Hi! I'm looking for a digital camera...I want to take pictures from a large distance clearly, its colors to be lucid and to perform well if i take pictures at night. What would you suggest me to buy? As regards price don't worry...Give me your options and i will choose the one that better suits me. Thank you!
Answer
I would suggest Nikon D5000 DSLR camera.It take outstanding image quality, especially in low light and difficult lighting situations

or if you want point & shoot camera I would suggest Canon Powershot SX10IS 10MP with 20x Wide Angle Optical Image Stabilized Zoom.It take good shot whether the action is fast or slow, close up or far away

and another good choice ony Cybershot DSC-HX1 9MP with 20x Optical Zoom with Super Steady Shot Image Stabilization and 3.0 Inch LCD.It use G lenses that are used in top of the line DSLR cameras and advanced pro-sumer HD Camcorders.Superb picture quality

How is a pendulum used for time keeping? On what mechanism is time keeping based in clocks without a pendulum?
Answer
You may be able to produce a time track for an event by using a camcorder with a clock in the background (with a continuous seconds sweep hand and a suitable distance scale for reference).
A pendulum clock keeps exact time because a pendulum swings at a precise time interval because of its length under the action of gravity. The pendulum bob constantly converts potential energy (of height) to kinetic energy (of motion) at the top and bottom of each swing, respectively. An escape mechanism permits the clock to add back a tiny amount of energy from a weight and pulley each swing to make up for energy lost due to friction and wind resistance. A separate weight and pulley actuates the chimes.
Electric clocks use electric motors that rotate a precise amount each minute, etc. when supplied with 60 cycle electricity. Power stations must keep track of the total cycles each day and add or subtract a few cycles as necessary to keep all clocks running together (except when there is a power loss!).
Windup clocks use a powerful spring to store energy and an escape movement to slowly release the energy driving the clock mechanism. The escape movement may include a rotating hair spring that oscillates back and forth at an accurately regulated pace.
