A Night with the Stars Trailers

For one night only, Professor Brian Cox goes unplugged in a specially recorded programme from the lecture theatre of the Royal Institution of Great Britain. In his own inimitable style, Brian takes an audience of famous faces, scientists and members of the public on a journey through some of the most challenging concepts in physics. With the help of Jonathan Ross, Simon Pegg, Sarah Millican and James May, Brian shows how diamonds - the hardest material in nature - are made up of nothingness; how things can be in an infinite number of places at once; why everything we see or touch in the universe exists; and how a diamond in the heart of London is in communication with the largest diamond in the cosmos.

The adorable Brian Cox attempts to explain quantum physics to a roomful of assorted people at the Royal Institution, presumably many of the people "stars" in the celebrity sense.Brian gets audience participation in some experiments, such as a recreation of the double-slit experiment, igniting hydrogen, producing standing waves in a spring, and performing math.As a sort of ad for following up on some of the concepts presented, maybe it works. I'm not sure. But I don't think it's much use for learning. Brian's previous work is better for that goal. These topics take time. The fun in science isn't about flames and games; it's about how interesting our world really is.I am already familiar (as a viewer of science programs, not as a student or expert) with many of these ideas, and yet I remained unconvinced by the presentation. For example, the double-slit experiment was a disappointment. After hyping it, all that really happened was some sand went through two slits into two piles. We saw an overhead view of a water wave version of the double-slit experiment (but it crucially omitted the detector's view). Then we were shown a recording of the electron experiment instead of actually doing it as was suggested would happen. I don't think the audience even knew what they were supposed to be convinced of, after that.One key question that I am left with is how the Pauli exclusion principle means that no two elections anywhere in the universe can be in exactly the same quantum state, and that modifying the state of some electrons here means that electrons all throughout the universe must instantaneously adapt to this new change, to avoid being in exactly the same state. For example, heating the atoms in the £1000000 diamond immediately affects those in a white dwarf star (BPM 37093, I think). Does this happen at the speed of light? Is it faster than light (instantaneous, as suggested)? These questions were not discussed.I do appreciate Brian's statements to the effect that things like the Heisenberg Uncertainty Principle and the overall weirdness of quantum physics don't mean physics is impossible, or made-up nonsense, or license for all manner of "woo woo". Some audiences need to be reminded of this more often.One part I did benefit from was the reasoning that while it was almost certain that the diamond would never spontaneously move from its box, by focusing only on a few of the atoms and shrinking the box ever smaller (disregarding what it's made of) the math leads to a conclusion that not only makes this relocation more likely on the small scale, but inevitable.This lecture is not a bad way to spend your time. But it may not be useful. There is more in-depth information out there, from Brian Cox, and others.
