Here are ALL TEN global data sets included in one graph. Every single one shows warming. Can you seriously look at that and still claim no warming over the last 18 years?

The EPA guidelines are in line with the level of risk: very, very little. If you want to cut your mercury exposure, don't stop using CFLs, stop eating seafood.

As for the Bridges case, you should read the Maine EPA's account. CFLs were new back then, and they had decided to use her case to learn more about what sort of advice they should give for dealing with broken bulbs. So they sent someone with a meter because they wanted to learn more, not because that's standard practice. The carpet was already intended for removal as part of a rennovation. They took readings all over the room. The only place with "high" levels was right where the bulb broke - not in the ambient air, not anywhere else on the carpet, not on the toys, not even under the carpet where it broke. I say "high" because even the levels right where it broke weren't actually high, just over Maine's long-term exposure guidelines (which is obviously not applicable to a temporary event). Moving the meter even six to eight inches away rom the breakage point dropped the levels way down. She was told that the bulb breakage was "of negligible health concern". However "the homeowner expressed particular nervousness about exposures to mercury even in low numbers", so they told her what she could do if it bothered her, one of which was calling a cleanup contractor. And of course any private cleanup contractor will charge you an utter fortune. The Maine EPA came back two days later after the story hit the news, before anything had been done in the house. The area where the bulb broke had dropped down below Maine's limit.

The case was ridiculously blown out of proportion.

Or reuse your existing television.

You do if all you have is a phone or an iPad brand tablet or both. One of my coworkers has no computer at home.

At 100 km/h with seamless handoff from one cell to another, or just at walking speeds in a single cell the size of an apartment?

Would you consider voting out the incumbents?

It's the only voting strategy that can make a difference, the only one that matters.

When congressmen realize that they can be voted out after a single term, we'll have pro-public policies.

And the best part is it's completely anonymous! No registration, no donations, no E-mail lists, no paper trail. Just resolve that "if this doesn't go in favor of the people, I'm voting against the incumbents".

Join the boot party - give 'em the boot!

(P.S. - Pass this along)

Yeah you guys in the US by definition of who you elected decided you didn't want our "dirty oil." That's fine we'll sell it to asia and europe.

I said centripital when I meant centrifugal I guess and started a long subthread / argument basically about nothing. I understand gravity is the centripital force in an orbit. The balancing, opposite force is what I was calling centripital.

I think it refers to a controversy in 2012 where certain ground beef producers were padding their products with so-called lean finely textured beef.

Let me make sure I understand what you believe they are right about. You're saying that earth's gravity causes centripetal force?
So in deep space, away from earth's gravity, there is no such thing as centripetal force? If you fly a sharp curve in deep space, your own momentum won't press you against the outer wall of your ship?

Centripetal force acts enough like like gravity that Einstein theorized it involves the same underlying force as gravity. It's not EARTH'S gravity. Centripetal force exists in deep space, far from the influence of earth's gravity. Because it acts just like gravity does, it can perfectly balance out gravity, with -1G of centripetal force exactly counteracting +1G of gravity, resulting in 0G net.

I did read what you wrote. What I'm talking about is more general, it applies even to a perfectly homogeneous gravitational body.
I'm talking about the minimum gravitational altitude in terms of \frac{Gm_1m_2}{r^2}=\frac{m_2v_{T}^2}{r}.

The architecture of Google is utterly useless for many businesses cases.There are many use cases where it'd be perfectly appropriate.

In most cases, businesses don't really care about accurate answers to queries; they want quick, more-or-less correct answers. For example, suppose Amazon has a dashboard that shows their book sales on an hourly basis. Timeliness is more important than exactness here, and answers more precise than the pixel resolution of the graph on the big TV are wasted. A "big data" style query that is 99% correct and runs in 5 seconds is much more valuable here than the exact answer that returns in 2 hours.

For accounting types of reporting, slow, exact architectures are probably more appropriate. For realtime analytics, a best guess that comes back immediately may be the right thing.
