This web-based software teaches the user concepts about pericyclic reactions. In the software, there are a Baker's Dozen of practice problems in Pericyclic Mechanisms. Each of the problems is intended to take between 1-3 hours to solve. The software contains answers to all of the problems. The following is a typical example of the type of questions asked in this software: "When compound 1 is heated, a transient intermediate 2 is formed, rapidly rearranging to two new compounds 3 and 4. An aqueous workup of this mixture, in which traces of acid were present, showed that 4 had been converted to 5. Suggest structures for compound 2-4, and mechanisms for all the steps in this sequence." This software was originally cataloged at http://www.my-edu2.com/eduframe.htm.   less

This web-based software informs the user about women advancing sciences. Actually, how long have people been active in science? The answer is the same for both women and men -- as long as we have been human. One of the defining marks of humanity is our ability to affect and predict our environment. Science - the creation of structure for our world - technology - the use of structure in our world - and mathematics - the common language of structure - all have been part of our human progress, through every step of our path to the present. Women and men together have researched and solved each emerging need. Today we define a scientist as someone who usually has a Ph.D. and works in a technical field. This person is a specialist in a narrow field of research, and often is well trained in only that field. Today's Ph.D. shows special aptitude and creativity in a particular discipline and rarely shows the same talent outside that discipline. Today's science has a large set of separate disciplines: astronomy, mathematics, physics, biology, chemistry, and the social sciences, all in various combinations.

Analytical chemistry is the science of making quantitative measurements. In practice, quantifying and analyzing a complex sample becomes an exercise in problem solving. To be efficient and effective, an analytical chemist must know the tools that are available to tackle a wide variety of problems. For this reason, analytical chemistry courses are often structured along the lines of the analytical methods (the tools-of-the-trade). Understanding the analytical toolbox requires a scientist to understand the basic principles of the analytical techniques. With a fundamental understanding of analytical methods, a scientist faced with a difficult analytical problem can apply the most appropriate technique(s). A fundamental understanding also makes it easier to identify when a particular problem cannot be solved by traditional methods, and gives an analyst the knowledge that is needed to develop creative approaches or new analytical methods. Analytical chemistry requires a broad background knowledge of chemical and physical concepts. These hypermedia tutorial documents contain links to the fundamental principles that underlie the different analytical methods. As you study the analytical chemistry topics, follow the hyperlinks to the basic concepts with which you are not familiar or with which you need a refresher. Studying the fundamental concepts will reinforce your understanding of both the analytical techniques and the underlying principles.   less

This web-based software teaches the user concepts about an effective algorithm for computing the numerical range using MATLAB. In this software, we collect a few fairly well known facts about the numerical range and assemble them into an effective algorithm for computing the numerical range of an n x n matrix. Particular attention is paid to the case in which a line segment is embedded in the boundary of the numerical range, a case in which multiplicity is present. The result is a parametrization of the curve that forms the boundary of the numerical range.
