​Tldr: Don't worry about the electric shock, there is not nearly enough electricity there, let alone a good way to harvest it. Say it was just U 238 ore, and it went down the decay chain as normal. It would emit alpha/beta particles during its lifespan, eventually becoming lead. All the beta particles would be β-, and be coming from elements down the decay chain like Th, Po, Hg, and Bi. So now we have a bunch of α and β- particles being emitted, why wouldn't I get an electric shock? Well, there aren't nearly enough "electrons" present for this in the first place, so that's our first bottleneck. The second reason, and most important, is because they aren't flowing in a current. Imagine electricity as water in a bucket, being poured down a tube. This tube would be the path, like wires for example, and the water would be the electrons. The motion of the water going down the tube would be the electricity itself, and we could measure the 'current' of it based on how fast its moving. Now imagine a waterwheel at the end of this tube, with blades that spin when water hits it. If the tube has a good current, the blades are going to spin faster. If it has a slow current, it is going to spin slower, (if the tube is a constant size.). This is electricity, flowing, and doing work. Great! In radiation decay of β-, there is water e.g. electrons, but the problem is that there's not really a tube. We just have a bucket of water, its "evaporating" away at a given half life, becoming a cloud, and then raining. There may be the same mount of water, but its doing very little work to the water wheel, as its just kind of bombarding everything. Instead of being put through a tube and directed at the fans of this waterwheel, its going everywhere. This is what β- radiation would look like in this analogy. Yes, it will hit your keys, but it wont shock you. There is not really a current. If you wanted to look into this more, and you read this far, I strongly recomend you look into betavoltaics, and other radiation based batteries. They are really cool, even though they aren't the strongest batteries.

One factual error: it’s actually easy to keep a nuclear reactor operating at a steady level of power. The physics involved make reactors self-stabilizing. It’s not a matter of balancing on a knife’s edge; it’s a matter of getting into and staying in a deep rut. Making a nuclear weapon is far harder than making a nuclear reactor; you have to overcome those factors by creating a combination of unnatural conditions with a hundredth-of-a-millionth-of-a-second precision timing. Nuclear reactors cannot explode like nuclear weapons can. Worst case, they can spike in heat and cause a much smaller chemical or steam explosion.

Its not nearly so much a knife's edge as you make it out to be with regards to a fission reactor. Individual fuel pieces are large enough to generate enough neutrons such that, if you absorb a little fewer of them, the reaction gets back to where you want it with some ease. If anything, absorbing too many neutrons just reduces power output.

Thanks for the Becquerel exposure anecdote. It's crazy how certain discoveries might have been postponed if circumstances had not caused unintended experiments

Nuclear fusion: *I’m gonna do what’s called a pro gamer move*

Nuclear fission is sort of like balancing on a knife’s edge, as you put it. However, for anyone who doesn’t have a good understanding of nuclear power generation, its important to point out that in the case of a reactor core, this seemingly terrifying “knife’s edge”, where too many neutrons can cause a nuclear explosion, isn’t actually possible. There are two main reasons for this; 1) Fuel-grade Uranium is nowhere near enriched enough to sustain a runaway supercritical nuclear reaction that results in a nuclear explosion. Weapons-grade Uranium must be enriched to about 90% U-235 for a bomb to be possible. Fuel-grade Uranium is only enriched to around 3% U-235. Therefore, there just aren’t enough fissionable nuclei present in a fuel rod for this to occur. 2) Nuclear fuel rods, by virtue of being shaped as elongated rods, have way too much surface area for neutrons to escape the fissile material before triggering too many more fissions. For this very reason, a bomb core has to be a near-perfect sphere in order for it to actually work (in addition to being above the supercritical mass for the Uranium or Plutonium used). So even if the Uranium in a reactor core were weapons-grade (it never would be), and even if the neutrons were perfectly moderated (slowed down to maximize the probability of triggering more fissions, and hence releasing more neutrons), the fact that the fuel rods are rods completely ruins any possibility of the core ever acting as a bomb (and thankfully so!). Anyway, I just thought I’d add this information just so that nobody gets the false idea that the knife’s edge analogy means that nuclear power reactors are just one mistake away from being a potential nuke, which is impossible.

