According to SR, Newton was more-or-less right about how objects move at ordinary speeds: that’s why his theory was successful for so long, and why it continues to be useful. But SR comes into its own when accounting for the surprising behaviour of objects moving near the speed of light (300 000 kilometres per second, or 186 000 miles per second). Despite ignoring gravity, SR in its turn is usu...
Someone thinks of a number between one and one million (which is just less than 2). Another person is allowed to ask up to twenty questions, to each of which the first person is supposed to answer only yes or no. Obviously the number can be guessed by asking first: Is the number in the first half-million? and then again reduce the reservoir of numbers in the next question by one-half, and so on...
BACKGROUND Civilian suicide rates vary by occupation in ways related to occupational stress exposure. Comparable military research finds suicide rates elevated in combat arms occupations. However, no research has evaluated variation in this pattern by deployment history, the indicator of occupation stress widely considered responsible for the recent rise in the military suicide rate. METHOD T...
100 000 quinacrine nonsurgical female sterilizations have been completed over the past decade involving transcervical insertion of quinacrine (252 mg) as pellets by one, two or three monthly insertions. No deaths have been reported and serious complications are far fewer than for surgical sterilization. Sideeffects are mild and transient. Efficacy has improved from 3 pregnancy failures per 100 ...
