      What is Hindsight Bias?

      Hindsight bias is when people exaggerate their confidence in an event that occurred based on predictions that were made prior to the event’s occurrence. Hindsight bias is just one type of bias that the brain uses to store and recall information. This is because people tend to focus on an event that occurred rather than

    • Nanopollution


      Nanopollution refers to the waste matter or byproducts of nanoscopic device or material manufacture. Nanoscopic device or material manufacturing processes leave behind nanoparticles (smaller than a billionth of a meter) which can infiltrate the cells of humans, animals and all living organisms that may be unprepared for the influx of artificial particles. A 1941 study

    • Air Exchangers

      Air Exchangers

      An air exchanger is a device that transfers stale air from inside a home to outside, and fresh air from outside to the inside. Air exchangers are often large and built directly into a home’s foundation in order to provide maximum fresh air levels at all times. This is important because indoor air is often

    • 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

    • Long Range Acoustic Device

      Long Range Acoustic Device

      The LRAD or the long range acoustic device that has been developed by American Technology Corporation is capable of emitting a maximum of 151Db sound within 30 degrees of where the device is pointing. This device can be used as a combatant deterrent weapon or crowd-control device by emitting sounds that are painful to the

    • What Causes Left Handedness?

      What Causes Left Handedness?

      Left handedness is a person's preference in using the left hand over the right hand which, when considering the number of people, is relatively rare. It is believed that anywhere from seven to ten percent of the adult population is left handed. The rest are predominately right handed. The fundamental problem when discussing left handedness

    • Supercavitation


      Cavitation happens when water moves at extremely high speed around an obstruction in its normal flow. This causes the water pressure around the propeller to drop, creating air bubbles which dissolve after a few moments and causing water to rush in on the empty space created previously by the bubbles then crashing against the obstruction.

    • The Coriolis Effect

      The Coriolis Effect

      The Coriolis effect is the tendency for a moving body that is on or above the Earth’s surface to drift sideways from its intended course due to the Earth’s rotation. The direction of drift is to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is because the Earth’s

    • What is Electroluminescence?

      What is Electroluminescence?

      Electroluminescence is the phenomenon where a material emits light when electricity is passed through it. It is one of the greatest discoveries of the twentieth century and other forms of luminescence, including incandescence, chemiluminescence, cathodoluminescence, triboluminescence, and photoluminescence rival it. Electroluminescence generally involves a material producing light without producing heat. It is different from black

    • What is a Karnaugh Map?

      What is a Karnaugh Map?

      A Karnaugh map is a graphical method or shortcut that can be used to solve Boolean algebra problems. Boolean algebra is used to conduct computations and create expressions from two values. This type of math creates the basis behind much of computer science and modern circuit card design today. Maurice Karnaugh created the current version
