... 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! ...

Isaac Newton on the British pound note . ... 1) In the absence of forces, a body at rest will stay at rest, and a body moving at a constant velocity in a straight line continues doing so indefinitely. 2) When a force is applied to an object ("body"), it accelerates in the direction of the force. ... The second law gives an explicit formula, and hence is the one most useful. ... Mach argued that Newton's laws boil down to one law: . ... Mass and force are now readily derived. ...

The vertex system provides a voltage from each motor amplifier that is proportional to the absolute value of the torque. On 19jun02 the dome was moved from 2 degrees za to 19.5 degrees za and back down to 2 degrees za at .02 degrees/second (half slew rate). ... The motors are numbered 11,12,21,21,31,32,41,42 going uphill to downhill. ... When coming downhill, the motors must hold the weight of the dome - the frictional force (the frictional force helps the motors rather than opposing them). ...

Appendix A: Derivation of the Secondary Sag as a Function of Telescope Altitude . One-half of the secondary support structure consists of the two rods shown in Figure 9 plus the opposing rods on the other side of the secondary cage. The total tension force on a single rod can be decomposed into a thermal component and a base tension that is set at the time when the rods are originally tensioned with the turnbuckles. ...

... However to my eye the colour scheme that looks best is what might be described as a `thermal' one, ie one in which cool objects (objects with a long-wavelength excess) are coloured red and hot objects blue, with the intermediate sequence going from red through yellow and white to blue. ... The parameter heat shifts colours along the thermal sequence: at heat = -1 all colours go to red, at +1 they are all blue, with again 0 having no effect. ...
