Light - form of energy - it's nature is mystery .

Monochromatic - single frequency ; Polychromatic-many frequencies.usually prism splits up the white light into seven different colours which is known as dispersion.likewise in a waterfall the liquid drop behaves like a prism.

normally water looks colourless; but in a waterfall the sunlight travels in between air and water which partially reflects & refracts,so it looks white.

1.Solid
2.Liquid
3.Gas
4.Plasma - completely ionized gas -Superheated gaseous state
5.BEC (Bose Einstein Condensate) -Supercooled solid
Fifth state of matter . It's temperature is near absolute zero.This state of matter was first predicted by Satyendra Nath Bose and Albert Einstein in 1925.

Optical Illusion

Sun looks bigger at Sunrise & Sunset than at noon time.Why?

The intensity of Sun is lesser at Sunrise & Sunset than at noon time.So,we can see the Sun along with trees ,boat etc., But at noon time it is not possible. So Sun's size looks bigger at sunrise and sunset due to illusion.

The Cosmic Dance(r)

The Cosmic Dancer NATARAJA who performs his divine dance to destroy a weary universe and make preparations for god Brahma to start the process of creation.

The Cosmic Dance

The exploration of the subatomic world in the twentieth century has revealed the intrinsically dynamic nature of matter. It has shown that the constituents of atoms, the subatomic particles, are dynamic patterns which do not exist as isolated entities, but as integral parts of an inseparable network of interactions. These interactions involve a ceaseless flow of energy manifesting itself as the exchange of particles; a dynamic interplay in which particles are created and destroyed without end in a continual variation of energy patterns. The particle interactions give rise to the stable structures which build up the material world, which again do not remain static, but oscillate in rhythmic movements. The whole universe is thus engaged in endless motion and activity; in a continual cosmic dance of energy. This dance involves an enormous variety of patterns but, surprisingly, they fall into a few distinct categories.

Ultrasound to treat fractures

noreply@blogger.com (Thaya Ganapathy) — Wed, 21 Dec 2011 14:30:00 +0000

Doctors in the Scottish city which pioneered the use of ultrasound to scan the body are now using it to heal broken bones. Orthopedic surgeon Angus MacLean has been using the technology at Glasgow's Royal Infirmary's fracture clinic.

It has been shown to speed up recovery times for patients with severe fractures by more than a third. Ultrasound was first developed as a diagnostic tool in Glasgow in the 1950s.

"It's a very interesting scientific development and there's good evidence that it just vibrates the cells a little which then stimulates healing and regeneration in the bone."

Ultrasound waves are used at a slightly different frequency and a slightly different pulse. Research suggests this encourages cells to remove bacteria, stimulates the production of new bone cells and encourages those cells to mature more rapidly.

It is expected the cost of using ultrasound to treat fractures will reduce over time, making it a cheap way to speed up the healing of common fractures as well as complex ones.
