In real terms (PPP), for the vast majority of the population, there has been no economic growth in the west since the 80s. All the economic benefits since then have accrued only to the wealthy elite.

So the current system is clearly failing - it is not delivering benefit to society.

Paediatricians don't recommend the use of these devices. They haven't been shown to decrease the risk of anything. They tend to produce false alarms, causing a hell of a lot of parent anxiety, and which may contribute to post-natal depression (which has got a well established link to infant death).

All this rule changes is the efficiency for NEW wood burning stoves. It doesn't make them even cost any more. It just means they run more efficiently and put out less smoke. Pre-existing stoves don't need to be pulled out or anything.

So for the rural poor that means less cost for heating (or work of chopping wood if you prefer), and less lung disease, for really no increased cost.

Can't see that as a bad thing.

I wish I could get this rule to work with my 2 and 4 kids. Even better don't touch anything! and don't talk either!

Good luck enforcing that one.

Cool! So that's an open invitation to jailbreak their devices and develop a secondary resale market for itunes purchases then?

Why would apple want anyone to stick it to the man?

Is a series of sequel movies to deep impact -- featuring Mars!

All the graphics, none of the emotional impact.

"I see you are trying to ruin the company, would you like help with that" - FTFY

No permission slip would make any difference to being sued.

You can't transmit information with quantum entanglement.

It's like this - you have one very long coin which stretches between one place and another.
At some point you toss it, and it lands either heads up or down. At the other location you try to toss it, but it's already landed, so you see the result.

You don't know at which point in time the other end has been tossed, just that the two results are the same in the end, so it can't be used for communication.

That's interesting.

Now how about some research on actually persuading your child to have a nap, rather than a protracted battle of wills that gets everyone on edge.

Naps are great when they happen, but all parties must be willing

Deorbit delta V is zero if you wait a while.

Why is the shin - the area of the body the most likely to get bashed into things - not protected by a fat pad? And why does it have such a poor blood supply?
Why do hips - which bear the weight of the whole body - have a 90 degree bend in them?
What's with the appendix?
Why have testis outside the body, where they can be bashed easily
Why do the ovaries not have a complete covering? (deadly ectopic pregnancies)
Why is the appendix there at all?

That's just a few working bottom up. I could go on.

The JAMA is the journal of the AMA, the doctor's union.

It exists to promote doctor's interests. If it wasn't doing so it would be doing the wrong thing.

More to the point - head and neck cancer is very rare. Heart disease kills one in three.

So reduce a very rare risk in order to increase a very common risk, plus suffer tooth decay as well? Seems like a pretty poor trade to me.

Hang on a moment... TFA isn't talking about vaporizing - turning water to steam. It's talking about ionizing, which is clearly going to require a much bigger quantity of energy.

For actual vaporization, making a very rough calculation - 60kg person, 2,270 kJ/kg latent heat of vaporization of water = 136 MJ,
Sure there's specific heat to add in there too, but the vaporization of water is the dominant term, so it's at least out by an order of magnitude.

Lesson learned - don't try and be 'all sciency' and use the wrong jargon!
