    • What is a Plasma Cutter?

      What is a Plasma Cutter?

      A plasma cutter is a device that directs an ionized gas at an object under extreme temperatures. Plasma cutters are often used for industrial purposes, such as cutting metal, and are dependent on plasma, an extremely hot state of matter. Plasma cutters are essentially a type of plasma torch meant for cutting metal rather than

    • 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

    • What Are the Five States of Matter?

      What Are the Five States of Matter?

      There are five states of matter that occur when physical forces are applied to them. These states are fairly easy to understand when their physical properties are observed. Depending on the type of matter that is being dealt with, the state of the matter may be more difficult to reach when applying these physical stressors. The best way

    • Electroluminescent Wire

      Electroluminescent Wire

      Electroluminescent wire (EL wire) is a thin wire that produces 360 degrees of visible light. EL wire differs from string lights, such as Christmas lights, which only produce light at specific points. It uses a phenomenon known as electroluminescence to generate light when electricity runs through it. EL wire is very thin and flexible and

    • How Do X-Ray Machines Work?

      How Do X-Ray Machines Work?

      The Parts of an X-Ray Machine There are three main parts of an x-ray machine. The first is the x-ray tube. This is responsible for the creation of x-rays. Therefore, without this functioning properly, there would be little chance for the x-ray to work in the right way. It generates enough x-rays so that when

    • How to Disable Onstar

      How to Disable Onstar

      Disabling Onstar is not a task that is as simple as pushing a button. Onstar is a device that permits the vehicle to be tracked and, if something happens to the vehicle, allows an operator to conact the vehicle. For some people, there is discomfort with Onstar having the ability to track the vehicle. To

    • Transmission Electron Microscope

      Transmission Electron Microscope

      The transmission electron microscope (TEM) is a scientific instrument that uses electrons instead of light to scrutinize objects at very fine resolutions. They were developed in the 1930s when scientists realized that electrons can be used instead of light to "magnify" objects or specimens under study. TEMs provided a means to go beyond the magnification

    • What is a Goniometer?

      What is a Goniometer?

      A goniometer is a device that either measures an angle or moves an object along a fixed point to a specific angular position. Goniometers have many uses and can be found in a number of industries. They measure range of motion, determine direction, and measure an object’s dimensions. Goniometers are relatively simple in design and

    • Weather Modification Technology

      Weather Modification Technology

      Weather modification refers to willful manipulation of the climate or local weather. Research done in this field goes back to as far as the early 1940s when the US military experimented with cloud seeding to stimulate rain. Today, private corporations have joined the weather modification research effort to protect people, cities and assets from the

    • How Do Ocean Currents Affect Climate?

      How Do Ocean Currents Affect Climate?

      Ocean currents are one of the main factors that affect climate. Other factors are proximity from the equator, distance from the sea, direction of prevailing winds and relief (mountains). But, for the most part, ocean currents act as one of the most important factors that influence the climate. And the reason why is because a
