... Bad Astronomy . ... Every few months, one of a series of questions comes up on the USENET group sci.astro involving tides, or the rotation of the Moon, or the recession of the Moon from the Earth. ... Why the Moon's rotation period is the same as the length of time it takes to orbit the Earth (same as number 1, but phrased differently). ... But when this happens, the time it takes for the Earth to rotate once will be slowed to exactly the same time it takes for the Moon to go around the Earth once! ...

Computers become more and more popular nowadays. That means that the amount of people who are able to work with computer programmes and play computer games has increased. In many cases computer games are the only thing that a person is accustomed to. ... As a result of this epidemic "homo playing" may put on the isoreality helmet which makes a person, crazy about games, forget about food, slumber and all other components of real life: "homo playing" becomes isolated from community. ...

... It is kept running by a periodic timer interrupt generated by PC hardware. If the system has too many processes running, it may take too long to service the timer interrupt, and the software clock starts slipping behind. ... If you boot your computer often (as is the case for most systems that aren't servers), it will usually keep fairly accurate time. ... By running one these commands regularly, your computer will keep as accurate time as the remote computer. ...

... Cost­E#ective System Management Skip Schaller Steward Observatory, University of Arizona, Tucson, AZ 85721 Abstract. Quality system management of computer workstations for as­ tronomy can be achieved with relatively small manpower requirements, if the right cost­e#ective administrative design decisions are made. ... The system is designed so that one doesn't depend on four or more hosts, (such as a software server, cpu server, data file server, font server, etc.) to get work done. ...

... Before the modern era of technological astronomy, to know anything about the Universe beyond our planet we relied on light. ... Historically the two rival ideas were that light was either a stream of tiny bullet-like particles or a wave wobbling its way through space. ... The light we see (visible light which is not the tautology it sounds) is only part of the electromagnetic spectrum, a great sweep of radiations which also includes radio, infra-red, ultra-violet, x-rays and gamma rays. ...

... Kepler's Laws . ... Second Law . 12a. More on 2nd Law . ... Kepler's 2nd law prescribes the way the velocity V of an object orbiting a single center varies around its orbit: . The rate at which the line to the center ("radius vector") covers area does not change around the orbit." As noted in section #12 , this means that the object's velocity V increases when its distance r decreases, and vice versa. ... Because by Kepler's 2nd law, the Earth moves in its orbit a little faster in winter. ...
