Understanding the meaning of ionization energy of elements
By: Norman Green
Each element, be it oxygen, lead, sodium or any other is made up of atoms. The atoms of any particular element are specific to that element. For example oxygen behaves and reacts the way it does because of the particular structure of its atoms. It...
Is time travel possible?
By: Glenn William Sherman
Time Travel: About Time! Have you ever read about an event or a time in history and thought to yourself, if only time travel were possible? Ever looked back on your own past and wished you could just go back and make amends or do...

To find out the discovery of electrons we have to travel all the way back to 1898. Back then, scientists were working with electricity, even though they did not understand that electric currents were made up of electrons. The cathode tube was a point in...

The world of physics can be strange, very strange indeed. And every once in awhile something happens during an experiment that throws a wrench into the neatly constructed model of how everything works and causes all assumptions to be reassessed. Such a thing happened to...

Something unique was spotted above the Hawaiian Islands in 1997. Powered by six propellers, it moved slowly and quietly through the sky, staying in flight above the coastal region for hours. The flying machine didn’t look like any other planes or jets. It was...
The physics of turbocharging
By: Sam Domett
The key to understanding a turbocharger is understanding volumetric efficiency. This is a measure of how effectively an engine is breathing, so force feeding it air makes it more powerful, which is what a turbocharger does. If an engine could completely fill the cylinder with...

Theory of Subjective Time Perception To understand the influence of time on the mind, we must first determine its significance. Time is measured and organized by perception - by our minds. We use the term 'time' to define the motion of events, like the events...
By: Wayne Leon Learmond
Does 'time' exist? Or is time, as we know it, man-made? Mankind, likes order, we like to know when to get up and when it is time to go to bed.. Our whole life is dominated by clocks - whether those clocks be biological, mechanical...
Understanding Electromagnetic Field (EMF) exposure
By: Alaina M. Coyle
Electromagnetic fields (EMFs) have been linked to a variety of serious diseases and illnesses – from chronic fatigue to nausea; headaches to miscarriages; brain tumors to cancer. EMFs are radiated from anything that conducts electricity, so the threat is literally all around us. How serious...

The black hole is one of the most interesting ideas in physics because the rules of the universe as we understand them react differently in black holes. Yet the traditional black hole in which gravity is so heavy that not even light can escape is...
