      Quantum

      A quantum is the most basic physical unit that is involved in any type of interaction. For example, a quanta (plural) is the transfer of different energy particles such as photos and bosons when discussing matter. Because of the Latin of the word quantus meaning "how much," it can be concluded that when discussing quantum,

    • Radiometric Dating

      Radiometric Dating

      Radiometric dating is a process of identifying the age of a material based on known half-lives of decaying radioactive materials found in both organic and inorganic objects. Radiometric dating is often used to determine the age of rocks, bones, and ancient artifacts. In fact, radiometric dating can be used to determine the age of the

    • How Sand is Formed

      How Sand is Formed

      Sand is a sedimentary material; loose grains of worn out and disintegrated rocks. Sand is of fine granules with grains ranging between 0.06 and 2.0 mm in diameter. Sand is a naturally occurring fragmented material comprised of tiny particles of decomposed rocks, shells, or corals. So how does sand come about? As mentioned before, nature

    • Holographic Memory

      Holographic Memory

      Holographic memory is a storage device that is being researched and slated as the storage device that will replace hard drives and DVDs in the future. It has the potential of storing up to 1 terabyte or one thousand gigabytes of data in a crystal the size of a sugar cube. Brief History of Holographic

    • How a Laser Printer Works

      How a Laser Printer Works

      A laser printer unlike an inkjet printer uses a laser light beam for printing operations. It is also distinct from other printers because of its exceptional printing speed as well as highly accurate rendering. It utilizes a xerographic (a process of creating an image by the action of light on a specifically coated charged plate)

    • 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.

    • U.S. Drones

      U.S. Drones

      The U.S. drone program has seen significant press since the first Gulf War when the defenders of Faylaka Island surrendered to the Pioneer drone, or Unmanned Aerial Vehicle (UAV), flying spotting services for the USS Wisconsin (BB 64). Since that time, the technology powering U.S. drones has steadily improved now allowing the MQ-1B Predator and

    • Magnetic Separators

      Magnetic Separators

      A magnetic separator is a device that uses a magnet to remove impurities and other magnetic materials from metal. Magnetic separators can be used before, during, and after production of a material and can be adjusted to attract different types of magnetic materials at varying levels of intensity. Magnetic separators are used for a wide

    • What Are Photonic Crystals?

      What Are Photonic Crystals?

      Photonic crystals are those that manipulate how photons are absorbed or reflected off of them. They occur in nature and are made of dielectric nanostructures that allow certain wavelengths to pass through them while blocking other wavelengths. The visible light portion of the electromagnetic spectrum’s wavelengths is responsible for colors, therefore photonic crystals can spontaneously

    • How Laser Skin Treatment Works

      How Laser Skin Treatment Works

      A laser skin treatment is a relatively new technology that surgeons have only recently begun using. It is when the surgeons utilize lasers (containing carbon dioxide) to vaporize the skin’s upper layers, consequently allowing a new layer of skin to form. The technique is commonly used to fine tune wrinkles and various face lines, especially
