John Gabriel (a non-mathematician) claims in his blog that the real numbers are countable. The author tries to enumerate the real numbers in the interval [0, 1) by writing out all those whose decimal representation has one digit after the dot (0.1, 0.2, ..., 0.9), followed by those with two digits after the dot, then those with three digits, and so on.
He goes on further to say that this establishes a procedure for writing
down an ordered sequence of numbers in which every real number of the
source interval will appear eventually (although, it should be clear
that any number with an infinite decimal representation will never
occur in his sequence of numbers).
This argument shows that the subset of real numbers between 0 and 1 that have a finite decimal representation is countable. Although, it fails to work for the interval [0, 1).
It's rather entertaining to watch fellow mathematicians humor him. Either way, things like this happen all the time :-D.

I find your entry rather amusing. Accusations against my credentials and confused arguments don't make you appear any more credible.
Is it not strange my knols have such high ratings? Hmmm, I wonder, could this be because the knols make sense or could it be because the mathematics academia are so dumb that anything making even a bit of sense seems to be more credible than what they teach?
seriously, do you search for people who link to you in order to insult them personally? this is at least the second place I've seen someone make fun of your ideas, and both times you went out of your way to answer.
