Approx. volumes of the Fat Man Pu core (6.2 kg) versus the amount of uranium metal it took to produce it (~28 tons).pic.twitter.com/nnLWeminrQ

@wellerstein Remarkable how *little* space 28 tons of U takes up; atomic density hit home for me first time I lifted a small block of lead.
@GWilliamThomas @AstuteDoofus I think we are just not familiar with seeing solid blocks of metal? Alum. cubes wd be 10" larger on each side

@wellerstein@AstuteDoofus That said, when you lift a small block of a heavy metal, you notice the difference with, say, iron. -
@GWilliamThomas@AstuteDoofus Agreed! I have handled uranium metal before and it is much heavier than it looks.

@wellerstein@AstuteDoofus That's a good point, re: total volume (standard comparison for me would be a 2-ton car, which is largely air).Thanks. Twitter will use this to make your timeline better. UndoUndo
