You may not want to do it now but you can plan for the future. Tell your neighbors about your savings and trade CFL replacement tips You may be surprised to find that they've already replaced all of their incandescent bulbs too, or that they found a bulb for that fixture you all have...
Heat is the most common way we see light being generated -- a normal 75-watt incandescent bulb is generating light by using electricity to create heat. Electricity runs through a tungsten filament housed inside a glass sphere. Because the filament is so thin, it offers a good bit of resista...
To make a darker tint, the lenses are simply left in the liquid longer. In the next few sections, we'll take a look at other sunglass technologies. Polarization Light waves from the sun, or even from an artificial light source such as a light bulb, vibrate and radiate outward in all...
I think science is fascinating because it helps me to make sense of the world around me and understand how things work. I think so many things can be explained by science. Example, you know, the four seasons, how the temperature changes, and how a light bulb works, and how...
