Fields Medal

The Fields Medal is a special prize given to young mathematicians who have done important work in their field. It is awarded every four years at the International Congress of the International Mathematical Union. The medal is named after John Charles Fields, a Canadian mathematician, who helped create the award.

Many people think the Fields Medal is the highest honor a mathematician can receive. It is sometimes called the "Nobel Prize of Mathematics." The first medals were given in 1936 to Lars Ahlfors, a Finnish mathematician, and Jesse Douglas, an American mathematician. Since 1950, the medal has been awarded every four years.

In 2014, Maryam Mirzakhani, an Iranian mathematician, became the first woman to win the Fields Medal. Most winners have a doctorate in mathematics, except for two who had doctorates in physics. As of 2022, 64 people have received this prestigious award. The most recent awards were given online in 2022 from Helsinki, Finland, after plans to hold the event in Saint Petersburg, Russia were changed because of the 2022 Russian invasion of Ukraine.

Fields himself designed the medal and provided money for a cash prize, though he passed away before the award was officially created. Since 2006, the prize has included a monetary award of CA$15,000.

Conditions of the award

The Fields Medal is one of the biggest prizes in mathematics, often called the “Nobel Prize of Mathematics.” But unlike the Nobel Prize, the Fields Medal is given every four years, and the winners must be under 40 years old on January 1 of the year the medal is awarded.

The age limit was set by John Charles Fields to not only honor the great work the winners have already done, but also to encourage them to keep making new discoveries. Each person can only win the Fields Medal once, so they can’t win it again later.

List of Fields medalists

The Fields Medal is awarded every four years at the International Congress of Mathematicians to young mathematicians under the age of 40 who have made important contributions to mathematics. Special lectures are given to highlight each medalist's work. The next award will be given in Philadelphia at the 2026 congress.

The table below lists past winners and their achievements. Official descriptions are used when available, especially from 1958, 1998, and every year since 2006. For earlier years, summaries from lectures given at the congress are included.

Landmarks

The Fields Medal was first awarded in 1936 to two mathematicians: Lars Ahlfors from Finland and Jesse Douglas from the United States.

Over the years, many impressive mathematicians have received this award. In 1954, Jean-Pierre Serre became the youngest ever winner at just 27 years old. In 1990, Edward Witten was the first physicist to receive the Fields Medal. In 2014, Maryam Mirzakhani made history as the first woman and the first Iranian to win the award.

Medal

The Fields Medal is a special award for mathematicians. It was designed by Canadian sculptor R. Tait McKenzie. The medal is made of gold, is about the size of a large coin, and has a beautiful design.

On one side, you can see a picture of the ancient mathematician Archimedes along with a Latin quote that means "To surpass one's understanding and master the world." The other side shows words that say mathematicians from all over the world gave this award for excellent work. There is also a picture of Archimedes' tomb and a design showing one of his famous math ideas. The winner's name is written around the edge of the medal.

Female recipients

The Fields Medal has been awarded to two women so far. In 2014, Maryam Mirzakhani from Iran received the award. Then, in 2022, Maryna Viazovska from Ukraine also won the Fields Medal. Both were recognized for their important contributions to mathematics.

In popular culture

The Fields Medal became known to many people because of a movie from 1997, Good Will Hunting. In the film, a character named Gerald Lambeau, played by Stellan Skarsgård, is a professor at MIT who once won the Fields Medal. The movie uses the award to show how special and important it is in the world of mathematics.
