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.

## Comment Re:Price of a textbook. (Score 1)349

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.

## Comment Price of a textbook. (Score 0)349

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.

## Submission + - ZFS committed to the FreeBSD base

An anonymous reader writes: ZFS has been committed to FreeBSD base few days back. This is great news and shows very much needed progress to maintain large data storages with commodity hardware. Linux port (ZFS on FUSE/Linux) is progressing too, but the native ZFS port for Linux kernel will still be graved by many.

## Submission + - Is Wine or Vista more Windows compatible?

ZMXJ writes: We've been hearing quite a few anecdotes & reviews that complain about poor compatibility of old hardware and pre-vista-windows software with Vista; and quite a few articles about improved compatibility of Wine.

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?
