      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 an Anechoic Chamber?

      What is an Anechoic Chamber?

      An anechoic chamber prevents sound, radio signals, and electromagnetic waves from echoing  in a room. Anechoic chambers often test antennas, measure the direction of sound, or record music. Anechoic chambers are found all over the world, especially in universities, and can be as large as an aircraft or as small as a car. Full-anechoic chambers

    • What is Magnesium Used For?

      What is Magnesium Used For?

      Magnesium is a chemical substance denoted by the symbol Mg. It forms part of the Group 2 of the periodic table, thus making it an alkaline earth metal. Its atomic number is 12 and it is considered to be the 8th most copious element found in the earth’s crust. In terms of the human body,

    • How Wind Turbines Work

      How Wind Turbines Work

      How a wind turbine works depends on the type of wind turbine discussed. While most people think of windmills as being the only true type of wind turbine, this is simply not the case, as there are horizontal axis, vertical axis, and various other types of "special" wind turbines in service around the world. Horizontal

    • How Do Rockets Work?

      How Do Rockets Work?

      Since the United States first landed a man on the moon, children and adults have been fascinated with how rockets work! Whether one is trying to fly a small model rocket or launching a star ship to rendezvous with the International Space Station, the principles of how rockets work remain the same. Although rocketry has

    • Zettabyte

      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

    • Waste Oil Burners

      Waste Oil Burners

      Waste oil is the term used to refer to any petroleum-based/synthetic oil that is no longer considered usable. This may be due to the presence of excessive impurities, loss of the oil’s original properties, or just from the oil being over-exposed to the elements. A classic problem for society has been how to dispose of

    • 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

    • How a Nuclear Bomb Works

      How a Nuclear Bomb Works

      A nuclear bomb uses a nuclear reaction to generate energy (heat and radiated particles). The energy released is millions or in some cases billions of time stronger than TNT; the whole process is carried out in a very short time, providing huge destructive power. There are two types of nuclear reactions, fission and fusion. During

    • What Are Permanent Magnets?

      What Are Permanent Magnets?

      A permanent magnet (ferromagnet) is a material that produces a magnetic field. Permanent magnets are made from ferromagnetic materials, such as iron, and are created when the material is placed inside of a magnetic field. When the magnetic field is removed, the object remains magnetized. Permanent magnets have a permanent magnetic field and do not
