Say hello to my little friend.
My new Brompton; hand-made in London, like my summer 2002 bout of alcoholism. It being my first time mounting a bicycle in 16 years, I was a little nervous and thought I might require training wheels but it turns out that the old saw is true.
I rode 12 miles Saturday after bringing it home, 10 miles Sunday. I'm giving my ass a rest for a couple days but my goal is to ride to CoSA's office (24.2 miles round trip) by the end of the week.

Nuclear Testing from 1945-1998
A total of 2053 detonations:
United States 1032
U.S.S.R. 715
France 210
United Kingdom 45
China 45
India 4
Pakistan 2
The world's first explosion of a nuclear device was the Trinity test in Jornada del Muerto's Tularosa Basin on July 16, 1945. The next two detonations were also the first and last time nuclear devices were used in military combat as weapons -- the attacks on Hiroshima and Nagasaki on August 6 and August 9, 1945. Of the ensuing tests conducted by the U.S., over 200 were detonated aboveground in the lower 48 states and in the Pacific Ocean between July 1946 and November 1962. Roughly half of these took place at The Nevada Test Site, a 3500 square-kilometer area located 100 kilometers northwest of Las Vegas, NV. More than 800 additional underground weapons tests were conducted from 1962 through September 1992. (source - Division of Radiation Control, Utah Dept. of Environmental Quality)
The U.S. is the only nation that has compensated victims exposed to radiation from nuclear testing.

More good information on Fukushima
Here are some relevant passages, including worst case scenarios and data on potassium iodide tablets:
"...Let me now talk about what would be a reasonable worst case scenario. If the Japanese fail to keep the reactors cool and fail to keep the pressure in the containment vessels at an appropriate level, you can get this, you know, the dramatic word “meltdown”. But what does that actually mean? What a meltdown involves is the basic reactor core melts, and as it melts, nuclear material will fall through to the floor of the container. There it will react with concrete and other materials … that is likely… remember this is the reasonable worst case, we don’t think anything worse is going to happen. In this reasonable worst case you get an explosion. You get some radioactive material going up to about 500 metres up into the air. Now, that’s really serious, but it’s serious again for the local area. It’s not serious for elsewhere even if you get a combination of that explosion it would only have nuclear material going in to the air up to about 500 metres. If you then couple that with the worst possible weather situation i.e. prevailing weather taking radioactive material in the direction of Greater Tokyo and you had maybe rainfall which would bring the radioactive material down do we have a problem? The answer is unequivocally no. Absolutely no issue. The problems are within 30 km of the reactor. And to give you a flavour for that, when Chernobyl had a massive fire at the graphite core, material was going up not just 500 metres but to 30,000 feet. It was lasting not for the odd hour or so but lasted months, and that was putting nuclear radioactive material up into the upper atmosphere for a very long period of time. But even in the case of Chernobyl, the exclusion zone that they had was about 30 kilometres. And in that exclusion zone, outside that, there is no evidence whatsoever to indicate people had problems from the radiation. The problems with Chernobyl were people were continuing to drink the water, continuing to eat vegetables and so on and that was where the problems came from. That’s not going to be the case here. So what I would really re-emphasise is that this is very problematic for the area and the immediate vicinity and one has to have concerns for the people working there. Beyond that 20 or 30 kilometres, it’s really not an issue for health.
...
[Q] Could you just explain why the worst case scenario here is much less than at Chernobyl?
[JB] Yeah, very much so. In Chernobyl, , first of all the top blew off the reactor and then the core of the reactor, the graphite which surrounds the core actually caught fire and burned for a very long time, so you had very, very, hot fire pushing all the material up in the normal sort of convection processes. Here, what will happen with the build up of pressure if the radioactive material interacted with the container floor and you would get a single explosion but it would not be a continued explosion. So that explosion would send material up to about 500 metres would be the sort of level we would expect. You know, it’s spurious accuracy, it might be 517 or 483 but that’s about it. And in terms of that, and couple that with weather, we still see absolutely no issue of material being taken at any critical level for human health beyond that 20 kilometres or so.
...
[Q] The next question, there’s a lot of concern in the community about the taking of iodine. At what point should iodine be taken and would you recommend people taking it proactively?
[Nick Kent, HPA Physician] Yes, I am. I think I’ll answer it in two ways. The ways you may get exposed to radio iodine are either you inhale volatile radio iodine and that will only happen very close to the nuclear power plant itself, and we certainly do recommend where people are close to a nuclear plant when an accident occurs that they should take stable iodine to block iodine uptake to the thyroid in those circumstances. But there’s nobody close to the nuclear plant and that’s not a means by which there will be exposure here, and therefore that’s not, you know that is not a reason to take iodine in the case of yourselves living in Tokyo. The second but most important way that people get exposed to radio iodine is that as the radio iodine settles into the environment, it gets incorporated into crops, it gets taken up into animals and it gets excreted into milk. And the problem in the case of Chernobyl which is where quite a number of cases of thyroid cancer were seen, it is now clear that the exposure pathway in the Russian Federation and Ukraine was ingestion of contaminated food, particularly milk. Now, we do not envisage the food chain as being an issue for you to take it up, and in any case, to use iodine to protect against the food chain would take long term administration of iodine, which would not be appropriate for other reasons, like the effects that would be on the thyroid. So I’ll just summarise. You’re not close to the plant so you’re not at an inhalation risk which is the principle use for iodine, and you we do not envisage you getting any radio iodine exposure through the food chain so again you know, no exposure therefore no need to use iodine as a countermeasure. Thank you."

