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 …
The light bulb, invented in 1854, has been a crucial component of civilization since. Contrary to popular belief, the light bulb was invented by Henricg Globel, a German watchmaker, not Thomas Edison. Edison did improve on the idea of the incandescent light bulb, though, and strived to make it better. Due to the works of …
Parabolic mirrors are specially shaped in order to capture and focus energy onto a single point. They also distribute energy from a single point outwards. The mirrors are a specific paraboloid type that is rotated around its axis, and is also known as a circular paraboloid. Parabolic mirrors are also referred to as parabolic reflectors …
A tsunami is formed when there is an earthquake, volcanic eruption or, more rarely, a landslide underwater. Typically, neither the earthquake, eruption or landslide are felt because they are so deep under water. However, the actions that have taken place are the first steps that lead to a massive tsunami that can cause tremendous damage …
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 …
Potassium Perchlorate (Potassium Chlorate (VII), perchloric acid, potassium salt, peroidin, and KClO4) is an inorganic salt that is used as a strong oxidizer. The function of potassium perchlorate’s oxidizer trait really depends on the chemical use. Potassium Perchlorate can be found in the following common items: Fireworks – Fireworks have many chemical compounds inside them, …
A Virtual Autopsy or Virtopsy is a new and non-intrusive form of performing an human autopsy. This system utilizes a Computer Tomography or CT unit and an (MRI) Magnetic Resonance Imaging unit to obtain a detailed view of a body. Here the MRI images and the detailed X-rays are combined to create a full three-dimensional …
Augmented reality is one of the newest innovations in the electronics industry. It superimposes graphics, audio and other sense enhancements from computer screens onto real time environments. Augmented reality goes far beyond the static graphics technology of television where the graphics imposed do not change with the perspective. Augmented reality systems superimpose graphics for every …
A rotameter is a device that measures the flow rate of a liquid or gas in a tube. Karl Kueppers invented the rotameter in 1908, which has been widely used since then for a variety of applications. Rotameters are included in a class of devices known as “variable area meters” that depend on the substance …
Luminol is a substance that has a blue or green glow when it comes in contact with blood, certain metals, or other oxidizing agents. It is made from hydrazine and hydrogen peroxide and exhibits chemiluminescence, the process by which light is emitted from a chemical reaction. Luminol has many uses, but is most widely used …
