Synthetic polymers make excellent specimens for light microscopy. Despite this, the use of the technique, at least in its advanced forms, is not so widespread as might be expected. Although reliable and relevant data are difficult to find and quantify, it seems that in other fields of materials science and technology there is a greater readiness to tum to the microscope in research, in industrial problem solving, or for quality assessment and control. It also seems that the reasons for the...

At some point during the last 100,000 years, humans began exhibiting traits and behavior that distinguished us from other animals, eventually creating language, art, religion, bicycles, spacecraft, and nuclear weapons—all within a heartbeat of evolutionary time. Now, faced with the threat of nuclear weapons and the effects of climate change, it seems our innate tendencies for violence and invention have led us to a crucial fork in our road. Where did these traits come from? Are they part o...

This volume discusses the mineral resources upon which modern civiliza tion is built. Take away these minerals and humanity will rapidly return to the stone age, with its greatest concern the depletion of flint (also a mineral). It would, of course, result in about a 99% reduction in population. In other words, approximately 99% of the worlds' population is dependent on minerals for its existence. That is a pretty strong statement, but how many have even seen a travois? Without minerals, p...

In recent years there has been a rapid increase in the understanding of communication between animals and this is perhaps especially true of bio-acoustics. In the last 35 years a completely new branch of bio acoustics, involving ultrasounds, has been made possible by technical developments that now allow these inaudible sounds to be detected and studied. This subject has a personal fascination for the authors, perhaps because of the novelty of 'listening in' to these previously unknown sig...
