The only reason I'd really be worried about the magnetic field flipping is that a changing magnetic field induces a current in a conductor. This means every electronic and electrical device with a closed loop would experience a large current, likely destroying the smaller equipment.
The earth's magnetic field is about half a gauss at the surface. It's weaker than the field generated by a refrigerator magnet. I think it's safe to say that the flip is not gonna destroy your electronics.
TiO2 nanoparticles are poison in that case (as a sunscreen ingredient) because they're being applied directly to the skin and exposed to UV. That means the skin is being exposed to hydroxyl and oxygen ions. In the case of the paint, it's not an issue. Those radicals have a pretty short lifetime, and production stops when you block the light source, so the paint should be perfectly safe to touch. Between the time that your hand blocks the light and the time it actually touches the surface, all of the dangerous stuff should be gone.
There's not enough energy for sufficiently complex chemistry; the sun's too far away, it's too cold, and Titan doesn't get significantly Io or Europa-style tidal heating. It's 100 degrees Kelvin on Titan... Not gonna happen.
There's not enough energy for complex reactions to happen quickly, but they can still happen. And there's nothing that says life has to be able to form there today. Assuming it has a large, rocky core, it must've gone through a long cooling phase after forming, so there would have been significant geothermal energy at some point. It's also a pretty crowded orbit. Collisions would provide at least short term heating; there's no reason it has to happen all at once.
The reason is, and I don't care if I'm modded down to -1, some mods would rather bitch slap people than do actual work like thinking and reading post. Some mods use it to suppress differing opinion.
I just don't get it. When I have mod points I look for good stuff to mod up.
That's funny. I usually waste my mod points modding down posts that start with variations on "Go ahead and mod me down." I guess this is your lucky day.
They've just stopped supporting it. They don't even have 64 bit drivers. Apparently they have no intention of releasing them ever. Seriously, XP x64 came out, what, 3 years ago? They just expect you to accept a crippled device that can't sync by USB.
On top of that, they leave out a lot of software that should be included for basic functionality. Their sync software doesn't address memory cards. The best you can do is upload to the card, assuming the file type you're transferring is supported by a program installed on the device. You have to buy a program to let your computer recognize installed memory cards as a flash memory storage device. How much would it cost them to snatch up one of the little companies that makes one of these programs and install it by default?
It's pretty clear they've moved on. I'm guessing they just plan to cruise along with no development expenditures for as long as they can before the market dries up and they get bought by a competitor.
I don't know about everyone else but my Ti-83 still works after 10 years of abuse. Those are some hard calculators to break.
Dropped my TI-85 down a two-story flight of steel stairs, after which it bounced across an asphalt parking lot. That was 9 years ago, and it still works.
This same article could've been written about Blackberries 5 years ago, or Palm Pilots 10 years ago, or laptops 20 years ago, or personal calendars 100 years ago. They just used iPhone to grab attention, which pretty much instantly lowers their credibility.
Ten times is a big exaggeration. Silicon has 10 times the specific capacity of carbon, which is the most commonly used electrode material, but that's just one piece of the battery. They're ignoring the current collector, insertion compound, electrode separator, packaging, and control electronics. It's still an improvement, but nowhere near 10X.
Either way, I have a hard time believing these things have a stable capacity after cycling. Fracturing is not the only problem in silicon electrodes. As the lithium is released, the swollen silicon structures tend to fuse to neighboring structures. Looking at the SEM images included in the article, it seems pretty unlikely that the fibers wouldn't eventually fuse into one solid mass and completely lose capacity.
In case people don't know why the parent made that post - you can't make any sort of turn on red in the UK. Red means stop, and stop is what it means. No wiggle room.
This is completely off topic. Neither the article nor the gp had anything to do with red lights. It was about turning across oncoming traffic. In the US, that's a left turn, because you have to wait for a break in traffic on the left side of the road before you can go. In the UK, and any other place where they drive on the left side of the road, they would need to reduce right turns, which would have the same problem. I can't believe I had to explain that.
That wasn't entirely true. It was IBM-Sun, then Intel-TI. That actually still makes sense. AMD was on a different day from the other three, though. That's what I get for not double-checking before posting.
It looks like they went in groups, too. IBM, Sun, Intel, and TI all in one day. 3Com, Tandy, Unisys, and AMD on another. It probably wasn't an individual decision for each company. It'd be too much of a coincidence.
A good GMAT book doesn't teach you how to do the math. It teaches you how to take the test. It's more about speed tricks than a solid math foundation. Eliminate obviously bad answers, plug in other answers to see if they work, etc. A lot of that stuff is only applicable in multiple choice situations, which is not what this guy is looking for.
Your ISP is not an interactive computer service. If the filtering service were interactive, you'd be able to switch it on and off, or at least have some control over what's being filtered. If that's the case, what are you complaining about? Just turn it off. Otherwise, the law doesn't apply.
Cutting tuition will always improve the talent pool, because it removes an arbitrary obstacle. That's why the University of Georgia System has improved so dramatically in the last 10 years. The HOPE Scholarship made college so cheap that anybody can go, so the schools can all be a lot more selective.
In my high school (it was a Georgia public school), you had to have skipped 6th grade math to get to super-basic (no AP) calculus in high school. Otherwise, you topped out at trig. On top of that, trig was optional even for what they called "college prep" diplomas. Guess how many people were in that class. That was going on 15 years ago, though.
I recall King George of England scripted a similarly beautiful piece of writing in response to the colonies threatening to declare independence from Britain. That King George was later known for having lengthy conversations with trees...
I think it's safe to say GWB had no part in writing this order. In fact, I'd bet my remaining civil liberties on it.

I just feel like I should point this out before someone decides to go on a rant about embryonic SC.
If you were trying to avoid a debate, you failed spectacularly.

If we're being pedantic, it's a speed, not a velocity. Velocity is a vector, speed + direction.

It's in the Hardware section of Slashdot. It's right there in the address: hardware.slashdot.org. Why would you tag it hardware?

Next week we're renaming it South Hawaii.
If it makes you feel any better, it's really closer to 50%, and most of those people were douchebags.

Yeah. At random frequencies, and in random directions. What good is that?

Totally OT, but your sig is really bothering me. Please change it to "who WAS washing" to fix the glaring discrepancy in your alliteration.
How about some Tranzor Z?

It's from the movie. At the time, it was Mr. Garrison.
