Jim Al-Khallili is presenting a programme on quantum physics BBC4 9/12/14 at 9pm  I think.

Dead or alive you might be there (cats optional)

But does it have 'Fluffy Bunnies'.

All telly nowadays has to have non-sense 'Fluffy Bunnies'.

Zoom in zoom out, keep repeating the graphics, have subjects in that look pretty and have colours, I could go on and on, or maybe I am just getting an 'Old Git'.

Thanks for heads up Desp. Will give it a go. His programs are normally less dumbed down than most.

Edit.
Drat. Just seen the date for the program. Can't set the machine that far ahead and have a memory like a sieve. Desp can you bump this closer to the time  Smiley

You see that concerns me a bit.
 The spacetime of our universe is usually interpreted from a Euclidean space perspective, which regards space as consisting of three dimensions, and time as consisting of one dimension, the "fourth dimension". By combining space and time into a single manifold called Minkowski space, physicists have significantly simplified a large number of physical theories, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels.

In non-relativistic classical mechanics, the use of Euclidean space instead of spacetime is appropriate, as time is treated as universal and constant, being independent of the state of motion of an observer. In relativistic contexts, time cannot be separated from the three dimensions of space, because the observed rate at which time passes for an object depends on the object's velocity relative to the observer and also on the strength of gravitational fields, which can slow the passage of time for an object as seen by an observer outside the field.

So bearing this in mind that I am sitting in my chair when should I set the recorder? Grin

Blimey Bo, Tod's uncovered  a real conundrum..............

You see in the first scenario you might have to set your alarm on the phone to remind you to programme your video recorder at some specific time in the future so that you don't forget to remember, otherwise you may well remember to forget and we could all end up in the future having seen nothing at all. Or something?

In the second it might be that if we try to specify a future time at some place in space ,IE your recorder, we must do it slooowly and using as light a touch as possible to minimise the risk of slowing time  down. If that were to happen we could very well wait donkeys years before we need to set the recorder or before the programme is broadcast, it might even be just as probable the we speed up time in which case it could be just a few milli-donkeys or even micro-donkeys before the programme.

Oh god I don't know, it might be safer to forget the whole thing................ sh*tfan facepalm

I wonder how long a Donkeys year is?? tumble

I really enjoy watching 'through the wormhole' - watched an episode this evening. Although a lot of what's covered is old stuff, they do always include plenty of modern and often wacky theories. There is usually something that gets me thinking, and usually something that I haven't read of previously - tonight, the one that made me think, was the concept of time as 'grains' or 'atoms of time' - certainly made a lot of sense, and got me thinking about dark energy - maybe it is simply 'time', being created.
