To Test or De-Bug. That is the Question.

The Wall Street Journal: “It is much more efficient—and far less painful—to test each small part before stringing many pieces together. That way, the failures are less frequent, more informative and a lot easier to fix.”

“Throughout most of human history, people’s interactions with the physical world … were based on various rules of thumb. Those were learned (and, often, unlearned) over generations and ‘debugged’ by chance observations. Science in the modern sense begins with the insight that it is better to test your understanding thoroughly in simple situations, where debugging is more manageable. This allows you to make cumulative progress. That may come in smaller steps, but it is more likely to endure.”

“While the grand philosophers of Galileo’s day constructed vague systems of the world, often inspired by sacred texts and Aristotle’s metaphysics, he minutely studied the way that balls roll down inclined planes. Galileo nailed it, and his was the more lasting contribution. As Sir Isaac Newton put it, ‘Tis much better to do a little with certainty, & leave the rest for others that come after you, than to explain all things by conjecture without making sure of any thing’.”
