Cryogenics and the Future Cryogenics is a study that is of great importance to the human race and has been a major project for engineers for the last 100 years. Cryogenics‚ which is derived from the Greek word kryos meaning "Icy Cold‚" is the study of matter at low temperatures. However low is not even the right word for the temperatures involved in cryogenics‚ seeing as the highest temperature dealt with in cryogenics is 100 (C (-148 (F) and the lowest temperature used‚ is the unattainable

What is so super about superconductors? Perhaps the fact that superconductors are materials that have no resistance to the flow of electricity. So they basically will conduct electricity without resistance when the material is at a very cool temperature. Resistance becomes undesirable because it produces losses in the energy flowing through the material. Resistance creates heat which is why‚ when the material is cooled‚ the resistance will no longer be an included factor in the flow of electricity

The two men procured a loan of 1‚000 pounds from a local bank and established the Swallow Sidecar Company in 1922. While Walmsley focused on building the company’s sidecars‚ Lyons concentrated on hiring labor‚ renting a working place‚ and advertising. Soon the company was garnering a reputation for its sidecars‚ which were used during

and francium. They are collectively known as the alkali metals. These are so called because they form hydroxides on reaction with water which are strongly alkaline in nature. The elements of Group 2 include beryllium‚ magnesium‚ calcium‚ strontium‚ barium and radium. These elements with the exception of beryllium are commonly known as the alkaline earth metals. These are so called because their oxides and hydroxides are alkaline in nature and these metal oxides are found in the earth’s crust*. Among
