It's the Law: Answers

Gravity: not just a good idea. It's the law!

It's amazing how many 'laws' there are. It's one of the perks of being a scientist – along with getting bugs, diseases, and planetoids named after you.

Here are the answers.

  1. Newton's Law
  2. Einstein's Law
  3. Archimedes' Principle
  4. Bell's Theorem
  5. Buys Ballot's Law
  6. Grimm's Law

  8. Murphy's Law
  9. Godwin's Law
  10. The Hitchhiker's Guide to the Galaxy.
  1. Every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
  2. Energy equals mass times the velocity of light squared.
  3. The upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and it acts in the upward direction at the centre of mass of the displaced fluid.
  4. No physical theory of local hidden variables can ever reproduce all of the predictions of quantum mechanics.
  5. In the Northern Hemisphere, if a person stands with his back to the wind, the atmospheric pressure is low to the left, high to the right.
  6. A word beginning a voiceless stop such as /p/ in most Indo-European languages has for its cognate sound an aspirant /f/ in Germanic languages.
  7. There cannot be separate objects or entities that have all their properties in common.
  8. Anything that can go wrong, will go wrong.
  9. As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches 1.
  10. Nothing travels faster than the speed of light with the possible exception of bad news, which obeys its own special laws.

A parachute - surely the best way to fall out of a plane (especially with a brightly-coloured flare attached to you).
