Russia's contribution to world science

Einstein's theory owes much of its notoriety to the so-called "twin paradox." This is probably because people want to live longer. The concept is simple: one twin stays on Earth, while the other travels at near-lightspeed to distant stars in a spaceship, and upon reaching the stars, they return to Earth using the same means and at the same speed. According to the equations of the theory of relativity, the astronaut will appear much younger than the stay-at-home twin upon their reunion.

Kant said, "In every knowledge, there is as much truth as there is mathematics." But in Kant's time, truth was understood differently than it is now. In our era, people accept as truth what provides a tactical advantage—what they pay for—and therefore, it no longer means that any article filled with formulas contains truth that is distinct from the truths about its lack of substance and the author's illiteracy. A profound thought by the mathematician Gelfand: "Logic works perfectly when an adequate language has been established by human experience, intuition, etc., but it is helpless when there is a need for this very language. The development of such a language is not a logical operation."
