Born and raised in Germany, Ulrich Mohrhoff joined the Sri Aurobindo International Centre of Education (SAICE), Pondicherry (India), a department of the Sri Aurobindo Ashram as an undergraduate student in 1972. From 1974 to 1978 he studied physics at the University of Göttingen, Germany, and at the Indian Institute of Science in Bangalore (India). Since settling in Pondicherry in 1978, he pursues independent research in the foundations of physics and at the interface of contemporary physics and Indian philosophy/psychology. In 1996 he began publishing original research in various peer-reviewed journals. Since 2000 he teaches a philosophically oriented course of contemporary physics to higher secondary and undergraduate students at the SAICE. He was the founding and managing editor of AntiMatters (ISSN 0973-8606), a quarterly open-access e-journal addressing issues in science and the humanities from non-materialistic perspectives, which appeared from August 2007 till November 2009. His textbook The World According to Quantum Mechanics: Why the Laws of Physics Make Perfect Sense After All, was published on April 7, 2011 by World Scientific Publishing.
