Looking a little deeper makes it even more amazing. Every letter in every word is actually a number. Every ebook contains nothing but numbers. Every upper case letter is actually a number between 65 and 90. Lower case letters are numbers between 97 and 122. A space is actually the number 32. Other formatting characters, visible and invisible are other numbers.
So all you readers are really math wizzes and you didn't even know it.
Yes this stuff is amazing. And wonderful. And fun. Even useful. I spent 35 years as a programmer, mostly low level, so, even though I'm now pretty out of date, I have a fair understanding of what's under the hood and the more I learn the more amazed I am and the more I realize how much more there is that I don't know.
