      ESR Spectroscopy

      ESR Spectroscopy (Electron Spin Resonance Spectroscopy or Electron Paramagnetic Resonance Spectroscopy) is a technique used for studying chemical species that have one or more “free radical” or unpaired electrons. Most stable molecules only have paired electrons without any free radicals, so ESR Spectroscopy is used less often than NMR (Nuclear Magnetic Resonance) Spectroscopy, the usual

    • 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

    • Vibration Measurement

      Vibration Measurement

      Vibration measurements are made in order to identify when preventive or corrective repairs are required on machinery. These repairs are made in order to reduce or eliminate the noise that damaged equipment make. This prevents catastrophic failure of the equipment. Vibration measurements are frequently made on process control equipment and rotating machinery such as the

    • Who Discovered Quantum and Particle Physics?

      Who Discovered Quantum and Particle Physics?

      During the nineteenth century the main theory in physics was still Newtonian Mechanics. With the advances in electricity, magnetism and the studies about light, it was clear that the theory had its limitations. The limitations appeared in the limits of the too small (atomic size) or the too fast (light speed). The study of the

    • How Thunderstorms Form

      How Thunderstorms Form

      There are three stages to a thunderstorm’s life cycle: the cumulus stage, the mature stage, and the dissipation stage. When a thunderstorm begins to form, it does so at the cumulus stage. From there, the storm advances in severity until it reaches its peak at the mature stage and then begins to gradually die out

    • What Causes Typhoons?

      What Causes Typhoons?

      A typhoon is nothing more than a hurricane that occurs in the North West Pacific Ocean. The same conditions that cause a hurricane in the Atlantic ocean that hit the United States every summer are the ones that cause a typhoon. However, a typhoon does have a series of specific “rules” to exist and therefore,

    • What is Magnesium Used For?

      What is Magnesium Used For?

      Magnesium is a chemical substance denoted by the symbol Mg. It forms part of the Group 2 of the periodic table, thus making it an alkaline earth metal. Its atomic number is 12 and it is considered to be the 8th most copious element found in the earth’s crust. In terms of the human body,

    • Boltzmann Constant

      Boltzmann Constant

      The Boltzmann Constant (Boltzmann’s Constant) is a fundamental physics constant that plays a pivotal role in almost every single statistical formulation in both quantum and classical physics. It is named after Austrian physicist, Ludwig Boltzmann (1844 – 1906), who made significant contributions to the foundation and development of a particular branch of theoretical physics known

    • 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

    • 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
