Ionic solids are, by virtue of their very nature, inevitably both hard and brittle. The way in which ions are attracted to one another makes this development an inevitability, resulting in some rather common structures that we we see every…

Modern science has developed several different types of nuclear reactors to produce electrical power. Most of these produce energy when a critical mass of highly radioactive enriched uranium is accumulated. Within the reaction chamber nuclear particles fly about, striking each…

The clock paradox is more often referred to as the twin paradox. It, like all paradoxes in science, comes about due to a lack of applicability of a theory to a particular experiment. The twin paradox is based on the…

There are several methods for testing for the presence of lead in everyday materials and some of these are listed below.  Firstly, it is important to point out that lead can be dangerous to humans, when present in high quantities,…
