The Real Mother of All Bombs, 46 Years Ago

vaporland writes "Tsar Bomba is the Western name for the RDS-220, the largest, most powerful weapon ever detonated. The bomb was tested on October 30, 1961, in an archipelago in the Arctic Sea. Developed by the Soviet Union, the bomb had a yield of about 50 megatons. Its detonation released energy equivalent to approximately 1% of the power output of the Sun for 39 nanoseconds of its detonation. The device was scaled down from its original design of 100 megatons to reduce the resulting nuclear fallout. The Tsar Bomba qualifies as the single most powerful device ever utilized throughout the history of humanity."

      I just finished reading "A Brief History of Rome" (free e-book from gutenberg.org). Throughout, the 19th-century author kept referring to "Barbarians" and "Civilization". I eventually figured out that the difference was literacy (the pen). The Romans inflicted both the pen, and Christianity on the world. The author seemed to think both were true gifts, but I noticed that the downfall of Rome started in earnest with Constantine, who converted them empire's faith, and that the dark-ages followed shortly after. Coincidence? I doubt it. Wikipedia has a great article on it. Just my own two-cents, but a corrupt society built on slavery and the spoils of war needed the old religion and an all-powerful emperor to survive. So... which is more powerful, the pen, or religion?

Later historians turned more to ideas of internal factors such as the increased tax burden on local elites and the Empire allowing barbarian auxiliaries to settle within the empire's borders under their own leaders.

      I was an MIT undergrad when Ronald Reagan came into office. The Reagan administration was a boon to certain types of research, and a bust for others. There was an enormous shift in emphasis towards research that could be weaponized.

      I remember a scientist who joined the project I was working on. He had headed a small lab elsewhere at MIT as a principal investigator, but he signed on to our project as an engineer because research money had dried up. He brought with him this odd stainless steel apparatus that looked like a mutated, high tech water main. We were using it as small vacuum tank. I asked him what the thing was built to do, and he told me that it was a new kind of electron microscope he had invented that could make images showing the distribution of the different kinds of atomic nuclei in the thing being imaged.

      "Wow, that's very interesting," I said.

      "It is," he replied, "but it was funded on an ONR grant, and they're not funding that kind of research any more. Back in the old days," he went on, "I'd have told them it was a death ray. It's all those damned ROTC engineering grads," he sighed. "About the only way you could kill somebody with this is to drop it on him from a high place. Those guys aren't physicists, but they know a death ray when they see one. All they want to talk about is deaths per dollar."

      The deaths per dollar metric fascinated me. Later I brought it up with some of my friends back at the dorm, and we kicked around the question of how various methods of manslaughter stacked up. The idea of blowing up the famous "Corita" LNG tanks near Boston was popular, until we fetched some Chem E majors who told us about the eight hundred reasons that you couldn't kill more than a handful of people that way.

      Finally, I hit upon an unbeatable method when it comes to deaths per dollar. Go to a construction site, and root through the dumpster until you get a nice section of 2x4 about five feet long. Then walk down the street and beat everybody you meet to death with it.

      "But," they protested, "that's assuming that your time is free."

It was quickly abandoned when ICBM targeting became accurate enough to ensure you could level whatever target you want to strike. And MIRVs offer much more destruction per ton carried.

    I repeat: 39ns is just the period of time that the power level peaked for. They calculated that the amplitude of the power peak itself, was equivalent to 1% the power output of the sun.

    We don't care about how long the peak lasted for, the 39ns, unless you start integrating power over time as you just did, in which case you're comparing a quantity of energy, rather than a rate of energy output.
