Easy, you are looking for configurations of certain types.

No number thrice is easy, you say "how many ways are there to get a number thrice" which is 4, so there are 60 ways you can't get a number three times.

For no number TWICE you are saying you have to have all three digits different, which is a cascading probability;  think of it as 4 choose 1 x 3 choose 1 x 2 choose 1.  So it should be 4 x 3 x 2 = 24 ways to get no repeating digits.  That is, you have 4 options you can choose for the first digit, three for the second, and two options for the final digit.

I leave it as an exercise for the reader to extend to different bases and numbers of digits.

[dragdeler]

Thank you that is the perfect answer, I get both my number and I'm able to extrapolate to other configs.



Also 24 makes me happy because it got 8 and because it got 3, could not fall better.

[TD1]

You've put those numbers the wrong way around.

I think that's the answer you seek.

So, for some DnD shenanigans (Don't comment on the possibility of this, that'd be up to DM discretion), were someone to make a 2.25m^2 portal at the deepest part of the Marianas Trench with the other end on top of, say, a person, how much force would that person be hit by? I've been trying to find out how to calculate this, but unfortunately that's not my strong suit it seems.

I may or may not be coming up with a "Fuck you, me, and everything within half a mile" plan just in case.

[delphonso]

Water pressure at marianas trench is 1000 bars, or 15,000 psi

A fire hose is about 300 psi...
Though a water jet cutter is 35,000psi+.

I'm going to say, probably similar to being hit by a car for everyone within twenty feet, and less like a nuclear explosion.

[bloop_bleep]

Well, it's about 11000m deep, so the pressure would be

11000m * 1000 kg/m^3 * 9.8 m/s^2

which is about 1.078 * 10^8 N/m^2. The total force at the other end would be this multiplied by 2.25 m^2, but since the horizontal cross-sectional area of a person is about

36.7 cm * 13.3 cm

which is approximately 4.88 * 10^(-2) m^2, the force would have about the smaller value of 5.26 * 10^6 N. This is about 537 metric tons of force.

Sounds like no matter what that guy under the thing is definitely dead and potently everyone else as well.

Well, the alternative is I do the same thing but do it somewhere like the surface of the sun. However, it depends on how the setting's sun works so that's less feasible.

And if it's day or night.

Someone's learned Gate, I see.


Just don't do the salt thing. We've learned not to do the salt thing.

[Great Order]

Maybe...

Just don't do the salt thing. We've learned not to do the salt thing.

That wasn't a gate spell, that was just a gate. And part of the reason I say "Don't give the players an inch or they'll take a country"

You laugh at reality and you sigh at the facts.

What does that make the facts?

not fun facts

Or inconvenient truths

[Rolan7]

Why is human head hair so much longer than that of other primates?

[heydude6]

Did some googling and was looking for an answer more interesting than "sexual selection", but I couldn't. The answer is simply sexual selection, like peacock feathers.

As a consolation prize though, apparently hair and fur are two distinct terms. Fur grows and sheds and replaces itself within a one-year cycle while hair should last for years. Hair was literally something humans invented just to get laid (and protect our heads from the sun)...
