Louis Pasteur : Pionnier de la Microbiologie

Louis Pasteur (1822–1895) est l'un des scientifiques les plus célèbres de l'histoire de France. Chimiste et microbiologiste de formation, il a révolutionné la médecine moderne, la santé publique et l'industrie alimentaire grâce à ses découvertes majeures.

Principales Réalisations :

La théorie des germes : Il a démontré que les micro-organismes (bactéries et microbes) sont responsables des maladies et de la fermentation, réfutant ainsi définitivement la théorie de la génération spontanée.

La pasteurisation : Il a inventé ce procédé thermique qui consiste à chauffer des liquides (comme le lait et le vin) pour détruire les micro-organismes pathogènes sans altérer le produit, prolongeant ainsi leur conservation.

Les vaccins : Il a développé des vaccins salvateurs contre des maladies mortelles, notamment le charbon (pour le bétail) et, plus célèbre encore, le vaccin contre la rage en 1885.

L'Institut Pasteur : Fondé en 1887 à Paris, cet institut est devenu un centre mondialement reconnu pour la recherche biomédicale. 

Son héritage continue de sauver des millions de vies à travers le monde.

Dr Kalam

Dr APJ Abdul Kalam was born on 15th October 1931. Today is his 89th birth anniversary. He served as president of India from 2002 to 2007. He was one of India's most outstanding scientists, being trained in physics and aerospace engineering. Kalam started his career by designing a small helicopter for the Indian Army. Kalam worked in the Indian 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’s orbit in July 1980. He was also an administrator at the Defence Research and Development Organisation (DRDO). Kalam was intimately involved in India's civilian space programme and military missile development efforts. He thus came to be known as the Missile Man of India for his work on the development of ballistic missile and launch vehicle technology. Kalam was an avid author, and has written many books, such as Wings of Fire, Ignited M...

The Martians of Budapest

Isaac Asimov once said, "There is a rumor in America that there are two intelligent races on earth: Humans and Hungarians”. “The Martians of Budapest”, sometimes simply “The Martians” is a colloquial term used to describe a group of prominent Hungarian physicists and mathematicians who emigrated to the United States following the Great Purge of 1933. The term refers to — what appeared, from the perspective of Americans —to be a group of men with superhuman intellects, arriving from an obscure country and  speaking an incomprehensible foreign language.   Scientists typically thought to belong to the group include refugees from the University of Göttingen, early associates of the Institute for Advanced Study (IAS) and members of The Manhattan Project, including: John von Neumann, Paul Erdős, Eugene Wigner, Leó Szilárd, Edward Teller,  Theodore von Kármán, Paul Halmos, George Polya, John Kemeny and John Hersányi. John von Neumann (1903–1957):  The polymath genius g...

Harmanpreet Singh

Image
  Harmanpreet Singh will be remembered as one of India's greatest ever hockey players. He is now 12th on the  list of goal scorers in international hockey, with 205 goals. For India, he is 3rd, behind Dhyan Chand (570) and  Balbir Singh Sr (246). India got only 2 penalty corners throughout the Asia Cup final against China.  Harmanpreet could not convert either. But he was instrumental in setting up the winner. He executed a beautiful solo run down the left flank right upto the Chinese baseline,  and passed to Jugraj. Thus he acted as  a forward during that move, foregoing his role of deep defender. It was a moment of 'total hockey' in keeping with  'total football' popularized by Netherlands in the 1970s.
