This notion of course goes against the mainstream interpretation of the hacker persona (the geeky, socially recluse male that is more familiar with computers than he is with his own body). But if you peruse the articles here at Hacker News, it encompasses a very diverse range of subjects (anything from health, math, science, business, charisma, etc.) that are not doubt, interesting to hackers.
I would go a step further and say that what hackers today have in common with Bīrūnī is that the diverse subjects he was most interested in were somehow overlapping with one another.
