SUnknownThe True Story of the Demon Core

Thu, Nov 26, 2020

Following the dramatic 'demonstration' of implosion devices to create a supercritical nuclear core and subsequent explosions physicists continued looking for alternative ways to reach criticality. One effective approach was to reflect neutrons released during fission back on the nuclear core. But lab technique was sloppy and two prominent scientists received massive does of radiation after their slips and died within days of exposure.

SUnknownThe Castle Bravo Disaster - A "Second Hiroshima"

Thu, Jan 21, 2021

Castle Bravo was the world's first fusion bomb test. It was powered by lithium-6 deuteride but it also included a larger amount of Lithium-7 deuteride which was expected to be inert. Unexpectedly, the Lithium-7 fissioned into tritium which increased the power of the explosion by a factor of three. It also spread radioactive fallout and radiation sickness over a wide area creating a global outcry.

Or can we? Care to give it a try?

SUnknownOne Weird Math Trick to Estimate Anything

Fri, May 28, 2021

Enrico Fermi had a talent for estimating values. Klye shares his trick; dimensional analysis. Instead of trying to estimate a big unknown directly, break it down into smaller pieces that you already know or that your can can estimate fairly accurately. Line the numbers up in big long multiplication equation so all the units in the numerator and denominator cancel out except the two you're interested in. Voila. A pretty good estimate.
