Harristotelian Logic

The error with algebraic integers is so easily demonstrated, and so easily explained that it's hard to believe that people with decades of experience in mathematics wouldn't know it does exist and understand exactly how it functions.

And if so they've known for years.

I think you can wonder a lot and puzzle over a lot of things trying to comprehend how they've been operating with the error, and I've come up with various theories.

But make no mistake, if they DO KNOW then these are highly placed and often powerful people, even at top universities like Harvard and Yale who are fully aware they are teaching their students false information.

Fully aware? God help them. How can they? How could human beings do that to other human beings?
