Our universe might be defined mathematically through an easy version constructed in 1922 at Petrograd (St. Petersburg) by means of Alexander Friedmann (1888-1925). with no the good thing about observational facts, Friedmann expected that the total universe might extend and evolve with time. This impressive prediction used to be proven seven years later via Edwin Hubble. Its originator, regrettably did not dwell to relish this triumph. This shiny biography of a great scientist units his existence and paintings opposed to a large backdrop of the background of cosmological reviews and its significant gamers, similar to Einstein and others.

Example text

This letter is interesting right away for the place where it was posted. Its name will not mean anything to most readers. In the recent (Russian) edition of The Dictionary of Geography (1986) the town of Tim is not mentioned, though can be found on the little map of the Kursk Region placed in the dictionary. The town is 60 km east of the city of Kursk, and even today it is not on the railroad. The very detailed encyclopedia of Brockhaus and Efron (vol. " In 1907, its population was 7,380 (3,512 men and 3,868 women).

And he didn't part with his umbrella when he was in the Kursk Region, in Tim, where everything was lit with the sun in the summer. There was a young man named Andrei Borisyak, nice and cheerful - always the life and soul of the party. Incidentally, he discovered a supernova one day, for which Nicholas II granted him a telescope. Boris wrote verses and drew well. I can still see his friendly caricature: Friedmann walking with a bowler hat on and an umbrella. Friedmann was full of contradictions: fanaticism, for instance, combined with unusual pragmatism.

There is also a more detailed review of Lucas de Pesloiian's Abel: his Life and Work published in Paris. Like the author, Friedmann writes with great sympathy about the hard fate of this outstanding Norwegian mathematician, who was not understood even by his great contemporaries Cauchy, Legendre and Gauss ("It is terrifying to read about the loneliness that oppressed Abel," wrote Friedmann). " And Abel was already a university professor! The article about Abel's biography is written by a mature person, a perceptive and discriminating reader.
