John Nash: the end of mathematic's beautiful mind

John Nash - www.bized.co.uk


John Forbes Nash Jr., the American mathematician immortalized in the film, A Beautiful Mind, died, along with his wife, in a car accident on May 23, 2015. He was 86 years old, and his wife Alicia Nash (nee Larde) was 82. His wife was a physics scholar, and although they divorced in 1963, they remarried in 2001.

The 2001 film, A Beautiful Mind, was “artistically” based on Nash and his paranoid schizophrenia, and based on Sylvia Nasar’s 1998 book, A Beautiful Mind. Nasar was the couple’s biographer.

Nash (1928-2015) was famous for his work at Princeton University. He was regarded as one of the greatest mathematicians of the 20th century, primarily for his work on game theory. Game theory is used to study how people act when decision making, especially in specific situations, such as conflict, stress, and collaborative teamwork. He won the Nobel Prize in Economics in 1994. The Nobel Prize was largely for his work in the fields combining mathematics and economics. There is no Nobel Prize awarded annually for mathematics (a major flaw of the Nobel Prize that has never changed throughout its 114 year history).

Awards for mathematics do occur. Nash received the John von Neumann Theory Prize in 1978 and the American Mathematical Society’s Steele Prize for a seminal contribution to research in 1999. But they are not as prestigious as the award Nash won only a week before his death. In May the Norwegian Academy of Sciences and Letters awarded the Abel Prize to Nash and his long time colleague Louis Nirenberg for their work on nonlinear partial differential equations (and linking them with the analysis of abstract geometric shapes). The Abel Prize is often called the Nobel Prize for Mathematics.


I studied Nash in my university days when I undertook mathematics and English together. I did my thesis on symbolic logic, but in my university mathematics courses I studied game theory. My love though was geometry. Few people study geometry in university these days (hence my book, Bardot’s Comet, in which the father, Leonardo Bari is a geometry professor). Nash’s work on partial differential equations (PDE) linking them to abstract geometric shapes includes parts of Albert Einstein’s work on the theory of relativity (linking curvature and gravity). PDE is the set of rules for translating, or modelling, the changes in systems with multiple dimensions – in a range of practical applications, such as financial markets, the economy, the flow of heat in a room, etc. Mathematicians are now using Nash and Nirenberg’s work on PDE to solve complex and complicated geometrical and space-related problems.

The acacia thorn trees of Kenya

There are nearly 800 species of acacia trees in the world, and most don’t have thorns. The famous "whistling thorn tree" and the Umbrella Thorn tree of Kenya are species of acacia that do have thorns, or spines. Giraffes and other herbivores normally eat thorny acacia foliage, but leave the whistling thorn alone. Usually spines are no deterrent to giraffes. Their long tongues are adapted to strip the leaves from the branches despite the thorns. The thorny acacia like dry and hot conditions. The thorns typically occur in pairs and are 5-8 centimetres (2-3 inches) long. Spines can be straight or curved depending on the species. MARTINA NICOLLS is an international aid and development consultant, and the author of:- Similar But Different in the Animal Kingdom (2017), The Shortness of Life: A Mongolian Lament (2015), Liberia’s Deadest Ends (2012), Bardot’s Comet (2011), Kashmir on a Knife-Edge (2010) and The Suda...

Shindi: the Georgian Cornelian cherry

The Cornelian cherry – shindi in Georgian – is a fruit with medicinal and decorative properties. It was grown from ancient times, according to the International Society for Horticultural Science (ISHS). It is also commonly called the European cornel. It is native to southern Europe from France to Ukraine as well as Armenia, Azerbaijan, Georgia, Iran, Turkey, Israel, Lebanon, and Syria. The Cornelian cherry tree ( Cornus mas ) can be grown in orchards, but it is often seen in the forests of Georgia where it grows up to 1,350 metres above sea level. It is a medium to large deciduous tree, growing from 5-12 metres tall. The flowers are small with four yellow petals in clusters, which flower in February and March. The Cornus mas has three botanical varieties: (1) var. typica Sanadze with cylindrical red fruits, (2) var. pyriformis Sanadze with pear-shaped red fruits, and (3) var. flava vest with yellow fruits. The fruits are oblong red drupes about 2 centimetres ...
