Comment Re:Fukushima Residents and Farmers Disagree (Score 5, Insightful) 201

What a relief! I wonder when they'll start moving people back into Fukushima Prefecture.

Fukushima prefecture is 14500 km2 and 2M inhabitants less than 8% of the territory and 3.5% of population have been evacuated.

I can't wait to sink my teeth into some Fukushima vegetables and I know you feel the same way

Most of the japanese would be perfectly OK eating food from Fukushima prefecture without fear-mongering idiots scaring a gullible population with occasional radiations level in food lower than one would find in a simple banana or brazil nut.

When do you suppose that 12 mile radius exclusion zone will be lifted? This decade or next?

Exclusion will be lifted next year for all areas with less than 20mSv/y of radiations level, that's more 80% of the evacuated area. Also half the radiations are due to Cs-134 with a half-life of 2 years. That mean all zones will be available in less than a decade, including municipalities like Namie or Iitate.

Now that we've decided that the maximum radiation dosage for a Japanese child is the same as an American nuclear worker, it's only a matter of time before they play in the shadow of Fukushima again!

There's a big difference between what you are allowed to receive every years during your carreer and a maximum environmental exposure that could hypothetically only happen one year. I'm sure the inhabitants of Ramsar who live with a natural radioactivity level of more than 100mSv/y would be laughing a lot at this.

And let's not forget how much better Tokyo is with 30% less electricity.

Yeah sure I wonder how any other energy production facilities would have fared facing the same earthquake and tsunami. Do you really think the Japanese government will be dumb enough to replace nuclear plants with tenth os thousands of off-shore tsunami-proof windmills ...

Submission + - Russian Scientist Discovers Giant Methane Plumes i (independent.co.uk)

thomst writes: Russian scientist Igor Semiletov of the International Arctic Research Centre at the University of Alaska Fairbanks revealed in an interview with The Independent that his team discovered "powerful and impressive seeping structures (of Methane gas) more than 1,000 metres in diameter" during their survey of the Arctic Ocean earlier this year. "I was most impressed by the sheer scale and the high density of the plumes. Over a relatively small area we found more than 100, but over a wider area there should be thousands of them," Semiletov told The Independent's Steve Connor. This finding is important because methane is estimated to be 20 times as potent as carbon dioxide as a greenhouse gas, and it could indicate that global warming is about to accelerate dramatically.

Comment Journalism at its best as usual ... (Score 3, Informative) 95

So this is a computation using a statistical model to give estimates of the soil contamination, and it becomes facts and measured quantities in the ground. But worse, look at the original scale provided by the authors of the paper: it clearly shows the areas under 2500Bq/kg, but the journalist conveniently merged it with the upper-bound area and also avoided the use of the green/blue colors usually associated with safe values in any mapping. Maybe the original map had not enough red and orange area for effective scare-mongering ? BBC I am disappointed...

> Energy from the sun is free, and it would be unethical to charge people to use the Strawberry Tree
*facepalm* And this "Strawberry Tree", was it free too ? The materials, the space used ? Will the maintenance be delivered by faeries during the night ? It would probably be better to inspire young people about what is economy and most importantly what is an environmental life-cycle analysis. I'm betting this gizmo has a far worse environmental footprint than the electricity from the Serbian grid.

Comment Re:You can never rule out risks completely (Score 1) 436

The problem with nuclear reactors is that when things go wrong, it goes wrong in a way that's very hard to control and can have an enormous impact on the health of entire generations.

Are you aware that the casualties related to the Fukushima plant accident are zero ? OK I'll grant you that maybe some operators at the plant may have decreased their lifespan of a few months due to a statistically significant increased risk of cancer, but that's hardly an "enormous impact" on the health of an "entire" generation. Please avoid the usual scaremongering headlines of the mass media regarding health and nuclear energy and remember that when deaths are accounted for energy produced, nuclear energy is the safest source we have around even compared with "renewable" energies.

This is really StarTreck futurism: considering huge improvements in spacefaring techs but with humans beings still stagnating in present biological and cultural levels ... IVF and ectogenesis would be efficient by this time. Even better, extreme longevity would be also granted since it is a precursor to the techs allowing bone loss regeneration and resistance to increased ionizing radiations damage. Space is for transhumans & robots ... Not the likes of captain Kirk guys.

Euler's Partition Function Theory Finished 117

universegeek writes "Mathematician Ken Ono, from Emory, has solved a 250-year-old problem: how to exactly and explicitly generate partition numbers. Ono and colleagues were able to finally do this by realizing that the pattern of partition numbers is fractal (PDF). This pattern allowed them to find a finite, algebraic formula, which is like striking oil in mathematics."
