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 Tornado Warnings: Safety Over Probability in the US | March 16 2026, 17:59

Today a tornado warning was issued. A warning is issued if radar detects conditions favorable for the formation of a tornado. In the end, there was a little rain at the exact predicted time (within about 10 minutes). It came, poured down, and moved on. Everything was canceled everywhere. A bunch of people are still on edge. The principle in the USA: safety is more important than anything, even if the probability is nearly zero, if the consequences threaten life, a small probability is weighed against high seriousness and ultimately maximum protocols are activated. When assessing risk, the most pessimistic option is chosen because if you’re wrong – you remain responsible. People head down to basements, children are locked in gyms, etc.

Everything seems fine, but such a reaction to bad weather and similar troubles instills a behavior of excessive caution for life, and people simply choose comfort and are scared to death of thunderstorms and snowfalls. Not sure if this is right or wrong.

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?

Unmasking the Self-Interest Behind Global Giants and Altruism Claims | March 04 2026, 19:00

I don’t believe in the altruism of giants. When it comes to large states or billionaire corporations, believing that they are guided by “principles of good” and “the common good” appears, in my view, to be either naivety or dangerous self-deception.

The real goal always remains in the shadows. Why? Because if everyone understands the true intentions, achieving them becomes much harder and more expensive. Or more precisely, everyone does understand them; it’s just that the circle of those in the know is small.

Take “liberation wars.” When a dictatorship receives democracy at the point of a bayonet, it’s not about human rights. It’s a way to infiltrate another system and show who’s the “alpha.” There are always specific interests in that state. Simply put, it’s about creating a geopolitical “roof.” In certain cultures, respect is earned only through strength. If you don’t show dominance, you’re not listened to. But if you do show it, you get invited to the “council of elders” and asked to “solve some problems.”

If a corporation suddenly starts caring vehemently about the planet—look for the ulterior motive. Most likely, their old production method has become too costly to maintain and needs changing. But under the guise of “reducing emissions,” modernization is warmly welcomed. Tax breaks, grants, and the chance to earn on government contracts come as bonuses. Ecologically, it’s just a pretty façade for expense optimization.

Often, the initiative does not come from inside the system, but from outside. Example: A luxurious park with benches and ducks is being built in the area. Concern for people? Relatively speaking. The main stakeholders are developers. Apartments in buildings near the park cost 20-30% more and sell twice as fast. Whether it’s a business or a politician, they just support an idea that generates profit (financial or electoral) for specific groups.

Even the holy of holies—science—is not held up only by curiosity and the desire to create a better future for people. A huge part of discoveries is driven by mere vanity. For a scientist, it is important to leave a name for the ages, step higher in the hierarchy, or at least feel like a “rock star” at a profile conference. Personal ambitions move progress more effectively than an abstract desire to help humanity.

When tech giants launch free satellite internet or distribute cheap smartphones in developing countries (Africa, India), it’s presented as a “mission to connect the world.” The real interest—markets in the developed world are saturated. The only way to grow is to create new consumers. By providing “free” access, the corporation hooks people to its ecosystem, gains access to the biometric and behavioral data of millions who are yet not protected by privacy laws. It’s the colonization of the digital space in the 21st century.

The largest philanthropic organizations often spend billions fighting diseases or hunger. The real interest—tax optimization and “soft power.” Transferring assets to a foundation helps avoid inheritance or capital gains taxes. Meanwhile, the founder maintains control over the funds through the board of directors. A bonus is the status of being “untouchable” in the media: criticizing someone who “saves children” amounts to reputational suicide. It’s the best insurance against antitrust investigations.

Mass promotion of “agendas” in Hollywood is often seen as a triumph of liberal values. The real interest—risk minimization and audience expansion. Film studios are huge bureaucratic machines. For them, “diversity” is a checklist that insures against boycotts and scandals (which cost money). Additionally, by adding a character from a specific ethnic group, the studio automatically taps into that group’s local market globally. It’s pure reach arithmetic.

The world is ruled not by kindness, but by interests and hierarchy. And possibly, that’s even good—at least, it’s predictable and logical. This was all about the altruism of giants. But I very much believe in the altruism of individual people.

Tesla Model Y Conquers the Winter Wonderland: A Snowy Road Test | January 26 2026, 03:50

We tested our Tesla Model Y on a winter road in weather that almost one hundred percent of people here consider “unflyable.” I’m serious, on the way back, at 8-9 PM, we encountered the first private car on a four-lane highway after 45 kilometers of travel. Meanwhile, snowplows appeared literally every two minutes.

