New units are added for the first time in 31 years. The unit of science (the world) that humans grasp is expanding.

【Four new units are created that greatly exceed the peta! The earth weighs “6 lonagrams”.】

・New units were added to the International System of Units (SI) prefix on November 18, 2022

・Giga and Tera are well-known, but even larger are Ronna and Quetta. And now we’ve added Ronto and Quecto, which are even smaller than Nano and Pico.

・The last time the unit was added was in 1991, so it has been about 30 years since the last addition.

・Ronna is followed by 27 zeros; Quetto is followed by 30 zeros. The symbols are capitalized “R” and “Q” respectively.

Ronto is a decimal point and 27 zeros. The quecto quecto has a decimal point and 30 zeros. The symbols are “R” and “Q” in lower case, respectively.

・Naming prefixes ending in “a” for larger numbers and “o” for smaller numbers

・The names Ronna (R), Quetta (Q), Ronto (r), and Quecto (q) were chosen because R and Q were the only letters of the alphabet not used in other units or symbols

 

These are the quotes from the article

 

 



 

Unit of science = Unit understood and grasped by human science (world)

 

This is the first new unit added in about 30 years.

 

Table borrowed from wikipedia.

 

You may have often heard of tera, peta, nano, or even pico. But there are so many more units than that.

 

The new unit is 30 zeros and 30 decimal zeros, which is an unimaginable number.

 

This time, I think about the additional units,

that the breadth of what science can grasp has been further broadened.

 

For example, I don’t think scientists hundreds or thousands of years ago could have even recognized the above mentioned units (world). (And even if they had recognized them, I don’t think they would have been at a level where they could handle them.)

 

In other words,

 

Newly added units = units that current science is able to grasp, understand, and handle

 

I think it can be put this way.

 

The daily progress of science is truly amazing.

But what I think is, there is a good chance that in the next 30 years, another new unit will be added, right?

When I think about it, I sometimes wonder if there might be a unit = world that humans (science) have not yet grasped.

 

Words like “scientific considerations” and “scientifically” are often used,

But that is only “scientific in the current state of science.

 

What I’m trying to say is,

 

We must trust in the science that humans have accumulated, and yet, somewhere along the way, we must remain humble.

 

I was thinking about this from the discussion of adding new units.

 

See you then.

 

Naming prefixes ending in “a” for larger numbers and “o” for smaller numbers. Why is that? I looked it up and couldn’t figure it out. Instead, during my research, I learned that since the 17th and 18th centuries, Latin and Greek (Latinized Greek) have been used for scientific names.
