    • The Kelvin Scale

      The Kelvin Scale

      The Kelvin Scale is a thermometric scale used in physical science to describe the absolute temperature of an object, substance, or area. While Fahrenheit and Celsius scales measure temperature, the Kelvin Scale defines temperatures relative to an object’s thermodynamic movement. As a result, the Kelvin Scale does not use degrees, but simply a number followed

    • What is the Fifth State of Matter?

      What is the Fifth State of Matter?

      The fifth state of matter is actually the first phase of matter. It is called a Bose-Einstein Condensate. Matter in the fifth state is really slow moving and extremely condensed. It only exists at near absolute zero temperatures and is very fragile and unstable. It was discovered in 1995 by Eric Cornell and Carl Weiman through experimentation with rubidium,

    • Dielectric Constant

      Dielectric Constant

      A dielectric constant measures the extent that a material concentrates electrostatic flux and is also known as the relative static permittivity, static dielectric constant, and relative dielectric constant. It is essential when determining if a substance can be used in a capacitor or various chemistry and physics applications. A material’s dielectric constant value must be

    • What is Bioluminescence?

      What is Bioluminescence?

      A living organism is bioluminescent when it produces and emits light. Most organisms that do this live in the sea. However, there are several land insects and plants that also have bioluminescent qualities, including the firefly. The trait has typically evolved in organisms that either need to communicate with each other or lure/detect prey. How

    • Eddy Currents

      Eddy Currents

      Eddy currents are also referred to as Foucault currents and are created when conductors are exposed to a changing magnetic field because of a field source’s relative motion. Their applications include induction heating and non-destructive testing. Eddy currents are continually researched in order to develop new applications. How do Eddy Currents Work? Eddy currents are

    • What is Magnetic Wire?

      What is Magnetic Wire?

      Magnetic wire is a copper or aluminum wire that produces an electromagnetic field when wrapped into a coil and connected to a power supply. It is used in a number of applications and is a vital component in many different devices. Magnetic wire can be used in electrical to electrical, electrical to mechanical, and mechanical

    • What is Stereolithography?

      What is Stereolithography?

      Stereolithography is a recently discovered process by which products, especially prototypes, can be constructed one layer at a time by using UV-curable photopolymer resins and a UV laser. While stereolithography cannot create every type of material, it produces a wide variety of products for testing, analysis, or review. Stereolithography can be used for a wide

    • What is a Peltier Cooler?

      What is a Peltier Cooler?

      A Peltier Cooler or Peltier Heat Pump is a type of refrigerator that has no moving parts and is capable of transferring heat to either side of itself. Peltier Coolers are advantageous as they are solid state devices and only require a DC electrical current in order to cool an object or area. A Peltier

    • What is Microfarad?

      What is Microfarad?

      The term microfarad is used to describe a unit of capacitance that is 0.000001 farad. The symbol that represents a microfarad is µF. It is commonly used in utility alternating-current and audio frequency circuits. The capacitors that are found in them normally have a rating of 1 µF or more. However, even smaller capacitors are

    • The Peltier Effect

      The Peltier Effect

      The Peltier effect is one of the three separately identified effects to which “Thermoelectric Effect” or simply, “Thermoelectricity” refers. The other two are the Seebeck and Thomson effects. Discovery This effect is named after French physicist Jean-Charles Peltier, who discovered it in 1834. Peltier found that the junctions of dissimilar metals were heated or cooled
