The radio spectrum is the lower portion of the electromagnetic spectrum. The radio spectrum is below both the infrared spectrum and the visible spectrum. The sections of the radio spectrum are called bands. These bands are subdivided into frequencies and even further divided into channels...

The radio spectrum is an integral part of every life on Earth. Every time a person makes or receives a telephone call using a cellular device, that person uses a small segment of the radio spectrum. Using a microwave oven, remotely changing the channel on...

"What's the go o' that?" and "Show me how it doos!" are just two of the common outbursts which served to stimulate young James Clerk Maxwell's curiosity about the way things worked. When he was older, his curious nature would lead him to...
An introduction to the fourth state of matter: Plasma
By: Matt Bird
Liquid, solid, gas. Most high school graduates will be able to tell you at least a bit about each of these three states of matter, as they're all fairly common occurrences in the natural world. We drink liquids, we eat solids, we inhale gases. Simple...

Speaking at the at the British Science Festivalin Guildford, Professor Colin McInnes of Strathclyde University explained his work at the leading edge of deep space propulsion technology. He described how solar forces can be divided into two types: solar wind, which is produced by protons...

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...

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...

Entropy: The Second Law of Thermodynamics Entropy is intrinsic within the laws of nature and physics. It can be described as thus: that the order of things within the world, deteriorates over a period of time. In fact, the universe, as we know it...

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...

While twenty first century Quantum mechanics is highly abstract and counter-intuitive it’s not that difficult to glean a fundamental understanding of this branch of modern physics by following its history. If we alter our usual ways of thinking that is because our adaptive thinking...
