Quote of the Day

If you enjoy programming, philosophy, math, or any number of geeky topics, you're in the right place. Every day, I'll post a random quote from my extensive collection of Kindle highlights. Quotes do not necessarily reflect my views or opinions. In fact, part of my epistemic process is to consume a wide variety of contradictory material.


People with a fixed mindset fear failure as they believe it makes their innate limitations visible to others, whereas those with a growth mindset are less risk averse by seeing failure as an opportunity to learn and develop new skills.

For the physicist or engineer, two systems that obey the same equations have a kind of identity-or at least an analogy. And that, after all, is all our word analog means. A digital watch is nothing like the sun; an analog watch is the memory of a shadow’s circuit around a dial.

In 1965 in a paper beautifully titled “Path, Trees and Flowers,” Edmonds developed a bit more complicated method for finding the augmenting paths in general friendship diagrams. … Edmonds goes into a long digression on the nature of an efficient algorithm. While he realizes that no formal definition can completely capture the intuitive idea of efficiency, he suggests a notion of efficiency by having a procedure that uses computation time that is “algebraic” in the size of the problem, for example, 100^4 or 100^2 or 100^12. Later this class of problems would become known as P (for “polynomial,” which replaced Edmond’s “algebraic”) and come to represent problems we can solve efficiently. That’s the P side of the P versus NP question.
