      Electroluminescent Wire

      Electroluminescent wire (EL wire) is a thin wire that produces 360 degrees of visible light. EL wire differs from string lights, such as Christmas lights, which only produce light at specific points. It uses a phenomenon known as electroluminescence to generate light when electricity runs through it. EL wire is very thin and flexible and

    • What is Malleability?

      What is Malleability?

      Malleability refers to metals’ (and other hard materials’) ability to be stretched, shaped, or molded through applied pressure. While not all objects are malleable, most metals are. This is the reason that metals such as gold, silver, and platinum, are used to make jewelry and electronic circuits. Malleable objects can usually be reshaped and molded

    • 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

    • What is a Pitot Tube?

      What is a Pitot Tube?

      A pitot tube measures pressure levels in liquids. They are most commonly seen in laboratory settings but can be seen in industrial applications as small cylinders. While a pitot tube is not the only device that measures fluid pressure, it is capable of being implemented in much more diverse environments than similar devices. How Pitot

    • 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

    • Pulse Induction Metal Detectors

      Pulse Induction Metal Detectors

      Metal detector technology has been used for a number of decades to locate various metallic artifacts and precious metallic ores. An uncommon, but accurate metal detector is the Pulse Induction Metal Detector. It uses Pulse Induction Technology to find metals. What is Pulse Induction Technology? In Pulse Induction technology, a coil is used as a

    • What is a Laser Profilometer?

      What is a Laser Profilometer?

      A profilometer is an instrument that measures a surface profile to determine its roughness. A surface’s vertical resolution is normally measured at the nanometer level, with lateral resolutions being measured to a less accurate degree. Over the past decade, profilometers have started using laser technology in order to improve the degree to which a surface

    • 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 Are Bucky Balls Used For?

      What Are Bucky Balls Used For?

      A bucky ball is a fullerene molecule which is any molecule that is made up entirely of carbon. Specifically, a bucky ball is a spherical fullerene while the cylindrical fullerene is called a carbon nanotube. They were discovered in 1985 and are referred to, chemically, as C60. When they were discovered, it expanded the number

    • How Does Sound Travel?

      How Does Sound Travel?

      Sound is characterised as a series of waves that move through a particular medium. A medium is some sort of a subtance–whether it be water, plasma, air, a solid, or anything else–that these waves move through. The waves cause the particles in this substance to vibrate which is how the sound is potentially heard. A
