Edward Tellella, another physicist, had naughty calculation that there's a nonzero chance that detonating the bomb would ignite the entire atmosphere of Earth, killing not just all humans, but every single shred of life. By that time, the US also knew that the Nazis were no longer capable of making the bomb nor even pursuing their own project anymore. They still went ahead and took the risk.

we're playing with levers and tools that are so powerful.

Trump pledged as a presidential candidate to keep America out of “stupid endless wars.” But he also vowed to prevent the Islamic Republic from obtaining a nuclear weapon.

But neither Defense Secretary Pete Hegseth nor Gen. Dan Caine, the chairman of the Joint Chiefs of Staff, could immediately say whether Iran still retained the ability to make a nuclear weapon. Mr. Hegseth repeated President Trump’s assertion from the previous night that the nuclear sites had been “obliterated.” General Caine did not.

Meanwhile, nuclear energy is being touted as a solution, but it is largely a dangerous distraction. The long timelines of Small Modular Reactors and safety risks of restarting decommissioned nuclear plants, as exemplified by Microsoft’s controversial plan to reopen the Three Mile Island site, further undermine the credibility of this approach. Without addressing the escalating energy demands of AI and their contribution to the climate crisis, the promise of AI as a “climate solution” is pure fiction.

The fossil fuelindustry is a significant contributor to the Big Green organizations, and many of theseorganizations are financially invested in renewables and fossil fuels, so they do not want tosee nuclear power as a competitor.

third thing okay um and the fourth thing soft power within the United

Significantly, that represents 7.3 TWh of annual clean electricity output that currently does not exist on the US powergrid. Compare that to the annual output of the nation’s largest utility-scale solar plant, Solar Star in California, that generates about 1.6 TWh per year from 747 MW of capacity.

The solution, and the reason the idea of shell structure in nuclei is such a counter-intuitive notion, is both elegant and simple. Consider a single nucleon in a nucleus. Within this nuclear fluid we can consider the interactions of each of the nucleons with the one we have singled out. All of these nucleons move rather quickly through this fluid, leading to the fact that our nucleons only sees the average effects of the attraction of all the other ones. This leads to us replacing, to first approximation, this effect by an average nuclear potential, as sketched in Figure 4.1.1\PageIndex{1}. Figure 4.1.1\PageIndex{1}: A sketch of the averaging approximation Thus the idea is that the shell structure is caused by the average field of all the other nucleons, a very elegant but rather surprising notion!

The thermodynamic limitsexplored above, for instance, apply to anyenergy technology we care to imagine.

example is weaponry

Despite all the hand-waving, there are still no viable, scalable, truly renewable energy sources waiting in the wings

I think that we should be putting a high priority on developing the Next Generation nuclear 01:45:54 power uh but it's uh it's uh it's going to be a a tough job and as long as the as the special 01:46:05 interests are controlling our government uh we're not going to solve it

Sweden they decided oh we need to have 100% carbon free electricity they decided on a design they built 10 nuclear power plants and 01:21:11 they went in a decade to carbon free energy well Germany's been working for decades and they're not anywhere near

I proposed that we although the workshop and I we brought the best experts from the United 01:15:48 States and uh the top nuclear experts from China and and talked about ways that we could make the Next Generation nuclear power which would be 01:16:00 inherently safer than the old technology in the sense that it would shut down in case of uh emergencies and earthquake or whatever

it was the mothers that made all the difference he said it was mothers mobilizing around the world that stopped the testing of nuclear weapons in the atmosphere

i think it's more likely that 00:49:59 that we will think we will think that we this particular set of procedures ai procedures that we linked into our strategic nuclear weapons system uh will keep us safer but we haven't recognized that they're 00:50:12 unintended that there are consequences glitches in it that make it actually stupid and it mistakes the flock of geese for an incoming barrage of russian missiles and and you know unleashes everything in response 00:50:25 before we can intervene

They were national strategic programs. The strategic programs were aligned with nuclear weapons programs. The government picked and enforced a single design for all of the reactors. The reactors were GW-scale due to thermal efficiencies required for cost effectiveness. The government ran human resourcing. The programs ran for 20 or 30 years. They built dozens of nuclear reactors to maintain the teams and momentum and to share lessons learned.

After CNN’s reporting, Musk reversed course, tweeting “the hell with it … we’ll just keep funding Ukraine govt for free.”

“How am I in this war?” Musk asks Isaacson. “Starlink was not meant to be involved in wars. It was so people can watch Netflix and chill and get online for school and do good peaceful things, not drone strikes.”

As Ukrainian submarine drones strapped with explosives approached the Russian fleet, they “lost connectivity and washed ashore harmlessly,” Isaacson writes. Musk’s decision, which left Ukrainian officials begging him to turn the satellites back on, was driven by an acute fear that Russia would respond to a Ukrainian attack on Crimea with nuclear weapons

Neutron stars[edit] In neutron stars, neutron heavy nuclei are found as relativistic electrons penetrate the nuclei and produce inverse beta decay, wherein the electron combines with a proton in the nucleus to make a neutron and an electron-neutrino: p  +  e−  →  n  +  νe As more and more neutrons are created in nuclei the energy levels for neutrons get filled up to an energy level equal to the rest mass of a neutron. At this point any electron penetrating a nucleus will create a neutron, which will "drip" out of the nucleus. At this point we have:[citation needed] E F n = m n c 2 {\displaystyle E_{\text{F}}^{n}=m_{n}c^{2}\,} And from this point onwards the equation E F n = ( p F n ) 2 c 2 + m n 2 c 4 {\displaystyle E_{\text{F}}^{n}={\sqrt {\left(p_{\text{F}}^{n}\right)^{2}c^{2}+m_{n}^{2}c^{4}}}\,} applies, where pFn is the Fermi momentum of the neutron. As we go deeper into the neutron star the free neutron density increases, and as the Fermi momentum increases with increasing density, the Fermi energy increases, so that energy levels lower than the top level reach neutron drip and more and more neutrons drip out of nuclei so that we get nuclei in a neutron fluid. Eventually all the neutrons drip out of nuclei and we have reached the neutron fluid interior of the neutron star.

