9000 Years Prehistoric Dental Drill

Researchers say prehistoric man invented dental drill 9,000 years ago. Below is an experimental reconstruction photos of a probable method for producing the drilled molar crowns found at a 7000-9000 BP Neolithic graveyard in Mehrgarh, Pakistan.(AP Photo/Luca Bondioli, Pigorini Museum, Rome)

Inside Our Body

This image of red blood cells is one of a series appearing in the book Inside The Body: Fantastic Images from Beneath the Skin.

Here the blood cells are travelling along a vein within the liver. The images are provided by the Science Photo Library.
This bead-like structure with its projecting legs is a nerve cell. It sends signals and commands to and from the brain.

This dirty-looking surface is actually a healthy tooth. The cells in the green layer produce enamel, which protects the tooth.

A cross section of a piece of carpet? This is actually the small intestine where food is digested.

The surface of the tongue is rough due to these paillae, which contain the taste buds and send tactile information to the brain.
The cells lining the stomach secrete a layer of mucus to protect against the acidic gastric juices.

These crystals may look pretty, but the kidney stones they form can be extremely painful to pass through the urine.

These match-like structures are found in the brain and secrete a substance that cushions the brain and spinal cord against shock.
Rose petals scattered on a scarlet divan? This is actually the lining of the rectum.

Laser Show in Hong Kong

The oriental is now the face of modernity. It boasts of a rich past and reflects everything that’s new. With cultural integrity, they boast of technological advancement. Together it’s a combination that has made the world take notice of Hong Kong. If you were watching a Laser Show in Hong Kong, you’d never know where you were, because they give you the best there is to offer.

Light Amplification by Stimulated Emission of Radiation is better known as LASER. In such shows an optical source emits photons in a consistent beam. This near-monochromatic single wavelength works upon application of quantum mechanics and thermodynamics theory. This show use The StratoSphere. It is a unique high quality inflatable venue with the ability to show high definition video and laser imagery on the surface of the sphere. The StratoSpheres range in size from 30-70ft in diameter. This is the technicality of it.

The beauty of it is much more comprehensive. Such an extravagant play of light is not only a memory you’ll never forget but it helps you transcend to another unknown zone till as long as it lasts. A Laser Show in Hong Kong could take you around the world and show you what the place is about, all in the span of a great show.


A LASER (Light Amplification by Stimulated Emission of Radiation) is an optical source that emits photons in a coherent beam. Laser light is typically near-monochromatic, i.e. consisting of a single wavelength or hue, and emitted in a narrow beam. This is in contrast to common light sources, such as the incandescent light bulb, which emit incoherent photons in almost all directions, usually over a wide spectrum of wavelengths. Laser action is understood by application of quantum mechanics and thermodynamics theory (see laser science).

The verb "to lase" means "to produce coherent light" or possibly "to cut or otherwise treat with coherent light", and is a back-formation of the term laser. [wikipedia]
