Max Erik Tegmark (born 5 May 1967) is a Swedish-American cosmologist. Tegmark is a professor at the Massachusetts Institute of Technology and is the scientific director of the Foundational Questions Institute.
Tegmark was born as Max Shapiro in Sweden, son of Karin Tegmark and Harold S. Shapiro, studied at the Royal Institute of Technology in Stockholm, and later received his Ph.D. from the University of California, Berkeley. After having worked at the University of Pennsylvania, he is now at the Massachusetts Institute of Technology. While still in high-school, Max wrote, and sold commercially, together with school buddy Magnus Bodin a word processor written in pure machine code  for the Swedish eight-bit computer ABC 80.
His research has focused on cosmology, combining theoretical work with new measurements to place constraints on cosmological models and their free parameters, often in collaboration with experimentalists. He has over 200 publications, of which nine have been cited over 500 times. He has developed data analysis tools based on information theory and applied them to Cosmic Microwave Background experiments such as COBE, QMAP, and WMAP, and to galaxy redshift surveys such as the Las Campanas Redshift Survey, the 2dF Survey and the Sloan Digital Sky Survey.
With Daniel Eisenstein and Wayne Hu, he introduced the idea of using Baryon Acoustic Oscillations as a Standard Ruler.[non-primary source needed] With Angelica de Oliveira-Costa and Andrew Hamilton, he discovered the anomalous multipole alignment in the WMAP data sometimes referred to as the "axis of evil".[non-primary source needed]
Tegmark has also formulated the "Ultimate ensemble theory of everything", whose only postulate is that "all structures that exist mathematically exist also physically". This simple theory, with no free parameters at all, suggests that in those structures complex enough to contain self-aware substructures (SASs), these SASs will subjectively perceive themselves as existing in a physically "real" world. This idea is formalized as the "Mathematical universe hypothesis".
Tegmark was elected Fellow of the American Physical Society in 2012 for, according to the citation, "his contributions to cosmology, including precision measurements from cosmic microwave background and galaxy clustering data, tests of inflation and gravitation theories, and the development of a new technology for low-frequency radio interferometry".
He was married to astrophysicist Angelica de Oliveira-Costa in 1997, and divorced in 2009. They have two sons.
In the media
- In 2006, Tegmark was one of fifty scientists interviewed by New Scientist about their predictions for the future. His prediction: "In 50 years, you may be able to buy T-shirts on which are printed equations describing the unified laws of our universes."
- Tegmark appears in the documentary Parallel Worlds, Parallel Lives in which he is interviewed by Mark Oliver Everett, son of the founder of the many-worlds interpretation of quantum mechanics, Hugh Everett.
- Tegmark also appears in "Who's afraid of a big black hole?", "What time is it?", "To Infinity and Beyond", "Is Everything We Know About The Universe Wrong?" and "What is Reality?", all part of the BBC's Horizon scientific series of programmes.
- He appears in several episodes of Sci Fi Science: Physics of the Impossible, an American documentary television series on Science which first aired in the United States on December 1, 2009. The series is hosted by theoretical physicist Michio Kaku.
