About the book: 1971 / This book contains conjectural material: how the frivolous Archimedes and Pythagoras, Newtons and Galileos treated their sciences (with all due respect), Cyril and Methodius. In the intervals between discoveries that immortalized their names. The author does not claim an academic degree, but a certain degree of reader attention. And for understanding. And smiles - in those places where it is impossible to do without them.
