How does electricity work? (Lansing State Journal, December 08,1993) Electricity or electrical energy, is produced at a power plant. Different types of plants generate electricity in different ways. Oil, coal, and natural gas fuel most power plants. These fuels are burned, and the heat given is used to boil water. When water boils, the high pressure steam produced can physically propel electrical generators. These generators are simply large magnets that spin with respect to c ...

A Lightning PrimerPage 2 Introduction Lightning, the thunderbolt from mythology, has long been feared as an atmospheric flash of supernatural origins: the great weapon of the gods. The Greeks both marveled and feared lightning as it was hurled by Zeus. For the Vikings, lightning was produced by Thor as his hammer struck an anvil while riding his chariot across the clouds. In the East, early statues of Buddha show him carrying a thunderbolt with arrows at each end. Indian tri ...

Coulomb Force With the study of electricity, we begin a qualitatively different phase of our study of physics. Up to now, we have for the most part dealt with topics which are macroscopic, and of which we have some intuitive appreciation. For the next few chapters, we will be concerned with the microscopic world, which is largely hidden from our senses and our common sense. So far, most of the forces, pressures and stresses we have studied have been communicated by direct contact: I lean on t ...

Electricity in the Woodshop (Revised) A comprehensive discussion of electrical issues for Woodworkers and Do-It Yourself homeowners. By Rick Christopherson. This article was originally written for woodworkers who run into the occasional electrical question, but it has grown in such popularity over the past 10 years that it is being referenced by a broad range of groups, ranging from Electrical Engineers to women's support groups. The content is easy to understand, but also gracefully delves into the deeper technical aspects. The article begins with an easy to understand explanation of electricity, and then branches off into several different subtopics at varying levels complexity.

advanced search Number 269 (Story #3), May 6, 1996 by Phillip F. Schewe and Ben Stein HOLOGRAM TEMPLATE FOR ATOMS . Physicists at NEC (Japan) and the University of Tokyo have invented a rudimentary form of lithography using atoms instead of light waves to produce an image. The researchers reconstruct a desired pattern at a detector by using a computer-generated hologram (essentially the Fourier transform of the pattern recorded in a silicon nitride membrane) to manipulate a beam of cold neon atoms. Cold enough to act as waves (with a quantum wavelength of 7.1 nm), the atoms were diffracted at the hologram and deposited onto a fluorescent plate. (J. Fujita et al., Nature, 25 April 1996.)

Rami Arieli: "The Laser Adventure" Chapter 10 Section 4, page 9 Applications of Holograms in Anti Forgery - Identification Since recording holograms requires special equipment and conditions, holograms can be used to help prevent forgery of important documents. Holograms are used on credit cards, identification documents, classified documents, valuable merchandise, and even banknotes. These holograms are usually rainbow holograms, which can be viewed at white light. After making the master hologram, duplicating the holograms in many copies is very cheap. Thus, it helps prevent forgery, and does not add a lot to expenses.

Rami Arieli: "The Laser Adventure" Chapter 10 Section 4, page 10 Applications of Holograms in Art Holograms are very attractive visually. Creating holograms enables adding many special effects to the images. There are many museums showing holograms created by artists, and many products containing holograms are sold (Pictures, stickers, toys etc.). The art of holography is developing rapidly, as the price of laser drops down. As new cheap diode lasers are developed, and their properties improved, they are starting to be used for creating holograms. In the past the coherence length of diode lasers were very poor, but in 1997 many scientists report using them for holography. New cheap holographic recording materials, developed in Russia, are entering the market recently.

Rami Arieli: "The Laser Adventure" Chapter 10 Section 3, page 17 Rainbow Hologram - Benton Hologram The second method of creating white light holograms use interference in 2-D but based on two recording stages. This is the method used to create the holograms on credit cards, magazines, and other commercial products to prevent forgery. These holograms look in colors that depend on the viewing angle. The physical basis of this method is to reduce the amount of information on the hologram. ...

University of Maryland Computer Tutorials in Physics: Electric Forces I. Introduction When we developed the laws of classical mechanics we learned that to determine what forces acted on an object we had to look for forces of two types: touching (contact forces) and non-touching (action-at-a- distance forces). Our main example of a non-touching force was gravity. The earth exerts a force on an object, pulling it towards it, even when the object does not touch the earth. A second non- ...
