Obama calls for rational, fact based debate on important issues

Donald Trump, Orly Tate, others are “side show carnival barkers” and questions by birthers, others “silliness” according to Obama, in a press conference moments ago.

Following a down-and-dirty live statement to the press asking everyone to just shut. up. and get down to business on the important issues facing the nation, the press vowed to provide intensive, irrelevant and annoying coverage of the birth certificate issue all day and for the rest of the week. Presumably the story will be interleaved with coverage of some wedding going on in England.

Here’s a statement from the White House:

Japan Nuclear Disaster Update 21: The chickens come home to roost edition

The reactors at Fukushima continue to be hotter than “cold shutdown” levels, and at least one reactor (#1) is probably leaking from the core containment vessel. Fission products in high amounts, high pressure, and high temperature indicate that something close to fission is still happening although an apparent lack of large quantities of short lived isotopes may indicate that it has been a while since extensive fission has occurred in the leaking reactor.

There is still concern over possible hydrogen explosions and unexplained “white smoke” continues to rise from several buildings on site.

There is now concern that the spent storage pool for reactor #4 is leaking, and there is concern that it will not be possible to apply as much water as needed to some of the storage pools for fear that they will collapse. In addition, there is concern that applying too much water to at least one of the rectors is causing structural decay of the building that will make it collapse if there is an earthquake.

There is real progress in hooking up the plants to outside power sources, and in fact, it will eventually be connected to redundant outside power sources. The degree to which this is completed is unclear.

Tens of thousands of domestic animals (chickens being the most abundant, but also cattle and swine) have died from neglect in the evacuation zone, and government officials are now starting the process of euthanasia on some of the rest of them. Local civic leaders have reached a state of depression and despair and collectively state that recovery of the affected communities is impossible.

One of the most interesting recent outcomes of this event (aside from the fascinating engineering and nuclear physics) is the call to prosecute judges that adjudicated the regulatory process early on in licensing of this and other nuclear power plants in Japan. The claim is being made that Judges sided with the Nuclear Power Industry on issues of safety. The reason this is so interesting is that Nuclear Power Apologists have used a number of techniques to support certain decisions related to Nuclear Power Plant design, construction, operation, and licensing which would likely be exposed and debunked as part of such an investigation and trial. This is a potentially very positive thing for those of us who consider ourselves rationalists and skeptics. A critical examination of how we integrate scientific knowledge and engineering with the development of energy policy in the broader context of political policy would be very productive.

And in doing so, it would be very important to re-examine Chernobyl. The current widespread belief regarding Chernobyl falls into two categories: 1) It was a horrid disaster in which thousands died and/or got cancer and 2) Nothing really bad happened outside the site of the fire itself. The former is the view of the anti-nuclear pole, the latter of the Nuclear Power Apologists. Neither is true. It will be necessary to get Chernobyl figured out and on the table as part of the process of examining Fukushima.

And now, Ana’s Feed:

Co-op sells banned spinach to consumers in eastern Japan – April 21, Kyodo
-A Tokyo-based cooperative has delivered spinach grown in the town of Tako, Chiba Prefecture, to consumers in three eastern Japan prefectures despite a government ban on shipments due to concerns about radiation, the Chiba prefectural government said Thursday.

Radiation over 100 microsieverts detected 2-3 km from troubled plant – Kyodo

  • Radiation levels of over 100 microsieverts per hour were measured at four locations 2 to 3 kilometers from the crippled Fukushima Daiichi nuclear plant from late last month, the science ministry said Thursday as it released such data for the first time.
  • All four readings of over 100 microsieverts were taken in the town of Okuma in Fukushima Prefecture, and about 2 to 3 km from the nuclear plant, with the highest reading of 124 microsieverts measured at a location around 2 km west-northwest of the complex.


The Chernobyl deniers use far too simple a measure of radiation risk – The Guardian: Those who downplay the dangers of nuclear energy are wrong to focus only on dose.

  • “In his article on “the confusing world of radiation exposure”, readers’ editor Chris Elliott was right to point out that getting a whole year’s sunshine in an hour would fry him to a crisp (Open door, 4 April). Radiation dose rate is important. What he didn’t say is that “dose density” is important too.
  • The “sievert”, as Elliott says, is a dose unit for quantifying radiation risk. He did not add that it assumes dose density is uniform. “There are many kinds of radiation”, he says, but he does not mention how they differ. In fact, external sources like cosmic rays and x-rays distribute their energy evenly, like the sun; others, notably alpha-emitters like uranium, are extremely uneven in the way they irradiate body tissue once they have been inhaled or swallowed.”

Evacuation zone widened beyond 20km from Fukushima nuclear plant – April 22, Kyodo

Chernobyl: distorted reality and unanswered questions – April 21, 2011, Greenpeace Blog

  • “We have just returned after completing an important mission in Ukraine – taking around 70 journalists from 18 countries with us to Chernobyl, nearly 25 years after the nuclear catastrophe. It was one of the largest media trips Greenpeace has organized. These seasoned journalists asked critical and insightful questions, none of them easily moved.
  • But many of them were deeply disturbed by what they saw and heard – often by the mundane details that were mentioned matter-of-factly by the interviewees.”

Scenes from the Fukushima Exclusion Zone – Good Blog

  • “In the wake of the earthquake and tsunami in Japan, photographer Donald Weber set out for the “exclusion zone” around the Fukushima nuclear reactors. Residents of this buffer area were forced to evacuate immediately after the tsunami struck, leaving an eerie abandoned urban landscape. Besides the military, Weber and his partner were, he believes, “the only other people to go to the exclusion zone and actually see what the reality is there.””

