There's no denying that Newton was a real prick. But he could still get his ideas accepted by people (some slower than others, of course). That's different from the cranks who can't find *any* professional acceptance for their ideas and then go on rants about how they're being "kept down by the Man", so to speak.
You mean like his ideas on alchemy? (You do recall what they found inside his body when they exhumed him, don't you?)
Ichneumon: "That's different from the cranks..."
If I got excited every time I ran into a "cranky" PhD, I'd have had to change professions decades ago. I both expect and ignore their "eccentricities" and that is how I view João. Maybe he has something to offer, maybe he doesn't, or maybe all he can do is to stimulate my thoughts down avenues he never intended. But I'll read him before I make that judgment.
