Re: The Second Law of Thermodynamics...

You CAN get a closed system to turn heat into work. For instance, it is entirely possible that, at a given time, all the air molecules in a piston happen to be going in the same direction. However, the larger the scale, the more this becomes improbable (what's 0.5*10 -number of air molecules ?). Als...

Wait, but if you follow the traveling twin in an inertial reference frame, it's the OTHER twin who can be considered moving and so the other twin will be younger...

So does one twin see the other as younger, while for the other twin it's the opposite?

Also, you might be able to dissolve the ricin but not the salt with a nonpolar-ish solvent, though that's just conjecture.

And then there's always "permanent" eddy currents in superconductors that levitate magnets

Definitely one of the cooler things. With no resistance, the induced current is exactly that necessary to prevent the magnet from moving.
