Steve Dutch is a professor of Natural and Applied Sciences at the University of Wisconsin-Green Bay.
He has a quite a few interesting pages on his web site.
Let us start off with the page where I got the title to this entry: Science, Pseudoscience, and Irrationalism.
Then let us read about Self-Appointed Experts (quite a nice rant I think, and he makes some very good points.)
Then I’ll close with Dutch’s Laws of Just About Everything.
There is plenty more to read there, so go check it out!
