Failure as a Prerequisite to Success

If a man wants to succeed in his work, that is, to achieve the anticipated results, he must bring his ideas into correspondence with the laws of the objective external world; if they do not correspond, he will fail in his practice. After he fails, he draws his lessons, corrects his ideas to make them correspond to the laws of the external world, and can thus turn failure into success; this is what is meant by "failure is the mother of success" and "a fall into the pit, a gain in your wit".

 Watch a Scientist's Deeds, Not Words

If you want to find out anything from the theoretical physicists about the methods they use, I advise you to stick closely to one principle: don't listen to their words, fix your attention on their deeds. To him who is a discoverer in this field the products of his imagination appear so necessary and natural that he regards them, and would like to have them regarded by others, not as creations of thought but as given realities.

 Science Must be Private

The feeling of understanding is as private as the feeling of pain. The act of understanding is at the heart of all scientific activity; without it any ostensibly scientific activity is as sterile as that of a high school student substituting numbers into a formula. For this reason, science, when I push the analysis back as far as I can, must be private.

 Definition of Medicine

Medicine is the science by which we learn the various states of the human body in health and when not in health, and the means by which health is likely to be lost and, when lost, is likely to be restored back to health. In other words, it is the art whereby health is conserved and the art whereby it is restored after being lost. While some divide medicine into a theoretical and a practical [applied] science, others may assume that it is only theoretical because they see it as a pure science....

 Practicing Motor Skills

In fact, babies do improve their motor skills much as adults do—as a result of diligent practice. New skills, such as walking independently, don't suddenly emerge out of nowhere but gradually build out of prior, simpler abilities—kicking, standing, and walking with support—after weeks or months of trying. The only difference between infant and adult motor learning (aside from the fact that infants seem to crave the exercise more than most of us) is that babies can train themselves in a ...
