Fermat, a lawyer by profession, was a mathematical genius. Apart from being regarded as the founder of modern number theory, he made seminal contributions to calculus and probability theory. In this article, various mathematical works of Fermat are discussed briefly along with the notoriously difficult FLT associated with him.
Emil Fischer, considered as one of the greatest chemists of all times, carried out much of the fundamental work on purines, sugars, proteins, stereochemistry and several other areas of chemistry during the late nineteenth and early twentieth century. Because most of these are biological molecules, he is known as the ‘Father of Biochemistry’. His achievements in chemical synthesis and analytical skills...
The nature of matter, or body considered in general, consists not in its being something which is hard or heavy or coloured, or which affects the senses in any way, but simply in its being something which is extended in length, breadth and depth.
Emil Fischer is considered to be the founding father of the field of peptide chemistry and originator of the term peptide. In the beginning of the 20th century, Fischer had a clear vision to foresee the day when a protein would be synthesized. Subsequent to this brilliant beginning, progress however was slow for the next 50 years. In 1953, the chemical synthesis of oxytocin by duVigneaud was a landmark...
The story of carbohydrate chemistry from its embryonic stage to the present day high profile research bridging organic chemistry and the life sciences is like a fascinating travelogue through space and time. In this brief article, this intriguing field of natural products chemistry is presented with appropriate illustrations, with the hope that it will kindle further interest in the young readers...
The author describes his ‘choice’ of a Ph.D. dissertation topic in the sixties, the interactions with his advisor, the rhythms of the mole crab and the serendipity of success in research, in a candid and humorous fashion.
Zoology, being a basic bioscience, is essential for a better understanding of applied biological disciplines. A sound background in zoology can often be the key to success in modern day cutting-edge biological research. Students of zoology have many more interesting questions to ask now than ever before. Precisely when did humans take to clothing? How is losing body hair actually correlated to body...
In this popular expository article, we discuss some important ways in which complex analysis in more than one variable is different from complex analysis in one variable. Analytic continuation in several variables is contrasted with that in one variable, and the notion of psuedoconvexity is defined. Hartogs phenomenon and the Levi problem are also discussed in an informal way.
