and what it’s called in Turkey. In Turkey, it’s called hindi – turkey! Decided to see what it’s called in India. Haha, in Hindi, it’s called Turkish (टर्की). Let’s see in other languages. Portuguese – Peru. That means, for them, it’s Peruvian. In Spanish – pavo, which refers to peacock 🙂 “pavone” in Italian – peacock. In French – dinde, because this bird came from the West Indies (America). Comes from poule d’Inde – “hen from India/West Indies”. Greek – “Γαλοπούλα” “French bird”.

Exploring Redundancy in Toponymy: From European Rivers to the Hill of Hills | March 08 2026, 02:54

Reading Nabokov, there “…with the dash of the Danube in his veins…”. Turns out, Danube is Дунай. But that’s okay, trivial stuff, the interesting thing is something else. That Don, Danube, Dniester, Dnieper, Donets, Dvina, and Disna essentially mean more or less the same thing – river. Apparently, the ancient people were not always rich in imagination when it came to toponymy. If you live by the water, you simply call it “River”. Over time, others came, heard this word, took it as a proper name, and altered it slightly to fit their accent. This way “River” (Danu) transformed into a dozen different names across the map of Europe.

The river Volga essentially is also just “river”. Okay, slightly different, “Volga” comes from the Proto-Slavic *Vòlga, which literally means “moisture” or “water”.

Also, it turned out that the Sahara desert is named so because Sahara (الصحراء) is desert. And the Gobi desert is called Gobi because Gobi in Mongolian is desert.

While googling, I stumbled upon another fun thing. There’s a place in England, Torpenhow Hill. The name is composed of four different linguistic layers: Tor — in Old English “hill”, Pen — in Cumbric “hill”, How — in Old Norse “hill”, Hill — in modern English “hill”. Result: “Hill-hill-hill-hill”. Likely, each new people arriving in this area didn’t understand that Tor, Pen, and How were already names for the hill, and added their variant of the word “hill”.

Redefining Third World: Beyond Cold War Labels | March 07 2026, 03:36

Today I read that the Third World countries were initially countries not part of NATO (First World) or the socialist bloc (Second World), that is, countries such as Sweden, Switzerland, Finland, Ireland, and Austria. Some still use the term “developing countries,” where it is customary to include low-income countries, but, darn it, a developing country is actually a good definition. The one that has developed and stopped developing – that’s a signal. Incidentally, Qatar, which has the highest GDP per capita in the world, is formally considered developing.
