At times, a mzungu scientist could be chilling in a laboratory and, out of idleness, starts to tinker with this or that. Or begins playing around with specimens, giggling like a lunatic while at it, just for kicks. You know how playful and curious those guys can be! And when he accidentally makes a discovery or ends up with an invention, he not only gets praised and heralded as a genius, but also registered in the Guinness Book of World Records. What's more, he gets showered with lots of money and decorated with a Nobel Prize to boot.
Take, for instance, that hairy dude who accidentally discovered penicillin antibiotics, just by playing around with fungus he had found germinating on dirty utensils he forgot in his kitchen sink while away on vacation. Decades later, Alexander Fleming is still a celeb, just for that accidental discovery.
