[In mathematics] There are two kinds of mistakes. There are fatal mistakes that destroy a theory, but there are also contingent ones, which are useful in testing the stability of a theory.
Interpretation
Mistakes in mathematics can either ruin a theory or help test its stability.
Gian-Carlo Rota highlights the dual nature of mistakes in mathematics: while some mistakes can be catastrophic and invalidate a theory, others can serve a constructive purpose by providing insights into the theory's robustness. This suggests that errors can be instrumental in the process of refining and strengthening mathematical concepts.
In practice
This quote could be shared during a mathematics lecture to encourage students to embrace their errors.
The apex of mathematical achievement occurs when two or more fields which were thought to be entirely unrelated turn out to be closely intertwined. Mathematicians have never decided whether they should feel excited or upset by such events.
Every lecture should state one main point and repeat it over and over, like a theme with variations. An audience is like a herd of cows, moving slowly in the direction they are being driven towards. If we make one point, we have a good chance that the audience will take the right direction; if we make several points, then the cows will scatter all over the field. The audience will lose interest and everyone will go back to the thoughts they interrupted in order to come to our lecture.
A mathematician's work is mostly a tangle of guesswork, analogy, wishful thinking and frustration, and proof, far from being the core of discovery, is more often than not a way of making sure that our minds are not playing tricks.
God created infinity, and man, unable to understand infinity, had to invent finite sets.
Mathematics is the study of analogies between analogies. All science is. Scientists want to show that things that don't look alike are really the same. That is one of their innermost Freudian motivations. In fact, that is what we mean by understanding.
People credit me for making the universe interesting when in fact the universe is inherently interesting, and I'm merely revealing that fact. I don't think I'm anything special for this to happen.
Measure what is measurable, and make measurable what is not so.
It was because of Henderson that I stayed... It was he and he alone who kept me in Toronto and in Canada. Were it not for Henderson, I believe insulin would have been a product of the United States.
Thanks to farm subsidies, the fine collaboration between agribusiness and Congress, soy, corn and cattle became king. And chicken soon joined them on the throne. It was during this period that the cycle of dietary and planetary destruction began, the thing we're only realizing just now.
We have the resources to build room for a trillion humans in this solar system, and when we have a trillion humans, we'll have a thousand Einsteins and a thousand Mozarts. It will be a way more interesting place to live.
The Earth is round, and is inhabited on all sides, is insignificantly small, and is borne through the stars.
