Magnification (Power) And Using Eyepieces . ... To determine power in a telescope, divide the focal length of the telescope by the focal length of the eyepiece. By exchanging an eyepiece of one focal length for another, you can increase or decrease the power of the telescope. For example, a 25mm eyepiece used on a telescope with a 1000mm focal length would yield a power of 40x (1000 / 25 = 40) and a 10mm eyepiece used on the same telescope would yield a power of 100x (1000 / 10 = 100). ...

... I was six years old when I discovered I had the power of Zeus. By merely dragging my feet across a wool rug in my house, I could unleash lightning bolts -- well, some tiny sparks, at least -- on my mortal parents. ... Do you not believe that you, too, can make mini-lightning? ... When Nature works on larger scales like those of big, fluffy clouds in the atmospheres of Earth or mighty Jupiter, the sparks are even bigger, and the energy is enormous. ...

... It was discovered during 1970's that radiation from electrical power transmission lines is one source of whistler-mode waves in the magnetosphere . Most of the world's power systems use 50 Hz or 60 Hz, but their harmonics in the kHz range (due to mechanical imperfections, nonlinear loads, etc.) can be radiated by transmission lines and leak into the magnetosphere with sufficient intensity to stimulate wave growth and emission generation, much like the VLF transmitter signals. ...
