Thomas Edison Thomas Alva Edison  (February 11, 1847 – October 18, 1931) was an American inventor and businessman who has been described as America's greatest inventor. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures.These inventions, which include the phonograph, the motion picture camera, and the long-lasting, practical electric light bulb, have had a widespread impact on the modern industrialized world.He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest; early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He lat

Sir Isaac Newton   (25 December 1642 – 20 March 1726/27) was an English mathematician, physicist, astronomer, theologian, and author (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia  Mathematica  ( Mathematical Principles of Natural Philosophy ), first published in 1687, laid the foundations of classical mechanics. Newton also made seminal contributions to optics, and shares credit with Gottfried Wilhelm Leibniz for developing the infinitesimal calculus. In  Principia , Newton formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint until it was superseded by the theory of relativity. Newton used his mathematical description of gravity to prove Kepler's laws of planetary motion, account for tides, the trajectories of comets, the precession of t

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the idea of relativity, one in every of the 2 pillars of recent physics (alongside quantum mechanic) His work is additionally known for its influence on the philosophy of science. he's best known to the overall public for his principle formula E = mc2, which has been dubbed "the world's most famous equation". He received the 1921 honor in Physics "for his services to theoretical physics, and particularly for his discovery of the law of the photoelectric effect", a pivotal step within the development of scientific theory. The son of a salesman who later operated an electrochemical factory, Einstein was born within the German Empire but moved to Switzerland in 1895 and renounced his German citizenship in 1896. Specializing in physics and arithmetic, he received his academic teaching diploma from nation Federal Polytechnic School in Zürich in 1900.

Vikram Ambalal Sarabhai (12 August 1919 – 30 December 1971) was an Indian physicist and astronomer who initiated space research and helped develop atomic energy in India. He was honoured with Padma Bhushan in 1966 and therefore the Padma Vibhushan (posthumously) in 1972. he's internationally thought to be the daddy of the Indian program. Sarabhai started a project for the fabrication and launch of an Indian satellite. As a result, the primary Indian satellite, Aryabhatta, was put in orbit in 1975 from a Russian cosmodrome. He was the founding father of Indian Space Research Organization. The decade following independence in 1947 was a witness to a surge of innovative ideas to make a fledgling independent nation into a model democratic state committed to growth with equity within the development of its people. The establishment of Indian Institute of Management,Ahmedabad (IIMA) was the end result of 1 such innovative initiative. Vikram Sarabhai and Kasturbhai Lalbhai, bo

Avul Pakir Jainulabdeen Abdul Kalam (; 15 October 1931 – 27 July 2015) was an Indian aerospace scientist and politician who served because the 11th President of India from 2002 to 2007. He was born and raised in Ramaswaram, province and studied physics and aerospace engineering. He spent  the subsequent  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 programme and military missile development efforts. He thus came to be called the Missile Man of India for his work on the event of missile and launch vehicle technology. He also played a pivotal organisational, technical, and political role in India's Pokharan-2 nuclear tests in 1998,  the first  since the initial nuclear test by India in 1974.Kalam was elected because the 11th President of India in 2002 with the support of both the ruling Bharatiy

Stephen William Hawking was born on 8th January 1942 and died on 14th March 2018. London:The famous physics professor  Stephen William Hawking  has warned that mankind is facing the foremost dangerous time in it's history today.He said that  the earth  today is facing huge challenges like  natural process , overpopulation, epidemic diseases.'We have the technology to destroy  the planet  on which we live and haven't yet developed  the flexibleness   to escape  it.Perhaps during  some  hundred years from now,we will have built colonies amid the celebrities,but  directly ,we have  only one  planet  which  we must work together to shield it'.Hawking wrote recently within the Guardian newspaper. Hawking died at
