He was a very promising theoretical physicist who was well respected for his fundamental physics knowledge (including useful public service like his contributions to the physics stackexchange and a very informative science blog). Then he became very zealous in his non-scientific beliefs (the current link being a good example). If anything, it is good to know about him as a cautionary tale.
