High schools

One of the most commonly used constructs is a model. A model is a simple way of describing and predicting scientific results, which is known to be an incorrect or incomplete description. Models might be simple mathematical descriptions or completely nonmathematical. Models are very useful because they allow us to predict and understand phenomena without the work of performing the complex mathematical manipulations dictated by a rigorous theory. Experienced researchers continue to use models that were taught to them in high school and freshmen chemistry courses. However, they also realize that there will always be exceptions to the rules of these models. 

In the spring of 1989, it was announced that electrochemists at the University of Utah had produced a sustained nuclear fusion reaction at room temperature, using simple equipment available in any high school laboratory. The process, referred to as cold fusion, consists of loading deuterium into pieces of palladium metal by electrolysis of heavy water, E)20, thereby developing a sufficiently large density of deuterium nuclei in the metal lattice to cause fusion between these nuclei to occur. These results have proven extremely difficult to confirm (20,21). Neutrons usually have not been detected in cold fusion experiments, so that the D-D fusion reaction familiar to nuclear physicists does not seem to be the explanation for the experimental results, which typically involve the release of heat and sometimes gamma rays. 

An idea of the possibilities is given by the old high-school chemistry experiment with sulphur crystals ("flowers of sulphur"). A 10 ml beaker is warmed up on a hot plate and some sulphur is added to it. As soon as the sulphur has melted the beaker is removed from the heater and allowed to cool slowly on the bench. The sulphur will... 

The viewpoint of this book is first that most of the students who elect to receive some training in air pollution will have previously taken courses in chemistry at the high school or university level, and that those few who have not would be well advised to defer the study of air pollution until they catch up on their chemistry.

Hans Bethe, an only child, was horn on July 2, 1906, in Strasbourg, when Alsace was part of the Wilhelminian empire. His father was a widely respected physiologist who accepted a professorship in Frankfurt when Hans was nine years old his mother was a gifted musician who was raised in Strasbourg where her father had been a professor of medicine. The high school Bethe attended in Frankfurt was a traditional Humanistisches... 

During his next four years as an ETH student, Einstein did not excel in regular course attendance, relying far more on self-study. In 1900 he passed his final examinations with good grades, which qualified him as a high school teacher in mathematics and physics. For the next two years he had to be satisfied with temporary teaching positions until in June 1902 he was appointed technical expert third class at the Patent Office in Berne. 

The purpose of this publication is to provide an up-to-date reference guide for people who want full, current, trustworthy information about all aspects of energy. This includes individuals who want more information than they read in newspapers or magazines, high school and college students who want information for class discussions and papers, people looking for expert information on which to base their everyday energy-related decisions, and scholars who want a review of interdisciplinary research. 

Second, Max Dresden, who was both my thesis advisor and loyal friend. As Jay was the perfect teacher of high school physics, so Max was the quintessential physics professor. Max opened my eyes to the deej) mystery we call the universe, and taught me that the path to truth is indistinguishable from the path to beauty. The seminal idea and outline of this book-its major themes, chapters, and overall organization -benefitted greatly from Max s experience and wise counsel. I have followed our bible of ideas ever since Max and I lovingly crafted a skeletal version of it prior to our first meeting with a potential publisher over a decade ago. 

Element 101 is named Mendelevium in honor of the great Russian chemist, Dmitri Mendeleev. The youngest of seventeen children, he was born in Tobolslca where his grandfather published the first newspaper in Siberia and his father ivaj the high school principal. Dmitri received his early education from a political exile, but when his father died, his mother traveled west in search of better educational opportunities for Dmitri. 

How richly this prophecy has come true is read in the scientific literature of organic chemistry. His first major success was the synthesis of quinine, a problem he began worrying as a high school student. This compound was to be typical of the difficult molecules he has successfully...
