      Petabyte

      A petabyte is a measurement unit that describes a piece of information that is equal to 1,000 terabytes or one quadrillion bytes of data. A single petabyte is equal to 1,000,000,000,000,000 bytes . When a petabyte describes computer memory, it is also used in reference to a corresponding power of 1024. The approved scientific symbol

    • Augmented Reality

      Augmented Reality

      Augmented reality is one of the newest innovations in the electronics industry. It superimposes graphics, audio and other sense enhancements from computer screens onto real time environments. Augmented reality goes far beyond the static graphics technology of television where the graphics imposed do not change with the perspective. Augmented reality systems superimpose graphics for every

    • What is Anthracite Coal?

      What is Anthracite Coal?

      Anthracite coal is a form of coal that is almost made entirely of carbon. Anthracite coal is much harder than other forms of coal such as bituminous, and is usually found in areas surrounding mountains or deep valleys. Anthracite burns much cleaner than other forms of coal due to its low pollutant content. In fact,

    • What Are the Four Dimensions?

      What Are the Four Dimensions?

      The four dimensions are concepts in mathematics to describe different shapes. It is easy to understand a first dimension, second dimension and third dimension shape. All things are 3D in the world, but images can be 2D. A first dimension is as easy as a line. However, what is the fourth dimension? The fourth dimension

    • Electromagnets

      Electromagnets

      Electromagnets are magnets whose magnetic properties come from or are generated through electricity. A magnet is a material (this is usually metal), which has at least one pair of negative and positive poles. These opposite poles' attraction produces a magnetic field. This gives the magnet the ability to 'attract' metals such as iron or steel.

    • Angular Acceleration

      Angular Acceleration

      Angular acceleration is the rate of change of a body’s angular velocity compared to time. It is considered a vector quantity since it has a direction and magnitude. Angular acceleration is similar to linear acceleration except that it travels on an arc. Scientifically, it is equal to (final angular velocity – initial angular velocity) /

    • How Do Electric Motors Work?

      How Do Electric Motors Work?

      As society is trying to slowly ween itself off of oil-dependency, the search for alternative fuels continues. One source of alternative "fuel" that already exists, however, is the electric motor. Electric motors are commonly found in vehicles, toys, and other electronic devices but there is still a campaign to improve the quality and efficiency of

    • 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

    • 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

    • DNA Fingerprinting

      DNA Fingerprinting

      DNA fingerprinting is the process of taking a cell sample from a person and analyzing it. This technique involves analyses of less than 0.1% of human DNA (which is different for each person). Though small, this 0.1% of DNA is enough to distinguish one individual from another and can be used to determine maternity/ paternity
