yeah it was a little pov but its not dissolved.

even if it dropped to 1/3 of levels its not like it would not be formidable. Maybe it would fail but its still a major hassle to deal with (you would still need a total psychopath to engage it). Dissolving it however.......

pretty sure I heard t say that we don't need nato at all

and on the plus side those countries are kind of paying indirectly by being the potential battle zone and keeping down the cost of the navy and air force, because im pretty sure the navy budget would rise by 500000 percent if they made it to the western side of the ocean

its much cheaper to contain them on land

also if you tax those people too much they will just turn communist because its not like it does not work, you need to offer a better deal. lots of ambivlant people that will just take whatever is slightly better.

It's always been Eastern Europe (and South, I guess?) which had to deal with external enemies.
For the last thousand years the only enemies of Westerners were themselves, and overseas bushmen here and there.

They don't get it. Ruskies scared them for a while, but they thought the Cold War was over.

Really? The Americans don't seem to have got the message. They've continued manipulating things in Europe since the USSR fell, like that event never happened.

I think it was an allusion to things getting somewhat "hot" recently.

I can't pretend to understand why American foreign policy over the last 30 years has been what it is.  Inertia certainly is one factor, but I am sure there are many others.  Leaving Europe alone has a many century history being a problem for the neighbors.  Hubris, thinking of ourselves as ruling the world is another.  The list goes on and on.

I can sit here and point out lots of ways we could have done it better, but it wasn't my job, and wasn't a job I would have taken on under any circumstances.  And the people I voted for that I thought would have done a better job either didn't win, or didn't live up to my expectations.

Oh, and I was referring to the fact that the warfare currently is much hotter than any time during the Soviet era, and is in real danger of heating up more.  None of the three major general outcomes of the heavy fighting in Ukraine bode well for the future (Complete Russian success in Ukraine, continued high intensity stalemate, or complete Ukrainian victory).

Did I suggest they were? Every government in the world is perpetually trying to screw every other government to the maximum extent they think they can get away with. Its what makes the dynamics of things like the EU such a joke.

Oppenheimer seems to be a winner at the Golden Globes awards.

Then again, those who vote at the Golden Globes are a different species of critic to science & technology enthusiasts (they're entertainment media journalists).

Nixe Tube invention is credited to 1955 or so.
So why is there a Nixie clock countdown at Trinity?
Because it looked cool for the movie?

Saw that  on Youtube and gave up on watching the rest of the movie.  Am I the only person on the planet that caught that detail? 

For those folks debating Bridgewires, Mound Lab, here in Ohio, was bragging about diode laser pumped,  fiber optic detonator development long ago. Much easier to sync.
Mound was being closed at the time, so it's various divisions were looking for ways to survive.
Hence the news articles on Fiber Optic Detonators.

Krytrons were always dangled as bait to catch the un-weary. Contrary to popular belief, they are not that difficult to make, if your nation has/had a domestic lighting or vacuum tube industry.

"Whizzer"
 neutron generator designs have been published The tube has its own gate/trigger electrode, so let's despell the myth that triggering it requires some sort of mystical HV sync circuit.

Ref: https://pubs.aip.org/aip/rsi/article-abstract/70/1/1104/444254/Compact-neutron-generator-for-diagnostic?redirectedFrom=fulltext

Those who ignore technological history are bound to claim it's redevelopment.

Was digging through the library at work  { Unclas, Academic}

and was shocked to find a Kapton Tape based "slapper" paper bragging on kilometer per second velocities for very cheap. At the time Kapton was not cheap, but always wanted to try to copy the design in that publication.  In today's world Kapton foil
is s commodity material.

The magic is in the computation,materials processing, machining, gas injection, and explosive lensing. The basics of lensing has been well documented in a recent Youtube video.


What is  amazing is how many processes and materials relating to building a "gadget" have been published.

The fact of the matter, is the scarcity and cost of the required metals is all that's  keeping us safe.


As to Vad's comment..1.21 is the key to the Universe. :clap:

And at least now, krytrons are not required for high voltage fast switching.  I was actually surprised how poor krytrons perform based on the published datasheet.

The magic is in the computation,materials processing, machining, gas injection, and explosive lensing. The basics of lensing has been well documented in a recent Youtube video.

I have done the math for the geometry of an explosive lens, but for a different application.  However the explosive lens geometry requires some empirical testing because of non-linear variation in the velocity of propagation.

