I will sometimes see science blog posts refer to "The Second Law" as if we all knew exactly what they meant.
As far as I can tell, "The Second Law" could refer to any of:
- F = ma
- A line joining the planet to the Sun sweeps out equal areas in equal times
- A robot must obey any orders given to it by human beings, except where such orders would conflict with the First Law.
- The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
(And probably a number of other things.)
