When someone offers an interesting snippet of news, do you have a compulsive need to lecture us all? It's really tedious of you.
Oh boy, get ready for another pejorative laden comeback. Let's see. It could be along the lines of, the Jingoistic Kewpie now shows her true color defending such a reprehensible person.
...sadly enough you use a lot of disparaging words on people and tend to use absolutes and superlatives were they are uncalled for.
You could amke much more points if you would try not to win by insulting, which will not give you a win.
You were correct in substance about the definition of amateur and professional.
sonhouse was quite correct in pointing out that a PhD in natural science indicates that the person is in the highest decile in math education most proabaly. So for the average person: He is not strictly an "amateur" (though he is in the stricvt sense of the word as defined by the dictionnary).
He is not really an amateur, he has a Phd from Cambridge in medicine and is very interested in math problems.
The interesting math problem is in the field of two dimensional graph theory. de Grey excluded one of three possible solutions, probably renewing the zeal to find a solution.
So now you quibble over semantics. He in fact had a Phd, even if it wasn't in my 'medicine' statement. The amount of actual work would be about the same and he would have had to have had a significant degree of math education getting to the Phd.
What you do is jump on any kind of error as if that destroys the entire argument and then adding the invective's to top off your cake of cultural destruction.
But I am too stupid to have ever even thought out this post so therefore since I am a reprehensible pathological lying jingoistic American racist MALE, I must have hired a REAL person to have typed all this out, my personal intellectual engine I bought on Amazon to install on my multiCPU supercomputer in my basement that was actually invented by this genius I hired.