 I don't think DoE and the USSR maintain all sorts of device myths jointly,. I have an educated guess that a few things used for proliferation monitoring are kept very, very, quiet by mutual agreement of all parties who have devices.  Let's face it, the nuclear industry worldwide has a great PR and recruiting machine. Hiring people who ask really good questions insures a fresh stock of skilled people. So if Hu checks book X out of your library, we're from the Goverment, let us know... Hum, great recruiting tool.


What I think holds back common knowledge in this case are the journalists and book authors regularly regurgitating the same poor explanations over and over again. 

My high school Physics and Electronics teacher was a highly skilled skilled Electrical Engineer with a Masters and extensive military and civil reactor  experience. Yet he still taught us that electrons flow from negative to positive outside the battery.
Even back In 1984 and 1988 I. knew "flow" was probably the wrong choice of words, but right or wrong on the theory, Veritasium at least tried to set the record straight for fun and profit.

Now mind you, as someone who frequently finds himself informally teaching, I know you have to start with easy analogies sometimes, but the amount of stringed along bad simplifications in this world are legion.

I've yet to hear a really good explanation of how base current in a transistor works, it's only taken something like the Internet to make a good theory accessible to me, and I've had access to some of the best science libraries in a five state region.

I've had some real problems in the past using EE and ET and Physics models with Chemists and Chemical Engineers.

Approximations I've been taught  hold up well for my applications. However when you jump fields [pun intended] it may not go well when collaborating.

 Just try to explain Tan D  or Electret behavior to a Chem Eng.

At the University, some of the Chem Eng types have offices right next to EE Profs, but they might as well have been in different universes.   Conversation starts about Laplace and Maxwell and the strategic retreat begins.  Ok, call the Technician...(Me) which used to end in a trip to the now abolished science library for "easy" materials texts. We don't keep books anymore though,   Science Librarians are just too expensive. 

Just a rant, I've had people tell me nuclear and atomic bombs are two different things.

Just refer to them all as "conversion weapons", which is short for "mass-energy conversion weapons".

trump should read red dawn because that what happens when you defund nato


   IIRC it wasn't NATO that Trump wanted to defund, it was the UN.  (And I completely agree!  The UN has been WORTHLESS in preventing the current wars in both Gaza and the Ukraine. And also utterly useless in stopping the attacks on commercial shipping in the Red Sea.)

Indeed - there are subtle differences in the nomenclature between 'nuclear weapons' and 'atomic weapons.'

Atomic bombs are understood to be fission devices.
Hydrogen bombs are understood to be fusion devices.

Nuclear weapons is a catch-all to refer to both collectively.

The distinction is important because some countries had A-bombs figured out before H-bombs and, as the film Oppenheimer tries to explain, there was controversy over whether the US should or should not have pursued H-bombs after figuring out A-bombs.

It's the ol' logical syllogism. A Frenchman is a European but a European is not necessarily a Frenchman.  :P

We're venturing dangerously close to partisan politics here, so I'll respond to this in as civil a way as I can before leaving it.

As an isolationist, Trump had contempt for both NATO and the UN. Honestly IMO I'm not sure he understood the difference.

This was presented often in the news during his first term and was discussed heavily in some of the books written by his insiders, especially John Bolton's book. Trump wanted to heavily cut the US contributions to both, and was expected by many to pull the US out of NATO entirely if he were elected to a second term.

What's with the wary/weary confusion that's everywhere all of a sudden? Never used to see it.

Note the complete contrast with the current occupant, whose contempt for the institution is such that when he wanted to veto the Security Council resolution called by the Secretary General according to Article 99, he didn't even send his real ambassador.

Helius, my. phone has tried in the past 10 seconds to force a name change for you.   I had to override it to type your name.
It wished and desired to change you to Helium or Helios.

I suspect therein lies the answer.
My phone, snd most forum sites, abhors indentation, for example.

I can imagine. I can see a world in which you get overrun and dominated by the armies who didn't cut back. I can imagine a world in which that doesn't happen, but that doesn't include human beings.

If NATO had balls they could have overrun Russia and China when there was an opportunity in the '90s, installed democratic governments in those countries and thus made them equally corrupt and lazy as NATO.

Then there would be peace :-DD

I think that Pax Americana was/is better than most of the likely alternatives.  Not perfect, but as coppice points out: humans.

And I also think that Oppenheimer was a very good movie, an interesting story told in an interesting manner.
