Metacognitive Miscalibration, or wicked problems and the desire to learn, and other reasons misinformed people think they are well-informed.

Changes in mass distribution affect the earth’s rotation rate. A little.

The National Institute of Standards and Technology in Boulder, Colo., occasionally adds a “leap second” to the atomic clocks used to standardize time. The last such update took place on January 1, 2006.
