STREAM-2020

STREAM: Second Edition

The Physics Society of IISER Berhampur celebrated the second edition of Science Open Day by organizing several live demonstrations themed on "LIGHT". The concise yet exciting demonstrations were followed by interaction with the groups of our young visitors.

We express our gratitude to the Astronomy Club, NAXATRA for their collaboration with us throughout the course of the event.

Missed the event?

No worries!

Here we give an outlook of what had happened at 137 Inverse on the 1st of February, 2020.

The Sun

Made in collaboration with NAXATRA, this well built model was used to explain the different layers of the Sun and a brief note of their thermal properties. Furthermore, the surface features were explained along-with the most detailed picture of the Sun's surface taken, which was in the news those days.

Robomouse - Maze Solving Robot

With the emergence of Artificial Intelligence and Machine Learning , self driving cars and automated Machines are now part of our realty. This robot was designed using Arduino micro-controller . It imitate the behavior of modern self driven car by trying to solve maze and find the exit route of its own.

LiFi - Laser Communication

Historically , communication has been a crucial aspect of the human civilization. The presentation included explanations on how to encode information using the Morse code and transfer it using lasers and photo-detectors .

How we discover other Earths?

Simple ways like Transit method and measuring Radial velocity have been in use since the past century to detect exoplanets. Demonstrating the transit method using a simple model, we compared our observations and also displayed simulations of how the brightness curve would change with size and number of planets in orbit.

The ‘spark’ side of fire

Of the numerous mind-boggling aspects of "Flame" or "Fire", one to look upon with curiosity is its ability to cause electrical breakdown of its surrounding medium. This experiment demonstrated that a certain region of flame can ionize the molecules of the medium, causing sparks to occur when two electrodes are brought closer (but not as close as in absence of flame).

3D Model of Syzygy

A Syzygy is a roughly straight-line configuration of three or more celestial bodies in a gravitational system. Here, we explained the most common one, i.e. solar eclipse and its different features. A VR kit was also arranged to get a better knowledge of the topic.

Interference of Light

A simple but elegant setup was used to demonstrate the popular phenomenon of interference of light waves as they encounter slits of the order of wavelength of light. The similarities and differences in the interference patterns of single and double slits were demonstrated.

The LIGO Experiment

Drawing inspiration from the fundamentals of interference, a MIchelson interferometer was used to demonstrate how gravitational waves can be detected. A beautiful depiction of the gravitational waves was given by rolling marbles of different masses on a trampoline, which represented a 2-D analogue of space-time fabric.
