- 271: Food Processing
- ... The rays cause whatever material they strike to produce electrically charged particles called ions. Ionizing radiation provides many attributes to treating foods. It has the ability to penetrate deeply into a food interacting with its atoms and molecules, and causing some chemical and biological effects that could possibly decrease its rate of decay. It also has the ability to sanitize foods by destroying contaminants such as bacteria, yeasts, molds, parasites and ...
- 272: Nuclear Power
- ... world s electricity. There are around 316 nuclear power plants in the world that create 213,000 megawatts of electricity. (INFOPEDIA) Radioactive, or nuclear, waste is the by-product of nuclear fission. Fission occurs when atoms nucleus split and cause a nuclear reaction. (General Information) When a free neutron splits a nucleus, energy is released along with free neutrons, fission fragments that give off beta rays, and gamma rays. A free ...
- 273: The Theory of Evolution
- ... a molecule containing 20 of the necessary amino acids that are all the same shape] is . Life - How did it get here states: "the number is larger than the estimated total number of all the atoms in the universe (Life 43,44)! Not only are proteins needed for structure, other proteins are needed as enzymes. 2,000 proteins serving as enzymes are needed to keep one cell alive. The chances of ...
- 274: Manhattan Project
- ... needed for an explosion. Critical mass is the exact amount of fissionable material needed to maintain a fission chain reaction. Once Critical mass was obtained it compressed Plutonium and when the Plutonium was compressed enough, atoms from plutonium were split and it made an explosive bomb that could destroy a medium sized city.3 Security was tight on the Los Alamos site because there was fear that bomb secrets would be ...
- 275: History Of Gunpowder
- ... occurs only in a high order explosive. Detonations are usually incurred by a shock wave that passes through a block of the high explosive material. The shock wave breaks apart the molecular bonds between the atoms of the substance, at a rate approximately equal to the speed of sound traveling through that material. In a high explosive, the fuel and oxidizer are chemically bonded, and the shock wave breaks apart these ...
- 276: Supernovas
- Supernovas A very large star explodes, somewhere in the unfathomable space of our galaxy. The star's core collapses. The monstrous pressure crushes its atoms and smashes their electrons into the nuclei. There, the negatively charged protons change to neutrons and neutrinos. Billions of neutrinos particles, that have no electrical charge and little or no mass, escape through the star ...
- 277: Computers In Society
- ... weighed. However, with our drastic change in technological advances more mediums are transferred through the computer, and the Internet than ever before. The world is getting smaller by the minute. The change of exchange from atoms to bits is irrevocable, and unstoppable. Why now? Because the change is also exponential small differences of yesterday can have suddenly shocking consequences tomorrow. You have probably heard that if you payed an employee a ...
- 278: Diffraction And The Debye-Scherrer Camera
- ... have a very small wavelength. In order for diffraction or interference to occur, the slit widths need to be smaller than the wavelength of the light going through it. Think of a cube that has atoms forming the vertices of a plane. This crystalline structure has many of these atomic planes stacked on top and bottom of each other. Suppose an x-ray beam is incident with an angle of q ...
