Let's talk about astrophysics, cosmology and how our universe works.
10:19
Let's talk Einstein and Nuclear Physics. What does E=MC2 actually mean? Why is it useful?
9:02
Why is e=mc2 such a big deal? And what about this grumpy cat in a box and probability?

We've all heard of relativity, but what is it? How does it relate to light and motion?
9:56
Shini talks to us about optical instruments and how they make magnification possible.
8:21
We've learned about light and how to bend it to our will. But what can we LEARN from it?
9:41
Light's behavior seems counterintuitive. That is, until you figure out light is a wave.
9:26
Sunlight, moonlight, torchlight... They all work the same. Let's talk about light!
Maxwell's Equations tell us a lot about electromagnetic interactions and physics.
9:53
We've talked about how AC circuits change voltage, but let's take a deeper look.
8:18
Getting power at home is pretty amazing – and much more complicated than it may seem.
