The difference between a rocket and a jet
By: Dave Jackson
The aircraft piston engine approached its limits of horsepower and mechanical complexity during World War Two. The development of rocket and jet engines enabled enormous advances in aviation and aeronautics. Rocket and jet engines were both developed with military aviation in mind (although original goals...

The first thought of flight started with Nostradamus , who in fifteen-0-three to fifteen-sixty-six, drew plans to the first helicopter known to man. His inovation sparked the world's thought of flight to be witch craft and just another sourcerer trying to conquer the world. In ninteen-0-one...

The ability to fly has fueled the imagination of inventors, engineers, artists and poets for centuries. Leonardo DaVinci studied the principles of flight and devised the first architectural blueprints for the earliest helicopter. The Wright Brothers stood on the dunes of Kitty Hawk and watched...
The basics of acoustics
By: Megan Rogers
First off, what is acoustics? Acoustics is the study of sound and how different things (like temperature) affect it. There are, of course, a million and one things that affect the way sound waves travel, but let's just cover the basics, which is essentially how...

Few of us with a drivers licence would not be aware of the horrific statistics describing automobile accidents and while causes are often a combination of circumstances leading to the conclusion speed plays a dominant role in the severity of any given vehicle accident. Large...
Understanding projectile motion
By: Douglas Black
How often do we neglect the intricacy of simple things like motion? Sure, just about everything on our planet moves to some degree, but what about objects that are given that extra little push to get going. According to the laws of motion nothing moves...

The major magnetic field on planet Earth is the one which comprises the North Pole and the South Pole. By hanging a piece of magnetite, a rock with the properties of a magnet, from a string, the rock turns until it points north and south...

It is a testament of engineering that a machine weighing hundreds of thousands of pounds can fly just as gracefully as a single engined Cessna. Such an accomplishment is the result of countless discoveries going right back to Sir Isaac Newton and Mr. Bernoulli. These...

Did you know Boeing wasn't one hundred percent sure the 747 could fly until it actually did? It was faith in physics that reassured the engineers (and bankers) that such a massive undertaking was worth the risk. Physics describes four basic elements involved with flying...
How airplanes fly
By: Douglas Black
Humans are by nature explorers, seeking to extend ourselves beyond what we can see with the naked eye. In the beginning only birds were able to grace the crystal blue skies overhead, but this temporary limitation was only a matter of time and science. Flight...
