Nuclear Experiments?That's why they are so useless (thanks to supercomputers and fermi)

The President of the United States, Donald Trump, announced and ordered the return of atomic tests, which the US abandoned in 1992. They should be concluded "without atomic explosions".But is it possible?Is this a misunderstanding or an oxymoron?In fact, it can be done thanks to the computing power of quintillion operations per second and the Oak Ridge location where the Italian physicist worked.

Donald Trump: "Even Russia and China do tests, but they don't talk about it. We're an open society, we're different, and we'll talk about it."Let's talk about it.

The last nuclear test of the United States is not so far back in time: it corresponds to 1992, in the Naada desert, in 1992.The Cold War was already over.The Berlin Wall came down.And so did the Soviet Union.Boris Yeltsin already ruled the Russian Federation.

On the other hand, France conducted 179 nuclear tests between 1966 and 1996, 138 of them at a volcano located on the ill-fated Mururoa Atoll, a former paradise on earth in French Polynesia (the same Polynesia we all associate with Paul Gauguin).The remaining experiments were performed directly in the atmosphere.

During these thirty years alone, under Mururoi, it is estimated that France exploded the equivalent of about 200 Hiroshima-like bombs.Remember that nuclear bombs are the most concrete demonstration of power expressed by the most famous and least understood scientific formula in the world: energy equals mass times the square of the speed of light.Copyright: Albert Einstein.Given that c, the speed of light, is 300,000 km per second, and its squared is 300 thousand times 300 thousand, we conclude that mass is energy, but since c squared is a very large number, you can get a lot of energy from even very small masses.In fact, it is estimated that the Hiroshima bomb contained only one gram of fissile material.Probably the worst casualty ratio in human history.

The numbers matter and may explain the apparent oxymoron of the "no explosion" test.To understand this, we must have access to a very specific place located in Oak Ridge, Tennessee, United States, with 34 thousand inhabitants, with a very high average IQ.Many scientists work there.The interesting history of this citadel (from the name: oak ridge) can be understood by learning the year of its foundation.1942...

During the Second World War, the demand for energy came from this desolate place.It was also one of the sites of Uranium enrichment, a project under Enrico Fermi, known as Codex Agricola.Today we know that the Manhattan project has allowed us to accelerate the use of computers in research for scientific, even military purposes (the so-called dual "two technologies" of two technologies. Fermi himself was one of the supporters of these things. But the point of this theory was von Neumann, so much so that even today it is the basic structure of computers.

If we go and check what is happening in Oak Ridge today we find that the Oak Ridge National Laboratory is still active, which is still under the US Department of Energy.Inside the laboratory, the most powerful supercomputers in the world find their home: Jaguar which was number one in 2010, when it was launched. Titan also got the scepter here in 2012. Then in 2018 came the time of the summit. Finally Frontier's time, number 1 in 2022. To understand its name we have to recall a phrase by Vannevar Bush, head of American research and development during the Second World War andtherefore at the beginning of the Manhattan Project (formerly of MIT and expert in analog computers, an experimental branch of computational machines of the 1920s that took inspiration from Babbage's famous machine of 1840: for those interested, the Genie Podcast on the subject of Invisible).

Bush wrote: "It has been a fundamental policy of the United States to encourage the opening of new frontiers."He opened sailing ships and lands for pioneers.And when these boundaries often disappear, the boundaries of science remain."

Frontier is going through one quirillion operations per second (10 to the eight power: a billion billion).

What is the need for all this computing capacity in a laboratory that works for the Department of Energy?Correctly simulate all reactions of a virtual explosion, but completely reliable in terms of data analysis.The computer is able to simulate the entire experiment, calculating all the physical and chemical consequences of the test.That's why US Minister Wright talked about unnecessary explosions.it would be useless.Of course, testing on a supercomputer is less impressive.And it's less scary.Maybe we can play about it?

PS, China refuses to do the tests (but has supercomputers).
