time

one fine afernoon, i asked my friend, "what is time ? define time"...
she wondered, "why?"
i said, "just do it"
she was left thinking for a while... and then came, "one moment to another, is time."

simple ... wasn't it ?
one moment to another. a mensurable metric. a scale was taken for granted, two points were marked on it, and the distance between was marked as the timespan. end of story.

but, is it that simple ? think again. so many things depend on time. its a basic unit, with mass, length and temperature. there are only four basic entities... everything else, is derived. speed, force, pressure, energy... everything!!!

okay, set apart schoolbook science. lets take a peek into the real world.why do we have to measure time ? why does everyone have to follow the same scale ? have u ever wondered that there are different units for length, mass and temperature, but the entire world follows the same unit for time.theres foot and meter for length. theres pound and gram for mass. theres centigrade and fahrenheit for temperature... but, theres only SECOND for time, everywhere!!! why all of us have agreed to bind ourselves to a timeframe ? why at all do we need to measure time ? we cannot hold time. we cannot alter it, stretch it or shrink it, cut it, touch it, add it, subtract it, compare it.... then why do we need to measure it ? we cannot undo or redo.... create or erase time.

i am pretty confused. i myself do not know how to put what i am thinking of. i cant quantify my perception of time. its not something that you can see, or show. we invented the clock to crystallise the measurement of time. but, clock again, doesnt measure time directly. its just a device with a constant rotational velocity, and the angular distance travelled by it gives an indication of time. for quartz watches, it depends on crystals with fixed oscillation frequency and the number of oscillations done under a particular voltage gives an indication of time.
we CAN NOT measure time directly.
in fact, we cant even measure length and time directly. length is measured by comparing the object in concern to a predefined object like the ruler, or the measuring tape. mass is measured by comparing it with some standard object like the iron weights. in free space, we can measure nothing.


what exactly am i talking about ??
