Answer 1:

Turn off the lights when you leave the lab; our grant has been slashed.

Answer 2:

This is a hard question to answer because there are different types of physics, which follow different sets of rules. For large objects which we can see, Newtonian Physics, which were described by Sir Issac Newton, predict with perfection their movements and properties. For small particles, however, they no longer work.

For tiny particles, we use different laws, since they in no way act by the equations Newton created. Quantum Mechanics and Quantum Chromodynamics are used to explain the phenomena of small particles, but even these, along with the entire Standard Model of particle physics will have to be thrown out the window eventually.

To put it simply, if you are only concerned with the world you can see, Newtonian Physics is law. You can Google Newton's Laws if you want to see what they are. If you want to study the tiny parts of the universe, such as protons, photons and electrons, then there are no "basic laws". There are only postulates and principals and speculations.

I argue, however, that there are truths that I feel we have encountered through our journeys through particle physics. I truly believe that the speed of light is the speed limit of the universe, and that no information will ever travel faster than this. I also believe that the Heisenberg Principal of Uncertainty is immutable, and intrinsic to our universe. These two things might come into play someday when we actually do set down and derive a true set of laws by which all universal phenomena obey.
