hi

Nice direwolf Sansa, and way to look all regal and stuff, life must be pretty good; you don’t know it yet but things don’t go so well for you.

Fuck yes I’m watching Game of Thrones and its awesome. But its bittersweet because it reminds me that RR Martin has time to co-develop a show but not finish a book in over five years. 

Tickling the Dragons Tail

This picture shows a recreation of how the critically of a core of plutonium was often tested back in the ’40s. What we are seeing is a beryllium shield being lowered over a sphere (unseen) of plutonium; using a common screwdriver as a lever. As the shield is lowered more neutrons are reflected back onto the core and its level of excitement increases. The name arises from the extreme danger, if the shield was closed accidentally, the mass would become supercritical releasing a huge wave of neutron radiation.

In 1946 an unlucky scientist performing this experiment on a 6.2kg mass of plutonium (probably 238 or 239) had the shield slip and close:

Instantly there was a flash of blue light and a wave of heat across Slotin’s skin; the core had become supercritical, releasing a massive burst of neutron radiation. He quickly knocked the two halves apart, stopping the chain reaction and likely saving the lives of the other men in the laboratory. Slotin’s body positioning over the apparatus also shielded the others from much of the neutron radiation. He received a massively lethal dose in under a second and died 9 days later from acute radiation poisoning.

I find it amazing how blasé scientists were about the dangers of nuclear testing back in its early days. Ironically a previous scientist had been exposed to a lethal dose of radiation by the same core. This core was later detonated and found to produce a higher-than-expected yield due to its absorption of two life forces the excursions to criticality leading it to being named the Demon Core

…all you fuck-head Jersey Shore wannabes can go back to the suburbs, to spend the exorbitant amounts of cash you were going to use on bedazzled wifebeaters, on your illegitimate children instead.

Brilliant.
