Comment Re:It be 12m above sea - max Tsunami: 7m (Score 1) 122

"the area" is the problem. Like I said, specific topology and history of the selected location, not the general area, is a very important consideration that you just conveniently gloss over.

Like I said, there was coastline in "the area" of the Tsunami in Japan that because of its topology did not see the amplitude that areas like the Fukushima coast did. Sorry if those details make your point more difficult, its simple fact.

Tsunami amplitude is a result of the topography of the ocean floor near the coastline and the shape of the coastline itself. All coastlines are exposed to tsunamis, but they only get very big in a limited number of places. Even in Japan, just short distances from the places where the tsunami did great damage, were other coastal areas that saw a much smaller wave height.

Yeah, they should start simple. "Do Laundry" is too big a task to start with. Just start with a useful subtask.... I'd like a robot that can sort socks. Throw clean ones in a hopper and out come matched pairs.... singles stay there and get matched later. Perfect that then add another feature.

Submission + - Homer Simpson Nearly Calculates Higgs Boson 14 years Before its Actual Discovery (latimes.com) 1

operator_error writes: In the episode, titled “The Wizard of Evergreen Terrace,” a mid-life crisis inspires Homer to become an inventor in the mold of Thomas Edison. One scene features him at a blackboard working on an equation to calculate the mass of a Higgs boson, the elusive subatomic particle that is key to understanding why objects in the universe have mass in the first place. (You can see a picture of the blackboard here.)

Simon Singh, a science writer with a doctorate in particle physics, crunched Homer’s numbers and declared that the usually hapless Homer got his math pretty much right.

“That equation predicts the mass of the Higgs boson” Singh told the Independent. “If you work it out, you get the mass of a Higgs boson that’s only a bit larger than the nano-mass of a Higgs boson actually is. It’s kind of amazing as Homer makes this prediction 14 years before it was discovered.”

Well, not exactly.

According to David Kaplan, a bona fide particle physicist at Johns Hopkins University, Homer’s equation yields a value of 777 gigaelectronvolts, or GeV. The actual value measured at the Large Hadron Collider is more like 125 GeV, plus or minus a GeV.

“It is a bit off, but not insanely so,” Kaplan said.

Homer would have done even better if he hadn’t made pi the first term in his equation, Kaplan added. Without it, he’d have had “a nice guess of 99 GeV, which would not have been too shabby,” he said.

Even so, 777 GeV was not outside the realm of possibility back in 1998 – at that time, the upper limit was thought to be around 850 GeV. Still, those in the know were already seeing evidence that the true mass of the Higgs was significantly lower, Kaplan explained.

The fourth line of Homer's equation appears to show how a doughnut can evolve into a spherical body that vaguely resembles the moon.

But it is not CF alone, although that is a very important factor. It is also design life, lifetime O&M, etc. Windmills don't last very long, new nuclear has a 60 year design life extendable to past 80 easily. Nuclear plants need fuel and parts replacement and staffing and regulatory and wast fees. Wind needs backup, there is a significant cost to that. Wind needs added a decentralized transmission infrastructure, a large generator can centralize it, there is a cost to that.

The systemic cost & value is what is most important.

The good thing about nuclear investment is much of the money stays at home. For solar, a big percentage goes straight to Chine. Also, nuclear plants generate thousands of high paying jobs over their lifetime, providing a social economic return not found in most renewables. The total 'societal economic return' of nuclear is much higher than renewables, which themselves must ride on the backs of conventional generation to be successful.
