True, one should not waste energy about Motl. But he is so smart, rude and unreasonable that I cannot resist making fun of him. One of my male friends – yes, they do exist – has the right description for what guys like him are doing in physics research: mental masturbation.
It must be said that we speak about Motl's past: he is not a physicist any more. At present he converted to being a frustrated anti-global-warming activist. In his research past, the conjectures he explored – supersymmetry and strings – were only for his own enjoyment. Nobody else cares about these conjectures, because they do not agree with experiment. But a few rare people do share the same hobby.
The best is that Motl recently told in his blog why he doesn't want to explain his past research to the general public: "it is like throwing pearls to swines." I had never seen this expression, which is from the bible, applied to this specific hobby.
Motl is much better than Sarah Palin. Thus there is only one conclusion: Motl for president!
