Second Law Of Motion Quotes (1 quote)
Inequality is the cause of all local movements. There is no rest without equality.
From Codex Atlanticus, folio 288 back a. In Edward McCurdy, The Notebooks of Leonardo Da Vinci (1939, 1958), Vol. 1, 89. [Compare with Newton’s Laws of Motion. Da Vinci died in 1519; Newton was born over 120 years later. Webmaster, despite much time looking, has not yet found the corresponding quote in the John Paul Richter translation. Can you help? —Webmaster]

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
