Giorgio Parisi (born August 4, 1948) is a famous Italian theoretical physicist. He studies how things work in the universe, from tiny particles to large groups of animals. He is especially known for his work on complex systems, which are things made of many parts that interact in complicated ways, like a flock of birds or the Earth's climate. In 2021, he won the Nobel Prize in Physics for his amazing discoveries about how disorder and tiny changes affect physical systems, from atoms to planets.
His important work includes understanding how particles behave inside atoms, solving puzzles about spin glasses (special magnetic materials), and describing how surfaces grow unevenly. He also studied how large groups of animals, like flocks of birds, move together.

Early Life and Education
Giorgio Parisi was born in Rome, Italy, on August 4, 1948. He loved learning about how the world works. He went to the University of Rome La Sapienza and earned his degree in 1970. His teacher and mentor there was a well-known physicist named Nicola Cabibbo.
A Career in Physics
After finishing his studies, Giorgio Parisi began his journey as a researcher.
- From 1971 to 1981, he worked at the Laboratori Nazionali di Frascati, a national research lab in Italy.
- He also spent time as a visiting scientist at famous universities and institutes around the world, including Columbia University in the United States (1973–1974), the Institut des Hautes Études Scientifiques (1976–1977), and the École Normale Supérieure (1977–1978) in France.
- From 1981 to 1992, he was a full professor of Theoretical Physics at the University of Rome Tor Vergata.
- Today, he is a professor of Quantum Theories at the Sapienza University of Rome.
- From 2018 to 2021, he was the president of the Accademia dei Lincei, which is one of Italy's oldest and most respected scientific academies.
- In 2023, he became a Fellow of The World Academy of Sciences, an honor given to top scientists from developing countries.
Exploring the World of Physics
Giorgio Parisi's research covers many different areas of physics. He is like a detective who tries to figure out the hidden rules of the universe.
Understanding Complex Systems
One of his main interests is statistical physics, especially how disordered systems behave. Imagine a jar full of marbles, but some are sticky and some are smooth, and they are all mixed up. This is a bit like a disordered system. Parisi found ways to understand these complex systems, even when they seem messy. His work on spin glasses is a great example. Spin glasses are materials where tiny magnets are arranged in a random, "frustrated" way, making them hard to understand. Parisi's methods helped solve these puzzles.
Particles and Forces
He also made important contributions to elementary particle physics, which studies the smallest building blocks of matter.
- With another physicist, Guido Altarelli, he developed equations (called the Altarelli–Parisi equations) that help explain how quarks and gluons (tiny particles inside atoms) behave.
- He also worked on the Kardar–Parisi–Zhang equation, which describes how surfaces grow in a rough, uneven way, like how a crystal forms or how a fire spreads.
Nature's Patterns
Parisi also looked at how things move in nature.
- He studied fluid dynamics, which is about how liquids and gases flow. He helped explain why turbulent flows (like swirling water in a river) can be so unpredictable.
- He also researched the collective motion of animals, like how huge flocks of birds fly together without crashing. This is another example of a complex system.
- He even helped introduce the idea of stochastic resonance to understand how small, random changes can sometimes help a system respond better to signals, like in climate change studies.
Awards and Honors
Giorgio Parisi has received many important awards for his groundbreaking work.
- Boltzmann Medal (1992): This award recognized his fundamental work in statistical physics, especially his solution for understanding spin glasses.
- Dirac Medal (1999): He received this for his deep and original contributions to many areas of physics, from particle physics to understanding disordered systems.
- Enrico Fermi Prize (2002): This prize honored his work in field theory and statistical mechanics, particularly his discoveries about disordered systems.
- Dannie Heineman Prize for Mathematical Physics (2005): He was recognized for his important discoveries in particle physics, quantum field theory, and statistical mechanics, especially for his work on spin glasses.
- Microsoft Award (2007): This award highlighted his outstanding contributions to particle physics and statistical mechanics, especially his work on phase transitions and spin glasses. It also noted his use of computers to help his research.
- Lagrange Prize (2009): This prize is given to scientists who have contributed the most to the science of complexity.
- Max Planck Medal (2011): He received this for his significant contributions to theoretical particle physics and statistical physics, especially for systems with "frozen disorder" like spin glasses.
- Lars Onsager Prize (2016): This award was for his innovative ideas using spin glass concepts to solve difficult computer problems.
- Pomeranchuk Prize (2018): He was honored for his excellent results in quantum field theory, statistical mechanics, and particle theory.
- Wolf Prize (2021): This prestigious award recognized him as one of the most creative and influential theoretical physicists in recent decades. His work has had a huge impact on many areas of science.
- Nobel Prize in Physics (2021): This is his most famous award. He shared it with two other scientists for his discovery of how disorder and tiny changes (fluctuations) interact in physical systems, from the smallest atoms to the largest planets.
He is also a foreign member of important scientific groups like the French Academy of Sciences and the United States National Academy of Sciences.
Activism for Science
Since 2016, Giorgio Parisi has been a leader in a movement called "Salviamo la Ricerca Italiana" (Let's Save Italian Research). He works to encourage the Italian and European governments to provide more funding for basic scientific research. He believes that supporting science is very important for the future.
