Agreed! Although I am fully sighted, from childhood I would practice walking down dark hallways with eyes closed. The "sound shadows" you describe are only a part of it - an analogy that the sighted can grasp.
Local changes in reflectance and absorbance of sound as you navigate a 3-D space are also richly informative as to the shapes and types of surfaces around you, in addition to their locations. It is particularly powerful in a space with which you are familiar, like your home.
PZT is an extremely stable compound, and is not a significant environmental risk. It's an oxide, and it doesn't hydrate, so it's about like any other mineral in the ground. Structurally, the lead is locked up in a cage of TiO6 and ZrO6 polyhedra. It doesn't melt until >2000 degrees F. The lead in it isn't going anywhere.
Lead in paint? Bad - kids eat it.
Leas in solder? Bad - leaches in acidic soil.
Lead in PZT? Fine - it will stay there forever.
No, the article is talking about medical research, which is entirely different from research into the physical sciences (climate research included).
With medical research, it's impossible to get a big enough sample to be statistically conclusive, because you are dealing with people trying new drugs, so they don't die. It's hard to find enough desperate subjects. So, you're measuring how much of an effect something has, as best you can, with such a small sample. Anything one says about how it works is an educated guess.
In the physical sciences, however, you're dealing with measurements of firm physical quantities, and plenty of good-quality data. You have plenty of data, and there is no question about its accuracy. The question becomes one of why things work out as they do.
So, regarding climate change, the question is not whether the earth's atmosphere is warming. Data show clearly that it is. The question is how much of the heating is due to human activity.
In this (imaginary) case, the energy in would be that of the magnetic field. Trying to spin this as a possible supernova plays on ignorance, is scaremongering, and is just plain wrong.
Haven't the cell providers already been trying to sell extra apps for years? Mostly games. How many un-erase-able demos are on your cell phone?
Apple has opened the floodgates in yet another market. Delivering to customers what they actually want, instead of what some misguided "marketing" department would prefer to force down their throats.
blahplusplus: What really hits a nerve with me is why the scientific community hasn't opened up all their journals for others to read.
We scientists would absolutely love to have all of the journals opened up for free access to everyone. But, you see, the publishers own the copyright to our articles. The system requires us to give them the copyright, in order to get our stuff published. Then you, me, and everybody else has to pay to read recent research.
Thankfully, some established journals are going open-access.
That's very promising. But the fact remains that publishers such as Elsevier own the copyright to many decades-worth of scientific literature. And they're not about to give any of it away.

I don't think the ancient Greeks had licensed those particular fonts.
The feature is also in water a mile deep, lol.
...unmanned missions of exploration. Space probes and planetary probes.
They cost way less than manned missions, and return way more scientific information.
Hmmn, it does indeed have the feature in a menu.
But it doesn't show up in the Help files.
And if it is like any of the other features in Word, it probably has a bunch of heinous bugs that make it functionally useless.
Better to avoid it and just go to OO where the programmers actually try to make it work.

Sodium lights are the most efficient form of large-area lighting around.

This sounds like Michael Norris's Chunk Munger or Sample Hose, both released way back in 1996, when computer audio was really hard.
And sloooooooow.

Diamonds make girls easier to sleep with; tequila makes girls easier to sleep with. We really should have seen this earlier.
Wit and charm work much better, and don't wear off in a day. Cheaper, too!
Those signs cost about $0.50 each to print.
Pull them up. You will increase their costs. Every little bit counts!

They have everything. Good prices. Axles and bearing are not so expensive.

Yeas, this is totally an issue with medicinal research.
Not so much with the hard sciences of physics and chemistry, and these days biology as well.
Subby, please don't paint research with such a broad brush.
Actually, 18,000 gs would be more correct.
Big G is the gravitational constant, little g is 9.8 m/s^2.
Energy doesn't magically come from nowhere.

When did Slashdot turn into Fox News?

Other programs offered to treat PTSD include Virtual Airplane, Virtual Audiences, Virtual Heights, Virtual Storm, and Virtual Vietnam."
And for the slashdot crowd, Virtual Pick-up, Virtual Bar-scene, and Virtual Date.
Submitter is incorrect and misleading.
Blue and white LEDs are based on gallium nitride, not gallium arsenide. Completely different material.
GaN, not GaAs.
It's the arsenic that's bad. It is in some specialized non-consumer electronics, but it is most definitely NOT in LEDs.
This is all part of the process of science.
People are trying to figure out the unknown, and don't always get it right the first time.
The popular press may spin it differently for the layman, but this is how science works.

It's a lot easier on the eyes than a bright white field with black text. Don't try to print it out, though.
