Visualized: How Nuclear Weapons Work
In 1945, the world’s first-ever nuclear weapon was detonated at the Trinity test site in New Mexico, United States, marking the beginning of the Atomic Age.
Since then, the global nuclear stockpile has multiplied, and when geopolitical tensions rise, the idea of a nuclear apocalypse understandably causes widespread concern.
But despite their catastrophically large effects, the science of how nuclear weapons work is atomically small.
The Atomic Science of Nuclear Weapons
All matter is composed of atoms, which host different combinations of three particles—protons, electrons, and neutrons. Nuclear weapons work by capitalizing on the interactions of protons and neutrons to create an explosive chain reaction.
At the center of every atom is a core called the nucleus, which is composed of closely-bound protons and neutrons. While the number of protons is unique to each element in the periodic table, the number of neutrons can vary. As a result, there are multiple “species” of some elements, known as isotopes.
For example, here are some isotopes of uranium:
- Uranium-238: 92 protons, 146 neutrons
- Uranium-235: 92 protons, 143 neutrons
- Uranium-234: 92 protons, 142 neutrons
These isotopes can be stable or unstable. Stable isotopes have a relatively static or unchanging number of neutrons. But when a chemical element has too many neutrons, it becomes unstable or fissile.
When fissile isotopes attempt to become stable, they shed excess neutrons and energy. This energy is where nuclear weapons get their explosivity from.
There are two types of nuclear weapons:
- Atomic Bombs: These rely on a domino effect of multiple fission reactions to produce an explosion, using either uranium or plutonium.
- Hydrogen Bombs: These rely on a combination of fission and fusion using uranium or plutonium, with the help of lighter elements like the isotopes of hydrogen.
So, what exactly is the difference between fission and fusion reactions?
Splitting Atoms: Nuclear Fission
Nuclear fission—the process used by nuclear reactors—produces large amounts of energy by breaking apart a heavier unstable atom into two smaller atoms, starting a nuclear chain reaction.
When a neutron is fired into the nucleus of a fissile atom like uranium-235, the uranium atom splits into two smaller atoms known as “fissile fragments” in addition to more neutrons and energy. These excess neutrons can then start a self-sustaining chain reaction by hitting the nuclei of other uranium-235 atoms, resulting in an atomic explosion.
Atomic bombs use nuclear fission, though it’s important to note that a fission chain reaction requires a particular amount of a fissile material like uranium-235, known as the supercritical mass.
Merging Atoms: Nuclear Fusion
Hydrogen bombs use a combination of fission and fusion, with nuclear fusion amplifying a fission reaction to produce a much more powerful explosion than atomic bombs.
Fusion is essentially the opposite of fission—instead of splitting a heavier atom into smaller atoms, it works by putting together two atoms to form a third unstable atom. It’s also the same process that fuels the Sun.
Nuclear fusion mainly relies on isotopes of lighter elements, like the two isotopes of hydrogen—deuterium and tritium. When subjected to intense heat and pressure, these two atoms fuse together to form an extremely unstable helium isotope, which releases energy and neutrons.
The released neutrons then fuel the fission reactions of heavier atoms like uranium-235, creating an explosive chain reaction.
How Atomic and Hydrogen Bombs Compare
Just how powerful are hydrogen bombs, and how do they compare to atomic bombs?
|Bomb||Type||Energy produced (kilotons of TNT)|
|Little Boy 🇺🇸||Atomic||15kt|
|Fat Man 🇺🇸||Atomic||21kt|
|Castle Bravo 🇺🇸||Hydrogen||15,000kt|
|Tsar Bomba 🇷🇺||Hydrogen||51,000kt|
The bombs Little Boy and Fat Man were used in the atomic bombings of Hiroshima and Nagasaki in 1945, bringing a destructive end to World War II. The scale of these bombings was, at the time, unparalleled. But comparing these to hydrogen bombs shows just how powerful nuclear weapons have become.
