Traditional engineering textbooks are substantially limited by approaches relying on analytical solutions where most of the applications are described by differential equations without simple analytical solutions. An alternative is to design a textbook around computer-program-based simulations, where the simulations progressively evolve through…

Materials science--the science of stuff--has made our lives better by making it possible for manufacturers to supply us with products. Students have misconceptions about materials use. Many may think using bottled water, for example, is harmless because they recycle the plastic empties, but they fail to consider the resources and energy used to…

Structured databases of chemical and physical properties play a central role in the everyday research activities of scientists and engineers. In materials science, researchers and engineers turn to these databases to quickly query, compare, and aggregate various properties, thereby allowing for the development or application of new materials. The…

Almost everything people have ever done has involved materials. Historical evidence indicates that "engineered materials" have been available and utilized for the benefit of humankind since the Neolithic period, beginning about 10,000 BC. Some of these materials have been in existence for thousands of years. At first, materials consisted of wood,…

The separation of content between science, math, engineering, and technology education should not exist. Working with the relationship between these content areas enhances students' efforts to learn about the physical world--and the Bungee Jump offers one great way to go about it. This article describes an activity called the Egg Bungee Jump which…

Plastic baggies, especially the sealable variety, seem to be a ubiquitous part of human culture. The zipper-type seal on plastic baggies is an example of an unappreciated engineering accomplishment that is relevant to everyday life. In fact, the challenge of fastening two pieces together probably dates back to the making of tools and clothing by…

Chemists continue to work at the forefront of materials science research. Recent advances include application of bioengineering to produce plastics from renewable biomass instead of petroleum, generation of paper-based batteries, and development of phototriggerable microcapsules for chemical delivery. In this article, the author provides summaries…
