Orbits

To celebrate New Year’s Day, I wrote a post about the earth’s revolution around the sun amongst other things.

Why do planets / moons orbit but not crash into each because of the mass differential and gravity?

The trick to staying up is sideways momentum and speed. You see orbits like when you throw a ball, but of course it will eventually hit the ground. The reason the moon continues in orbit is because of speed. If the ball is thrown fast enough and had no air slowing it down, then it would orbit forever.
The moon orbits every 27 days at 3600 kilometres an hour. The only way it would crash into earth is to slow down.

Generations

What is Sovietizing the Science called?

Lysenkoism was named after the Soviet bioligist Trofim Lysenko’s influence upon science and agriculture in the first half of the 20th Century and his rejection of natural selection. It illustrated the disastrous intrusion of politics and ideology into the affairs of science. Lysenkoism led to repression and persecution of scientists who dared oppose Lysenko’s pseudo-scientific doctrines. COVID 19 ring any bells? His idea if given the proper conditions, is that all organisms have the capacity to do anything which had attractive parallels to social philosophies of Karl Marx – ‘that man was largely a product of his own will’.
