Andrey Markov

1856–1922 · mathematics, probability theory, mathematical analysis
Andrey Andreyevich Markov is a Russian mathematician whose name became a symbol of stochastic dependence. Markov chains — his most famous creation — underlie the theory of random processes and are now used everywhere: from computer algorithms to modeling financial markets.

Biography

Born in Ryazan, he graduated from St. Petersburg University, where he worked all his life. A student of Pafnuty Chebyshev, Markov became one of the leaders of the St. Petersburg mathematical school. He was an academician of the St. Petersburg Academy of Sciences. He was a principled man: in protest against the excommunication of Leo Tolstoy from the church, he publicly refused all state awards.

Key discoveries

💡 Markov was an avid walker and once walked from St. Petersburg to Moscow. He first applied his famous chains to a statistical analysis of the alternation of vowels and consonants in the novel 'Eugene Onegin', proving that it is not random.
"He regarded probability as the measure of our ignorance."

Hurricane Energy Follows a Power Law
A forest fire has no "typical" size: a small grass burn and a firestorm covering thousands of hectares are part of the same phenomenon. The same goes for tropical cyclones: the energy they release over their lifetime does not cluster around some average value. Instead, it follows a power law, and this rule holds across all of Earth's oceans.

Breathing of Tropical Rains: How El Niño Phases Drive Precipitation Extremes
In 1998, the Pacific Ocean off the coast of Peru suddenly cooled, and tropical rains seemed to take a deep breath. Wet zones, where more than three meters of water falls in a year, crept westward, while dry patches, where less than two hundred millimeters accumulate, expanded off the coasts of Australia and the Americas.
Who Really Warms the Planet: The Information Trail of Climate Drivers
In a climate trial, the judge doesn't listen to who shouts loudest. He watches who whispers to whom. Nine witnesses, from carbon dioxide to cosmic rays, testified from 1984 to 2005. Their statements were recorded every month. The judge doesn't trust mere coincidences, because two witnesses might echo each other without knowing who started first.
Where Does the Boundary Lie: Algorithm Finds Groups by Gaps in Data
Imagine a border river that separates two countries. On one bank live one group of people, on the other, another.

But it is exactly where the current changes abruptly that the border becomes most noticeable.
Network Warns of El Niño a Year in Advance

How to Make Your Model Pay for Its Mistakes
A translator who jumps at every rustle in the hall starts mixing up words by the end of the meeting. Their confidence in being right grows, while their accuracy drops. That is roughly how poorly calibrated probabilistic forecasts behave: the model claims a high probability for an event, but reality disagrees.
El Niño: Forecasting from the Ocean's Memory
The ocean remembers its weather. Each month, its surface temperature forms a vast map, and if you find a similar map in the past, you can see what happened next. That is exactly how the new method for forecasting El Niño works: the warm current that, every few years, alters the climate of half the planet.
Complexity as a Precursor: Forecasting El Niño Strength a Year Ahead
Every day, the ocean in the tropical Pacific carries on a quiet conversation with itself: water temperatures are slightly higher in some places, slightly lower in others, and these patches of warmth and cold slowly drift into one another. This chatter seems random, but it hides a signal.
A Probability Map for El Niño
Imagine a map where each patch of ocean is colored with its own shade: in some places the color is saturated, meaning the future of the system is predetermined; in others it is pale, meaning the outcome depends on a random gust of wind.
Tug-of-War in the Tropics: How Seasonal Air Oscillations Drive El Niño
The tropics breathe with an annual rhythm: air temperature rises and falls, and within this breath lie two main pulses. The first pulse peaks in February and weakens in August; the second is shifted by half a year. These two pulses are not just background noise for the famous El Niño; they are its conductors.
A Month Ahead: What Machine Learning Can Do for Weather Forecasts
A farmer in Iowa looks at the calendar: plant now or wait? In a month, a heat wave might strike, or rain might set in. Forecasters throw up their hands: the two-week forecast still holds, the seasonal one is out of reach, and in between lies a gap. The atmosphere changes too quickly to remember yesterday, and the ocean is too slow to come to the rescue.
Graph Neural Networks Predict El Niño More Accurately
The warm El Niño current appears in the tropical Pacific every few years and reshuffles weather across the planet: drying fields in some places, flooding streets in others. Meteorologists have long tried to catch it early, but the ocean is too cunning: the cause hides not in a single spot but in a call-and-response between regions separated by thousands of kilometers.
Two barometers showing different weather
In 2021, two tools designed to forecast weather a year ahead showed different results. One, built on connections between temperatures at different points in the Pacific Ocean, was silent: no El Niño in 2022.

The Uneven Pulse of Time: How Irregular Measurement Rhythms Skew Conclusions and What to Do About It
Imagine an interpreter who gets distracted by every rustle in the hall. The more rustles, the more errors in the translation, even though the meaning of the speech hasn't changed.

The Ocean as a Patient: Neural Network Diagnoses Two Years Ahead
A doctor who has followed the same patient for years learns to predict flare-ups from subtle signs: a slight pallor, labored breathing, restless sleep. The ocean is just such a complex patient, only instead of a thermometer it has thousands of buoys and satellites, and instead of a medical history, seventy years of daily measurements.

Breaking Point in the Flow of Functions
A seismograph records underground tremors: the smooth line suddenly jerks and changes its character. Similarly, functional data, such as ocean temperature maps or brain signals, may shift their shape at some point. The new algorithm FSBS catches such breakpoints, even when each curve is measured at only one point and noise drowns the signal.
A Reservoir with Memory: Peeking Inside Echo State Networks
Every month, satellites and ships record the surface temperature of the ocean, and these maps build up a history of the climate. In the tropical Pacific, this history is sometimes interrupted by a warm patch, El Niño, which alters weather across the planet.

A rough sketch of a portrait: a few confident lines define the shape, but the details are not yet refined.

Echo of the Invisible Stone
In a chain of eight spins, a defect lurks — a tiny magnetic moment. The Kondo effect, known since the 1930s, makes electrons around it align into a collective screen. The material's resistance abnormally increases. But detecting such an impurity hidden deep in the structure is like finding a stone at the bottom of a dark pond.

Climate, Harvest, and Post-Harvest Conflict
On an African field, maize has just been harvested. The grain sits in sacks, and for armed groups it's a lure: something to take from farmers. But if the harvest fails, the lure disappears, and attacks become fewer. That's exactly what happens when El Niño (the warm current in the Pacific Ocean that alters weather worldwide) brings drought to Africa's farming regions.
A Sieve for El Niño: How an Algorithm Finds the Minimal Model of a Fickle Climate
Every few years, a huge pool of warm water in the western Pacific Ocean shifts eastward, like water in a bathtub when you tilt it sharply to one side. That is El Niño. But each tilt is different: sometimes the water sloshes against the shores of Peru, sometimes it stalls in the middle, sometimes it pours out in a powerful surge, and sometimes it barely creeps.
Climate Network Predicts El Niño a Year Ahead
The Pacific Ocean breathes, and that breath has a pulse. Every few years, its surface warms more than usual, bringing torrential rains to Peru and drought to Australia. This is El Niño, the warm phase of the ocean temperature oscillation.

Now, two independent methods, like two doctors examining the same symptoms, agree: no new attack in 2025.
Council of Sages: How Entropy Predicts El Niño Two Years Ahead
