Why do people get arrested for being spies when they sell "nuclear secrets" to other countries, all the while the information on how A-bombs work is readily available on Wikipedia. Why does it takes so long for these crackpot nations to make a nuke when a simple internet search suffices? not troll, just brain filled with fuck.

none can trust wikipedia

Because wikipedia doesn't explain how to refine the uranium.

The problem isn't building the bomb, it's enriching the uranium. Read up on it, shit sucks. Sucks hard enough to keep 3rd world shitholes from having nukes. Unless that country is willing to starve its people so it can afford to hire scientists and build massive enrichment plants underground and in complete secret...

how do you enrich uranium? don't you have to like...soak uranium rods in heavy water or something?

>how do you enrich uranium?
Separate the isotopes of uranium.
step1) make UF6 (Uranium hexafluoride).
step2) separate the U235 from the U238.
step3) collect the U235
????
profit

expanding step 2
Centrifuges can separate the isotopes.
But here is how I would do it make a giant 100km long filter out of cigarette filters.
Put the UF6 in one end in pulses.
As each pulse pops out the end collect the first bit of each pulse. 1 cm long pulse in filter, collect first 5mm out other end. Take collected (slightly enriched) UF6 and repeat pulse procedure.

Thanks, I needed that.

No worries always happy to collaborate with fellow scientists.
Old washing machines would make great centrifuges.

The science part of it isn't that hard. The engineering part is hard. Especially the enrichment, since different isotopes of an element are chemically identical. I think originally they used a giant mass spectrometer to separate. I think now they mostly use centrifuges. But the engineering behind that isn't easy. Atom bombs themselves are easy in comparison.
