Comments - Teller and the Two Lies - by Jack Devanney

Many have forgotten that we are standing on the shoulders of legends such as Teller and Oppenheimer.

Recently the Oppenheimer grandson rallied in favor of nuclear:

"New Manhattan Project for Carbon-free Energy"

Also note the energy density of nuclear vs other energy containers:

Li abttery : 0.5 MJ/kg

Diesel/gas : 46 MJ/kg

Nuclear, U-235, E=mc^2 : 79,390,000 MJ/kg

Android’s emergency call shortcut is flooding dispatchers with false calls | Ars Technica

Police forces in the UK are seeing a "record number" of false calls to 999, the UK's emergency services number, and the culprit is apparently Android. As the BBC reports, Android 12 added an easy-access feature for emergency services: just press the power button five times, and your phone will dial emergency services for you. That's apparently pretty easy to do accidentally when a phone is sitting in your pocket, or if you have a wonky power button, resulting in a surge of totally silent accidental calls to emergency dispatch.

Teller like most of us was a bundle of contradictions. He was certainly aware that a major release from an NPP would provide ammunition to those who wanted to shut down weapon testing, which he thought was absolutely necessary to keep up with the Soviets.

Here's a mind-blowing fact. Teller, Leo Szilard, John vonNeumann and Eugene Wigner, a sizable proportion of the American WWII brain trust, all graduated from the same Budapest high school within a few years of each other. That must have been a hell of a high school.

No wonder Teller wanted to upgrade American education.

Jack - Didn't some of the other members of the Manhattan project refer to the Hungarians as "The Martians", implying that their skills were out of this world?

The story is that the Manhattan Project greats were having lunch at the University of Chicago. Fermi is speculating about earth being visited by a master race, possibly from Mars. Szilard chimes in "They are already here, disguised as Hungarians". He had a point, but apparently the Martians used this one high school as a staging point.

In 1959, the AEC and the nuclear power establishment made a momentous policy change. They abandoned the concept of a tolerance dose rate below which harm is undetectable, and adopted the Linear No Threshold hypothesis, which claims that harm is proportional to cumulative dose, regardless of how rapidly or how slowly that dose is received. In other words, radiation harm is unrepairable. It just builds up. The tolerance dose rate model assumes our bodies can repair radiation damage. As a result, harm does not build up as long as we stay below the tolerance dose rate, which up to 1950 was 1 mSv/d.

What's really perplexing about this foundational transformation is that it apparently was done with no discussion. There seems to be no official decision from the AEC. No meeting minutes. No dueling memos. The official history of the AEC, Mazuzan and Walker, 511 tedious pages covering the period 1946-1962, makes no mention of the decision.1
The book makes no mention of LNT at all.

NJ Man Bought a United Lifetime Pass for $290k, Has Flown 23 Million Miles

In 1990, Tom Stuker bought a United Airlines lifetime pass. He has since flown 23 million miles.

Stuker has redeemed countless numbers of miles and at one point didn't sleep in a bed for 12 days.

Stuker told The Washington Post that the pass was the "best investment of my life." //

Stuker — a car dealership consultant from New Jersey — has flown 23 million miles, which, according to The Washington Post, is more miles than any individual in history.
