Retaking exam

Four college students missed an important exam, choosing to party instead. They go together to their professor the next day, and said, "We're sorry we missed the exam. We had a flat tire on the way to class. Is there any way we could possibly take a re-test?"

"Sure," replied the professor. "Come on in tomorrow, and you can all take a retest. But remember, it's a pass or fail."

The four students arrived the next day to take the retest, and all of them sat down in their seats. Before handing them their exams, their professor told them, "I've got good news and bad news. The good part is, there's only one question on the test. The bad news is, if any of you fail, you all fail the test."

The students sat there, a bit worried from this professor's strange introduction to the exam. Then the professor handed out the four exams, and each student stared down at their papers, which contained just one simple question:

"Which tire was it?"

Hermann Minkowski

Died 12 Jan 1909 at age 44 (born 22 Jun 1864). German mathematician who developed the geometrical theory of numbers and who used geometrical methods to solve difficult problems in number theory, mathematical physics, and the theory of relativity. By 1907, Minkowski realised that the work of Lorentz and Einstein could be best understood in a non-euclidean space. He considered space and time, which were formerly thought to be independent, to be coupled together in a four-dimensional "space-time continuum". Minkowski worked out a four-dimensional treatment of electrodynamics. His idea of a four-dimensional space (since known as "Minkowski space"), combining the three dimensions of physical space with that of time, laid the mathematical foundation of Albert Einstein's general theory of relativity.
