Заглавие: Измерване на гравитационни вълни II. Автор: Вълков, Лазар Марков; Valkov, Lazar Markov; Марков, Марко Николов; Marcov, Marco Nikolov Дата: 1995 Резюме: There is a complete harmony between Planck S axiomatic method setted in the natural measurement system and the charge-mass method (CMM). As a result one obtained new Plancks ’ gravity quantities, namely supergravitational force and supergravitational acceleration which determine universe’s dynamics. We established that the second constant ... Библиотека:

Заглавие: Измерване на гравитационни вълни I. Автор: Вълков, Лазар Марков; Valkov, Lazar Markov; Марков, Марко Николов; Marcov, Marco Nikolov Дата: 1995 Резюме: The charge-mass method (CMM) proved to be more compregensible and more effective for indirect measuring of the characteristc gravitational parameters of the bodies than Einstein ’s dynamic-accelerating and Making’s thermic ones. CMM is in perfect harmony with Planck’s axiomatic method seted in his natural measurement system. Библиотека:
