Dr.A.P.J ABDUL KALAM -A SCIENCE LEGEND AND A HERO OF INDIA


Avul Pakir Jainulabdeen Abdul Kalam ( born 15 October 1931) usually referred to as Dr. A. P. J. Abdul Kalam, is an Indian scientist and administrator who served as the 11th President of India from 2002 to 2007. Kalam was born and raised in Rameswaram, Tamil Nadu, studied physics at the St. Joseph's College, Tiruchirappalli, and aerospace engineering at the Madras Institute of Technology (MIT), Chennai.



Before his term as President, he worked as an Aerospace engineer with De-fence Research and Development Organization (DRDO) and Indian Space Research Organization (ISRO).Kalam is popularly known as the Missile Man of India for his work on the development of ballistic missile and launch vehicle technology. He played a pivotal organizational, technical and political role in India's Pokhran-II nuclear tests in 1998, the first since the original nuclear test by India in 1974. Some scientific experts have however called Kalam a man with no authority over nuclear physics but who just carried on the works of Homi J. Bhabha and Vikram Sarabhai.



CHILDHOOD -




Kalam's father was a devout Muslim, who owned boats which he rented out to local fishermen and was a good friend of Hindu religious leaders and the school teachers at Rameshwaram. APJ Abdul Kalam mentions in his biography that to support his studies, he started his career as a newspaper vendor. This was also told in the book, A Boy and His Dream: Three Stories from the Childhood of Abdul Kalam by Vinita Krishna.But he never excuse his study for his poor background.



EDUCATION -




Kalam has primary education in the Rameswaram Elementary School.At the age of 15 he joined the Schwartz High School in Ramanathapuram.Teachers at the Schwartz High School were very gentle and encouraged him to do something very special in life.Mr.Soloman would often tell to his students not to get disappointed at the failures and said we must learn a lesson from a mistakes and failure.Kalam was one of the favorite student of Mr.Soloman.Abdul Kalam completed his high school education at the Schwartz High School,and then joined St.Joseph’s College,Tiruchchirappalli,in 1950 at the age of 19.





              During his time in St.Joseph College,he shared his room with two other students from different religious backgrounds.In spite of this,these students were very cooperative and helpful to each other.Kalam lived in St.Joseph’s College for four years.While living in St.Joseph’s college,Kalam came very close to the revered Father T.N Sequeira,who used to teach English,it was due to Sequeria that Kalam began to like English literature and started reading Tolstoy,Scott,Milton,Hardy,and so on.Kalam even wrote some poems in Tamil and English.



After graduating from St.Joseph,s College,Kalam joined the Madras Institute of Technology(MIT)He managed to get his name published among the successful candidates,but admission at the MIT was not so easy.He had to have around Rs.1000 rupees for the admission fee into the college and his father was unable to find that much money.This made Kalam feel hopeless and unable to find that much money.This made Kalam feel hopeless and unable  to think which way to turn for help.But luckily his sister Zohara came to the rescue and she mortgaged her bangles and her necklaces and gave the money to Kalam.Zohara had total confidence in the success of her brother ,she would often say that one day her brother would be a great man -and she was proved right.Kalam was indebted to his sister for her timely assistance and he vowed to pay off the debt and get all the bangles and necklaces back with his own earnings one day.


CARRIER AS A AERONAUTICAL ENGINEER -



After passing out as a graduate aeronautical engineer, Kalam joined Hindustan Aeronautics Limited (HAL), Bangalore as a trainee and later joined as a technical assistant in the Directorate of Technical Development and Production of the Ministry of Defence. In the 1960's Kalam joined the Vikram Sarabhai Space Centre at Thumba in Kerala. He played a major role in the centre's evolution to a key hub of space research in India, helping to develop the country's first indigenous satellite-launch vehicle. During 1963-82, he served the ISRO in various capacities. In 1982, he rejoined DRDO as Director, and conceived the Integrated Guided Missile Development Programme (IGMDP) for five indigenous missiles. Dr. A.P.J. Abdul Kalam has established an Advanced Technology Research Centre, called 'Research Centre Imarat' to undertake development in futuristic missile technology areas. He also served as the Principal Scientific Adviser to the De-fence minister and later the Government of India. After retiring from the post Dr. Kalam joined Annamalai University till he became the President in January 2002.



THE PRESIDENT Dr.ABDUL KALAM-


Kalam served as the 11th President of India, succeeding K. R. Narayanan. He won the 2002 presidential election with an electoral vote of 922,884, surpassing 107,366 votes won by Lakshmi Sahgal. He served from 25 July 2002 to 25 July 2007.

AWARDS OF Dr. A.P.J ABDUL KALAM-




He is a member of Indian National Academy of Sciences, Astronautical Society of India and many other professional bodies. Dr. APJ abdul Kalam has been awarded Padma Bhushan in 1981, Padma Vibhushan in 1990 and India's Highest civilian Award 'The Bharat Ratna' in 1997. Other prestigious awards include Dr.Biren Roy Space Award, Om Prakash Basin Award for Science and Technology, National Nehru Award, Arya Bhatta Award etc. Dr. Kalam was conferred with the degree of Doctor of Science (D.Sc. Honoris-causa) by twenty eight universities.

