“Anyone who has had actual contact with the making of the inventions that built the radio art knows that these inventions have been the product of experiment and work based on physical reasoning, rather than on the mathematicians' calculations and formulae.”

— Edwin Howard Armstrong

As quoted in Electronics (2005) by P. Arun, p. 310
Context: Anyone who has had actual contact with the making of the inventions that built the radio art knows that these inventions have been the product of experiment and work based on physical reasoning, rather than on the mathematicians' calculations and formulae. Precisely the opposite impression is obtained from many of our present day text books and publications.

“The idea that an afterlife had been invented to reassure people who couldn’t face the finality of death was no more plausible than the idea that the finality of death had been invented to reassure people who couldn’t face the nightmare of endless experience.”

Edward St. Aubyn (1960) British writer

At Last, Chapter 3

“We believe that the elements in the chemical formula of our creative work, problem, invention, and art, correspond to the challenges of our age.”

El Lissitsky (1890–1941) Soviet artist, designer, photographer, teacher, typographer and architect

“The result of the mathematician's creative work is demonstrative reasoning, a proof; but the proof is discovered by plausible reasoning, by guessing. If the learning of mathematics reflects to any degree the invention of mathematics, it must have a place for guessing, for plausible inference.”

George Pólya (1887–1985) Hungarian mathematician

Induction and Analogy in Mathematics (1954)

“Anyone who compares the bibliography with the reprinted papers will notice that mathematics and physics have not been given equal treatment. There is a strong bias in favor of mathematics. The bias arises from the fact that mathematical papers, provided that are correct and not trivial, have permanent value, whereas most papers in physics journals are ephemeral. For this reason, it is customary to publish complete collected works of mathematicians but only selected works of physicists.”

Freeman Dyson (1923) theoretical physicist and mathematician

“We do not have any production secrets. We invest a lot of effort and money in new research projects. However, before our new invention is used in real life, we usually invent something better. For this reason, we do not have a single patent to protect our inventions.”

“Sloan [American colleague artist who started his art by making etchings, c. 1920] not having been abroad [in contrary to Hopper himself], has seen these things with a truer and fresher eye than most... The hard early training has given to Sloan a facility and a power of invention that the pure painter seldom achieves.”

Edward Hopper (1882–1967) prominent American realist painter and printmaker

“In another thirty years people will laugh at anyone who tries to invent a language without closures, just as they'll laugh now at anyone who tries to invent a language without recursion.”

“Pure mathematics is much more than an armoury of tools and techniques for the applied mathematician. On the other hand, the pure mathematician has ever been grateful to applied mathematics for stimulus and inspiration. From the vibrations of the violin string they have drawn enchanting harmonies of Fourier Series, and to study the triode valve they have invented a whole theory of non-linear oscillations.”

George Frederick James Temple (1901–1992) British mathematician
