Explore the world of physics, motion, and energy with Dr. Shini Somara.

Let's talk about astrophysics, cosmology and how our universe works.
Getting power at home is pretty amazing – and much more complicated than it may seem.
We've learned about light and how to bend it to our will. But what can we LEARN from it?
