His birthdate is sometimes also marked as December 25, 1642, due to England's use of the Julian calendar at the time. This celebrated English physicist and mathematician, known for his work on gravity and laws of motion, is a key figure in the Scientific Revolution. Today on the Google home page, an animated apple is falling, over and over, with a satisfying plunk—a 367th birthday tribute to Sir Isaac Newton. Legend has it that Isaac Newton formulated gravitational theory in 1665 or 1666 after watching an apple fall and asking why the apple fell straight down, rather than sideways or even upward. "He showed that the force that makes the apple fall and that holds us on the ground is the same as the force that keeps the moon and planets in their orbits," said Martin Rees, President of Britain's Royal Society, the United Kin...

Bioinformatics Discipline

Image
Bioinformatics derives knowledge from computer analysis of biological data. These can consist of the information stored in the genetic code, but also experimental results from various sources, patient statistics, and scientific literature. Research in bioinformatics includes method development for storage, retrieval, and analysis of the data. Bioinformatics is a rapidly developing branch of biology and is highly interdisciplinary, using techniques and concepts from informatics, statistics, mathematics, chemistry, biochemistry, physics, and linguistics. It has many practical applications in different areas of biology and medicine. Roughly, bioinformatics describes any use of computers to handle biological information. In practice the definition used by most people is narrower; bioinformatics to them is a synonym for "computational molecular biology" – the use of computers to characterize the molecular components of living things. Simple definition for Bioinformatics:- “ T...
