"We have come full circle," O'Brian says. The rotation of the Earth had long been the most accurate measure of time for humanity, but now such technologies as atomic clocks and GPS devices make it possible to measure tiny variations in Earth's rotation. And the scientific reverberations are not just for space junkies. In a July paper in the journal Nature, for instance, researchers in England and France argued that sub-millisecond-scale variations in Earth's rotation that occur on a 5.9-year cycle are probably linked to motions and interactions within the planet's molten core where no one has ever been to take a look.

The Iowegian wants readers to think about the solicitation ordinance that will prevent groups or individuals from entering a roadway to solicit money. The Centerville City Council in June by a 5-0 vote passed the first reading of just such an ordinance. Public pressure and during a subsequent special meeting, the council voted 3-2 to table the ordinance. A second special meeting to discuss the solicitation ordinance is scheduled for 5:30 p.m. Thursday, Aug. 7 at City Hall. So, the question of the week is, "Do you or do you not support the ordinance to prevent solicitation of funds in city streets?"

A. I support the ordinance
B. I do not support the ordinance
C. Not sure
