Yeah, that's pretty impressive.
What a billion (not dollars, just a number) is, it turns out, we can feel in our direct experience, and it is wonderful: it is the number of heartbeats in a little over 30 years (consider that the heart beats at a rate of 60 beats per minute).
But a trillion - I don't know how to imagine it yet - in a way that would fit into my life experience.
- Approximately 10^12 bacteria live on the surface of the human body
- The total amount of money spent on defence and weapons in 2004 exceeded $1 trillion for the first time in human history.
- a trillion text messages were sent by subscribers on all networks worldwide in 2005
- Google has indexed over 1 trillion web pages
- the world's population is 6.5 billion. So one trillion people is about 153 planet Earths in terms of population.
According to the Internet.
direct experience, and this is remarkable: it is the number of heartbeats in a little over 30 years (think of a heart beating at 60 beats per minute).
Just recently before going to bed I was thinking about this subject while listening to my beloved's heartbeat. I was wondering how many times it can beat in a lifetime....

That's understandable, Ilya. Man perceives only what he is capable of experiencing by direct experience. There are about 10^28 molecules of air (i.e. oxygen, nitrogen and carbon dioxide) swirling around us, within a radius of about meters. So what? It's such a gigantic figure for us that we can't feel it.
I remember reading Perelman's books on amusing mathematics when I was a kid. There were examples that showed how big a million was. I recently managed to understand how small a billion (heart) is. But a trillion... yeah...
Thirty years ago, micro was a gimmick, but now nano bread is being distributed.
(and pico kneading... :)))
1 триллион долларов умещается в значении формата double (8 байт).
???
Это понятно, Илья. Человек воспринимает только то, что он способен ощутить прямым опытом. Вокруг нас, в радиусе порядка метров, крутятся примерно 10^28 молекул воздуха (ну то есть кислорода, азота и углекислого газа). Ну и что? Для нас это настолько гигантская цифра, что мы не способны ее ощутить.
Помнится, в детстве зачитывался книжками Перельмана о занимательной математике. Там были примеры, показывающие, насколько велик миллион. Мне недавно удалось понять, насколько невелик миллиард (сердце). А вот триллион... да уж...
I used to read this kind of literature myself. Even more recently, some ten years ago, there was a series of ROSMAN books, actually science for children, but phrases like "Did you know that..." never left me indifferent))
Let's start with the $100 note:
If you start with a $1 note, you get a skyscraper:)

I mean, paper money will pass into the next world (just type in a number and that's it).
I mean paper money will perish soon (typing a number on a keyboard and that's it). It's coming because electronic money is much easier to take from the general public (with a keyboard and maybe a mouse)... ?
