The World as Space and Time

This is the first English translation of the book The World as Space and Time written by the great Russian physicist Alexander Friedmann who first showed in 1922 that Einstein's equations have solutions that describe a non-stationary Universe (later the experimental evidence did confirm that the Universe is expanding). The original Russian publication was in 1923.The book is one of the first introductions to the spacetime physics of the theory of relativity for a wider audience. Friedmann had succeeded in both making the book accessible to non-experts and providing rigorous explanations.

Vesselin Petkov received a graduate degree in physics from SofiaUniversity, a doctorate in philosophy from the Institute forPhilosophical Research of the Bulgarian Academy of Sciences, and adoctorate in physics from Concordia University in Montreal. He taught at Sofia University and Concordia University, and also had a stint at thePhysics Department of the Johannes Kepler University of Linz, Austria,before coming to Montreal in 1990.

Vesselin Petkov is one of thefounding members and the current director of the Minkowski Institute(minkowskiinstitute.org/) whose most distinct feature is the employmentof a research strategy based on the successful methods behind thegreatest discoveries in physics. In this sense the Minkowski Instituteis without a counterpart in the world.
