Philosophers and Crackpots

Physicists believe that we and only we can figure out the universe.
That, and our arrogance about it, is why we are the main target of many philosophers and crackpots (note that there is a distinction).
Yes, modern physics has some deep philosophical implications. The sad part is that they seem to escape the philosophers, as most tend to have a very narrow and inaccurate picture of what it represents. If I ever hear another person claiming that relativity and quantum mechanics say that everything is relative and that we are uncertain about everything and use this to start some deep philosofical discussion, I think I'm going to cry.
But also we have the crackpots. What is a crackpot? Well, this articles summarizes very well the set of rules to detect them. A perfect example of one is this one. Note how it starts with a vague idea of what quantum mechanics, electromagnetism and relativity are. Then, writes one equation, and points out that since part of the equation is less than one, it therefore must be a probability. And then claims that with good expensive equipment it could be tested out. Tested out what? No predictions are given, no logical argument, nothing. Go back to the set of rules to detect crackpots, and you will see the article follows most of them.
Why are there so man crackpots, and in particular, why are there so many with a technical background? This very interesting post proposes an explanation.
