This book delves into finite mathematics and its application in physics, particularly quantum theory. It is shown that quantum theory based on finite mathematics is more general than standard quantum theory, whilst finite mathematics is itself more general than standard mathematics.As a consequence, the mathematics describing nature at the most fundamental level involves only a finite number of numbers while the notions of limit, infinite/infinitesimal and continuity are needed only in calculations that describe nature approximately. It is also shown that the concepts of particle and antiparticle are likewise approximate notions, valid only in special situations, and that the electric charge and baryon- and lepton quantum numbers can be only approximately conserved.
Felix Grigorievich Lev (Russian: Феликс Григорьевич Лев) was a Soviet writer and poet. He is best known as the author of children's books on nature and popular science works for children and youth.
Felix Grigorievich was born in 1932 in Moscow, into a family of engineers. From 1933 to 1939 the family lived in Gorky; in 1940 she returned to Moscow. During the Great Patriotic War, Felix was evacuated to Chelyabinsk.
In 1954 he graduated from the Institute of Engineers of Geodesy, Aerial Photography and Cartography with a degree in astronomy-geodesist engineer. After graduating from the institute, he worked for three years as an engineer-geodesist in the Pechora, Northern Urals, in the Vologda region.
