Why settle for the least bad one when you can vote for a party that will end the government hush-up on extraterrestials, outlaw chemtrails, and make perpetuum mobile energy available for everyone? [see SOPN.nl]
Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
The 'you change the system by measuring it' is called the observer effect, and it has to do with wave function collapse and not with uncertainty.
Regarding the HUP: you can derive that without referring to measurement apparatuses, by just looking at the momentum and position operators. Let position x and momentum p each have standard deviation dx and dp, respectively, then by the Cauchy-Schwarz inequality
dx dp >= |cov(x,p)|.
The covariance of x and p is
cov(x,p) = E[(x-E[x])(p-E[p])],
where E[A] is the expected value of operator A, and as the commutator of operators x and p is [x,p]=i hbar,
dx dp >= |E[(x-E[x])(p-E[p])]| = |E[xp]-E[px]|/2 = hbar/2,
which is the Heisenberg uncertainty principle.
... I'll just aim for an Ig Nobel Prize instead.

I would say that the invention of the sun valve (Gustaf Dalen, Nobel prize for physics in 1912) was a pure engineering achievement.
When I was in (Dutch) secondary school, textbooks used to be around €50, so that’s a little cheaper than university but still way over $25. Secondary school students can usually rent their books from the school here instead of having to buy them themselves, so that brings the total cost down to about €10 per book for the student.
I can’t remember any of my textbooks costing around $25. I think $100 (€75) is the mean price.
Of course, this only validates their argument: if you are willing to spend $100 on a textbook, spending $25 on a pc for education is not a big hurdle.

No it doesnâ(TM)t. Kilograms are a unit of mass, not of weight.
After all, he lived in a white house for a few years.
I wonder which they'll allow first when they run out of 'old' pantheons: planet Xena or planet Jesus. No troll intended, just wondering.
My suspicion is that Linux has much better hardware compatibility with Win2K era PCs than Vista does; and my suspicion is that the software compatibility of Wine vs Vista for Win2K apps is about the same. But before I make a recommendation that upgrading to Wine would be better than upgrading to Vista in our company, I wanted to Ask Slashdot to see what other people's experiences with either transition have been like. So far our company has no experience with Vista nor Wine/Linux (quite a bit of Win2K & Linux experience, though). Any experience you guys had moving ot to Vista or to Wine would be of interest.
Would an upgrade from Win2K to Vista or an upgrade from Win2K to Wine/Linux be less painful?"
