Life History of Dr. A.P.J. Abdul Kalam

Avul Pakir Jainulabdeen Abdul Kalam usually known Dr. A. P. J. Abdul Kalam, was the 11th President of India, serving from 2002 to 2007, he is one of the few presidents who have touched the hearts thats why during his term as President, he was popularly known as the People’s President. In India he is highly respected as a scientist and as an engineer. He is popularly known as the Missile Man of India for his work on development of ballistic missile and space rocket technology.

Stories of extreme hardship, braving impossible odds and innumerable sacrifices, abound in the lives of nearly 90 percent of the students in the country. But among them, some perform exceptionally well. Their academic laurels are so brilliant, that at times their CV looks intimidating. And each one acknowledges that it’s the right education that made them what they are today.
In special session at the IIT Delhi campus, he shares his views on the topic “How India can innovate better?”, watch great Interacts with Dr. APJ Abdul Kalam.
Several months back, after finishing an interview with Dr APJ Kalam, and just before leaving his Rajaji Marg residence he made me repeat these three words in a schoolteacher’s tone: perseverance, hard work and patience.
This, he said, was alone the path to progress. Later, much later, I realised, that those were the very words he’s lived by all through his life. They are both philosophical and practical, quite like the world he grew up in as a boy in the island town of Rameswaran, in south India.
Kalam was born on 15 October 1931 to a Tamil Muslim family in Rameswaram in the Indian state of Tamil Nadu. His father, a humble boat owner, Jainulabdeen, was a devout Muslim and a close friend of the Rameswaran temple priest. Kalam was brought up in a multi-religious, tolerant society; one with a progressive outlook. His father often quoted from the Quran to make the young Kalam see the world without fear. He had seven siblings, and a doting mother who, at times, made chappatis for Kalam, while the others were given rice as Kalam’s day would start at four in the morning and end at 11 pm.

His father wasn’t educated, but he wanted Kalam to study. Kalam would get up at 4 am, bathe, and then go for his mathematics class, which was taught by a teacher who took only five students in the whole session; and bathing before class was a condition he had laid to all his students. After his morning class, Kalam along with his cousin Samsuddin went around town distributing the newspaper. As the town had no electricity, kerosene lamps were lit at his home between 7 pm and 9 pm. But because Kalam studied until 11, his mother would save some for him for later use.
Being a bright student, Kalam always had the support of his schoolteachers. Schwarzt High School’s Iyadurai Solomon often told Kalam that if he truly, intensely desired something, he would get it. “This made me fearless,” said Dr Kalam. And outside school, Ahmed Jallaluddin, who later became his brother-in-law, and Samsuddin, encouraged Kalam to appreciate nature’s wonders. So at once, while growing up, he was exposed to a religious and a practical way of looking at the world.
The flight of birds had fascinated him since he was a boy, but it was years later he realised that he wanted to fly aircrafts. After finishing school, he took up Physics at St Joseph’s College, Trichi, but towards the end he was dissatisfied. When he discovered aeronautical engineering, he regretted having lost three precious years. But he was glad to have discovered Leo Tolstoy, Thomas Hardy and F Scott Fitzgerald and other English poets in his college years.
At Madras Institute of Technology (MIT), Chennai, where Kalam studied aeronautics, he learnt an important lesson: the value of time. He was leading a project on system design, when one day the principal walked into the class to see his work. He appeared dissatisfied and told Kalam that he wanted the project finished in the next two days; else his scholarship aid would be withdrawn. That unsettled Kalam; years of his father’s hardships would come to naught. Kalam worked without food and sleep. On the last day, his professor came to check on his progress. He was impressed and said: “I was putting you under stress and asking you to meet a difficult deadline,” recounted Dr Kalam.
Although Kalam has led several projects in his professional life, he’s treated each like his last. Such was his passion. No wonder, he’s always led projects. His advisor, Major General R Swaminathan explained Kalam’s success as a leader. “He has this unique capability of being a boss as well as a worker. He can take on any role with ease.”
When Dr Kalam’s first major project SLV 3-failed the first time he was almost shattered. Also, around this time, Kalam’s childhood mentor, Jallaluddin, died. “A part of me too passed away…” said Dr Kalam. But he never thought of quitting after SLV-3. “I knew that for success, we have to work hard and persevere.” And so, SLV-3 was launched again, this time with success. He drew strength from philosophy, religion and literature to tide by his professional setbacks; also a life with few companions. In time, he also learnt to deal with professional jealousy and uncooperative team members.
Kalam played a pivotal organisational, technical and political role in India’s Pokhran-II nuclear test in 1998, the first since the original nuclear test by India in 1974. He is chancellor of Indian Institute of Space Science and Technology (Thiruvanthapuram), a professor at Anna University (Chennai) and adjunct/visiting faculty at many other academic and research institutions across India.
Success followed Dr Kalam. Prithvi, Agni, Akash, Trishul and Nag missiles were huge successes. He was awarded the Padma Bhushan and Bharat Ratna, and then he became the President of India; one of the few presidents who have touched the hearts of so many poor children in the country. Because he also came from a poor background, he knew the power of education in changing one’s future.
On the evening of 27 July 2015, Kalam collapsed at around 6:30 p.m. while delivering a lecture on “The Livable Planet Earth” at the Indian Institute of Management Shillong. He was rushed to Bethania Hospital in a critical condition and was placed in the intensive care unit, but was confirmed dead of a massivecardiac arrest.

Four legged SNAKE



Snakes’ earliest ancestors liked to hug it out.
Scientists announced this week the discovery of a 113-million-year-old four-legged reptile fossil found in Brazil. That makes it the most primitive ancestor of modern-day snakes ever found. While scientists have previously identified ancient snake fossils rocking a pair of hind limbs, this is also the first four-legged snake scientists have ever seen.
And the way this snake used its delicate arms helps clarify a longstanding debate about the snake family tree.

All Arms and Legs

The newly identified reptile, dubbed Tetrapodophis amplectus, is tiny. It measures just over 7 inches from snout to tail tip, and its arms and legs are just 4 and 7 milimeters long, respectively. But despite their small size, the snake’s limbs were quite well developed: It had long fingers and toes with claws at the ends.

Scientists don’t think Tetrapodophis used its limbs for movement, as it likely slithered from place to place like modern snakes. Instead, the lanky reptile used its limbs to grasp prey while it coiled around their bodies. The limbs were also handy for hugging another snake during a mating session.
Given these observations, the name Tetrapodophis amplectus makes perfect sense. Tetrapodophis, the fossil’s new genus, means “four-footed snake;” andamplectus is Latin for “embrace.” Scientists published their description of the species this week in the journal Science.

Settling the Score

Scientists have long debated whether snakes’ ancient ancestors were marine reptiles that eventually slithered onto dry land, or if they were landlubbers from the start. The discovery of Tetrapodophis certainly tilts the scales in favor of the latter scenario.

By all appearances, Tetrapodophis lived on dry land and not in water.Tetrapodophis doesn’t sport a paddle-shaped tail, and it bears no signs of fins used for swimming. Instead, its short snout and long body indicate it was well adapted to a burrowing lifestyle – its limbs may have helped with the task of digging.
Based on a genetic analysis of modern and ancient snakes, as well as other related reptiles, scientists positioned Tetrapodophis as the earliest ancestor of snakes we know today, further proof that snake ancestors stuck to dry land.
Research suggests that snakes lost their legs by growing them more slowly and over a shorter period of time until they disappeared altogether. Ancient snakes’ arms, perhaps, disrupted movements like burrowing, which made their limbs useless, paving the way for the streamlined snake species we know today