I did a bit of simple math when it comes to special relativity but while I grasp general relativity in a more intuitive way, I have not done the math but I do understand to some extent why the calculations are way more complicated. When it comes to plagiarism: wasn't he the first to state that something that has mass inherently has energy? Saying he had zero original contribution is simply false.

Wow, and to think (I believe) all of the people whose quotes were featured were still around just over 10 years later when all of that became absolutely possible, and most saw it become used in power plants as well!

MrRolnicek Yes that's possible. While this is not my field, I try to follow along. Dark matter may turn out to be WIMPS or something much like it. My point is that this is not known yet. Darkside is not entirely clear in its results best I can see. Nor has it been replicated. The rest is hypothesizing. Rocks are my field and I get your reference about mysterious radiation. I would love for either dark (side) phenomena to result in something similar - in my lifetime.

The key to sustained, stable chain reactions is the fact that some of the fission neutrons generated are delayed by as much as a few milliseconds. That transforms the "knife edge balance" problem into a trivial control problem. Well, that and the design of the reactor to only achieve criticality with thermal neutrons, i.e. neutrons moving as slowly as a hydrogen atom at room temperature. The probability of a neutron causing a fission is maximum at such low energy, and drops dramatically with increasing neutron energy. So reactors have to employ a moderator, to slow down the fission neutrons - something like hydrogen (as in water) or carbon (as in graphite). It's best not to use both, or you get a Chernobyl situation, just FYI.

It includes accounts of such things as Fermi's construction of the first atomic pile (i.e. first primitive nuclear reactor) in Chicago, including discussions of how he ensured that it would operate enough, but not too much... Rhodes's book is a must read.

We like to remember bad predictions by people who aught to know better. We don't bother to remember the good predictions by the knowledgable or any prediction by idiots.

I feel like your comment on nuclear power plants becoming unstable due to absorbing too few neutrons, while true, is misleading in that you mentioned the explosion at Chernobyl after talking about nuclear bombs. The explosion at Chernobyl was not a nuclear one. A nuclear power plant (even a poorly designed one like Chernobyl) just doesn't have uranium in a dense enough formation to make that happen. The explosion at Chernobyl was actually caused when the balance you were talking about caused a rapid buildup of steam pressure which ruptured the reactor and spread fuel and fission products into the atmosphere. It saddens me to see the misconception "Nuclear power plants are unsafe because they can become a nuclear bomb." being spread anywhere and I like to do what I can to stop it. Nuclear power is statistically the safest, and most efficient, form of energy by far, and its arguably the cleanest form of energy production as well. Unfortunately we wont use it because we are afraid of it due to wrong and outdated information and misconceptions. I've been a subscriber to your channel for years now and love all of the content you put out. You do a fantastic job of teaching people about science, and the universe around us.

What happened at Chernobyl was no less than a nuclear catastrophe. Irrespective of the cause, the effect was ten times that of Hiroshima, and it wouldn't have happened if it weren't a 'nuclear' plant. So directly or indirectly, his statement is right.

Leo Szilard penned the letter, with support from Eugene Wigner and Edward Teller. He persuaded Einstein to sign it to give it more weight. When Szilard and Wigner explained the risk of a nuclear chain reaction in Uranium using a neutron moderator that could be used as an atomic bomb on July 12 1939 Einstein commented "Daran habe ich gar nicht gedacht" ("I did not even think about that").

10 years have passed... Should make a updated video

3:14 Never having thought about it in that way, I think it is quite amazing that the energy from a single nuclear reaction is only an order of magnitude off from some vaguely "macroscopic" energy.

@@ericdew2021 A nuclear reactor even has to go supercritical in order to start working in the first place ("critical" = the chain reaction is self-sustaining), it is just done in a very different way to a nuclear bomb in order to keep the reaction controllable. Not all the material is put in one big lump, but it is spread across a large volume and the neutron energy is influenced using a moderator, their number using control rods, in order to control the power output. Another part in keeping the reaction controllable is relying on delayed neutrons that are not released basically at the moment of a fission happening, but some time later (on the order of seconds) as part of the decay of the fission products. This makes the time constant of changes in the output power long enough so it becomes controllable by technical means. The problem in Chernobyl was that the reactor went prompt supercritical, thus the power increased exponentially with a time constant that was too short to control (remember, mechanical systems moving large, heavy parts around), until physics (the steam explosion) dispersed the material enough to end the supercritical state.
