Measuring and Calibration

Hestia dev: /* Time: the second */ added the "Human" way to track time From the "Time" page. i didnt know there was already a page for measurement

The '''International System of Units (SI)''' is the modern metric system used globally for precise measurement. It defines seven base units (meter, kilogram, second, ampere, kelvin, mole, and candela) from which all other units are derived. These units are '''universal, coherent, and based on fundamental physical constants'''. By adopting SI units, a post-collapse society can '''restore scientific progress, fair trade, and efficient resource management''', laying the groundwork for sustainable development.
= Useful Things to Note =
== Scientific Notation ==
Numbers can get large really fast. To shorten this so that we don't have 30 zeros floating at the end of every number, we use some basic math to describe a notation. If the number has a E(some number here), e(number), or even x10^(number), this stands in the place of x10(number).

This means that you can shorten the number 467,110,000,000 to 4.67110000000x10^11 or, roughly 4.67E11. A negative number means the same that any negative exponent means. (''See basic rules of [[Math]]'')

This means you can turn the number 0.000000846 to 8.46E-7.

== Prefixes ==
Because the previous notation can be hard to read, prefixes are available to whatever unit you want. For instance, instead of 2.53x10^-5 meters, you could say 25.3 µm which means 25.3 1 thousandths of a meter. This is much easier to picture even though it is still really small.

A common set of these prefixes go as follows:

= The Units =
== Distance: the meter ==
The '''meter''' is described to be roughly the length of a walking step, using the more precise definition of '''the distance light can travel in 1/(299,792,458) seconds.''' This comes out to be roughly 3.33564095E-9 seconds

To approximate the meter, several methods exist:

# a second-pendulum: by suspending a mass from a length of one meter

== Mass: the kilogram ==

== Time: the second ==
The '''second''' is historically defined through the '''duration of the day'''. One day is divided into 24 hours, which are first divided into 60 minutes which are in turn divided into 60 second each.

* 1 day = 24 hours, 1 hour = 60 minutes, 1 minute = 60 seconds.

More recently the second has been redefined as a number of vibrations of the cesium element, but in everyday life this definition does not have practical use.

Theres also a "human" way to track time, But it can differ on all sorts of elements. Take this as a "basic" way to tell time.

Hestia dev: added the "Human" way to track time, I hope that this makes a good start to explain time

Time, in human words is, Relative. There are two easy ways to track it. The human way. And the sun way.
