Daring Sort Books, $30
The US is on a mission to modernize its ageing nuclear weapons stockpile. And physicists have emotions about it — and the way forward for nuclear weapons extra broadly.
In Countdown, science author Sarah Scoles dredges up all of the feels in interviews with physicists on the nationwide laboratories devoted to sustaining the U.S. nuclear stockpile and with researchers, activists and others who orbit that lab system. The researchers grapple with the legacy of their subject’s most notorious invention and their roles as stewards of the planet’s most damaging weapons (SN: 8/6/20).
To work on nuclear weapons, Scoles’ conversations reveal, is to embrace seemingly contradictory concepts. The weapons promote peace by deterring international locations from attacking one another, however the weapons additionally make potential the destruction of civilization. The researchers see their work — on quite a lot of subjects, from laptop simulations of nuclear weapons to nonproliferation analysis — as crucial and even discover magnificence in it, however some additionally dream of a world with out these bombs.
The US has not examined nuclear weapons for the reason that Nineteen Nineties, when it signed the Complete Nuclear-Check-Ban Treaty (SN: 4/8/21). To keep up confidence in its roughly 3,700 nuclear weapons, the nation goals to exchange the steadily degrading nuclear materials at their hearts. These bowling ball–sized pits are hole spheres of plutonium that kick off the nuclear explosion when a bomb detonates. At present, the USA is caught with its ageing pits, however by 2030, the plan is to supply 80 pits per 12 months.
But some activists oppose the pit manufacturing and different modernization efforts — the main points of that are categorized and thus unknown to the general public. Whereas proponents see updating the weapons as important to shore up the deterrent, others assume the deterrent is efficient as is and fear modernizing may kick off a harmful arms race.
Countdown additionally delves into the historical past and tradition of the nationwide labs targeted on nuclear work. Whereas a few of it looks as if inside baseball — this or that administration change — there may be severe tea spilled. One scientist says Los Alamos “is in a Fifties bubble,” lamenting the lab’s seeming deal with the “cult of genius” — the outdated mannequin by which a lone researcher transforms a subject. And Scoles recounts drama from many years prior, of workers at Los Alamos Nationwide Laboratory in New Mexico and Lawrence Livermore Nationwide Laboratory in California rebelling in opposition to administration one of the best ways they knew how: offended weblog posts and no less than one snarky limerick (SN: 6/6/22).
With witty consideration to element, Scoles inserts moments of levity, mentioning the small absurdities surrounding this in any other case heavy matter. (She meets a scientist at Los Alamos’ Scorching Rocks Java Cafe, “a spot whose title suggests the Nineteen Nineties got here up with it.”) And the scientists’ ardour for his or her subject shines by, like the sensation of exhilaration that comes with taming plasma, a feral state of matter consisting of electrically charged particles.
At instances the e-book leaves the reader craving extra scientific particulars, maybe unavoidable when coping with a categorized topic. However some subjects are glossed over greater than crucial. The dialogue of quantum computing — a expertise that may finally be helpful for simulating nuclear weapons — is so abbreviated as to be complicated.
All through the e-book, Scoles highlights the deep connections that run between primary scientific analysis and nuclear purposes. The circumstances in an atomic bomb are just like these elsewhere within the universe, similar to in exploding stars. That implies that even physicists who got down to reveal primary options of the universe would possibly inadvertently advance information about nuclear weapons. Prefer it or not, physics and nuclear weapons are inseparable.
The researchers Scoles profiles hope that, by understanding nuclear weapons higher, we’d defend ourselves from them. One analysis staff goals to enhance the detection of nuclear blasts, making it simpler to confirm that different international locations aren’t setting them off. However such information may additionally educate a authorities tips on how to conceal its personal checks from prying eyes. Like a lot else in nuclear weapons analysis, there are two sides.
