If you have an undergraduate degree in physics, I would suggest — although I don't, so maybe it's not even true — but something close to that would allow you, with the information that's currently available, to actually build a nuclear weapon.
Si se han licenciado en física, le sugeriría... bueno, no, así que igual ni es verdad... pero algo parecido a eso le permitiría, con la información disponible, construir un arma nuclear.
