Our universe can be described mathematically by a simple model developed in 1922 at Petrograd (St Petersburg) by Alexander Friedmann (1888–1925), who predicted that the whole universe would expand and evolve with time before there was any observational evidence. He was an outstanding Soviet physicist, and this vivid 1993 biography is set in a wide historical background. The book is a window on the school and university years, military service, teaching and research during a seminal period of Soviet history. The authors include unique archival material, such as Friedmann's letters from the Front, as well as contemporary records and reminiscences of colleagues. There is a detailed treatment of his work in Theoretical Cosmology (1922–1924), set in the context of the organization of Soviet science at the time.

Osserman erzählt lebendig und anschaulich eine Geschichte der Geometrie, von der Bestimmung der Erdgestalt und -größe durch die alten Griechen über das Problem der Kartierung der Weltkugel bis hin zur gekrümmten Raumzeit, den Fraktalen und Buckyballs. Viele wird überraschen, dass in der Mathematik nicht nur analytisches Denken zählt, sondern dass Imagination, Phantasie und Kreativität viel wichtiger sind. Dies und die Schönheit der Mathematik schlagen die Brücke zur Bildenden Kunst und Literatur, so nimmt Dante in seiner Göttlichen Komödie das Riemannsche Universum vorweg - zudem besteht eine frappante Analogie zwischen Dantes Göttlichem Licht und dem Urknall. Auch menschliche Aspekte kommen nicht zu kurz: Euler, Gauß und Riemann werden zum Beispiel als mathematische Entsprechungen von Bach, Beethoven und Brahms vorgestellt.

"In preparing this remarkable book, Ernest Hook persuaded an eminent group of scientists, historians, sociologists and philosophers to focus on the problem: why are some discoveries rejected at a particular time but later seen to be valid? The interaction of these experts did not produce agreement on 'prematurity' in science but something more valuable: a collection of fascinating papers, many of them based on new research and analysis, which sometimes forced the author to revise a previously-held opinion. The book should be enthusiastically welcomed by all readers who are interested in how science works."—Stephen G. Brush, co-author of Physics, The Human Adventure: From copernicus to Einstein and Beyond "Prematurity and Scientific Discovery contains interesting and insightful papers by numerous well-known scientists and scholars. It will be of wide interest, not only to science studies scholars but also to working scientists and to science-literate general readers."—Thomas Nickles, editor of Scientific Discovery, Logic, and Rationality

This book presents a high-level study of cosmology with interacting dark energy and no additional fields. It is known that dark energy is not necessarily uniform when other sources of gravity are present: interaction with matter leads to its variation in space and time. The present text studies the cosmological implications of this circumstance by analyzing cosmological models in which the dark energy density interacts with matter and thus changes with the time. The book also includes a translation of a seminal article about the remarkable life and work of E.B. Gliner, the first person to suggest the concept of dark energy in 1965.

This is the first English translation of the book The World as Space and Time (Мир как пространство и время) 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.
