I always find these shows a bit slow and repetative, they also try to impress the viewer with half the story to make quantum ideas sound amazing, which they are, but they go a bitt ott.
Like telling you a particle can be in one place then on the other side of the universe in the next instant. Its not really like that, its a possibility, but such a small one it never happen. Altough Brian did actually run therough the maths to show this on one programme....
Its good, to share these ideas and understandings of things though, but it would be nice if a series of programmes went into more detail.
But perhaps thats what books and physics degrees are for.
