While the world awaited the first colour TV in 1928, CV Raman, an Indian scientist made a stunning discovery
India has come a long way since Independence in the development of science and technology. February 28 is celebrated as the National Science Day in India. Indian
Space Research Agency prepares for Chandrayaan-2, the country's second
mission to the Moon. The indigenous mission comprises of an Orbiter,
Lander and Rover. The mission will carry a six-wheeled Rover which will
move around the landing site in the semi-autonomous mode as decided by
the ground commands. The instruments on the rover will observe the lunar
surface and send back data, which will be useful for analysis of the
lunar soil. The Chandrayaan-2 would orbit around the moon and perform
the objectives of remote sensing the moon.
What makes the mission interesting is that the
nearly Rs 800 crore project is cheaper than the production budget of the
Hollywood movie 'Interstellar'. Speaking about the mission, K Sivan,
ISRO chairman, in an exclusive interview with TOI explained the
procedures involved in keeping costs to a minimum. By miniaturising the
complex, big system with strict quality control and maximising the
output or the product, the space mission was kept cost-effective and
frugal, the Chairman said.
India has come a long way since Independence in the development of science and technology. February 28 is National Science Day in India. The event has been celebrated every year since 1987 to mark the contributions of scientist Chandrasekhara Venkata Raman to the field of science. It was on this day (28 February) in 1928 that he discovered a phenomenon of scattering of photons which was later known as the Raman Effect. For his discovery, Raman was awarded the Nobel Prize in 1930, making it the first Nobel Prize for India in the field of Science.
What is the Raman Effect?
The Raman Effect was a phenomenon
first observed by the physicist CV Raman while working in the lab of
the Indian Association for the Cultivation of Science, Kolkata. The
phenomenon occurs when there is a change in the wavelength of light when
a light beam is deflected by molecules. For example, when a beam of
light traverses a dust-free, transparent material, a small fraction of
the light emerges in directions apart from the incoming beam. While most
of this scattered light is of the same wavelength, some part of it has
wavelengths which are different from the incident light. This is known
as the Raman Effect.
The current theme for 2018 is 'Science and Technology for Sustainable Future'. Considering
that India imports 80 per cent of its oil needs, the fall in crude oil
prices in 2014 was regarded as a sign that the country would meet its
fiscal deficit targets. While considering crude price movements, the
Draft National Energy Policy (DNEP) has acknowledged the need to
strengthen renewables, according to an Economic Times report.
On the occasion of National Science Day, National
Awards will be conferred on the awardees for 2017 for their contribution
in the communication of Science and Technology and promote scientific
temper.
Why this day is observed as National Science Day
28 February is celebrated in India every year as
National Science Day to spread the message of the importance of
scientific applications in the day-to-day life of the people. To explore
new horizons and push scientific frontiers further, we need to
encourage the nation's youth to develop a passion for science. The
government has this noble aim as it, through the Department of Science
and Technology, organises events such as Science Week which culminates
in National Science Day.
The event displays the achievements in the field of
science for the betterment of humanity. The day also is used to discuss
issues and implementation of newer technologies for the development of
science. (Via timesnow)
