The Clash of the Titans - part 1
The Key to the Cosmos - part 2
The Illusion of Reality - part 3
This is one of the best informative and interesting documentary I've seen. You will surely like it.
I think our high school teachers should see this before taking classes on Atomic physics, Elements, Astronomy etc.
P.S. Thanks to BBC for producing this documentary and Badri for sharing this information.
