Why is there only one monopolies and mergers committee?
That's the place. And I live right on the river about 20 yards from the Danube bike path.
Great answer. Reminds me of the explaination for why some sliding "fifteen puzzles" cannot be solved. My thought was that it is a trick question. A mirror doesn't reverse left and right at all but instead reverses "front and back" i.e. causes all molecules to morph into reverse in a horribly grotesque way.The left/right reverse is an illusion.In three dimensions you can have a right-handed coordinate system and a left-handed coordinate system.

Two of the three axes will be in the same plane, a 3rd one will be offset - say 90 degrees, but could be anything that isn't coplanar. You can flip one of these three axes to get a different system. You can't 'reverse' two directions at the same time and end up with a different coordinate system. If you reverse say y and z you still get the same coordinate system just rotated around wrt one axis. If I reverse either 1 or 3 I end up with the other coordinate system! So reversing two doesn't work. I hope that's correct and isn't total gibberish (possible).
That always confused me with Star Trek. Whenever the Enterprise meets another ship, they're always the same way up!! How do they manage that?When out on a spacewalk attached to a space ship, which way is up?
Ha ha - I'd never thought of that one - you're right!That always confused me with Star Trek. Whenever the Enterprise meets another ship, they're always the same way up!! How do they manage that?
Surely one of them would be upside down, or at an angle or something???
Ha ha - I'd never thought of that one - you're right!
I also used to wonder about the transporter ... If the person operating it got the landing coordinates a few inches low, your feet would end up fused with the ground or the structure of the ship you were transporting to. If you materialised a few inches too high up, you'd fall and stumble! (Or - bearing in mind the orientation question - you might land on your head!)
They once ended up with two Rikers IIRC. As if one wasn't annoying enough...
