The Melting Point

Physical properties of a material fall into two categories: intrinsic properties determined by the structure of the particular molecule, and bulk properties characteristic of quantities of molecules together as bulk solids, liquids, or gases. The melting point of a pure substance is a bulk property and represents the point of transition of physical ...

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.