Nuclear/Unclear
1. Nuclear Overreactors in Slate, by William Saletan. It is pithy and enlightening in its comparison of nuclear energy production to fossil fuels: "...fossil fuel is more dangerous. The sole fatal nuclear power accident of the last 40 years, Chernobyl, directly killed 31 people. By comparison, Switzerland's Paul Scherrer Institute calculates that from 1969 to 2000, more than 20,000 people died in severe accidents in the oil supply chain. More than 15,000 people died in severe accidents in the coal supply chain—11,000 in China alone. The rate of direct fatalities per unit of energy production is 18 times worse for oil than it is for nuclear power."
2. Japan's nuclear reactor overreaction by the Bad Astronomer, Phil Plait. As always, Phil nails it; like Saletan, he keeps it short and to the point, and brings in some more facts that I wasn't aware of, like "coal plants release more radiation than nuclear plants by a long shot...not to mention the disastrous environmental impact of burning it. How safe is that? Yet we use far more energy from coal than from nuclear plants."
3. The best by far is this discussion by Dr. Joseph Oehmen, originally posted on the blog of an English teacher in Japan, but now hosted and maintained by the MIT Dept. of Nuclear Science and Engineering. This is a very comprehensive explication of nuclear reactions, nuclear reactors in general, what has specifically happened thus far at Fukushima, and what will most likely happen. The educational value of this piece is priceless, and though it's longer than the others, it reads like a thriller.
The absolute worst thing I've seen in the last three days is this Youtube clip of a cretinous American Christian, deliriously thanking the god of the Bible for shaking Japan at this start of the Lentil [sic] season, in an attempt to open the eyes of atheists everywhere.
Despite this young lady's enthusiasm for the death and destruction she believes she helped cause, intercessory prayer doesn't work, whether one is trying to hurt the victims or help them. If you would like to do the latter, please consider donating to the Center For Inquiry's S.H.A.R.E. program. 100% of your donation, with no operating costs retained, will be given to Doctors Without Borders, a secular organization that already has teams assisting the government-led response in Japan.

Historic Core Valediction
I'll soon be moving out of the historic core/old bank district -- my home for the last four years -- so I took a couple evening walks around the block with camera in hand last week. Each photo is geotagged in Flickr; clicking any one will bring you to that photo's page to view location, specific architectural information, and camera data.

iPhone 4

Returned to Tom's a little while ago, trying out FaceTime now. We arrived at Glendale Galleria at about 06:30, but there were at least 500 people ahead of us in the parking garage reservation queue, which snaked around like those stacked lines you see at amusement park rides. There was a separate line of at least 100 people who hadn't made a reservation at the far end. The Apple employees handled everything quite well -- coming out and distributing water, coffee, danishes and donuts. At 07:00 the first people were let in to the mall, 25 at a time, in pulses about 12-13 minutes apart. For every 50 people in the reservation queue, one person from the non-reservation queue was taken to join that group. The non-reservationist girl who came up to join us had been waiting since 22:00 last night; she was the 7th person in the non-reservation line. Once inside the mall there were several more (shorter) lines to stand in before reaching the store. The Apple Store was processing about 150 people per hour. We were out of the store, activated iP4 in hand with contacts transferred, at 10:45.
