En mathématiques, les idées les plus simples peuvent aussi être les plus déroutantes. Prenons l’exemple de l’addition. C’est une opération très simple : l’un des premiers faits mathématiques que nous apprenons est que 1 + 1 = 2. Mais les mathématiciens se posent encore de nombreuses questions sur les structures que l’addition peut engendrer et les richesses qu’elle recèle.

11 hours agoYou might wonder, at some point today, what’s going on in another person’s mind. You may compliment someone’s great mind, or say they are out of their mind. You may even try to expand or free your own mind. But what is a mind? Defining the concept is a surprisingly slippery task. The mind is the seat …

Boltzmann could already show that Newton’s laws of motion give rise to his mesoscopic equation, so long as one crucial assumption holds true: that the particles in the gas move more or less independently of each other. That is, it must be very rare for a particular pair of molecules to collide with each other multiple times. But Boltzmann could not definitively demonstrate that this assumption was true.

The simplest ideas in mathematics can also be the most perplexing. Take addition. It’s a straightforward operation: One of the first mathematical truths we learn is that 1 plus 1 equals 2. But mathematicians still have many unanswered questions about the kinds of patterns that addition can give rise to. “This is one of the most basic things you can do,” said Benjamin Bedert, a graduate student at the University of Oxford.

To certain mathematicians — Sarnak among them — the Alon-Boppana bound was an entrancing challenge. Could they construct graphs, they wondered, that reached this limit? In a landmark paper published in 1988, Sarnak, Alexander Lubotzky and Ralph Phillips figured out how to. Using a highly technical result in number theory by the Indian math prodigy Srinivasa Ramanujan, Sarnak and his collaborators produced regular graphs that achieved the Alon-Boppana bound.

The original version of this story appeared in Quanta Magazine. In 2003, a German graduate student named Britta Späth encountered the McKay conjecture, one of the biggest open problems in the mathematical realm known as group theory. At first her goals were relatively modest: She hoped to prove a theorem or two that would make incremental progress on the problem, as many other mathematicians had done before her. But over the years, she was drawn back to it, again and again.
