That article is false. From all those authors, it appears none of them have had higher mathematics. I won't say throw that book away because they just might have some correct and valuable things in there. But, that particular article is wrong.
I have had 36 credit hours of graduate mathematics. So, I will pit my knowledge of infinity against theirs.
Also, I am sure the internet can verify what I am saying. I will research it next time I get on. Deal?
