Roots of Indian Science

The foundation of science in ancient India was laid by writings in Vedas which provided impetus for development of modern science globally in the twentieth century. The interest in Vedas and the Vedic texts got revived due to their study by eminent western scholars in the 19th century. The scientific ideas expounded in Vedic literature led to some epoch making ideas/discoveries that have truly revolutionized science, particularly physics and medicine. These posters present an overview of the work done by some of the ancient Indian seers and scholars who wrote commentaries on Vedas and other Vedic texts.

Inventions and Inventors

The histories of development of science in the world from Vedic times to the present, with special reference to India, are pictorially depicted through these posters. Students visiting the museum are encouraged to view these exhibits. Replicas of some of the original instruments are also kept for demonstration as well as hands-on experimentation by students.

Example: A replica of ”Maglev train‘ is exhibited to understand the phenomenon of magnetic levitation.

Display of scientific instruments

Fundamental principles of science are demonstrated through models of reasonably large size. Students are encouraged to perform experiments with these instruments. Some of the instruments which formed the basis of Nobel prize awards to the concerned scientists, such as Michelson interferometer, Millikan oil drop experiment, Zeeman Effect, Frank Hertz experiment, Einstein’s photo electric effect etc., are also displayed with appropriate modifications in the original instruments employing state of the art digital technology.

Digital spectrometer, digital travelling microscope, binocular, digital vernier, digital screw gauge etc. are displayed so that interested teachers/ students can easily learn to use them. Appropriate write-ups are provided along with the instruments for ready reference.

Research and developments in Lecture Demonstration Instruments

Science is a practical subject, best understood through experimentation. We, therefore, need to have skilled teachers so that they can perform various experiments by themselves and also guide their students to do hands on experiments using various instruments.

. The conventional ”chalk and talk” method of teaching being followed in our class rooms is inadequate to teach basic science subjects. Interactive lecture demonstration (ILD), a new method of teaching science, is being followed in some of the western countries. To adopt ILD, we need to upgrade our instruments first. Most of the instruments used in our laboratories based on the analog technology have now become obsolete. Our Foundation has initiated a programme of design and development of lecture demonstration instruments for high schools. Using the latest digital microcontroller technology, these instruments will be designed and developed in-house in this center as part of our R&D program.

A laser based optical kit for demonstrating the phenomena of convergence, divergence, total internal reflection, laws of reflection of light, and defects of human vision, has been designed by D R Baluragi and is available in the museum for the purpose of lecture demonstration. Many more of such instruments are in the process of designing/fabrication and will be displayed in the museum in due course.
