Science

Science, as a body of knowledge as we know it today, is remarkably young, not more than a few hundred years old. And what we know also as science largely relates to the facts and explanations of everyday life. There is a need to examine what constitutes science as a process, the discipline of doing science. What are those elements of study and practice that distinguish science as an endeavour? What are the social dynamics that influence the practice of science? What are the limits of science itself? These are questions that have to be considered by a student of science. Science is also often understood as learning science as a subject and this involves the teaching and learning science and the pedagogy that must be adopted to develop a scientific bent of mind and to prepare the learner for doing science. This is a portal for students and teachers to understand and share resources on both these areas.

Famous Scientists

Francis Crick and Thomas Watson - physicist and ornithologist - made one of the most important discoveries of molecular biology in the last century. They discovered the structure of the deoxyribonucleic acid (DNA) the repository of genetic material.

While the structure of the constituents itself was known, it took several scientists to discover the framework. While Watson and Crick were awarded the Nobel Prize for proposing the double helix model of the DNA - described by molecular biologists as sublimely beautiful, another biophysicist Rosalind Franklin made several crucial discoveries of the DNA including one of the forms of the double helix. Her X-ray crystallography images provided the crucial links and inputs for formulation of a helical model. Rosalind Franklin died before the announcement of the Nobel Prize and her contribution to the discovery of the DNA remained known only to molecular biologists and geneticists.
