You ignore that it's entirely possible to have an infinite, monotonically increasing sequence with a fixed upper bound. Yes, people could keep getting taller without ever exceeding some defined limit. However we would begin to encounte

I don't mean to diminish the accomplishments or skill of chess players, but in my opinion being a perfect information game makes chess, like go, much less interesting. It means that, in principle, it is simply a matter of running Minim

This article has a bunch of problems and is fairly typical of mass-media reporting in this area. Suborbital vehicles such as SpaceShipTwo, New Shepard, and Lynx are lumped together with orbital launch systems. I do not think the distinction

He did say total deceleration , so I believe he meant the landing burn starts at a velocity of 40 m/s and consequently the total ΔV of the landing burn is 40 m/s. That said, I have no idea where he got that number, whether 40 m&#

Attempting to precisely define and codify what characterises a 'religion' is neither useful nor a well-defined goal. I think it would be entirely reasonable to, under the law, accept that if someone claims something is their relig

To elaborate on this point, "if you score 90 and above" could be parsed in two different ways: 1. "if [you score 90] and [you score above 90]" 2. "if you score in [{90} 'and' {x: x > 90}]"

In particular, I think Aeroflot Flight 593 [0] is representative of this sort of problem. Autopilot control of the ailerons was accidentally disabled without clear feedback of the change in mode, this led to overcorrection by the autopilot

I don't see how you reach that conclusion. It's possible that posessing some knowledge may lead to overconfidence, but that too is a problem with a lack of knowledge - knowing the limits of your knowledge. Knowledge is always bene
