IF YOU WISH TO TRAVEL FAR

AND FAST,TRAVEL LIGHT ---

Cesare Pavese

On 20th December 2013, in its 68th Session, UN General Assembly proclaimed 2015 as the International Year of Light and Light-based Technologies..

International Year of Light

” The International Year of Light is “a global initiative adopted by the United Nations to raise awareness of how optical technologies promote sustainable development and provide solutions to worldwide challenges in energy, education, agriculture, communications and health.

Electromagnetic Spectrum

The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. It extends from High frequency Radio waves to Low frequency Gamma radiations, thereby covering wavelengths from thousands of kilometers down to a fraction of the size of an atom. The limit for long wavelengths is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length.

Different Parts of Electromagnetic Spectrum

Radio: Your radio captures radio waves emitted by radio stations, bringing your favorite tunes. Radio waves are also emitted by stars and gases in space.

Microwave: Microwave radiation will cook your popcorn in just a few minutes, but is also used by astronomers to learn about the structure of nearby galaxies.

Infrared: Night vision goggles pick up the infrared light emitted by our skin and objects with heat. In space, infrared light helps us map the dust between stars.

Visible: Our eyes detect visible light. Fireflies, light bulbs, and stars all emit visible light.

Ultraviolet: Ultraviolet radiation is emitted by the Sun and are the reason skin tans and burns. "Hot" objects in space emit UV radiation as well.

X-ray: A dentist uses X-rays to image your teeth, and airport security uses them to see through your bag. Hot gases in the Universe also emit X-rays.

Gamma ray: Doctors use gamma-ray imaging to see inside your body. The biggest gamma-ray generator of all is the Universe.

AvulPakirJainulabdeen "A. P. J." Abdul Kalam was the 11th President of India . A career scientist turned politician, Kalam was born and raised in Rameswaram, Tamil Nadu, and studied physics and aerospace engineering. He spent four decades as a scientist and science administrator, mainly at the Defence Research and Development Organisation (DRDO) and Indian Space Research Organisation (ISRO) and was intimately involved in India's civilian space program and military missile development efforts. He thus came to be known as the Missile Man of India

His Contribution

Ÿ Kalam started his career by designing a small helicopter for the Indian Army, but remained unconvinced with the choice of his job at DRDO.

Ÿ Kalam was also part of the INCOSPAR committee working under Vikram Sarabhai, the renowned space scientist.[9] In 1969, Kalam was transferred to theIndian Space Research Organization (ISRO) where he was the project director of India's first indigenous Satellite Launch Vehicle (SLV-III) which successfully deployed the Rohini satellite in near earth orbit in July 1980 and started to work on SLV project.

Ÿ Kalam first started work on an expandable rocket project independently at DRDO in 1965. In 1969, Kalam received the government's approval and expanded the program to include more engineers.

Ÿ During the period between the 1970s and 1990s, Kalam made an effort to develop the Polar SLV and SLV-III projects, both of which proved to be success.

Ÿ In the 1970s, Kalam also directed two projects, namely, Project Devil and Project Valiant , which sought to develop ballistic missiles from the technology of the successful SLV programme.

Ÿ His research and educational leadership brought him great laurels and prestige in 1980s, which prompted the government to initiate an advanced missile program under his directorship.

Ÿ Kalam and Dr. V. S. Arunachalam, metallurgist and scientific adviser to the Defense Minister, worked and were instrumental in getting the cabinet approval for allocating 388 crore rupees for the mission, named Integrated Guided Missile Development Program (I.G.M.D.P) and appointed Kalam as the Chief Executive.

Ÿ Kalam played a major part in developing many missiles under the mission including Agni, an intermediate range ballistic missile and Prithvi, the tactical surface-to-surface missile. He was the Chief Scientific Adviser to the Prime Minister and the Secretary of Defence Research and Development Organisation from July 1992 to December 1999.

Ÿ The Pokhran-II nuclear tests were conducted during this period where he played an intensive political and technological role. In 1998, along with cardiologist Dr.Soma Raju, Kalam developed a low cost Coronary stent. It was named as "Kalam-Raju Stent" honouring them.

Ÿ In 2012, the duo, designed a rugged tablet PC for health care in rural areas, which was named as "Kalam-Raju Tablet".

Lets read some stories

Eureka Eureka

Archimedes was a Greek scientist.The King of the land Syracuse wanted to wear a Golden Crown. He gave some gold to a goldsmith to make a suitable crown. After few days, the goldsmith brought the finished crown to the King. The crown was weighed. The weight of the crown was equal to the gold given to the goldsmith by the King. The King looked at the color of the crown. He had a suspicion. The goldsmith could have stolen some gold from the gold given to him. The King wanted to find out the truth. He asked his court scientist Archimedes to find out. The King said, “Find out how much gold had been stolen?”

Archimedes thought about the problem day and night. One day he was about to have his bath, but he was busy thinking. He did not notice the bathtub. The water in the bathtub was already full to the brim. He slid into the bathtub. Immediately a large quantity of water flowed over the brim of the bath tub. He noticed this suddenly. His brain wave worked suddenly. He jumped out of the bathtub, shouting, “Eureka! Eureka!” Eureka in Greek means “I have found it.”

Different metals of the same weight have different volumes. Objects, put in water, will displace water. The displaced water will be equal to their volume.

Archimedes took two bowls. He filled them with water to the brim. Then he placed each bowl separately

in the middle of the large vessels. He placed the crown in one bowl. Water overflowed. It collected at the

bottom of the outer vessel. Then he took a cube of pure gold. This cube of gold was equal in weight to the crown. He kept this gold cube in the middle of the second bowl. Here also water overflowed. Water got collected at the bottom of the outer bowl.

Archimedes then measured the quantity of water in the two vessels. He found out the difference in the water overflow. The crown had sent out more water. The cube of gold had sent out less water. But both the crown and the gold cube were of the same weight. So, they should have sent out the same quantity of water. Therefore, the crown had some other metals mixed in it. These metals took up more space in the

Hero Mother

One day Thomas Edison came home and gave a paper to his mother. He told her, “ My teacher gave this paper to me, and told me to only give it to my mother. His mother's eyes were tearful as she read out the letter aloud to her son: Your child is a genius. This school is too small for him and doesn't have enough good teachers for training him. Please teach him yourself.

Many years after Edison's mother dies and he was one of the greatest inventors of the century. One day he was looking through the old family things. Suddenly he saw folded paper in the corner of the drawer in a desk. He took it and opened it up. On the paper it was written: Your son is addled (Mentally ill). We won't let him come to school any more.

Edison cried for hours and the wrote in his diary: “Thomas Alva Edison was an addled child that, by the hero mother, became the genius of the century”.