Tokyo Takes Over PR From Plant Operator – Wall Street Journal

  • “Tepco’s briefings have at times turned confrontational. “You guys lack accountability,” some reporters have shouted, eliciting apologies from Tepco spokesmen. “Who is the person overseeing this operation?” asked one reporter at a briefing earlier this month on Tepco’s planned discharge of lightly radioactive water into the ocean. “Why can he not come here? Tell me his name. Who is it? Go up and find out right now. Go right now. Go right now.””

FEATURE: Judges tend to side with utilities in atomic power plant cases – April 25, Kyodo

  • The risk of an earthquake causing critical damage to a nuclear power plant has been the subject of lawsuits filed by local residents in various parts of Japan over the years, but to date none of these legal actions has led to operations at a plant being suspended.
  • The courts have been inclined to accept arguments that nuclear power plants are safe, citing the highly technical nature of atomic power generation. In light of the ongoing crisis at Fukushima, however, critics say the judges should be held accountable for abandoning their role to properly scrutinize such cases.

A 100-Year Plan for Nuclear Waste – Technology Review

Celebrate Freedom Day

I started to work in Africa in the mid 1980s. Since I had been admitted to a graduate program that was heavily involved with work in Kenya, it would make sense that I’d work there, but I was well aware of the fact that there would be no work at Koobi Fora until the Koobi Fora monograph was done, since those in charge of that research felt a responsibility to get what they had done published before collecting more data from the field. I had the opportunity to work in South Africa as well, and there were good reasons for me to do that, but there was one very large reason not to: Apartheid. I observed the boycott even to the extent at sneering at Paul Simon, I certainly would not work in a country with the most racist regime in modern history. Fortunately, Zaire was there for me, and for many reasons it was a better place to do research for me than either Kenya or South Africa. So I did.

Steve Jobs: “Android tracks you, Apple does not.”

According to Steve Jobs, Apple’s iPhone and/or Apple corporation (the distinction is important but often muddled in this conversation) does not track its users’ geographical location, but Android (which is neither a phone nor a company, but a system … another important yet muddled distinction) does.

What Does IQ Really Measure?

Kids who score higher on IQ tests will, on average, go on to do better in conventional measures of success in life: academic achievement, economic success, even greater health, and longevity. Is that because they are more intelligent? Not necessarily. New research concludes that IQ scores are partly a measure of how motivated a child is to do well on the test. And harnessing that motivation might be as important to later success as so-called native intelligence.

Wii to be replaced in 2012; Preview expected in early June 2010

I’ve hardly ever played video games, and Julia, growing up, never did either. Then a couple of years ago we got a Wii and now we play it regularly but responsibly. Amanda joins us now and then.

After the filing of our 1040s, we realized we could afford to buy a new TV to replace our old energy-hogging tube model, so we did. Now we will be able to see what we are doing when using the Wii. As an indicator of how much we are NOT addicted to game play, I’ll note that other than testing that the connection works, We’ve not used it since installing the TV on Friday.

The Wii is great, but it is oddly quirky in its design. A key feature of the Wii is the Wii remote, an oblong object with numerous buttons and a wrist strap. There is a gel-substance cover that protects the remote, but that the user must fit over it, that must be removed to change batteries, or to add an “extra sensitivity” device.

The remote senses its own movement, but not sensitively enough for some games, so those games require the addition of an extra sensitivity device which mus be added to the oblong remote.

The extra sensitivity device must be removed to get the remote into the charger one normally would keep it in while not in use. The gel cover must be partly removed and the safety strap must be pulled awkwardly to one side, in order to get the remote into its charging cradle. Its like having sex while wearing an elaborate Halloween costume. Or maybe its like this. In any event, the safety strap, extra sensitivity, gel cover and ability to charge all seem to have been afterthoughts of each other.

But when the thing is all put together right, its fun and cool. People who use other gaming systems may disagree, but what do they know?1

Just the other day Julia expressed this concern: “I wonder when the next version of the Wii is going to come out?” … And, Nintendo responded with this:

To whom it may concern:

Re: Wii’s successor system

Nintendo Co., Ltd. has decided to launch in 2012 a system to succeed Wii, which the company has sold 86.01 million units on a consolidated shipment basis between its launch in 2006 and the end of March 2011.

We will show a playable model of the new system and announce more specifications at the E3 Expo, which will be held June 7-9, 2011, in Los Angeles.

Sales of this new system have not been included in the financial forecasts announced today for the fiscal term ending March 2012.


Tiere is a claim that it will spit cappuccino into your face. How cool is that?

By the way, if you need a new TV here’s how to get one.

1Probably a lot more than I do, because I’ve never used them and don’t even know what they are called or what they do.

Explosion/Meltdown at Chernobyl Nuclear Power Plant

The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in the Ukrainian SSR (now Ukraine). It is considered the worst nuclear power plant accident in history, and it is the only one classified as a level 7 event on the International Nuclear Event Scale.


But it’s OK, because all that really happened is a few dozen people died in the explosion and fire, several thousand children had their thyroids cut out, and farmers across much of eastern Europe got an extended vacation.

Accidental v. Intentional, Fatal v. Non-Fatal, Gunshots, 2000-2007 in the USA

From 2000 through 2007, inclusively, approximately 780 thousand people in the United States took a bullet. Most of them were wounded by another person in an act of violence. A fairly large number were wounded by accident, killed by a bad guy, or killed themselves. A small number died in a shooting accident, tried to kill themselves but messed up, or were wounded or shot by a cop. Here’s the data culled form the CDC databases on injuries and deaths in the US, in crude rate per 100,000:
