An overview on backscatter x-ray technology
By: Russell Waldron
The introduction of Backscatter X-ray Machines has certainly caused a load of controversy world-wide. These were specifically designed with airport security in mind. Unfortunately in this day and age with terrorist attacks at the forefront of international security focus, many feel there is definitely a...

Backscatter x-ray technology is extensively used for airport security purposes. Originally introduced by Dr. Steven W. Smith in 1992 mostly as commercial devices, backscatter scanners detect radiation that bounces off the surface of the body and create its image with the x-rays. Advanced imaging technology...

How Does the Theory of Relativity Apply to Plane Travel? In his General Theory of Relativity, Einstein treats space and time as one four-dimensional object. He called this space time. In his theory he states that time is not absolute and flows differently for different...
Could time travel be possible in the future
By: T.S. Garp
Time Machine Possibly the ultimate journey of all time would be not to travel to the stars or to another planet or even under the great depths of the ocean but rather through time itself. Time travelers could explore all of history, past, present, and...
Is time travel possible?
By: T.S. Garp
Time Travel or the Rip Van Winkle Complex Where did the idea of time travel originate from? What were some of the earliest time travel tales ever told? What are the consequences of traveling into the far future? With new advancements in technology happening every...

Backscatter x-ray technology is an imaging process, using the radiation that reflects back from the target, or, in the case of airport screening, the person. This, and the millimeter wave scanner are used as security scanning measures at airports in the United States and several...
Wormholes and FTL travel: Is science fiction and science edging closer together?
By: T.S. Garp
Time Travelers Scientists believe that traveling through time is theoretically possible under the right conditions. In physics and in science fiction, a method of time travel is often speculative at best. But what if time travelers actually existed? How would we perceive them? And what...
Isaac Newton's Three Laws of Motion
By: K.P. Arnolds
Isaac Newton was one of the most famous physicist that ever lived. Even though he was very educated in many subjects including math, astronomy, alchemy, and theology, he is most famous for his contributions to physics. His most famous was Newton's Laws of Motion...

The science of quantum theory is a socially constructed account of the universe, and just one of many possible accounts. In fact, all knowledge of the universe is socially constructed and complimentary, allowing physicists to connect observations in the everyday world of the laboratory with...
