Re: 0969: "Delta-P"

I remember working this out elsewhere: http://www.scp-wiki.net/forum/t-101083/scp-249 I don't actually know any fancy flow equations, and I just assumed there was no friction, and all the energy went into velocity. I got 390 m/s, 18 kg of TNT equivalence per cubic meter, and 14 tonnes of TNT per sec...

Re: 0910: "Permanence"

This reminds me of when I named my computer. I really should have consulted someone who knew Latin. I named it Machina Ex Deus, which, from what I understand, is just Deus Ex Machina with different emphasis. Anyone know how to say "the Machine from God"? I probably should have just called ...

Re: 0871: "Charity"

If you really cared, you'd dedicate your life to earning as much money as you can, and do as much as you can to find the right charity. Also, you'd stop reading webcomics and get a job or internship, rather than just not spending money on yourself. (That's the part where I fail.) I've thought about ...

Re: 0816: Applied Math

I notice she would have gotten nearly twice as much money by pointing out that she proved all of the Millennium Prize Problems . In any case, I'm sure they'd consider that more important than any of them, and the should at least give her one million-dollar prize. Shouldn't she use a proof checker? I...

Re: "Children's Fantasy" Discussion

It's funny and all, but memory doesn't work that way. You only have to lie about it until you convince yourself it didn't happen. On a side note, couldn't you just test the ring for isotopes? That world probably doesn't have the same proportions as ours does, and even if it does, they didn't test a ...

Re: Outsmarting the Genie

I got too bored to read the thread fully, so I'm sorry if I repeat anything. The original poster wondered why the genie would grant peoples wishes. In the original story, it was because he was magically forced to by an even more powerful human sorcerer. This would explain why he'd want to kill all o...

Re: Probability puzzle... genetics based

Both the Zot problems are impossible. They require knowing how common each allele is. The person who answered the first Zot problem assumed each allele was equally likely. If this was true, there'd be three times as many Zots of one color than the other, which wouldn't go unnoticed. If both colors a...

I figured out the main answer when I last saw this thread (and the rest since), but didn't bother posting it. It looks like you still haven't answered it (I'm not sure, I didn't bother to read more than the last page), so here's the main part: You just have to avoid the middle sister. She's the ...

Re: don't click here or you'll lose!

I've read three variations on the game. One you lose by remembering the game, one by remembering that you're playing, and one by realizing that you lost. For the first two, you can't lose if and only if you can't remember, so permanently forgetting i.e. amnesia is provably the only way for someone w...

Re: Desert Island-What to bring?

I have I few ideas: It only rains once a week, and there's no water. You'd at least either something to store a week's worth of water in, or some kind of purifier. I'd also want a reason to live. Given that I just used a glider that can go 1,000 miles, this must be a futuristic setting. I'd bring so...

Re: Help me stop a alien invasion.

Hide.

Hide all of civilization!

Build every house with a basement bigger than it is. When the aliens are about to come, lower the houses into their basements, close off the tops, and have machines throw sand into the air. When the sand settles, the city will look like a desert.

Re: How do you stop this alien.

Put some people on a rocket that can accelerate continuously. They will have an event horizon behind them, where light from anything past that horizon will never catch up to them. If they accelerate fast enough or start out far enough, the robot will be on the far side of the horizon. See http://en....

Re: What else can we imagine?

The question isn't what numbers you can make, but when you stop considering them numbers. I put the line somewhere between matrices and functions.
