INTERNATIONAL SCIENCE DAY

DEPARTMENT OF PHYSICS. PRESENTS. INTERNATIONAL SCIENCE DAY.

W. orld science day highlights the significant role of science in society and the need to engage the wider public in debates on emerging scientific issues.

The year 2021 marks 2oth edition. With climate change becoming a serious threat to the lives of billions of people, this years celebration highlights the.

GUESS WHO ??.

He was an Indian physicist who carried out ground breaking work in the field of light scattering, which earned him the 1930 “ Nobel prize in physics ” In 1954, India honored him with its highest civilian award, " The Bharat R atna ”.

Its C.V Raman. Chandrasekhar Venkata Raman(1888-1970).

“ നവംബറിലെ ലാഭവും നഷ്ടവും ”. Why we say that ??. Because CV Raman born in November.

DO YOU KNOW?. Why we celebrate national science day on February 28 th.

Lets see..!. Recent achievements in Science.

Hubble Discoveries. What is astrophysics??. Astrophysics is the study of how stars, planets and other things in the Universe work, and how we can learn about them..

Hubble.

Dark matter. This is invisible but reveals its existence via gravity, makes up roughly 23 percent of the universe. By analyzing the distortions caused by dark matter's gravity on light from distant galaxies, Hubble helped construct the largest scale 3-D maps scientists have of where dark matter is distributed in the universe..

Hubble discovered two new moons of Pluto, dubbed Nix and Hydra, and recently mapped seasonal changes to its surface..

By gazing at star-forming regions such as the Orion Nebula, Hubble was able to show that proto planetary disks of gas and dust are ubiquitous around many young stars. This reinforces the idea that alien worlds are common in the universe..

Holes in galaxy. Hubble discovered that super-massive black holes probably lurk in every galaxy that has a bulge of stars at its center. The very tight link between the size of these central black holes and the size of their galaxies Hubble saw also showed that both evolve in concert, shedding light on how the universe has evolved over time..

James Webb Space Telescope. The James Webb Space Telescope (JWST) is a space telescope being jointly developed by NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). It is planned to succeed the Hubble Space Telescope as NASA's Flagship astrophysics mission. This will provide improved infrared resolution and sensitivity over Hubble, and will enable a broad range of investigations across the fields of astronomy and cosmology, including observing some of the most distant events and objects in the universe, such as the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exo - planets ..

“The JWST, is scheduled to be launched on December 18, 2021during Arianne flight VA256”.

PACE MAKER FOR BRAIN. This neuromodulator device is developed by researchers from UCSF Health This method is used to treat depression and is called deep brain stimulation It’s a cigarette box /matchbox sized device implanted in the skull It detects depression symptom and reacts by sending electric stimulations to brain to alleviate the right way.

Front view. Side view.

LET’S KNOW HOW IT WORKS. 2 electrodes are placed in brain.

Here are some funny quiz and puzzles. You have a glass of water and a glass of milk. You need to empty the two liquid into a barrel such that 1. The two liquids (water and milk) can be differentiated 2. You are able to separate milk and water. Note: Any type of divider in the box is not allowed ..

Answer is…. -> Pour the water in the barrel. -> Freeze it. -> Pour the milk in the barrel ..
