Countdown

Daring Kind Books, $30
The USA is on a mission to modernize its growing older 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 discipline’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 nations from attacking one another, however the weapons additionally make doable the destruction of civilization. The researchers see their work — on a wide range of subjects, from pc simulations of nuclear weapons to nonproliferation analysis — as vital and even discover magnificence in it, however some additionally dream of a world with out these bombs.
The USA has not examined nuclear weapons for the reason that Nineties, when it signed the Complete Nuclear-Check-Ban Treaty (SN: 4/8/21). To take care of 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 the moment, the US is caught with its growing older pits, however by 2030, the plan is to provide 80 pits per yr.
But some activists oppose the pit manufacturing and different modernization efforts — the small print of that are categorised 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’s critical 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scientist says Los Alamos “is in a Fifties bubble,” lamenting the lab’s seeming deal with the “cult of genius” — the outdated mannequin by which a lone researcher transforms a discipline. And Scoles recounts drama from a long time prior, of workers at Los Alamos Nationwide Laboratory in New Mexico and Lawrence Livermore Nationwide Laboratory in California rebelling towards administration the easiest way they knew how: indignant 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’ Sizzling Rocks Java Cafe, “a spot whose identify suggests the Nineties got here up with it.”) And the scientists’ ardour for his or her discipline shines by means of, like the sensation of exhilaration that comes with taming plasma, a feral state of matter consisting of electrically charged particles.
At occasions the e-book leaves the reader craving extra scientific particulars, maybe unavoidable when coping with a categorised topic. However some subjects are glossed over greater than vital. The dialogue of quantum computing — a know-how 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 fundamental scientific analysis and nuclear functions. The situations in an atomic bomb are just like these elsewhere within the universe, resembling in exploding stars. That implies that even physicists who got down to reveal fundamental options of the universe may inadvertently advance data 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 shield ourselves from them. One analysis workforce goals to enhance the detection of nuclear blasts, making it simpler to confirm that different nations aren’t setting them off. However such data may additionally educate a authorities easy methods to disguise its personal checks from prying eyes. Like a lot else in nuclear weapons analysis, there are two sides.
