A brief description of the laws in the cage this week, taken from wikipedia.
Boyle's Law: For a fixed amount of gas kept at a fixed temperature, P
and V are inversely proportional.
Kepler's Laws of Planetary Motion:
1. The orbit of every planet is an ellipse with the sun at one of
the foci. An ellipse is characterized by its two focal points; see
illustration. Thus, Kepler rejected the ancient Aristotelean and
Ptolemaic and Copernican belief in circular motion.
2. A line joining a planet and the sun sweeps out equal areas
during equal intervals of time as the planet travels along its orbit.
This means that the planet travels faster while close to the sun and
slows down when it is farther from the sun. With his law, Kepler
destroyed the Aristotelean astronomical theory that planets have
uniform velocity.
3. The squares of the orbital periods of planets are directly
proportional to the cubes of the semi-major axes (the "half-length" of
the ellipse) of their orbits. This means not only that larger orbits
have longer periods, but also that the speed of a planet in a larger
orbit is lower than in a smaller orbit. His third law is based on the
foundation left by Copernicus, because he uses a mathematical
expression to show the correlation between T (time for one revolution)
and D (distance from the sun).

I had to go with Kepler on this one. Just look at the facts. Law one took out "Aristotelean and Ptolemaic and Copernican belief" in one shot. Law two further kicked Aristotle while he was down. Law three... less impressive, but probably just never got tagged to enter the ring.
All that against Boyle's rehash of the ideal gas law. Good luck with that.
I once made a song about Boyle's law. It went to the tune of "Girls" by the Beastie Boys. That's where my vote goes.
So whats the plan? Sing Kepler to sleep and then pummel him senseless? Should have picked a more mellow tune.
Kepler FTW.
While Boyle may be moire useful in everyday life Kepler is just so much cooler. Kind of like a computer geek and a football star. And we all know how that turns out in a fight, don't we?
