Occam's Razor

August 2, 2010

Occam’s Razor is a heuristic (rule of thumb)  used in many areas of science and philosophy. Credited to Franciscan friar William of Ockham; “entities must not be multiplied beyond necessity” is often reworded as “the simplest explanation is usually the right one”.

I like the way the medical community explains Occam’s Razor; “when you hear hoofbeats, think horses, not zebras.”

Occam’s Razor is not a scientific law, theory or rule. It is more of a reminder not to over complicate a problem. Not to consider more possible causes than necessary.

♦ This is a very simplified view of the overall implications of Occam’s Razor in the scientific world but it is a full and complete explanation of the heuristic itself.

arise is an irregular base verb (present tense)

arose is past tense

arisen is past participle (use with “has”, “had” or “have”)

You never know when another opportunity will arise.

Out on the lawn arose such a cladder.

She has arisen from her slumber.

Prescience, Precedence

prescience- foresight

precedence- priority

You have to study all of your vocabulary list unless you have the prescience to know which words will be on the test.

Doing your homework takes precedence over going out to play.
