The pressure of the water is ##p = \rho g h##, so gravity enters through the ##g##. But the force of the water ##pA## (where ##A## is...

There was the guy who stole a tank.

That's right. I incorrectly thought the stated problem is whether there are two Bill Perkinses but it's actually whether any two...

I repaired an error in my calculations. I seldom get it right the first time.

Edited to correct mistake. What you want is the Poisson distribution. Assume that the likelihood that BP lives in a given house is...

I think you mean 83 ps. The speed of light is about 30 cm/ns, so 2.5 cm must be less than a ns.

In a competitive environment 'Natural Intelligence' does the very same. Only imposed constrains (awareness and tolerance of society)...

Either laziness or to increase output. An enterprising individual released at least 364 AI "history" videos in a month. They were...

Researchers found that AI agents — software trained to perform tasks independently — engaged in a “broad pattern” of misconduct after...

I'd think a civil suit against OpenAI much more likely than a criminal one.

Yes, but to measure the Hubble constant, you need to know the distances.

All you can do is compare the rotational or orbital planes of two heavenly bodies and conclude that their rotational direction is either...

But then all heavenly bodies rotate counterclockwise. Is that useful?

Yet, the right-hand rule provides an unambiguous direction towards the rotational north pole. This isn't as much of a problem as you...
