Over time the word change is common to exist because of what it means to adapt to them. The way we relate to each other in conversation and the way we dress has changed. Now we see references that are part of transitions such as those used to measure distances, sizes or weights. New measurement scales have been confirmed for tiny or gigantic magnitudes.
The General Conference on Weights and Measures (CGPM) adopted two new prefixes, Ronna (R) and Quetta (Q), to express tiny or gigantic orders of magnitude, increasingly common in modern science.
What before or now seems normal to measure by centimeters, meters, grams and kilograms, now new indications are presented to better understand very small or large dimensions. A reality that leads us to think about including our lives at distances or sizes or very large or small.
Although everyone knows the kilo, which expresses, for example, a number of meters or grams in a thousand –with three zeros after the unit–, only scientists use the terms Zetta (Z) and Yotta (Y), which express, respectively, a quantity with 21 and 24 trailing zeros.
These ways of measuring already have a name and have been accepted and created in The General Conference on Weights and Measures There are fanciful names such as “Brontobytes” or “hellabytes”, which describe the hard drive space where audiovisual records, images or whatever you want to store are stored.
Even so, it does not seem like enough time for some generations that years ago worked with 64kb of ram and hard drives of barely 5 Mbyte, bytes that later gave space to prefixes such as kilo, mega and now new indications to better understand how much space we have on our hard drive to be able to use it according to the desired work.
New ways to measure
Spaces that are necessary in computers or private phones due to the accumulation of photos, videos, audios, and texts that no longer necessarily occupy real disks but end up in the cloud or virtual disks, which is a way of doing business for some companies like Google that offer up to terabyte or thousand gigabyte disks.
The indicated prefixes will not refer only to the infinitely large. They will also apply to the infinitely small, for example, in “quantum science” – particle physics – where very, very small things are measured.
The new Ronna (R) and Quetta (Q) prefixes express quantities with 27 and 30 zeros after the unit, respectively.
Thus marking a milestone or reference in knowing how to measure what is either very large or small.
For example “the Earth weighs about 6 ronna grams”, that is to say a 6 followed by 27 zeros.
These changes were adopted on Friday at the Palace of Versailles (west of Paris, France) by scientists meeting at the CGPM, which is held every four years.
time that may be enough to see again new references of sizes, distances or weights. The world has been changing rapidly and the units of measurement too.-
