Egg" is a story of persistence, love for one's work and is just plain funny! The story starts out with Clifford Stoll being "recycled" to a computer analyst/webmaster. Cliff, as he is affectionately called, is a long-haired ex-hippie that works at Lawrence Berkeley Lab. He originally was an astronomer, but since his grant wore out, he became a mainframe master. He was glad that instead of throwing him out into the unemployment office, the Lab recycled their people and downstairs he went, to the computer
A Book report on “The Cuckoo’s Egg” by Cliff Stoll A Cuckoo’s Fledgling Although the 1980s are not generally thought of as a decade of innocence, there were, however, a few pockets of juvenile utopia. One such example was the rapidly expanding “online” community, with its assortment of up-and-coming networks that were, to many technically inclined users, a virtual “McDonald’s Play Place” with slides, ball pits and winding tubes to explore, all rapped in a security blanket of innocence. Not until
non-metal at any range of temperatures and pressures. That is, until now. Recently this year, hydrogen was changed into a metallic substance, which could conduct electricity. An experiment conducted by William J. Nellis et al. at the Lawrence Livermore National Laboratory accomplished this feat. Hydrogen was converted from a non-metallic liquid, into a liquid metal. The likelihood that the most abundant element in the universe could be converted into metallic form at sufficient pressures was first theorized
Nature or Nurture Every human being is unique. Were we destined to be the way we are, or have we been made this way through our environment and experiences? Psychology has long been debating the issue of Nature versus Nurture. Characteristics such as hair and eye color are generally recognized to be controlled by genetics. Those on the Nature side (Nativists) claim that genetics control much more, including personality and character. Nurture backers (empiricists) will argue that a person’s environment
for this testing is the DYNA3D which was developed at Lawrence Livermore National Laboratory (A Gift of Fire, Baase). DYNA3D is a computer simulation program that models the interactions of physical objects on impact such as vehicle impacts involving roadside structures such as signs, supports, guardrails and crash cushions. DYNA3D, suitable for solving problems involving rapid change, has had many applications in safety analysis. Laboratory analysts have used DYNA3D to study crashworthiness in
For centuries, tornadoes have been a destructive force of nature that possesses the power to destroy cities and take people’s lives. Recently, a new epidemic of tornadoes has been ravaging America which draws the question, is global warming to blame? With up to 300 mile per hour winds and damage paths can go up to one mile wide and 50 miles long, they truly are Mother Nature’s weapon of mass destruction. Tornadoes are formed typically during a front of stormy weather known as a supercell, although
Global Warming Blown Out of Proportion The United States by no means should consider complying with the Kyoto Protocols. My conviction in the negation towards passing this bill is that the whole Global Warming idea is highly blown out of proportion by politicians and the mass media. Global warming, as it may exist in the most gentle form, is the result of natural changes and could yield positive benefits. It is a predictable, quantifiable process. Thus the Kyoto plan is flawed in many ways
In America, income inequality has shown to be a rising problem in the past five years. Most of America is affected by this, however the ones that are not, continue to make more money. In short, the poor is getting poorer and the rich is getting richer. As a result of America’s economic problem, the middle class has been struggling and many Americans can relate, including me. Because of America’s economy, an important social class is diminishing and causing major issues in families across the nation
Fuel of the Future It is obvious that this country has a knack for vast and rapid consumption of oil. Increases in greenhouse gas emissions, global warming threats and surging gas prices are just some of the warning signs. In the last two decades, this country has made great bounds in new, energy efficient technologies that have played a major role in the United States’ energy conservation efforts. “It’s not about turning off the lights or unplugging the refrigerator. It is a story about
The discovery of fission occurred during a time of great turmoil. Two German physicists then later verified by two Jewish refugee physicists discovered it. Italian Physicists Enrico Fermi later discovered the unique quality of fission that was induced by neutrons but also produced neutrons. This created the idea of a self-sustaining chain reaction, and the large amount of energy found within a nucleus was now accessible at a large scale (Nuclear weapons section, para 1). Nuclear weapons are categorized
However since fluorine-18 is unstable it must decay to form a positive beta particle (or positron) and an oxygen-18. This is done inside the human body as the Fluorine and pharmaceutical accumulate in the tumour. The positron will then travel a short distance losing energy before combining with a free electron which therefore annihilates them, producing 2 gamma rays which will be used to detect where the FDG has accumulated. Technetium is a commercial radioisotope produced in the OPAL reactor
Hydrogen gas was first identified as an element in 1766, by British scientist Henry Cavendish, in an experiment wherein he separated hydrogen gas by reacting zinc metal plates with hydrochloric acid. Cavendish found that when he applied a spark to the resulting hydrogen gas, it yielded water. It wasn’t until some years later that French chemist Antoine Lavoisier gave hydrogen its modern name. The word hydrogen is derived from the Greek words ‘hydro’ and ‘genes’, which translate as ‘born of water
The Molten Core Theory The center of the Earth is composed of a solid metallic core surrounded by a molten layer of liquid metal. This paper will discuss the reasons to believe the theory that the Earth has a molten core, and the important discoveries that have led to this generally accepted theory. It is very reasonable to agree with this theory when paying credence to the logical evidence that answers questions about the Earth’s core. This evidence includes information about the elemental

Finally, a third design is being developed by the Lawrence Livermore National Laboratory in California. This design, called Induct rack, aims to lift and propel the train without constant electrical energy being used in the track or the train. This design uses special arrangements of permanent magnets on the train and
For the next eight years were some of the best times this country had ever seen. The 1980s is now a time of economic conditions leaders still try to attain today. The standard of living in the United States improved, along with the feeling of national pride. After four repugnant years under Jimmy Carter, Ronald Reagan took this country to the standard that it was capable of. As promised during his campaign, the first thing Ronald Reagan completed after taking office was ending the price control
revolution in wireless communication systems. They would be pervasively present from something as small as a sensor sensing the electrical charge in a chip to radars tracking the storms, and system monitoring and maintaining the heath of Electric Grids at national level. They are different from existing embedded systems, by direct interaction with the physical world and complexly networked nature. An embedded systems are characterized by the presence of microcontroller, actuators and embedded code running

Compact Flourescent Lamp and the Environment Abstract Technological advances have come a long way since the incandescent light bulb. Today, the compact fluorescent lamp (CFL) is the most energy efficient light bulb on the market. In the beginning, consumers had resistance toward the CFL. With governmental support in establishing energy-efficient lighting programs, the CFL have been able to stay in the market and improve throughout the years. Introduction With the advances in technology
Document clustering is the process of organizing a particular electronic corpus of documents into subgroups of similar text features. Previously, a number of statistical algorithms had been applied to perform clustering to the data including the text documents. There are recent endeavors to enhance the performance of the clustering with the optimization based algorithms such as the evolutionary algorithms. Thus, document clustering with evolutionary algorithms became an emerging topic that gained
