A college in Massachusetts has changed all of the speed limit signs on campus to honor a retired mathematics professor. When he retired, Professor David Kelly asked that the speed limit be changed to 17 mph instead of 15 mph because he had spent his entire career fascinated by the number 17. Kelly had been at the school for 45 years, and said he would forego a retirement party if the school changed the signs. Kelly said he feels the tribute captures the unique quality of the school. He knows a lot about the number 17, which is the seventh prime number. Kelly said there are many fun facts about 17, including that there are 17 columns on the long side of the Parthenon in Greece.—Jim L. Wilson and Jim Sandell