Castle Bravo was the codename for the United States’ largest-ever nuclear weapon test, a hydrogen bomb that produced a yield of 15,000 kilotons—making it 1,000 times more powerful than Little Boy. What’s more, radioactive traces from the explosion, which took place on the Marshall Islands near Fiji, were found in Australia, India, Japan, U.S., and Europe.
Seven years later, the Soviet Union tested Tsar Bomba in 1961, the world’s most powerful nuclear weapon. The explosion produced 51,000 kilotons of explosive energy, with a destructive radius of roughly 60km.
Given how damaging a single nuke can be, it’s difficult to imagine the outcome of an actual nuclear conflict without fear of total annihilation, especially with the world’s nuclear arsenal sitting at over 13,000 warheads.
Which Populations Feel Their Country is on the Wrong Track?
New polling data shows that, in many parts of the world, people feel that their countries are on a downward trajectory.
Which Populations Feel Their Country is on the Wrong Track?
Plato once used the allegory of a Ship of Fools to push for his vision of a wise philosopher-king as the ideal pilot for a ship of state.
Looking at the most recent numbers from Morning Consult Political Intelligence’s Projections of Country Trajectories, you would be forgiven for thinking that a great many people believe that their ship of state is piloted by fools.
With the impact of the pandemic, rising inflation, and growing geopolitical instability, it’s probably not surprising that most respondents feel their countries are on the wrong track; India and Switzerland were notable exceptions.
Below are some of the stand-out stories that we found digging through the data.
Midterm elections have rarely been kind to the incumbent party in U.S. politics and the cost of living crisis, an unpopular president, and the aftermath of the global pandemic pointed towards an electoral bloodbath. This year’s election was also expected to set a new spending record, with over $9 billion raised.
Even so, despite 72% of respondents thinking that the country is on the wrong track, the governing Democrats have defied expectations and posted a historic performance during the November 8, 2022, midterm elections. To put this into context, in a president’s first term, there have been three previous instances (since 1922) of the incumbent’s party gaining (or not losing) Senate seats and losing fewer than 10 seats in the House.
Also worth noting is the large spike in negative sentiment in January 2021, following the U.S. Capitol attack, followed by the convergence of negative and positive sentiments as the peaceful transition of power became more assured.
Horace, in Odes 1.14, describes a ship of state that is flailing at sea that eventually rights itself, claiming towards the end of the poem that “it’s my longing and no light love you carry.”
Something like that may be happening in Brazil following the loss of the often turbulent, COVID-19-denying President Jair Bolsonaro to political rival Luiz Inácio Lula da Silva in an Oct. 20, 2022, election runoff.
However, with respondents evenly split on where the country is going and the presidential election results being so close (50.9% vs. 49.1%), Lula will have his hands full governing a divided country.
While sentiment was overwhelmingly negative in almost every country tracked in this survey, India stood out as an outlier. India has consistently maintained a positive sentiment of between 60% and 80%, which is something only Switzerland comes close to.
The only blip was a brief period during the spring of 2021. This coincided with a deadly second wave of COVID-19 infections in the country, on top of country-wide protests against the Narendra Modi government’s deeply unpopular farm bill.
The data here covers the three most recent UK Prime Ministers: Boris Johnson, Liz Truss, and now Rishi Sunak, the first South Asian to hold the post.
In January 2020, Johnson had just won a Tory majority and succeeded in “Getting Brexit Done.” Political scandals and the government’s pandemic response pushed the trendline down. It only recovered briefly in the spring of 2021, following Russia’s invasion of the Donbas region of Ukraine, which Johnson was widely seen as handling well. A personal visit to Kyiv on April 9, 2022, helped cement this.
Then followed Prime Minister Liz Truss’ disastrous mini-budget of Sept. 23, 2022, which saw the pound fall to the lowest-ever level against the dollar and the Bank of England intervene in the bond markets. The ascension of Rishi Sunak to No. 10 Downing Street has only just begun to turn around the low of 89% negative sentiment reported on Oct 23-25, 2022.
To quote the BBC comedy series, Yes, Minister, in another context, “the ship of state is the only ship that leaks from the top.”
