    • Infrared


      Infrared light is a form of electromagnetic waves. In its visible form, infrared can be seen as red or violet. Visible infrared waves are very short, measuring about 750 nm in length; longer infrared waves which are closest to microwaves are about 1mm in length. Infrared Waves While most infrared wave lengths give off heat,

    • Electromotive Force

      Electromotive Force

      Electromotive force is the electrical potential energy that causes current to flow through a circuit. It results from the difference in charge between two points in a material. This difference is created when an external source such as a battery makes electrons move to both points so that there is an excess at the first

    • Anodizing Aluminum

      Anodizing Aluminum

      Anodizing/anodized aluminum refers to both a specific type of aluminum alloy as well as the process that is used to produce this alloy. The term “anodizing” is used to describe a technique for expanding the natural oxide layer of metals, especially aluminum. Anodizing changes the texture of aluminum by creating a much more porous surface

    • What Causes Radioactivity?

      What Causes Radioactivity?

      Radioactivity is caused when an atom, for whatever reason, wants to give away some of its energy. It does this because it wants to shift from an unstable configuration to a more stable configuration. The energy that is released when the atom makes this shift is known as radioactivity. In other words, radioactivity is the

    • 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

    • Zettabyte


      A zettabyte describes a unit of data or information that is equal to 1,000,000,000,000,000,000,000 bytes. The term is equal to a billion terabytes and the symbol ZB represents it. Zebibyte (ZiB) describes a measurement of data using the power of 1024. A single zettabyte is equivalent to 1,024 exabytes and is used prior to the

    • What Are Air Scrubbers?

      What Are Air Scrubbers?

      An air scrubber is a device that removes particles, gases, or chemicals from the air in a specific area. Air scrubbers are very important in some industries as workers are frequently exposed to harmful substances. Most air scrubbers are made for a specific type of air purification but some are made to handle particles, gases,

    • Fresnel Lens Projector

      Fresnel Lens Projector

      A projector is able to accomplish a projection with the help of a combination of lenses along with the other technical things. A Fresnel lens projector is one which has different Fresnel lenses placed in the projector. Fresnel Lens Fresnel lens was invented by a French physicist, Augustin-Jean Fresnel. These lenses have a large aperture

    • How Do Nuclear Power Plants Work?

      How Do Nuclear Power Plants Work?

      A nuclear power plant works in the same way that a coal power plant works. Heat is generated which causes water to turn into steam. This steam turns a turbine which causes a generator to spin which generates electricity. However, a nuclear power plant does not use coal. Instead, the fuel of choice is uranium

    • What is an Ultrasonic Fogger?

      What is an Ultrasonic Fogger?

      An ultrasonic fogger is a device that uses ultrasonic sound waves to break water into millions of individual water droplets that are then sprayed into the air as a thick fog. Ultrasonic foggers are most often used for Halloween decorations as a dry ice replacement. The fog that an ultrasonic fogger produces is not created
