      Future Combat Systems

      Military experts believe that future wars will not be huge battles for territory as had happened in the past but rather small insurgencies spread over a wide area such as what eventually happened in Iraq. Thus, rather than a large force with heavy equipment that will take weeks to assemble and deploy, the US Army

    • How Hurricanes Form

      How Hurricanes Form

      Hurricanes are caused by immense low pressured formed over the warm oceans in the summer and early fall months. With this low pressure, water vapor is evaporated off of the ocean surface. This water vapor releases the latent heat of condensation which causes all of the water to begin forming into clouds. This condensation forms

    • 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

    • What Causes Volcanoes?

      What Causes Volcanoes?

      A volcano is typically found where two or  more tectonic plates are either converging or diverging. The result is a rupture in the surface of the planet which then allows hot ashes, gas, and volcanic lava to rise up from the magma chamber located underneath the Earth’s surface to the atmosphere. Some of the common

    • Examples of Kinetic Energy

      Examples of Kinetic Energy

      Kinetic energy is the energy of motion. It is also referred to as energy in motion, or as the work required to take an object from being at rest to action/movement. Mathematically, kinetic energy is calculated as ½ of the mass of a body, multiplied by the speed of the body squared, KE=1/2 mv^2. Where

    • Long Distance Wireless Power Transmission

      Long Distance Wireless Power Transmission

      Simple wireless power transmission works because of the principles of magnetic resonance and magnetic induction. This power transmission system relies on two coils in range with each other and resonating at the same frequency. The coils need to be in range because the magnetic field of the source must be strong enough for the receiving

    • What Causes Left Handedness?

      What Causes Left Handedness?

      Left handedness is a person's preference in using the left hand over the right hand which, when considering the number of people, is relatively rare. It is believed that anywhere from seven to ten percent of the adult population is left handed. The rest are predominately right handed. The fundamental problem when discussing left handedness

    • What is a Generator?

      What is a Generator?

      A generator (electrical) is a device that converts mechanical or chemical energy into electrical energy. Generators often use motors, turbines, engines, cranks, pistons, or other sources of mechanical energy. Likewise, generators may use chemicals or other materials that produce electricity when mixed or ignited. Generators do not produce electricity itself, but simply produce a flow

    • How a Laser Cutter Works

      How a Laser Cutter Works

      A Laser cutter is a machine that uses a laser to cut materials. The Laser Cutter works by making the laser enter through the side of the material that needs to be cut and shoots it through the axis of the beam. If a cut needs to be made and there are no edges near

    • How a Fuel Cell Works

      How a Fuel Cell Works

      A fuel cell is a device that produces electrical energy through chemical reaction. This energy conversion process is known as electro-chemical energy conversion. The simplest form of electrochemical device that we use in our day to day life is a battery cell. A fuel cell is different from a battery cell in so far as
