Introduction to Dr. A.P.J. Abdul Kalam's Career
ଡକ୍ଟର ଏ.ପି.ଜେ. ଅବଦୁଲ କଲାମଙ୍କ ବୃତ୍ତି ବିଷୟରେ ଏହି ବିଭାଗରେ ଆଲୋଚନା କରାଯାଇଛି। ସେ କିପରି ଜଣେ ମହାନ୍ ବୈଜ୍ଞାନିକ ଏବଂ ଦେଶର ରାଷ୍ଟ୍ରପତି ହେଲେ, ତାହା ଆମେ ଜାଣିବା।
Dr. A.P.J. Abdul Kalam, known as "The Missile Man of India" (ଭାରତର କ୍ଷେପଣାସ୍ତ୍ର ମାନବ), had a remarkable career contributing significantly to India's science and defense sectors. His journey from a humble background to becoming the 11th President of India is an inspiration, highlighting dedication (ନିଷ୍ଠା) and hard work.
Educational Background and Early Ambition
କଲାମଙ୍କ ଶିକ୍ଷା ଏବଂ ପ୍ରାରମ୍ଭିକ ଲକ୍ଷ୍ୟ ବିଷୟରେ ଏଠାରେ ବର୍ଣ୍ଣନା କରାଯାଇଛି। ସେ କିପରି ଉଚ୍ଚ ଶିକ୍ଷା ପାଇଁ ସଂଘର୍ଷ କରିଥିଲେ ତାହା ମଧ୍ୟ ଦର୍ଶାଯାଇଛି।
Kalam pursued his secondary education at Schwartz Higher Secondary School, where he was known as a bright and hardworking student with a strong desire to learn, especially in mathematics. He graduated in physics in 1954 from Saint Joseph’s College, Tiruchirappalli. His dream was to become a pilot. To achieve this, he applied for engineering at the Madras Institute of Technology. The course fee, around a thousand rupees, was a significant challenge. His elder sister, Asim Zohra, compassionately (ଦୟାଳୁ ଭାବରେ) mortgaged (ବନ୍ଧକ ରଖିଲେ) her gold ornaments to help him pay for his admission. He successfully completed his aerospace engineering in 1960.
Career in Aerospace and Defense
ଏହି ବିଭାଗରେ କଲାମଙ୍କ ମହାକାଶ ଏବଂ ପ୍ରତିରକ୍ଷା କ୍ଷେତ୍ରରେ କାର୍ଯ୍ୟ ବିଷୟରେ କୁହାଯାଇଛି। ସେ କିପରି ଭାରତର ପ୍ରଥମ ଉପଗ୍ରହ ଉତକ୍ଷେପଣ ଯାନରେ କାର୍ଯ୍ୟ କରିଥିଲେ ତାହା ଜାଣିବା।
Kalam began his career as a trainee at Hindustan Aeronautics Limited (HAL) in Bangalore. He then joined the Defence Research Development Organisation (DRDO) as a scientist. In 1969, he transferred to the Indian Space Research Organisation (ISRO), where he served as the Project Director of India’s first Satellite Launch Vehicle (SLV-III). The SLV's purpose was to develop technology to launch satellites (ଉପଗ୍ରହ). Under Dr. Kalam’s direct guidance (ମାର୍ଗଦର୍ଶନ) and supervision (ତତ୍ତ୍ୱାବଧାନ), the first Rohini satellite was successfully launched into orbit in 1980.
Integrated Missile Development Programme (IGMDP)
ISRO ରେ 19 ବର୍ଷ କାମ କରିବା ପରେ, କଲାମ DRDO କୁ ଫେରିଲେ। ସେଠାରେ ସେ ଭାରତର କ୍ଷେପଣାସ୍ତ୍ର ବିକାଶ କାର୍ଯ୍ୟକ୍ରମର ନେତୃତ୍ୱ ନେଇଥିଲେ।
After nineteen fruitful years in ISRO, Kalam returned to DRDO to head the country’s Integrated Missile Development Programme (IGMDP). He played a leading role in the development of India’s missiles (କ୍ଷେପଣାସ୍ତ୍ର) and nuclear weapons programme. This programme was highly successful, leading to the development of four significant missiles:
- Prithvi
- Trishul
- Akash
- Nag
The success of this programme earned him the popular title "The Missile Man of India."
Nuclear Tests and National Service
1998 ରେ, କଲାମ ପୋଖରାନ-II ପରମାଣୁ ପରୀକ୍ଷଣର ତତ୍ତ୍ୱାବଧାନ କରିଥିଲେ। ଏହା ଭାରତ ପାଇଁ ଏକ ଗୁରୁତ୍ୱପୂର୍ଣ୍ଣ ମୁହୂର୍ତ୍ତ ଥିଲା।
As the chief of DRDO in 1998, Dr. Kalam supervised the Pokhran-II nuclear tests, camping in Rajasthan’s Thar Desert for over a fortnight. He described this successful test as a "defining moment" (ନିର୍ଣ୍ଣାୟକ ମୁହୂର୍ତ୍ତ) in India's history. From July 1992 to December 1999, he also served as the Chief Scientific Adviser to the Prime Minister and the Secretary of Defence Research and Development Organisation.
Awards and Recognition
କଲାମଙ୍କୁ ତାଙ୍କର ମହାନ ଅବଦାନ ପାଇଁ ଅନେକ ପୁରସ୍କାର ମିଳିଥିଲା। ଭାରତ ରତ୍ନ ହେଉଛି ଆମ ଦେଶର ସର୍ବୋଚ୍ଚ ନାଗରିକ ସମ୍ମାନ।
For his immense contributions (ଅବଦାନ) to space, defense, and nuclear technology, Dr. Kalam received several prestigious (ପ୍ରତିଷ୍ଠିତ) awards:
- Padma Bhushan: 1981
- Padma Vibhushan: 1990
- Bharat Ratna: 1997 (India's highest civilian honour)

ବିଜ୍ଞାନ ଏବଂ ପ୍ରତିରକ୍ଷା କ୍ଷେତ୍ରରେ କଲାମଙ୍କ ବୃତ୍ତିଗତ ଯାତ୍ରାକୁ ଏକ ସରଳ ଫ୍ଲୋଚାର୍ଟ ମାଧ୍ୟମରେ ଦେଖାଯାଇଛି।
Illustrative Example: Scientific Calculation (Syntax Demonstration)
ବିଜ୍ଞାନରେ ଗାଣିତିକ ସୂତ୍ର କିପରି ବ୍ୟବହାର କରାଯାଏ ତାହା ଦେଖାଇବା ପାଇଁ ଏକ ସରଳ ଉଦାହରଣ। ଏହି ପାଠ୍ୟକ୍ରମରେ ସିଧାସଳଖ ଗଣିତ ନାହିଁ, କିନ୍ତୁ ବୈଜ୍ଞାନିକମାନେ ଏହାକୁ ବ୍ୟବହାର କରନ୍ତି।
In science and engineering, especially in missile technology, calculations are crucial. For instance, the force () required to accelerate a missile of mass () with an acceleration () is given by Newton's second law:
If a missile has a mass of and needs an acceleration of , the force required would be:
This simple example shows how mathematical formulas are applied in scientific fields like defense technology.
