Work
Pedro Nunes lived in a transition period, during which science was changing from valuing theoretical knowledge (which defined the main role of a scientist/mathematician as commenting on previous authors), to providing experimental data, both as a source of information and as a method of confirming theories. Nunes was, above all, one of the last great commentators, as is shown by his first published work “Tratado da Esfera”, enriched with comments and additions that denote a profound knowledge of the difficult cosmography of the period. He also acknowledged the value of experimentation.
In his Tratado da sphera he argued for a common and universal diffusion of knowledge. Accordingly he not only published works in Latin, at that time science's lingua franca, aiming for an audience of European scholars, but also in Portuguese, and Spanish (Livro de Algebra).

Famous quotes containing the word work:
“There was a deserted log camp here, apparently used the previous winter, with its “hovel” or barn for cattle.... It was a simple and strong fort erected against the cold, and suggested what valiant trencher work had been done there.”
—Henry David Thoreau (1817–1862)
“One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man.”
—Elbert Hubbard (1856–1915)
“... you can have a couple of seconds to rest in. I mean seconds. You have about two seconds to wait while the blanker is on the felt drawing the moisture out. You can stand and relax those two seconds—three seconds at most. You wish you didn’t have to work in a factory. When it’s all you know what to do, that’s what you do.”
—Grace Clements, U.S. factory worker. As quoted in Working, book 5, by Studs Terkel (1973)
