obtaining the nuclear material that makes a nuclear bomb go boom. the hiroshima bomb in 1945, it was basically structurally speaking, a gun. inside the outer casing that looked like a cartoon version of a bomb was basically a gun mechanism used an explosive charge to fire a piece of highly enriched uranium into another piece of highly enriched uranium. that create create add nuclear reaction and a nuclear explosion. the second bomb the u.s. dropped on japan three days later, that was built in a different way. again, used an explosive charge. in this case, it was used for a different material. the nagasaki bomb used an explosive charge to squeeze together a hunk of plutonium. and that is how the nagasaki nuclear reaction was setoff. those two american bombs remain the only two nuclear weapons ever been used as weapons in
the hard part is step two. obtaining the nuclear material that makes a nuclear bomb go boom. the hiroshima bomb in 1945 it was basically structurally speaking a gun. inside the outer casing that looked like a cartoon version of a bomb was basically a gun mechanism used an explosive charge to fire a piece of highly enriched uranium into another piece of highly enriched uranium. that create create add nuclear reaction and a nuclear explosion. the second bomb the u.s. dropped on japan three days later, that was built in a different way. again, used an explosive charge. in this case it was used for a different material. the nagasaki bomb used an explosive charge to squeeze together a hunk of plu tomorrowium. and that is how the nagasaki nuclear reaction was setoff. those two american bombs remain the only two nuclear weapons ever been used as weapons in
and prosecutors saying influencing the legal proceedings of his girlfriend. menendez could spend decades in prison. he said nothing about resigning his senate seat at that press conference we showed you today. but, other big news here tonight. the senator said he notified leadership he will, he will temporarily step down from his crucial post as a top democrat on the foreign relations committee. and that has major implications on the entire iran debate. in this post, menendez was the most powerful democrat on foreign policy in the senate and huge thorn in the side of president obama s iran controversy. the white house said it could undermine the late-stage negotiations. he crossed the president on many other issues. here s another interesting piece tonight. they re suggesting that that long-running feud is why he was targeted by prosecutors in obama s justice department. that s an explosive charge, though the investigation
aircraft will then fly through so is the shrapnel actually the warhead or is the warhead packed with shrapnel no, no, what they do is they have the explosive charge, which only turns out to be about 50 pounds i guess, but then there s 100 pounds of metal that wrap around it, and it s scored on the inside into a diamond pattern. like brake lines when you put so the explosive force turns the casing of the warhead into this thousands of pieces of shrapnel and they re uniform sized diamond shaped. so that actually just pierces the exterior of the aircraft? right. it s so very likely that a number of people were killed instantly from shrapnel. well, it would depend on where it penetrated the aircraft. it looks like from the diagram that the government released that it came up from the front of the aircraft, but it looks like the explosion was probably underneath the aircraft and came up under the tail.
radio that they re going to hit certain neighborhood. other times, they ve called homes and said to the people inside, get out, we re about to hit your place. other times they fly over and drop leaflets explaining where they re going to hit, which roads are clear for evacuation and when people need to move. some of those leaflets say things like israel is currently attacking and will continue to attack every area from which rockets are being launched at its territory. one other way they warn, the fourth way, is probably the most controversial. that s called roof knocking. they fire a low explosive charge or a missile with no charge to hit the roof of the building, to warn the people inside they re about to be hit as they will be in moments with a much more powerful missile that can level the whole structure. the israelis say they re saving lives by doing this. the palestinians say this is psychological warfare. that it s about keeping people off base, keeping them afraud. the israelis
