Occam's (Ockham's) Razor

In Wind, Sand, and Stars, Antoine de Saint-Exupéry wrote "Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away."

There it is again, Ockham's Razor!

Science cites the Razor as an important influence. What is this influence and how does it operate? Please give a scientific answer.

Or is science shaped by influences beyond itself?

Ouroboros

Consciousness, says science, is biological process,
which is biochemical process,
which is chemical process,
which is physical process,
which is quantum mechanical process,
which is a probability wave,
which is only real when it has been collapsed by the act of perception,
which can be considered to be an act of consciousness.

Haiku for the New Year:

beneath the new snow
next year's garden regathers
to shock with beauty
