13 things that do not make sense
New Scientist has a brilliant article about 13 things that do not make sense -- phenomena that are in defiance of conventional wisdom in the fields of physics, chemistry and biology.
Of the thirteen, perhaps the most intriguing is the tale of the NASA space probes that are accelerating due to some unknown force:
"The resulting acceleration is tiny, less than a nanometre per second. That's equivalent to just one ten-billionth of the gravity at Earth's surface, but it is enough to have shifted Pioneer 10 some 400,000 kilometres off track...So what is causing it?"
