A linear particle accelerator is a large device that can speed up electrons, ions, or other particles and slam them into a target in order to release subatomic particles and radiation. Sensors then record these by-products, send their data to a central computer system that creates a digital, 3D image of the particle, and labels …
A magnetic levitating vehicle (MagLev) is a vehicle that uses a strong electromagnetic field to resist gravity and keep the vehicle floating out of the ground. The technical name is Electromagnetic suspension. The principle of the Electromagnetic suspension is to charge with the same pole the base of the vehicle and the rail with a …
Magnetic propulsion is the act of moving an object with magnetic fields and a flowing electrical current. The current is used to manipulate the system’s magnetic field or charge a fluid in the system that can be repelled. The Lorentz force then pushes the conductor in a direction that is perpendicular to the magnetic field …
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 …
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 …
Vulcanized rubber is a material that undergoes a chemical process known as vulcanization. This process involves mixing natural rubber with additives such as sulfur and other curatives. Vulcanization makes rubber much stronger, more flexible, and more resistant to heat and other environmental conditions. Vulcanized rubber makes both soft and hard objects, ranging from rubber bands …
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 …
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 …
Refractometers measure the refractive index of liquids, gases, and translucent solids such as gemstones. The measurement of how much the speed of light is reduced when traveling through a gas, solid, or solution is referred to as the refractive index. When the device is used to test liquids, it typically measures the salinity, fluid concentration, …
Quasars are a phenomena that, to this day, continue to baffle and confuse astronomers. There are different theories. One is that a quasar is formed from a super, massive black hole. Another theory is that a quasar is actually a baby galaxy and is at the earliest stages of development. However, since no one really …
