What Is A Half-life?

When isotopes break down, or decay, they usually split apart into two smaller atoms. Excess neutrons and protons are often sent flying off through space, taking the excess energy of the atoms with ... Continue reading

Water, Water Everywhere, But Not A Drop To Drink

That line, from The Rime of the Ancient Mariner, by Samuel Taylor Coleridge, captures a truism -- we cannot drink salt water to quench our thirst. But why not? The answer lies in understanding the ... Continue reading

Single Molecule Electroluminescence

Incandescence and luminescence are two main ways of producing light. In incandescence, electric current is passed through a conductor (filament of a light bulb for example). The resistance to the ... Continue reading

Microarrays: Chipping Away At The Mysteries Of Science And Medicine

With only a few exceptions, every cell of the body contains a full set of chromosomes and identical genes. Only a fraction of these genes are turned on, however, and it is the subset that is ... Continue reading

Vibrational Energy

VibrationalEnergyWhy is hearing such a rich and powerful sense? Maybe because it alone of all the senses has the power to fill our entire body with vibrational energy. We sometimes think of hearing as one of the 'distant' senses, distant because we can use it to perceive things from a distance without having to get too close. In some ways, though, hearing is a much 'closer' sense than even taste or touch.

All the senses gather energy, but only sound can set your body vibrating like a giant tuning fork. Sound is, in fact, vibration. When vibrations in the air beat against the thin skin of your eardrum, stretched tight like the skin of a real drum, it commences to vibrate at almost exactly the same frequency. So the first step in hearing is when your ears internalize and match the external vibrations traveling through the air, and a part of your body begins to vibrate in harmony with the soundwaves themselves.
