Friendly way to learn something difficult - physics

I have written here the other day about the BBC programme presented/hosted by Jim Al-Khalili.
Back then he presented basic chemistry (see details here>)

At present I was able to watch on BBC4 the series about the electricity (electrons, waves, current). He speaks about the subject with such a passion that it is not possible to pass by this programme without a positive emotions. These are not easy subjects: either chemistry or physics, but from this man we can get a lot of interesting things, and learn a lot in a very pleasant and friendly way.

I truly recommend these programs one more time! Details here >
