Momentum doesn't really work this way. The only things that change the difficulty of deflecting something are it's mass, and the remaining time to impact. Having a lot of momentum doesn't change how much force is required to give something

They just indicate some arbitrary number of factorials, with no particular restrictions.

There's a separate emergency brake system to prevent the elevator from falling, because you also need to be safe if the cables holding the elevator up break (this is actually the technology that lead to the first elevators). The counterwe

Marketing reports and novels have specifications just as real as any physical engineering project, you're just required to guess at what exactly they are. Whatever you're making, there's going to be some set of things that it must accomplis

Complete tangent, but: You can share files with Dropbox without the reciever having a n account, and as far as I can tell without installing software on either computer. Just login to dropbox.com, upload, and move the file to a public fold

The point isn't whether there's an excuse or not. It's just that in practice it is better tactics to try for just open journals first. This isn't a moral argument, it's a pragmatic one.

I apparently entered my test cases wrong in lots of interesting ways. I think I've actually found essentially the same solution you have, it turns out I had the exceptions and the actual solution backwards: n avargl qrterr ebgngvba naq n e

One way is to view this as a geometry problem, 2d for convenience: a column represents a point in the plane, and matrices are transformations that can be applied to that point. Then the problem becomes, find a pair of transformations such

95-99% of the time, I'd actually prefer the built in android calculator, because the buttons are bigger and I'm only doing simple arithmetic. I'm perfectly willing to sacrifice the remaining times in exchange for not having to carry anothe

This would eventually get to be true, but it would probably take a stupidly long time: it won't happen until people have actually seen the long term results of things multiple times. Also, short-term thinking is fairly hardwired into human

It turns out that most of the security of credit cards takes place after the actual transaction. It's largely done by using software to look for transactions that look somehow wrong, or by reversing charges when you look at your bill at th

These are not necessarily contradictory. Fukushima can quite easily be lacking all of those things because they're stuck on the wrong side of Japan, where more people who don't know how to fix roads or speak Japanese won't help. Similarly

A password of that sort is both not that hard to remember and probably fine on a post-it not on the monitor of your home computer. There's really not much overlap between the sorts of people who will break passwords and who will be in a po

generalization/key point as I see it: doing x for x's sake or as an excuse to be self-righteous is bad, do things because they make you happy or make something easier. This is actually a really useful rule in a lot of other places too.
