No doubt, Discovery Science is a very good and innovating science channel. All the programs here are very good and we can learn alot from them.
We can get to know about all the things which we should from it. Time warp, How it's made, How do they do it, The Gadget Show, Food Factory, etc. From these my personal favorite is Time Warp.
The shows are very good and inspiring for me. And these programs not only inspire you but also give you knowledge out of the books.
