      Terahertz Radiation

      Terahertz radiation is a selection of the electromagnetic wave spectrum that propagates at frequencies regarded as the terahertz band. ‘Radiation physics of energetic waves’ defines the terahertz band as tremendously high frequency. The terahertz band can be applied within the bracket of 300 gigahertz (high frequency microwave) and 3000 gigahertz (long wavelength far infrared light).

    • 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) /

    • 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

    • Humidity Sensors

      Humidity Sensors

      Humidity sensors (hygrometers) measure and report the air’s relative humidity. They are used in homes, wine cellars, and working environments that that are so humid that they negatively impact working conditions. Humidity sensors are also used in vehicles, industrial HVAC systems, and meteorological stations to help in the predicting and reporting of weather conditions. How

    • What is Transconductance?

      What is Transconductance?

      Transconductance is a property of some electronic components and is also known as mutual conductance. It is the opposite of resistance. The measure of transconductance is the ratio of the electrical current change at an output port as compared to the voltage change at the input port. The measure of transconductance is commonly used in

    • 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

    • 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

    • Torsional Vibration

      Torsional Vibration

      Solid mechanics defines torsion as the twisting of an object as a result of applied torque. Torsional vibration can be broadly described as the angular vibration of any object. It can be defined specifically as the periodic motion corresponding to a shaft, where the shaft is twisted about its axis, alternating from one direction to

    • Antigravity Propulsion

      Antigravity Propulsion

      True antigravity propulsion involves using a material or technological effect that counteracts the effects of gravity without using aerodynamic lift, electromagnetism, or some other balancing force. Likewise, antigravity does not refer to situations in which an object or person experiences lack of weight such as being in a pool, free fall, or high altitude orbit.

    • Seebeck Effect

      Seebeck Effect

      The Seebeck Effect was first discovered in 1821. It describes the thermoelectric phenomenon that results when the temperature differences between dissimilar metals in a circuit are converted into electric current. This is one of three similar processes that relate to conductivity, temperature, and thermoelectricity that was discovered in the 1800s. The Thomson Effect was first
