1. The development of MRI imaging technology is one useful spinoff of basic research into structure of the atom. Research‚ however‚ is expensive. Many people argue that high cost of research outweighs its potential benefits. Provide one argument for and one argument against increasing current funding for atomic-structure research. Use specific examples from this lesson in your answer to support each position. (6 marks) Answer: 2. The emission spectrum of an unknown element contains two lines-one

BAND THEORY OF SOLIDS According to quantum free electron theory of metals‚ a electron in a metal experiences constant(or zero) potential and free to move inside the crystal but will not come out of the metal because an infinite potential exists at the surface. Bloch Theorem: According to this theorem‚ the periodic potentials due to the positive ions in metal have been considered. (i.e. the electrons moves in a periodic potential provided by lattice). If the electron moves through these ions‚

.Physics is the field of scince that controls the Earth‚ the Moon‚ the Sun and the Universe It is the science of matter and its motion‚ space-time and energy. Physics describes many forms of energy - such as kinetic energy‚ electrical energy‚ and mass; and the way energy can change from one form to another. Everything surrounding to us is made of matter and Physics explains matter as combinations of fundamental particles which are interacting through fundamental forces. It will not be an exaggeration

1.) One argument for continuing research is that it helps diagnosis injuries and prevent further damaging if diagnosis are early. Not only is this benefit for the patient but it may save the health care system more money as the patient would not need to go for more costly medical treatment if diagnosis are caught early. On the other hand‚ an argument agasint continuing research is that the cost are increasing at an alarming rate (such as the Large Hadron Collider (LHC)‚ the average person may not

In the year 1803‚ Thomas Young first introduced the idea of trichromatic color representation. Young proposed that we have three “particles” in the eye that are each sensitive to a specific range of visible light that allows us to see color. Years later‚ Hermann von Helmholtz continued Young’s theory. Helmholtz suggested that the three different “particles” were categorized by their response the different wavelengths of light that hit the retina. Today‚ we know that the “particles” that Young and

AgentWorld COEN 166/266 Overview AgentWorld is a simulated natural environment‚ populated with competing agents‚ vegetation‚ and predators. Agents can consume vegetation (when it is blooming) to increase their energy level. An agent’s energy level will also decrease over time based on their activity. Invocation When the “simworld” executable is run‚ each of the environments in the Environments directory will be run in succession. Each time that an environment simulation is run‚ it is populated with

The Military’s Pandora’s Box by Dr. Nick Begich and Jeane Manning This article was prepared to provide a summary of the contents of a book written in 1995 which describes an entirely new class of weapons. The weapons and their effects are described in the following pages. The United States Navy and Air Force have joined with the University of Alaska‚ Fairbanks‚ to build a prototype for a ground based "Star Wars" weapon system located in the remote bush country of Alaska. The individuals who

Our AdvoCare Story AdvoCare was introduced to us by my good friend Jenny Donnelly. She said she and her husband were stay-at-home parents‚ making a full-time plus income on a part-time basis with AdvoCare. At first Wayne was very skeptical‚ but finally tried the products. He felt an dramatic increase in energy from day one on products and lost 3+ inches off his waist in just 3 weeks on 24 Day Challenge Program‚ 8 years later‚ he has a body fat percentage under 10% and what he calls "Superman
