      How Do Neurons Communicate?

      Neurons communicate by sending electrical signals throughout the body. The exact process is an electrochemical one and the speed in which neurons communicate is so fast that seeing someone drop out of someone's hand and trying to grab for it–a process that requires the image to get into the brain, processed and then a signal

    • How Do Light Bulbs Work?

      How Do Light Bulbs Work?

      The light bulb, invented in 1854, has been a crucial component of civilization since. Contrary to popular belief, the light bulb was invented by Henricg Globel, a German watchmaker, not Thomas Edison. Edison did improve on the idea of the incandescent light bulb, though, and strived to make it better. Due to the works of

    • Silicone Grease

      Silicone Grease

      Silicone grease is made when a thickener is combined with silicone oil in order to create a waterproof grease. The most common thickener used to make this grease is amorphousfumed silica with polydimethylsiloxane as the silicone oil. The resulting mixture is a translucent, viscous, white paste that has lubrication properties depending on the exact formula

    • What is a Fullerene?

      What is a Fullerene?

      A fullerene is a third form of the carbon molecule that falls in between graphite and diamond. It was named for Richard Buckminster Fuller, who was well known for geodesic dome designs whose appearance closely resembled spherical fullerenes. A Fullerene’s carbon atoms may be arranged in a cylindrical, ellipsoid, or spherical form. The spherical fullerenes

    • How Does Solar Energy Work?

      How Does Solar Energy Work?

      Solar energy is created by taking sunlight (solar thermal energy) and converting it into electricity. This conversion takes place via a medium that absorbs the solar energy and then converts it into usable electricity that can power various objects that are electrically operated. While the solar panel is not the most effective method of generating

    • Law of Universal Gravitation

      Law of Universal Gravitation

      The law of universal gravitation gives the attraction force between two objects due to gravity. Definition: For any pair of objects, they attract each other with a force that is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between their centers of mass.

    • Liquid Armor

      Liquid Armor

      Liquid armor is a new development in the body armor field. It is a material that makes lightweight, flexible and tough body armors possible. Body Armor Body armor is a protective clothing designed to stop bullets or bomb fragments and shrapnel from penetrating the human body. They are descended from leather or metal armor designed

    • Pulse Induction Metal Detectors

      Pulse Induction Metal Detectors

      Metal detector technology has been used for a number of decades to locate various metallic artifacts and precious metallic ores. An uncommon, but accurate metal detector is the Pulse Induction Metal Detector. It uses Pulse Induction Technology to find metals. What is Pulse Induction Technology? In Pulse Induction technology, a coil is used as a

      How Do Microwaves Work?

      In the modern world, virtually everyone owns a microwave oven. How many people, though, stop to consider what exactly microwave ovens do or how they work? To anyone who has been alive over the past few decades, microwave ovens are as normal as anything else; to someone born even a century ago, however, they would

    • How Overhead Projectors Work

      How Overhead Projectors Work

      Overhead projectors work with the help of transparencies. All data are printed on top of the transparencies. Before starting up, be sure to have a socket with live electricity where you can switch the overhead projector. The power buttons are usually made of first class plastic, the “click” sound is heard; it means it has
