    A noteworthy solar system event will occur next Monday: a solar transit by Mercury. Although Mercury’s close approaches to Earth, known as inferior conjunctions, occur often (approximately once every 116 days), Mercury passes across the disc of the Sun as viewed from Earth much more rarely, because of the 7° inclination of Mercury’s orbit to the ecliptic, Earth’s orbital plane. The transit on Monday will be the fourth of only 14 Mercury transits this century.

    The last week before Labor Day and the start of fall classes is a traditional week for vacations at Columbia – indeed the entire university administration is rumored to be away – and I have followed this tradition. Nonetheless, the pace of science is not slowed markedly by the summer getaways of scientists (or administrators), as the following news attests.
