Quantum jump
I�ll start with a seemingly random series of stuff that�s happened (or is going to happen) to me, and then explain their relevance.
Number 1. I spent much of December sitting behind a desk. The downside is apparent to anyone who has to sit behind a desk. The upside is that I got paid for it, and so am now the proud owner of some money.
Number 2. Every Christmas, Kindle have an event called The 12 Days of Kindle. This involves reducing the price of many great titles to (usually) 99p. A title called �How to Teach Quantum Physics to Your Dog� caught my eye, and I�ve been reading it with interest. It taught me one thing: There are two types of people, those who don�t know what quantum physics does, and don�t understand how it does it, and those who DO know what quantum physics does, and don�t understand how it does it. Thanks to the book, I�m moving from the former camp to the latter. I will hasten to point out that I�m not some scientific genius (though I did get a Physics A-level). The concepts are not beyond any reasonably scholarly person. Read it � you�ll see what I mean.
Number 3 � The Radio Times hit the doormat of OfClayton Towers yesterday. On the cover was a big picture of Professor Brian �all the men want to be him, all the women want to be with him� Cox, advertising the upcoming �Stargazing Live� TV event. They did this a while back. Very good telly. Very interesting. Made me want to get involved.
Number 4 � I�ve been watching a few episodes of the wonderfully funny Frasier. Classic comedy. US TV at its best.
Number 5 - I live in the sleepy little village of Aquis-of-the-Romans, which is inconveniently located at the arse end of nowhere!
So, how are these all connected? Well, seeing Frasier (who has a nice refractor telescope, seemingly only ever used to observe people in neighbouring apartment blocks), made me realise how much I�ve always wanted a telescope. And now Stargazing Live is due on our TV screens just at the time when I have some money in my pocket. Bad timing! I should seriously consider using that money to buy food, water, a roof over my head, brake pads for the GhostMobile, etc. etc. However, I still find myself pricing up telescopes, and looking up at the un-light-polluted night sky above Aquis-of-the-Romans wondering about the bejewelled firmament that could be just a couple of lenses and a mirror away.
What has that to do with Quantum Physics? I hear you ask. Well, in order to explain, I�ll have to teach you something about quantum physics. This is why I mentioned I had an A-level in Physics earlier. It wasn�t to blow my own trumpet, far from it. It was to highlight the fact that I�m in no position to teach even classical physics, let alone quantum physics. But I will, anyway (what a rebel!) One of the enigmas in quantum physics is that particles like photons, electrons, etc, behave like a wave and as a particle. These are mutually exclusive, but they happen. Go figure! The upshot of this is that, if you take, say, a photon and send it somewhere, it can take any number of different routes to get there. It doesn�t just take one of them, it takes them all, though some of them are more probable than others, and plotting just how probable creates something that behaves like a wave. I didn�t state that very well, and any respectable physicist would sneer, but it will do for the purposes of this blog.
Because of this, and other incongruous aspects of quantum physics, there have been many attempts to interpret why there is this seemingly so counter-intuitive behaviour at the microscopic level. One such interpretation is known as the Many Worlds interpretation. We�ve all seen the Star Trek episode where Evil Spock arrives from a parallel universe (you can tell he�s evil, because he has a goatee beard!) The physics underpinning parallel universes is this Many Worlds Interpretation. We�ve said that our photon could take any number of possible routes � countless quadrillions of them. In the MWI, the photon takes all of them, but each one seeds a new future (or parallel universe, if you will). Now imagine how many photons there have been in the whole universe since the dawn of time. How many times they have branched into these countless quadrillions of new universes, and each of those new universes instantly branching into countless quadrillions of new universes. Yikes!
Anyway, I reflected on this, and found myself thinking thus. In the multiverse (the term coined for the collected whole of all these universes), there must be incalculable numbers of GhostOfClaytons, who think �sod it!�, and blow all their money on a telescope they can ill afford. Given just how many of them there are (countless quadrillions), surely I would be forgiven for taking the plunge, wouldn�t I?
