There are two types of non-Newtonian fluids: rheopectic and thixotropic.
There are actually many types of non-Newtonian behaviour, of which shear thinning and shear thickening are two. Some materials (like porridge) have a YIELD STRESS - that means that a certain amount of force is needed before there is any flow at all - in other words, you can stand a spoon over at quite a large angle in a bowl and it won't move, but JUST past that critical angle it will move. Another good demo is a dilute solution of paraffin wax in paraffin (kerosene). If heated up gently, then cooled it, ir forms a solid, which resists flowing at all. Shock it and the "solid" shears instantly to a liquid !
Incidentally, cornstarch solutions are also electro-inspisative - they thicken with applied voltage. Great care is needed with THAT demo.
American culture has problems with xeno-relations? Bullcrap. You want to see xeno-relation problems? Try being a Catholic in Northern Ireland or a Muslim in Serbia....or a black guy in LA or a black guy in Alabama or.....
Where is all the carbon coming from ? I thought the remaining ash had no carbon left, you've been BURNT remember, the carbon has combined with oxygen and F%^&ed off up the chimney....
Would a program that is functionally identical have similar themes executed in different languages ? Could the ears detect dissonances as bugs ? The idea that being able to listen to a program allows some of the most powerful processing algorithms in our brains to work on a problem WHILE you are working on another section is fascinating . Most people who aren't tone deaf can mentally process a tune, and can tell instantly when its wrong.
On a budget of £60bn+ per year (what's that, $90bn?). Sure, it's an outrage, but Enron's fraud was one hell of a lot bigger than 3% of annual revenues..."
Sure, but this is every YEAR. The Enron thing is an aggregate number over several so far. The point is that the US financial scandals can't be buried and suppressed. The UK financial scandals are in PUBLIC organisations and being suppressed by government fiat.
Bear in mind the scale of fraud in the British National Health service has been investigated and the results supressed. Some estimates put the fraud in excess of $3 billion per year
BTW Stephen Baxter has some great hard sci-fi reading about alternate near futures...Titan is a great one about the collapse of NASA and a very technical description of a pieced together trip to Saturn's moon Titan, great read.
..or his book "An Engineer in Toyland".
Eric Laithwaite did all his linear motor stuff at Manchester University over 40 years ago. A giant in his field, and a genuinely nice bloke. I feel very priveleged to have met him. He died in 1997, just in time for Nasa to have approached him for this project.
Go with the PC104 or Single board PC idea - the embedded functionality is incredible. There are US vendors, but one of the best I know is "Inside Technology" You're looking at more than treble the price of a normal motherboard though. You could even make a Beowulf cluster that fitted in a shoe box though!

...or DVD hurts BO (main headline)
Wow, they can even cure BO digitally. Great news for Geeks.....

nahh You're missing the point.

Most depressing Sci-fi story I've ever read...

And lo, on the eigth day God created GZip compression and saw it was good. And it would bugger up any reverse engineering. DMCA or not.
