Hundreds of people flying thousands of feet above the ground is no longer surprising for today's generation. But think of the time when Leonardo Da Vinci could predict the graphical image of modern airplane. It might not be more than a fantastic dream for the...
Can Molecules be Changed to Atoms
By: Steve Lussing
Before I discuss the actual process whereby a molecule can be changed into an atom under specific, and somewhat difficult to achieve laboratory conditions, it should not go unsaid that a single unit of each element as found in nature can be considered to be...

Behind everything that happens around us lie principles that were discovered centuries ago. As human knowledge reaches its peek, almost every action has a scientific explanation just to satisfy man's curiosity. These principles are then applied in everyday life to lighten workloads and as well...

It is wrong to think of space as being completely devoid of anything. The noted Italian astronomer Paolo Maffei has suggested that the density of matter in the deepest regions of space between the galaxies is in the order of about one hydrogen atom per...

Until World War II, the wings on an airplane were generally mounted straight, at a 90 degree angle to the body of the plane. This wing configuration seems to be the best balanced for subsonic speeds. As the speed of aircrafts increased it became clear...

Speed and altitude are two of the most important things a pilot needs to know during a flight. Failure of these instruments can lead to a "controlled flight into terrain", hypoxia from excessive altitude, a stall or a dangerous over-speed. All of these situations can...
