A Vancouverite is awarded the Mathematicians' Holy Grail


Comment: John Damellos
What an honor for a fellow Vancouverite and UBC Alumni!!! 
Dr. Robert Langlands, was born in 1936 in New Westminster, just outside Vancouver and earned his bachelor's and master's degree in mathematics from the University of British Columbia. Then, he earned a Ph.D. from Yale University and went on to become an instructor at Princeton. He is now 81 years of age, an emeritus professor at the Institute for Advanced Study at Princeton University, and today it was announced that he won the Abel Prize, a prestigious mathematics prize that honors a lifetime of groundbreaking work.


According to a statement from the organizers of the prize, Langlands, won the prize for work in which he found deep connections between two seemingly disparate areas of mathematics: number theory and harmonic analysis.

Inattentive student but with HUGE IQ tests...

In a 2010 interview with University of British Columbia graduate student Farzin Barekat, Langlands had expressed his early dislike of academia. "School, except that it was a place frequented by girls and my friends, meant little to me... "I was probably the despair of the teachers, who, perhaps from the results of IQ tests, were aware that I had considerable untapped academic potential, from which I refused to profit." According to a biography of Langlands on the Abel Prize website, he didn't even plan to go to a university until a teacher told him it would be a "betrayal of his God-given talents" if he didn't go! So, he listened to his teacher and went to College, and instead of becoming a building-supply store owner, he won the Mathematicians' Holy Grail. 

As Live Science reports, it was at Princeton that Langlands developed his breakthrough idea

"It was at Princeton, on a school break, that the 30-year-old instructor had the insight that would shape the course of his mathematical life. When he returned to school, he mentioned his idea to the legendary mathematician André Weil when they bumped into each other in a hallway, and Weil told Langlands to write up his thoughts in a letter.

"If you are willing to read it as pure speculation, I would appreciate that," Langlands wrote to Weil. "If not ­— I am sure you have a wastebasket handy."

What followed was a 17-page letter that revealed secret connections between very different areas of mathematics.

In the letter, Langlands described a way to extend some of Carl Friedrich Gauss' pioneering work on prime numbers. Number theorists before Gauss had noticed a hidden relationship among primes: that all the primes that can be formulated as the sum of two squares (for instance, 2^2 + 1^2 = 5 or 3^2+2^2 = 13) have a remainder of 1 when divided by 4, but didn't know if it held true in all cases Quanta magazine reported. Gauss proved this idea in what's now known as the quadratic reciprocity law.

Langlands took Gauss' work and showed that the prime numbers that can be expressed as the sum of numbers raised to the third or fourth power (such as 1^3+2^3+4^3=73) can be tied to the distant mathematical realm of harmonic analysis. (This kind of analysis includes Fourier transforms, a mainstay tool used by scientists and engineers to analyze signals that have a periodic nature, such as sound waves or electromagnetic radiation spectra.)

Langlands showed that these two separate branches of mathematics can be directly related by using a special mathematical approach, a decoder ring of sorts, that became known as functoriality.

Langlands' work became so critical to math that his findings lured hundreds of other mathematicians into a new field of study that eventually became known as the Langlands program. And in 1995, when Andrew Wiles, a British mathematician, finally proved Fermat's last theorem, one of the most famous mathematical conjectures in history, he relied on Langlands' theory for a critical piece of the proof. (That theorem posits that there is no solution to the equation a^n+b^n=c^n for any n greater than 2 if a, b and c are all different numbers.)

Langlands will receive 6 million Norwegian krone (approximately $775,000) from Norway's King Harald V in a ceremony in Oslo, Norway, on May 22, according to the Abel Prize organizers."
