    I only meant understanding what god is, or would be if he existed. He might be a product of as-yet undiscovered physics.

    It seems the more you know, the less you know. Which might make sense to a quantum physicist.

    On those occasions, according to Feynmann - you're wrong!

    I liked what someone said on the letters page of New Scientist this week, regarding wave particle duality. An electron is neither a wave nor a particle. It is an electron.
    I can't remember the term, but Hawking talks about how it's meaningless to talk about what an electron IS, only what models explain it.

    Or alterntaively I was right and wrong at the same time

    or I was right until I thought about it and then the wave form collapsed

    sometimes I think I understand it and sometimes it is elusive like a mote in the corner of my eye...

    And what about that infinite number of parallel universes?

    Or is that a different theory?

    There's some complex weave theory in there too.

    Not to mention a bit of Hennessy uncertainty

WTF??? Or did I misunderstand that wrong?

    Much as I love history programs I prefer to read what would be uni course content. I have an interest in Roman history (who doesn't), I did latin at school and that got me interested.

    More recently I read Prof Mary Beard's Pompeii and still correspond with her about questions I have about that particular time and a very knowledgeable lady she is and I'm grateful that she takes the time to answer my questions. What do we get on TV? A 'dramatised' version based on froth (not the BBC program the book was based on).

    I prefer to read Pliny although already translated as I can't do that.

    Anything that might get kids interested in science / maths is valid but the beeb have lost the plot along with other program makers who seem to assume that the raw subject is too difficult for most to understand and so dumb down the subject and in some instances turn it into short soundbites. Does this lead to contributing to a short attention span of the audience? I think so but it's anecdotal at best and I can't quantify that.

    The culture of x For Dummies doesn't help either, fully embrace a subject and explore or forever be bound by the summaries of wiki and Google searches.
