Time Conversions
In physics and other
sciences, time is considered one of the few fundamental quantities.[2] Time is used to define other quantities –
such as velocity – and defining time in terms of such quantities would result in circularity of definition.[3] An
operational definition of time, wherein one says that observing a certain number of repetitions of one or another
standard cyclical event (such as the passage of a free-swinging pendulum) constitutes one standard unit such as
the second, is highly useful in the conduct of both advanced experiments and everyday affairs of life. The
operational definition leaves aside the question whether there is something called time, apart from the counting
activity just mentioned, that flows and that can be measured. Investigations of a single continuum called
space-time brings the nature of time into association with related questions into the nature of space, questions
that have their roots in the works of early students of natural philosophy. -

About RF Cafe RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived... |
