The team which found that neutrinos may travel faster than light has carried out an improved version of their experiment - and confirmed the result. If confirmed by other experiments, the find could undermine one of the basic principles of modern physics. Critics of the first report in September had said that the long bunches of neutrinos (tiny particles) used could introduce an error into the test.

Jon Stewart Doesn’t Understand How Science Works Even a Little Bit What Is Science? From Feynman to Sagan to Asimov to Curie, an Omnibus of Definitions
We have examined the behaviour of two simple differential equations so far, one for population growth, and one for the radioactive decay of a substance. The methods we have developed are actually useful for many other interesting problems, and can help us to make predictions about other systems that, at first sight, do not seem at all related. We will find that the common thread in all these systems is the simple differential equation of the form
