So when the school does all ot legally can to teach a person and that person does all they can to nor learn then it's that persons own stupidity that they are dumb. When those paying for the school see that students don't want to learn grades going down and nothing is changing it those schools become just daycare and hangouts as Noone wants to put money where there is no turn around. so they stop plugging in money. And I could drag this out for parents society entertainment and personal responsibility. But I might as well just write a book at that point. So people being stupid is their own fault in the end cause of their own choices. Any argument against that neglects to take into account when from these low income and poverty stricken areas and schools some people still succeed. and now with all knowledge at our finger tips. If you are a stupid person it's your own fault.

So I told him that the first weapons were built back in the 40’s with no computers, and no way to know if their designs would work. They also managed to pull off nuclear fission with nuclear fuel that they had to make. The bomb that blew up Hiroshima is about as simple as you can get, take two pieces of uranium 235 and combine them them violently and boom. He was still skeptical until I went on Wikipedia and showed him the design.

Iron can and is fused in the largest stars, however it doesn't occur for very long because fusing iron does require more energy than is released during fusion (net energy loss), causing the star to lose its battle with gravity. When gravity wins, the stellar material free-falls toward the denser core, rebounding off it in a tremendous explosion called a supernova.

@Fordi

6 жыл бұрын

All of the Fukushima reactors were offline (that is, not fissioning) by the time the tsunami hit, but they still had a lot of decay products (the things left after fission happens) left. Decay products are highly radioactive, and usually after the control rods are inserted (stopping fission), it takes up to 72 hours for the decay heat to fall to levels where the heat can be passively removed. The flood shut down the active decay heat removal systems. Without decay heat removal, the temperature within the core of reactor 1 rose, until it was hot enough that the fuel cladding started to react with the coolant water, releasing hydrogen. Meanwhile, pressure was high enough, due to the high temperatures, that hydrogen could diffuse through the metal walls. Eventually, when the hydrogen was sufficiently mixed in with the outer air, it exploded, blowing off the skin of the building going out, and damaging secondary containment going in. Similar situations occurred in reactors 2 and 3, on slightly longer timelines, since they were newer and had slightly better passive heat removal. Reactor 4 had been defueled for maintenance, and didn't go up. Reactors 5 and 6 had sufficient passive heat removal that they just about avoided explosions (though, they did suffer internal pressure damage). In short, gordon is correct. They did not blow because of fission; theirs were not "nuclear" explosions.

@davidwalters9462

Bryan, well stated. That's is exactly right. Some anti-nuclear people purvey the lie of fission occurring, which it didn't. The meltdown happened because the fuel to the emergency diesel generators was wiped out (stupidly the put the fuel tanks for the diesel fuel at the intake structure because it was...*cheaper*). At any rate the tsunami is what really caused the meltdowns to occur. Also, it is worth pointing out that no one has died because of this happening. World wide the nuclear operators went through a paradigm shift in safety, establishing auxiliary pumps, station-black out scenarios, hardening intake structures and so on. Nuclear energy has killed few people than any other source of energy EVER. Something to think about when people start screaming at the moon. I feel sorry for the farmanimalfriend who purveyed this nonsense and actually doesn't know what occurred at Fukushima's reactors.

@sabotsabotskij7047

Agreed. If you're going to oppose nuclear energy - at least do with reasons based on facts regarding nuclear power plants. Newer reactor designs are far safer and resistant to meltdowns caused by natural disasters such as the one at Fukushima. The only unavoidable problem with fission reactors is the highly dangerous waste product that is expensive to store safely. It's still safer than fossil fuels right now, and it's cheaper than going full renewable. The only scenario where it's not a win-win to utilize fission energy is if commercial fusion energy were actually a viable option in the forseeable future.

@timframe570

James Godfrey I want to preface that I believe nuclear is the solution to our power needs and support nuclear power in general. The MSR, however is a better design then LWRs for some essential reasons. First the MSR is walk away safe. This is possible for several reasons. The MSR is designed to operate at high temperatures and is already in a liquid homogeneous form. As the temperature increases in an uncontrollable situation a salt plug will intentionally melt where the reaction fluid will drain into a kill tank. This tank has neutron absorbing materials killing the fission process. The LWR relies on water and due to the temperature requirements for the power generation cycle, it must operate at high pressures. The high pressures require pressure vessels and a massive containment dome that dramatically increase cost and the severity of a meltdown is higher due to the potential pressure vessel rupture. The water itself is an issue due to the fact that free neutrons cause water to break into its components and must be recombine to recycled. Additionally the MSR being a homogeneous fluid is far more fuel efficient than solid fuel reactors. Within the MSR we can use thorium, used fuel rods and decommissioned nuclear weapons as fuel. The waste streams half-life is considerably shorter in the range of 300 years rather than 100,000+. There are technical challenges with reprocessing and others but these can be solved.

Always considered it a testimony to the genius of man to be able to develop such an incredibly complicated, expensive and dangerous way to boil water.

Very cool! Always cool to learn something new! I greatly appreciate this channel and the information that you guys bring!

Don't think they were consciously being ironic. I think the point was supposed to be that we should use solar power instead of nuclear power. The irony (for those who don't get it) is that the sun IS a nuclear (fusion) reactor that is 333,000 times the mass of Earth. Granted, it's 150,000,000 km (93,000,000 miles) away, but it's a nuclear reactor nonetheless.

I love it when stuff is explained clearly and it just fits together and makes sense.

I love the dynamic between these two. I want to just sit and watch them at a bar... With a friendly neutron...

Don’t you usually use uranium 235 atoms, which create 3 and not 2 new neutrons?

I had to go look it up. It seems the number of neutrons varies depending in the speed of the incoming neutron. The equation I found for u235 shows the numbers as 2.4

no, uranimum 235 creates 2.03 neutrons per fission.

Curious, where do they get the neutron from to start the reaction?🤔

solar power is nuclear power

Could you explain kinetic kill in detail PLEASE.... have been really wanting to know about it for quite sometime now THANKS!!

They'd also tell all parents that if their children were playing RP games instead of football that would lead to them being possessed by demons. Sooooooo yeah this is far from any scientific method, in fact they do the exact opposite and try to make it look like a fact when it's just biaised info with no evidence and no method, just to prove a point they otherwise wouldn't be able to, using emotions and feelings as proofs where they are in fact the very reason of why their method is wrong and far from any science. Sad days. Loads of church people have been huge pioneers in sciences over the centuries, it's so sad to see obscurantism go back up IMO.

Great series!

Neil knows his physics, he understands public relations. But he has zero public service experience. No school board. No city government. No state or federal government experience. Not sure he'd want to anyway, as an elected official he'd have to talk about stuff other than space and physics.

We need nuclear power. And alot more of it.

Very expensive to build compared to any other way of generating electricity and you cannot ramp them up or down quickly so you still need energy balancing like with renewables... There is good reason nuclear is not talked about very much anymore, even solar photoelectric generation has been cheaper to build out than nuclear for at least 30 years...

Why? All other forms of electrical power generation are cheaper to build out. Nuclear plants cannot ramp up or down fast enough to balance the grid so they face the same situation as renewables except you have far greater cost to build and cost of fuel and no nuclear power plant has yet included the cost of storing nuclear waste safely for over 10,000 years.