NIKOLA TESLA-The father of A.C electricity

ABOUT HIM


Nikola Tesla (1856-1943) is a great science legend and one of great inventor of   human history. Due to him, we cannot imagine our life without electricity. Due to him we have electric current in our home. His visionary is the main reason, where our technology is now. His greatest achievement is Poly phase alternating system, due to which the world has its lighting capacity. July 10 is known as Tesla day in new-York and other states of   USA. At 1997, Life Magazine issued, Tesla is among 100 famous people of last 1000 years. He registered more than 700 patents worldwide. He has vision of utilization solar energy and the power of sea. He foresaw interplanetary communications and satellites.

EARLY LIFE-


 Nikola Tesla was born on July 10, 1856 in Smiljan, Lika, which was then part of  the Austo-Hungarian Empire, region of Croatia. His father, Milutin Tesla was a Serbian Orthodox Priest and his mother Djuka Mandic was an inventor in her own right of household appliances.


Tesla studied at the Realschule, Karlstadt in 1873, the Polytechnic Institute in Graz, Austria and the University of Prague. 1st He wanted to have his carrier with physics and mathematics. But after he decided to make his carrier with electrical technology. From his early youth time he was gifted with intense power of visualization and exceptional memory.

He began his career as an electrical engineer with a telephone company in Budapest in 1881.At that time he got the principle of induction motor. He designed dynamos, in Continental Edison Company in Paris. At Strassbourg in 1883, he built a prototype of the induction motor and ran it.
 LIFE AS AN INNOVATOR-

Nekola Tesla was coming America in 1884 to work for Thomas Edision. While improving Edison’s line dynamo at Edison’s lab at New Jersey, they had different point of view between Direct current and alternating current. Due to use of D.C power can transmitted to few mile. And Edison’s lamp was inefficient with direct current.

That’s why he decided to transmit power with ac for log distance.
He delivered the note of “A New System of Alternating Current Motors and Transformers” to American institute of Electrical Engineer before 1888.At that year, the partnership between Tesla and George Westinghouse was begun. Westinghouse, who was also a inventor and industrialist, was deeply influenced by Nikola’s talent. At 1891 he invented   “Tesla coil”, which is today use in Television, radio or in other electronic Equipments.

At 1895, he designed worlds 1st Hydro Electric Power Plant in Niagara Falls.In 1896 Tesla constructed an instrument to receive radio waves.  He experimented with this device and transmitted radio waves from his laboratory on South 5th Avenue. to the Gerlach Hotel at 27th Street in Manhattan.  The device had a magnet which gave off intense magnetic fields up to 20,000 lines per centimeter.




In his Colorado Springs experimental station at Colorado, he was experiment the high voltage and high frequency of electricity through Tesla Coil. He created 30 feet long spark by it.He discovered terrestrial stationary waves; through it he showed that earth can be use as a conductor. He lighted 200 lamps without wires within 40 kilometers.

With finance support of J. Pierpont Morgan, Tesla built Wardenclyffe laboratory and 1st wireless signal and power transmission tower in Shore ham.Tesla's concept of wireless electricity was used to power ocean liners, destroy warships, run industry and transportation and send communications instantaneously all over the globe.

Not only in Electrical, but also he invented lots of things in other fields. Like the fluorescent light , laser beam, wireless communications, wireless transmission of electrical energy, remote control, robotics-RAY, Tesla’s turbines and vertical takeoff aircraft are his another discoveries. Tesla invented the special vacuum tube which emitted light to be used in photography.

AWARD & OTHER ACHIEVEMENTS



IN 1915, Both Tesla and Edison were nominated as winner of Nobel Prize for physics.Neither Tesla nor Edison did not receive the award.

In 1917, Tesla was awarded the Edison Medal, the most specious electrical prize in the United States.
Nikola Tesla’s name has been honored with an International Unit of Magnetic Flux Density called “Tesla."

Tesla is known as the inventor of poly-phase alternating current.

Nikola Tesla statue is located on Goat Island to give him honor for his Niagara Falls power station.
On his 75th birthday in 1931, the inventor appeared on the cover of Time Magazine. On this occasion, Tesla received congratulatory letters from more than 70 pioneers in science and engineering including Albert Einstein. These letters were mounted and presented to Tesla in the form of a testimonial volume.  

Tesla was inducted into the Inventor’s Hall of Fame in 1975.
The Nikola Tesla Award is one of the most distinguished honors presented by the Institute of Electrical Engineers. The award has been given annually since 1976.

The Nikola Tesla Corner Sign, located at the intersection of 40th Street and 6th Avenue in Manhattan, is a memorable place of this legend.

LAST TIME


He was never marriage. His total bachelor life , he was given to science.Tesla died on January 7th, 1943 in the Hotel New Yorker, where he had lived for the last ten years of his life.  He was cremated in Ardsley on the Hudson, New York. His ashes were interned in a golden sphere, Tesla’s favorite shape, on permanent display at the Tesla Museum in Belgrade along with his death mask.