Koodankulam: What the Media Didn’t Tell Us

Pollin: Neither negative emissions technologies nor nuclear power can likely contribute significantly to building an alternative global clean energy infrastructure. Indeed, it is more likely that they will create still more severe problems. Let’s start with nuclear.

Russia has approximately 6,000 nuclear warheads – the largest stockpile of nuclear weapons in the world. In an interview on Saturday, Medvedev said Russia’s nuclear doctrine did not require an enemy state to use such weapons first.He said: “We have a special document on nuclear deterrence. This document clearly indicates the grounds on which the Russian Federation is entitled to use nuclear weapons. There are a few of them, let me remind them to you:“Number one is the situation, when Russia is struck by a nuclear missile. The second case is any use of other nuclear weapons against Russia or its allies.“The third is an attack on a critical infrastructure that will have paralysed our nuclear deterrent forces.“And the fourth case is when an act of aggression is committed against Russia and its allies, which jeopardised the existence of the country itself, even without the use of nuclear weapons, that is, with the use of conventional weapons.”Medvedev added that there was a “determination to defend the independence, sovereignty of our country, not to give anyone a reason to doubt even the slightest that we are ready to give a worthy response to any infringement on our country, on its independence”.

Erdogan said. “We are building the Akkuyu Nuclear Energy Plant with Russia.”

nuclear weapons are -- 00:22:50 in a way they also, until now, preserved the peace of the world. I belong to the school of thought that if it was not for nuclear weapons, we would have had the Third World War between the Soviet Union and the United States and NATO sometime in the 1950s or '60s. That nuclear weapons actually, until today, served a good function. 00:23:16 It's because of nuclear weapons that we did not have any more direct clashes between superpowers because it was obvious that this would be collective suicide. But the danger is still there, it's always there. If there is miscalculation, then the results could, of course, be existential, catastrophic.

+b (ORBIT) shows Buckminster Fuller’s Dymaxion Map of the earth built from multiple layers of white industrial sugar cubes and illuminated by the complete sequence of all nuclear explosions from 1945 until now. Using the cubes as three-dimensional pixels, +b emphasizes the intimate relationship between information, energy, resources and their impact on society and nature. +b stages the most extreme power released by humankind, irreversibly transforming the atmosphere and igniting the epoch of the nuclear Anthropocene with its application and supposed mastery of atomic power.The work illustrates how this mastery is really the reiteration of a profound error and the subsequent compounding of that error. We keep on making mistakes. Some of these errors are extraordinarily beautiful and useful, some are terrifyingly destructive with long-term planetary impact, and many are both.

Town after town refused to receive the radioactive goods. For the next four years, the homeless train cars rolled around the western edge of the USSR, leaving a trail of radioactive exposure. Finally in 1990, KGB officers took charge of the freight, burying the meat where it came from, inside the zone of alienation.

Had TMI, like so many of U.S. nuclear power plants now, been decades old and its metal pressure vessel embrittled and had shattered—a far greater disaster would have occurred.

But so far, somewhat miraculously, we have figured out how to live with the bomb. Now we need to learn how to survive the social web.

We must stop building new nuclear power plants, and find a real solution to our existing nuclear waste problem.

How will "STAY OUT!" be written 5,000 years from now? When we’ve had some kind of apocalypse, all society is gone, no one remembers America even existed, let alone how to read English. But we’re still drilling for oil.

Saddam’s Bomb: How close is Iraq to having a nuclear weapon?

Bush’s prewar claims, the failure of U.S. intelligence services to correctly gauge Iraq’s weapon-making capacity, and the failure to find any weapons of mass destruction—the Bush administration’s primary rationale for going to war—became major political debating points.

U.S. Secretary of State Rex Tillerson has continued to work on a diplomatic solution, telling CNN on Sunday he would continue to engage with North Korea “until the first bomb drops.”

we attempt to spell out here the likely consequences of the explosion of a single terrorist nuclear bomb on a major city, and its subsequent ripple effects on the rest of the planet.

Cuomo agreed to help keep the plants running with the aid of a multi-billion dollar bailout to be financed by monthly surcharges on the bills of ratepayers.

When you actually do the math, coal kills somewhere on the order of 4,000 times more people per unit of energy produced than nuclear power.

Iran's nuclear program

he 2015 Iran Nuclear Agreement Review Act gives Congress 60 days to review the deal before Obama can begin lifting sanctions. In theory, they could vote to block US sanctions relief, which would violate the terms of the deal — effectively killing it

Even though everyone knows Israel has the bomb, if you have a clearance and want to keep it, stick to discussing Israel's stockpile of strategic kumquats.
