Science Quotes by Hermann Weyl (5 quotes)
Before you generalize, formalize, and axiomatize there must be mathematical substance.
— Hermann Weyl
In geometric and physical applications, it always turns out that a quantity is characterized not only by its tensor order, but also by symmetry.
— Hermann Weyl
My work always tried to unite the true with the beautiful, but when I had to choose one or the other, I usually chose the beautiful.
— Hermann Weyl
Symmetry, as wide or as narrow as you may define its meaning, is one idea by which man through the ages has tried to comprehend and create order, beauty and perfection.
— Hermann Weyl
The Greeks made Space the subjectmatter of a science of supreme simplicity and certainty. Out of it grew, in the mind of classical antiquity, the idea of pure science. Geometry became one of the most powerful expressions of that sovereignty of the intellect that inspired the thought of those times. At a later epoch, when the intellectual despotism of the Church, which had been maintained through the Middle Ages, had crumbled, and a wave of scepticism threatened to sweep away all that had seemed most fixed, those who believed in Truth clung to Geometry as to a rock, and it was the highest ideal of every scientist to carry on his science 'more geometrico.'
— Hermann Weyl
