Alex Eskin , a mathematician at the University of Chicago , has bring home the bacon the $ 3 million 2019 Breakthrough Prize in Mathematics .
The Breakthrough Prizes were found in 2013 bya mathematical group of tech billionaires(as well asmultihundred millionaireAnne Wojcicki , co - founder and CEO of genomics and biotech company 23andMe ) . The prizes are awarded each year to investigator in math , fundamental aperient and the life sciences . Past winners decide who will win in each family .
What happens when you put a candle in a room of perfect mirrors?
Eskin , a 54 - twelvemonth - old American mathematician born in Moscow , receive the award for what the prize commission describe as " revolutionary uncovering in the dynamics and geometry of moduli quad of Abelian differentials , " specifically calling out his 2013paperwith mathematicianMaryam Mirzakhanithat proved their " magic wand theorem . "

Mirzakhani , a former Stanford University professor deport in Tehran , Iran , was also famous in the universe of mathematics for her work in an area known as moduli spaces . She collaborate with Eskin on several important piece of music of this study . On Aug. 13 , 2014 , she won the Fields Medal ( the most prestigious swag in mathematics , award once every four geezerhood totwo , three or four mathematiciansunder age 40 ) . She was the first woman to win the prize , and no woman has won it since . She died of boob Crab onJuly 14 , 2017 , at age 40 .
So , what does the magic verge theorem do ?
" It ’s useful in several different areas of maths , " Eskin told Live Sciencet , noting that the idea of the wand is a metaphor for how useful the theorem is , not a physical object or chassis . " There is no wand . "
" The theorem itself which we proved is in an area of math that is not light to explicate , " he said . " It take me hours and hours to excuse to math Ph . D.s that work in different subfields . "
However , he added , " There is a consequence [ of proving it ] which anyone can sympathize . "
Imagine a room made out of perfect mirrors , Eskin said . It does n’t have to be a rectangle ; any weird polygonal shape will do . ( Just verify the angles of the unlike walls can be expressed as ratios of whole numbers . For model , 95 grade or two - thirds of a arcdegree would make , but private investigator degrees would not . )
Now commit a wax light in the middle of the elbow room , one that beam light in every centering . As the calorie-free bounces around the different turning point , will it always illume the whole room ? Or will it miss some smear ? A side effect of proving the witching verge theorem , Eskin said , is that it once and for all answers this old question .
" There are no dingy blot , " he say . " Every period in the elbow room is lit . "

Eskin suppose he first became interested in the ideas behind the witching wand theorem as a alum scholarly person doing research refer to a serial of cogent evidence known as Ratner ’s theorems , which mathematician Marina Ratner proved in the former 1990s . ( Ratner , a former University of California , Berkeley mathematician , perish one week before Mirzakhani , on July 7 , 2017 , at age 78 . )
Ratner ’s theorems lot with homogeneous spaces , " where every point is like every other point , such as the open of a sphere , " Eskin said . Eskin wondered whether Ratner ’s ideas could be transmit forward into modulus place , where not all the points are the same .
" I in reality got obsessed with this problem , " Eskin said . " I had to work on other affair because I was young , and you have to publish [ enquiry ] to get charter . But I was always think about this job . "
Still , years turn over before he was able to make pregnant progress .
" Eventually , I meet Maryam Mirzakhani , " Eskin say . " She ’s a lot immature than I am — I met her when she was a [ inquiry fellow at Princeton University ] — and we had exchangeable research interest , and we lead off collaborate for a while . And she ’s very much not concerned in going after the low - hanging yield . She wanted to sour on the unmanageable problems . So , our projects got more and more challenging . "
Still , they did n’t now jump plugging away at the problem that would help direct to Mirzakhani ’s Fields Medal and Eskin ’s Breakthrough Prize .
" This was kind of the biggest problem in our whole area , " he said . " She knew I was thinking about it , and I knew she was believe about it . But we never speak about it . And this went on for a couple of years , and then we just decide to join forces . "
Eskin compared what took place over the next five years to a spate - climbing expedition , noting that he ’s not the first mathematician to describe a theoretical research project this means .
An important early milepost , he said , was a January 2009 newspaper by French mathematician Yves Benoist and Jean - François Quint in the journalComptes Rendus Mathématique . It was in a different area of mathematics , but it turned out to be relevant in some important ways . That paper led Eskin and Mirzakhani to the first itinerary up the stack .
" For two class then , we were climbing it , wee firm progress , " Eskin say . " And finally , we got to a seat where we could see the top . But we hit a ravine , and we could n’t cross that ravine . "

" We were basically stick for a class and a half , " he said . " We were seek all variety of ways to go at this and basically made dead no progress . "
At some point , though , they decided to check trying to cross the ravine .
" We found a way to mount the other side of the tidy sum , " he said .
Their new feeler no longer started from the 2009 Gallic paper but or else leaned hard on earlier work by Israeli mathematician and 2010 Fields Medal winner Elon Lindenstrauss .
" Using this other oeuvre , die around the back , we could n’t progress to the top either , " Eskin said . " But we kind of found enough material that we could establish a nosepiece over the ravine . "
That " textile " was a series of modest test copy , made while climbing that back road , that allowed the original itinerary to become passable .
" From there , it take us another two years to write it down and ensure it all worked , " Eskin pronounce .
As for what he intends to do with the booty money , Eskin said , " You hump , it ’s kind of arresting . I have n’t decided yet . "
Like retiring winners , he intend to donate a significant centre to an International Mathematical Unionfellowshipfor graduate bookman pursuing doctorates in developing country . As for the rest , he said , " I just have no idea . "
" One of the thing about working in math is that the heights are very high and the lows are very low-toned , " Eskin said . " It ’s very frustrating , because for a prospicient time , you essentially can make no progress . At some point , you ’ve drop five geezerhood lick on a project , and you never know if it ’s going to work or not … It ’s a vainglorious part of your biography invest in this . There ’s always a with child hypothesis you ’ll come out of it with nothing … You need a circle of emotional constancy to keep on run low . "
