Occam's Razor

There is a principle underlying all the Laws of Physics. It is a general principle influencing the nature and form of all physical laws. The principle is Occam's Razor, and it says, in it's various forms:

Physical Laws are simple.

The simplest answers are probably the best ones.

When competing hypotheses are equal in other respects, select the hypothesis that introduces the fewest assumptions and postulates the fewest entities while still sufficiently answering the question.

Occam's Razor is not a physical law or a hard and fast principle. In spite of it, the laws of science seem complicated to many people, incomprehensible to others. It is rather a rule of thumb, which scientists should be conscious of when deriving physical laws. If the law seems complicated or contrived, it may well be wrong. There may be an error in the derivation or the underlying assumptions may be wrong.

Many scientists think that physical laws should be aesthetically beautiful, part of a unified physical systems that floats like a golden glowing globe. Maybe the best example of this is the evolution of the principle of relativity – which states that the laws of physics should take the same form is any system in uniform relative motion to any other. Galileo first formulated a principle of relativity, and said that things speeded up and slowed down because they were acted upon by forces..The system of Newtonian mechanics, and Newtons' three laws of motion, which preceded Einstein's relativity, is certainly aesthetic, and seemed for hundreds of years to explain everything. It made possible much of modern engineering and the industrial revolution because of the way it treated forces as terms in equations which could be calculated and predicted. Einstein took the view that any physical system should be actually artistic, and many artists were influenced by his principles of relativity and his idea of a unification of a curved integrated spacetime, and the idea of time being just another dimension of space.
