I was just wondering.....
I was just relaxing and watching episode eight from series eight (Hypothetical) and came upon the hypothetical question about how you would describe left and right, by use of words alone, to an alien over just a radio transmission.
I was semi satisfied with all the arguments but the definitive answer given by Stephen was that there was no actual way, without having a spacial reference point that we could both use.
I disagree on this and this is the simple and small amount of words I would use.
"Take both your hands. Raise them in the air in front of you, palms out. Bend the pinkie to middle fingers downwards and straighten the thumbs.
The hand that makes the shape of an 'L' is the left one"
Easy enough to describe with words alone I think.
Keep up the wonderful quality programming and Merry Christmas one and all.