A lot of snow had built up, and then it started to rain. After a few hours of parking in a snowbank at a friend’s house, the car was covered with an inch-thick layer of ice. We even got a bit stuck on the exit, but together we managed to push the car out of the “snow pit”. The most challenging part is the last mile on small paths, which the machinery doesn’t clean quickly enough. Now, I’m writing at 10:30 PM, and right outside my window a tractor is clearing the driveways, while in most places, this is usually the homeowners’ responsibility, and of course, everyone prefers to wait it out. Actually, we didn’t even make it to the friend’s house because the last 100 meters were just knee-deep snowdrifts, and even walking through them was difficult, let alone driving.

Very pleased with the Tesla’s behavior on snowy roads and maneuvering in snowdrifts. Here, nobody uses winter tires (the snowy season is very short), and everyone has “all-season” tires on their wheels.

On the highway, there’s a lot of snow removal equipment, and overall the highways are in pretty good condition – the driving is very predictable, with no skidding. But as soon as you try to turn off onto a smaller road, that’s where the test for the all-wheel drive and clearance starts. Again, no surprises at all – it passes like a tank wherever needed. 627 “horses”, dynamically distributed across four wheels, apparently helps.

Jet Trails as Weather Predictors: A Phenomenon of High Altitude Humidity | January 24 2026, 02:34

Walking with Yuki, I see across the sky a very distinct and narrow streak clearly (apparently, an airplane had passed by), and usually a contrail disappears quite quickly, but today it is unusually sharp and long.

I started to investigate and it turns out this is a reliable indicator of changing weather, specifically the arrival of snow or rain: as we are actually expecting a sudden knee-deep snowfall tomorrow. In short: the airplane trail acts as an indicator of humidity at high altitudes.

Here’s how it works:

For a contrail not to evaporate but to start “smearing”, the air at an altitude of 8–10 kilometers must be very humid (saturated with moisture). If the air is dry, the ice crystals from the engine quickly turn into invisible vapor (sublimate). If the air is moist, the crystals have nowhere to evaporate. Instead, they start attracting extra moisture from the surrounding environment and grow. High humidity at high altitudes is a sure sign of an approaching warm atmospheric front.

Navigating the Future: Embracing Earth’s Magnetic Field as a GPS Alternative | January 10 2026, 17:41

I learned today that there is and is actively used a technology for navigation using the Earth’s magnetic field. It is used as a replacement or an extension of GPS.

For example, there is the Scandinavian ferry Express 5 of Bornholmslinjen, which insures against GPS problems (which do happen) by using MagNav navigation. Unlike GPS, the Earth’s magnetic field cannot be jammed or spoofed—it simply exists. The ferry follows the same route, and generally, navigation could even be achieved through household fishing sonars.

But there are a few startups that use this technology for indoor navigation, where GPS signals cannot reach. It’s claimed that the navigation accuracy is within 1 meter. That’s more interesting.

GiPStech, Oriient, Mapsted.

The basis of this technology is a process called magnetic fingerprinting. Engineers or mapping robots walk through a building with a smartphone, recording unique distortions of the magnetic field at every point. These distortions are created by the steel frame of the building, rebar in the walls, and large electrical equipment. A database is formed where each coordinate (x, y, z) corresponds to its unique magnetic field vector (intensity, inclination, deviation).

The collected data is uploaded to the cloud platform of the provider company. There, they undergo noise cleaning and are “stitched” together with the digital floor plan. When a user walks through a shopping center, their smartphone reads data from the built-in magnetometer in real-time. Special software (SDK) compares the current readings with those stored in the database. For accuracy to be within 1–2 meters, the system relies not only on magnets. It uses sensor fusion—combining data from the magnetic field with inertial sensors (accelerometer counts steps, gyroscope determines turns) and sometimes Wi-Fi/Bluetooth signals for rough localization.

This technology is certainly being actively implemented for drones. The main technical difficulty there is dealing with their own interference and considering that the magnetic field changes, requiring constant map updates. Electrics, engines create strong magnetic fields, which “drown out” the natural background of the Earth. However, various filtering algorithms (including neural networks) are used, which in real-time “subtract” motor interference from the overall sensor readings. From what I understand, at high altitudes (kilometers), the magnetic field is more “smooth”, therefore the accuracy is lower (about 1–5 km). But if several drones fly together and exchange signals, overall they can provide very good accuracy each. Additionally, a group of drones can measure the gradient (rate of change) of the magnetic field in space, tying location not to absolute values, but to relative ones. Essentially, using a group of drones turns the navigation system from a set of individual receivers into a distributed phased array antenna, capable of filtering global interferences and working with much weaker useful signals. Considering that small drones capable of staying airborne for long periods can be released into the air by the hundreds (and cost pennies), this is a quite promising area for military.

There’s an interesting startup, Zerokey. They release QUANTUM RTLS 2.0. This device provides spatial accuracy to 1.5mm. It’s used in production, for example. Their video shows a “watch” on a worker’s hand that monitors the correctness of assembling something on a table. Here, the principle is ultrasonic, and it’s understandable that these “watches” are paired with stationary sensors and further multilateration.
