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.
Interpretation
Mathematicians rely on intuition and creativity as much as on formal proof, which serves to validate their thoughts.
Gian-Carlo Rota highlights the complex nature of mathematical discovery, emphasizing that the journey involves a mixture of guesswork, analogy, and creativity. Proofs, often considered the essence of mathematics, are depicted as tools for confirming our intuitions and ideas, rather than the foundational elements of the discovery process itself.
In practice
In a lecture on mathematical creativity, this quote can illustrate the importance of intuition in problem-solving.
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.
God created infinity, and man, unable to understand infinity, had to invent finite sets.
[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.
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.
Faced with the evidence, many deniers have started to admit that global warming is real, but argue that humans have little or nothing to do with it.
All models are wrong, and increasingly you can succeed without them.
Mystics exult in mystery and want it to stay mysterious. Scientists exult in mystery for a different reason: It gives them something to do.
By venturing into space, we improve life for everyone here on Earth - scientific advances and innovations that come from this kind of research create products we use in our daily lives.
We find, therefore, under this orderly arrangement, a wonderful symmetry in the universe, and a definite relation of harmony in the motion and magnitude of the orbs, of a kind that is not possible to obtain in any other way.
The human brain has 100 billion neurons, each neuron connected to 10 thousand other neurons. Sitting on your shoulders is the most complicated object in the known universe.
