A Quote by Hermann Weyl

Logic is the hygiene the mathematician practices to keep his ideas healthy and strong. — © Hermann Weyl
Logic is the hygiene the mathematician practices to keep his ideas healthy and strong.
Keep your own house and its surroundings pure and clean. This hygiene will keep you healthy and benefit your worldly life.
A mathematician ... has no material to work with but ideas, and so his patterns are likely to last longer, since ideas wear less with time than words.
You don't have to be a genius mathematician to have a career in cyber security, but it certainly helps to be a strong mathematician.
Values are related to our emotions, just as we practice physical hygiene to preserve our physical health, we need to observe emotional hygiene to preserve a healthy mind and attitudes.
Man does not live by soap alone; and hygiene, or even health, is not much good unless you can take a healthy view of it or, better still, feel a healthy indifference to it.
Compassion suits our physical condition, whereas anger, fear and distrust are harmful to our well-being. Therefore, just as we learn the importance of physical hygiene to physical health, to ensure healthy minds, we need to learn some kind of emotional hygiene.
To me, Turing is as much of a philosopher as he is a mathematician because his ideas deal with what it means to think.
Cat-Ideas and Mouse-Ideas. We can never get rid of mouse-ideas completely, they keep turning up again and again, and nibble, nibble-no matter how often we drive them off. The best way to keep them down is to have a few good strong cat-ideas which will embrace them and ensure their not reappearing till they do so in another shape.
Ideas are the engines of progress. They improve people's lives by creating better ways to do things. They build and grow successful organizations and keep them healthy and prosperous. Without the ability to get new ideas, an organization stagnates and declines and will eventually be eliminated by competitors who do have fresh ideas.
If a mathematician wishes to disparage the work of one of his colleagues, say, A, the most effective method he finds for doing this is to ask where the results can be applied. The hard pressed man, with his back against the wall, finally unearths the researches of another mathematician B as the locus of the application of his own results. If next B is plagued with a similar question, he will refer to another mathematician C. After a few steps of this kind we find ourselves referred back to the researches of A, and in this way the chain closes.
The mathematician is entirely free, within the limits of his imagination, to construct what worlds he pleases. What he is to imagine is a matter for his own caprice; he is not thereby discovering the fundamental principles of the universe nor becoming acquainted with the ideas of God.
A mathematician, like a painter or poet, is a maker of patterns. If his patterns are more permanent than theirs, it is because they are made with ideas.

I think you can fan the flames, but I think in the same way that a mathematician is a mathematician - He's not taught to be a mathematician. He either has a feeling for equations and an understanding and delight in it, not only in the purity of it, but in its beauty as well.
Some of the elements of sleep hygiene are basically the same as good health practices. Nicotine, caffeine, and alcohol all negatively impact sleep, the more so the closer they're consumed to bedtime.
The constructs of the mathematical mind are at the same time free and necessary. The individual mathematician feels free to define his notions and set up his axioms as he pleases. But the question is will he get his fellow mathematician interested in the constructs of his imagination. We cannot help the feeling that certain mathematical structures which have evolved through the combined efforts of the mathematical community bear the stamp of a necessity not affected by the accidents of their historical birth.
