Question: The Breakthrough Prize in Mathematics is funded by Yuri MIller and a man estimated to be worth how much money?
Context: The Breakthrough Prize in Life Sciences is a monetary award, funded by internet entrepreneurs: Mark Zuckerberg and Priscilla Chan of Facebook; Sergey Brin of Google; entrepreneur and venture capitalist Yuri Milner; and Anne Wojcicki, one of the founders of the genetics company 23andMe.  The Chairman of the Board is Arthur D. Levinson of Apple. Breakthrough Initiatives is a program founded in 2015 and funded by Yuri Milner to search for extraterrestrial intelligence over a span of at least 10 years.  The program is divided into multiple projects.  Breakthrough Listen will comprise an effort to search over 1,000,000 stars for artificial radio or laser signals.  A parallel project called Breakthrough Message is an effort to create a message "representative of humanity and planet Earth".  The project Breakthrough Starshot aims to send a swarm of probes to the nearest star at about 20% the speed of light.  The project Breakthrough Watch aims to identify and characterize Earth-sized, rocky planets around Alpha Centauri and other stars within 20 light years of Earth. The Breakthrough Prize in Mathematics is an award announced in 2013, and funded by Yuri Milner and Mark Zuckerberg. Terence Chi-Shen Tao FAA FRS (born 17 July 1975) is an Australian-American mathematician who has worked in various areas of mathematics.  He currently focuses on harmonic analysis, partial differential equations, algebraic combinatorics, arithmetic combinatorics, geometric combinatorics, compressed sensing and analytic number theory.  s of 2015 , he holds the James and Carol Collins chair in mathematics at the University of California, Los Angeles.  Tao was a co-recipient of the 2006 Fields Medal and the 2014 Breakthrough Prize in Mathematics. The Albany Medical Center Prize in Medicine and Biomedical Research is the United States' second highest value prize in medicine and biomedical research, awarded by the Albany Medical Center.  Among prizes for medicine worldwide, the Albany Medical Center Prize is the fourth most lucrative (after the $3 million Breakthrough Prize in Life Sciences, the $1.2 million Nobel Prize in Medicine and the $1 million Shaw Prize in life science and medicine). Demand-pull inflation is asserted to arise when aggregate demand in an economy outpaces aggregate supply.  It involves inflation rising as real gross domestic product rises and unemployment falls, as the economy moves along the Phillips curve.  This is commonly described as ""too much money chasing too few goods"".  More accurately, it should be described as involving ""too much money spent chasing too few goods"", since only money that is spent on goods and services can cause inflation.  This would not be expected to happen, unless the economy is already at a full employment level. Mark Elliot Zuckerberg ( ; born May 14, 1984) is an American computer programmer and Internet entrepreneur.  He is a co-founder of Facebook, and currently operates as its chairman and chief executive officer.  His net worth is estimated to be US$71.5 billion as of September 2017, and he is ranked by "Forbes" as the fifth richest person in the world. Maxim Lvovich Kontsevich (Russian: Макси́м Льво́вич Конце́вич ;   ; born 25 August 1964) is a Russian and French mathematician.  He is a professor at the Institut des Hautes Études Scientifiques and a distinguished professor at the University of Miami.  He received the Henri Poincaré Prize in 1997, the Fields Medal in 1998, the Crafoord Prize in 2008, the Shaw Prize and Fundamental Physics Prize in 2012, and the Breakthrough Prize in Mathematics in 2014. Make It Big () is a 2002 South Korean comedy film.  Song Seung-heon, Kim Young-jun and Kwon Sang-woo play three high school students who are startled when a bagful of money and a dead man fall on top of their car.  Once they realize just how much money is in the bag, they give up any thought of calling the police. The Breakthrough Prize is a set of international awards bestowed in three categories by Breakthrough Prize Board in recognition of scientific advance.
