Q
quadratic time algorithm
“better with more computational speed, but not quite as rapidly. So for example, if you had what's called a quadratic time algorithm, that would be like grade school multiplication. Like if you…” (Tim Roughgarden)

Quadrature of the Parabola
“Okay, so let's think about another case. In Archimedes' wonderful treatise, the Quadrature of the Parabola, he set himself the task. He had a parabola and a segment,” (Joel David Hamkins)

qualitas
“and then Cicero imitating this in Latin makes up the word qualitas, quality, right? So we use this word all the time, quality, qualitative. It literally just means houness, what's-it-like-ness,…” (Richard Polt)

quantifies
“Measuring quantifies what is otherwise vague. It makes it exact, it makes it precise, it makes it replicable, it makes it universal. It is this, the number is the same for everyone.” (Lee Braver)

quantum computers
“Okay, you say, but I also keep hearing about these quantum computers. So what's up with that? Like, did Turing already have in mind quantum computers? Well, I don't know the answer to that question…” (Tim Roughgarden)

Quantum Entanglement
“If you measure A on particle one and A on particle two, the results will always be opposite. If particle one turns out to have A value plus one, particle two will have A value minus one. The same for…” (David Albert)

quantum mechanics
“But we don't have them. We don't believe those anymore. We've had scientific revolutions since then. Einstein and quantum mechanics have shown... Einstein showed that time and space are not Newtonian…” (Lee Braver)
