Slavic Quotes (1 quote)
Copernicus and Lobatchewsky were both of Slavic origin. Each of them has brought about a revolution in scientific ideas so great that it can only be compared with that wrought by the other. And the reason of the transcendent importance of these two changes is that they are changes in the conception of the Cosmos. … Now the enormous effect of the Copernican system, and of the astronomical discoveries that have followed it, is … the change effected by Copernicus in the idea of the universe. But there was left another to be made. For the laws of space and motion…. So, you see, there is a real parallel between the work of Copernicus and … the work of Lobatchewsky.

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.
