According to the above, this channel is dedicated to the promotion of scientific knowledge. But, with all due respect to the United States copyright law, I will make a "fair use" of the material of others; here you will find nothing but short clips on one aspect of a documentary film. I will always suggest you to watch the original documentaries and I strongly believe you should.
