motion machine were made by the following inventors back in the 12th century in 1775, the french academy of sciencesal motion machines, issues a special decree not to consider such projects. i drive them complete nonsense. well, here, after more than 200 years, we have to admit that the idea of creating a perpetual motion machine is also eternal of course ovechkin i would not waste time like napoleon, using if it were n't for my fear, your violent ingenuity and so before you is a scheme of a perpetual motion machine. oh , it's clear. here it is a magnet inclined plane, chute hole iron ball. further everything is clear. so the class is divided into two parts, some inventors of perpetual motion machines and other technical experts. the task of the experts. quiet. quietly, the purpose of the lesson, independently, you formulated the scientific rationale for the fundamental impossibility of implementing a perpetual motion machine. i am something i doubt that it is fundamentally unlucky to take, for example, the cycle in nature, also on the principle of perpetual motion. the material fails on diesel
