Ah, the proverbial question … and one that Horizon on BBC 2 and BBC HD tried to answer on Tuesday.
Hosted by Alan Davies, the show looked at what it meant to try to measure something and how measuring it might actually alter reality. Mind-bending stuff but really interesting!
There is one final broadcast on BBC 1 next Tuesday at 2:35am! Apart from that, previous episodes of the 2009-2010 series are currently available on iPlayer but only for a few more days.
If you’ve got Media Centre and you want to catch Horizon next time it is broadcast, why not add a new entry to the schedule using the search feature? If you don’t know how to do that, watch this blog for an upcoming entry that will take you through it step by step.
Oh, and the answer to the question varied a few times but my favourite was “infinity”.
