I randomly had the issue that after booting up Linux, I didn't have any sound. Turns out it was related to my Windows dual-boot setup! When restarting from Windows, Windows doesn't shut down my realtek audio device, but only puts

Oberon-2 was the first programming language that we learned in school, back in 2002. We used Pow! as IDE ( http://www.fim.uni-linz.ac.at/pow/pow.htm ). Good times, implementing sorting algorithms, Turing machines, and va

Historically, I'd say 60, because relative to it's size, it has many divisors (12), and among them a lot of useful ones (2, 3, 4, 5, 10), which is why our time system and trigonometry are probably based on it (360 = 6*60; 360 has

There are different ways to define pi. In real analysis, you first define the exponential function: exp(x) = sum (x^k)/(k!), then cosine: cos(x) = Re(exp(i*x)), where i is the imaginary unit, and then show that cos(x) has exactly one r

Not a paper, but 2×3×5×7×11×13 + 1 = 59×509 is a short counter example to the widespread misconception that adding one to the product of the first n consecutive prime numbers always yields a prime number. The reason you get away with this i

Interesting fact about Hilbert spaces: The inner product of a Hilbert space induces a norm and thus every Hilbert space is a Banach space. But what about the converse? Say we only have a normed vector space, can we decide if there is an inn

Since salination is essentially driven by the CO2 in the air, does this imply the CO2 we add to the air increases the rate of salination (f' > 0, where f(t) is the salt content of the oceans)? If so, does this affect ocean currents?

TL;DR #1 is correct. #2: Quantity usually means just a number but isn't a maths term. A measures is a function that maps sets to numbers. A probability is a special kind of measure. For finite sets it is correct. More specifically, the

You are mixing up a few things. If the set contains infinitely many objects, you cannot talk about proportions anymore, because the probability of every point is zero. Also, the term "measure" has a well defined meaning in mathema

Can someone please explain the physics behind 1) A "faulty connection" and why it fails at a certain temp? Is it a partially broken circuit that doesn't work anymore if resistance is too high? 2) Why airblowing fixes it. Beca

Interesting fact: Nuclear fusion, even if we'll make it work, won't stop global warming, because the heat it creates heats up the earth enough to bring us outside the Paris agreement: https://twitter.com/rahmstorf&

"Manipulating hundreds of thousands of rows" is exactly where R, dplyr and data.table are great at. I do that on a daily basis.
