The Universe is an enormous place. It consists of clusters of galaxies, and in them are stars, solar systems and even the planets. Only 4% of the Universe is ordinary matter (humans, planets and the stars). Some of it (22%) is an unidentified substance known...

There are only a few basic laws of the universe - often so basic that it is hard or impossible to imagine the world without them. One of the most basic laws is the law of entropy, also known as the second law of thermodynamics...

Assaying is the analysis of ore, metal or alloy. The discipline is known as metallurgical assay. There are several uses for assaying metals, both before and after refining it. For example, samples are always taken from potential mines, to be sure of the quality of...
A look at what water on Mars means to astronomers
By: Vicky Ann Smith
The fourth planet in the Solar System, Mars, the red Planet is the closest example to the Earth that we have so far discovered. Its ice caps are similar to ours and prove the presence of water on the ground, this opened up countless possibilities...

What is an inductor? Inductor is a simple electrical component consisting of a coiled wire, a core in its center with certain add-ones depending on its use. When considering its difference from a ‘conductor’ which allows electrical current to flow, inductor would have the...
Galaxies: Types and classifications
By: Vicky Ann Smith
A galaxy is a collection of stars held together by their own gravity and dark matter; we live in the Milky Way galaxy, a spiral disk in space coiling it’s arms outwards. Between 10-14 billion years old, we are believed to be one of...

Inductors are electronic devices which employ the property of inductance. There are actually several different types of devices which fit this description, but all work on the same principle of an induced electromotive force (emf) also referred to as electromagnetic induction, hence the name inductor...
