So whatever problem you have in your knowledge, and suddenly you think, oh, that doesn't fit, there is a problem, and so on, what do you do? You stop projecting your attention onto the set of theoretical object you have, and you come back where you are. Where are you? In the laboratory observing dots on the screen. 00:24:54 And then you think, is my picture adequate to the dots I'm seeing now in the screen? That's what occurs at each scientific revolution. Suddenly, if things, scientists say, poof, finished, all this theory, I have to think everything again from what is given to me.

there was, essentially, no “scientific revolution” during the Renaissance, only a continuation of work that was already happening in the “dark ages” of medieval thought.
