Sometimes it's very hard to see the way things are going, particularly when you realise that impossible things aren't really impossible at all, they are just bound by today's actual perceptions rather than the unrevealed laws of physics being worked out before our eyes.
Class 1 impossibilities are technologies impossible today that do not defy the current laws of physics: teleportation and psychokinesis are examples.
Class 2 impossibilities are those at the edge of our present understanding: time travel and hyperspace transportation and the like(?).
Class 3 impossibilities are a bit further out still (but seem closer than you might think in an odd, circular way): perpetual motion and precognition (seeing into the future).
There may of course be a Class 4 series, as yet unmapped and even more scary: Cracking an egg without breaking the yolk , getting itunes to work properly, a cure for snoring and making the perfect cup of coffee. All in theory possible with today's technology but as remote as plasma engines, nano-ships and space elevators.
The weekend's most interesting and best things:
The indiscriminate use of curling tongs.
Meet the Fockers for the third time.
Main meals, with wine(s) and puddings and all relatively civilised.
Ubuntu user trials are carried out in the "IS" proving grounds.
Podgy swift fledglings perch of the roof looking cute and hungry.
Dr Who comes to an almost satisfactory conclusion despite some wild speculation on my part.
The rain beats down upon a grey Fife coast as we travel across it's wide expanses and buy bird seed, magazines and jars of curry paste.
The Felice Brothers bang a hollow drum in a lengthy introduction.
Ten shirts ironed as the Tour de France runs across North West Brittany narrowly missing our front door.
Strumming chords and whispering songs by Steve Winwood.
Speeding up and slowing down and stopping, as happens during many experiments to do with improving our understanding of physics.
