Andrei Linde

род. 1948 · Cosmology, theoretical physics, quantum field theory
Soviet-American theoretical physicist, one of the creators of inflationary theory, which explains the homogeneity of the Universe right after the Big Bang. His model of chaotic inflation offered an elegant solution to many cosmological problems.

Biography

Born in 1948 in Moscow. He studied at Moscow State University, where he received his doctorate in 1975. He worked at the Lebedev Physical Institute of the USSR Academy of Sciences and then at CERN. In 1990, he emigrated to the United States, where he became a professor at Stanford University. He is known for developing new forms of inflationary scenarios. He is a recipient of many awards, including the Gruber Prize in Cosmology.

Key discoveries

💡 Linde became interested in cosmology after his teacher, Yakov Zeldovich, suggested he solve the monopole problem. It is said that when he first saw the formula for chaotic inflation, he was at his dacha in the woods and thought: 'Now I know how the Universe works.'
"He saw our Universe as only a small part of a much larger cosmos, where new inflationary regions are constantly born, and this process has no end."

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.

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.

The Universe in a Gas Trap: How to Tell Inflation from a Bounce
In the first moments after the Big Bang, the Universe underwent rapid expansion: inflation. But perhaps it was contracting before that, and then bounced. Both scenarios leave nearly identical imprints on the cosmic microwave background, and cosmologists have debated for decades which one is correct.

The Entropy of Climate Swings
You can sit on a seesaw and pump your legs, or you can just tip from one side to the other. The Pacific Ocean does both. Every few years, warm water off the coast of Peru gives way to cooler water, and rainfall patterns, winds, and entire ecosystems across half the planet reshuffle. These shifts are called El Niño and La Niña, together known as ENSO: Earth's climate seesaw.

Quantum Fog in Space: Bose-Einstein Condensates from Neutron Stars to Galaxies
In laboratories on Earth, Bose-Einstein condensates are created by cooling a cloud of atoms to billionths of a kelvin. The atoms lose their individuality and merge into a single quantum wave that behaves as one entity. But in space, such conditions are not needed: gravity itself creates deep wells where matter compresses and cools into a state of quantum fog.

Someone has thrown an invisible stone into the stellar pond of the Milky Way. The ripples spread not through water but through the motion of stars: in a region 200 by 50 parsecs across, their average vertical velocity is 7 km/s lower than that of their neighbors. The deviation is statistically significant at the 6σ level, so chance cannot explain it.
