Comment Re:Thanks, Space Shuttle (Score 2) 227

There's only one thing learned from the Shuttle debacle. Namely, don't let NASA build and fly its own launch vehicle.

The shuttle was a bit of a boondoggle, but you are blaming NASA, when in all honesty it had many congress-critters and Air-force fingers involved in its design and deployment. It's rather disingenuous to place all the decision responsibility solely in the hands of NASA.

-90% of German (or American) plants would not withstand impact of a plane bigger than a Cessna

False:
In the United States, the design and thickness of the containment and the missile shield are governed by federal regulations (10 CFR 50.55a), and must be strong enough to withstand the impact of a fully loaded passenger airliner without rupture. http://www.nrc.gov/reading-rm/doc-collections/cfr/part050/part050-0055a.html/

Submission + - Ask Slashdot: Physics of Water 1

bwayne314 writes: We have been having a debate at the lab about mechanics of water and leaky bottles that I am hoping you slashdotters might be able to put to rest.

One group claims that capping a bottle or tube with water residue on the seal will cause some water molecules to remain in the seal and allow liquid from the container to leak out (under certain conditions, like shipping) despite being tightly closed. They call this phenomenon, "creating a river" and opening and drying of the the seal on such a bottle would prevent a leak.

The other faction thinks that any bottle that leaks, simply has a poorly fitting seal and that closing a wet bottle with a proper seal should push any water residue either into or out of the bottle. The distinction here is that there should not be a difference between capping a bottle that is dry vs. capping one that is wet.

So what happens on a molecular level in this situation and who is correct?

You don't think building a satellite that can withstand the harshness of space, using the best tech that was available at the time back before the 2004 launch date, (it was built long before then) and results are still being evaluated, and .... there was no foresight??? Wow. Seems to me there were some smart cookies that work on these things and they thought a lot of this through as best they could using "decades of research and testing" to their best advantage. Oh, that's right, its USA, bash on.

Submission + - New Fabric Blocks Sound But Lets Light Through (gizmag.com)

Zothecula writes: Heavy curtains made from thick material such as velvet are often needed to keep noise out of indoor environments, but Swiss researchers have come up with another option. The Empa researchers, in collaboration with textile designer Annette Douglas and silk weavers Weisbrod-Zurrer AG, have developed lightweight, translucent curtains which are five times more effective at absorbing sound than their conventional counterparts.

I was really thinking of a 'Phone Home' system. I've been stuck with the task of licensing software before, and I had to be honest with management (showing them how many DRM systems have been broken before) that all licensing systems rely on security through obscurity in the end... since you have to give them the software/content to begin with. That was rather uncomfortable for me, but it was the honest truth. I didn't really have a comment regarding chip producers, so maybe I'm off-topic on that idea.
