How to Calculate the Force of Gravity on the Earth ?

Gravity : Starting with the physics equation for the force of gravity, you can plug in the mass and radius of the Earth to calculate the force of gravity near the surface of the Earth. The equation for the force of gravity is F = (Gm1m2) /r^2 and it holds true no matter how far apart two masses are. The gravitational force between a mass and the Earth is the object’s weight. Mass is considered a measure of an object’s inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: Fg = mg. Kilograms and slugs are units of mass; newtons and pounds are units of weight. You can use Newton’s law of gravitation…

Energy Efficient Lighting – LED

LED - Energy Efficient Lighting Electric lighting burns up to 25% of the average home energy budget. The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself. Light Emitting Diode (LED) and Compact Fluorescent Lights (CFL) bulbs have revolutionized energy-efficient lighting. CFL are simply miniature versions of full-sized fluorescent. They screw into standard lamp sockets, and give off light that looks similar to the common incandescent bulbs - not like the fluorescent lighting we associate with factories and schools. LED are small, very efficient solid bulbs. New bulbs are grouped in clusters with diff user lenses which have broadened the applications for the use in the home. these technology is advancing rapidly, with many new bulb styles available. Initially more expensive than…

How to determine Golden Ratio – 1.618 ?

Golden Ratio                      The golden ratio (symbol is the Greek letter "phi" shown at left) is a special number approximately equal to 1.618It appears many times in geometry, art, architecture and other areas.   The Idea Behind It We find the golden ratio when we divide a line into two parts so that: the whole length divided by the long part is also equal to the long part divided by the short part Beauty   This rectangle has been made using the Golden Ratio, Looks like a typical frame for a painting, doesn't it? Some artists and architects believe the Golden Ratio makes the most pleasing and beautiful shape. Do you think it is the "most pleasing rectangle"? Maybe you do or don't, that is up to you! Many buildings and artworks have the Golden Ratio…
