What is Atomic bomb: Definition and 21 Discussions
A nuclear weapon (also called an atom bomb, nuke, atomic bomb, nuclear warhead, A-bomb, or nuclear bomb) is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or from a combination of fission and fusion reactions (thermonuclear bomb). Both bomb types release large quantities of energy from relatively small amounts of matter.
The first test of a fission ("atomic") bomb released an amount of energy approximately equal to 20,000 tons of TNT (84 TJ). The first thermonuclear ("hydrogen") bomb test released energy approximately equal to 10 million tons of TNT (42 PJ). Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can release energy equal to more than 1.2 million tons of TNT (5.0 PJ).A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deployed twice in war, by the United States against the Japanese cities Hiroshima and Nagasaki in 1945 during World War II.
Just watched Oppenheimer. It's amazing how they can make the bomb explode at first try, and also dropped them at Nagasaki and Hiroshima at first try. Is it possible that it's easier to make an atomic bomb than assumed by the public?

HI,
Id like someone to assist me please. the nearest what I would consider nuclear target is 14.7km from my house as the crow flies.
The presumed explosion is 800 kilotons air burst
My house is brick built, modern double glazed windows. Diagonal on from the explosion. Nuke map indicates I...
I recently looked at a transcript of a 1991 interview of Hans Bethe, where he recalled the suggestion that an atomic bomb could ignite the air.
"Teller at Los Alamos put a very good calculator on this problem, [Emil] Konopinski, who was an expert on weak interactors, and Konopinski together...
In Fog Of War, a superb documentary about the life lessons learned by Robert McNamara is mentioned the design development and detonation of a 100 megaton bomb. I have no reason to doubt what McNamara said was untrue or a lie, what's the point of that anyway?
Anyone have any ideas how such a...

Hello mates.
I was wandering how to analyze an atomic bomb, when the only information given, is that the bomb contains 5,6 kg plutonium, and is the same model as fat man.
Do you have any...
Before I got into physics, I thought that ##e=mc^2## was the atomic bomb equation. I now know that the equation itself has nothing to do with the atomic bomb. So, I'm wondering, how did ##e=mc^2## contribute to the development of nuclear/atomic weaponry/power?
Edit: I do not know if this is in...

"However uranium-235 (U235) makes up only 0.72% of normal uranium metal and has to be separated from the remainder (mostlyuranium-238) in special factories which makes uranium-235 (U-235) a little more expensive. An uranium-235 (U-235) atomic has three neutrons less than an...

"Told science"
Hi guys!
I am going to take part in a literature project, which is called "told science". You have to write a scientific eassy such as a story. For this year I was wondering to write down something about the atomic bomb. My idea was to write the best quotation on atomic bomb in...
I am an afficionado of all weaponry, and there is this question I have which has bugged me for a while. What, exactly, makes a Hydrogen bomb different from an atomic bomb? I realize that the explosive is Hydrogen as opposed to Uranium or Plutonium, but why is it more powerful?
Homework Statement
I am having some trouble with this one,
Suppose an atomic bomb was exploded in a box that was strong enough to contain all the energy released by the bomb. After the explosion the box would weigh:
a) more than before the explosion
b) less than before
c) no change...

Hi everyone. I've been searching google for a clear formula and formulas for atomic/nuclear bomb shockwave and blast radius. I haven't come across anything remotely close that details the effects of time on the effects of the bomb as it crosses a set distance. Can some one help me with the...
Hello everyone I am new to PF actually this is my first thread. I am looking for the equation to see how far and how, the radiation from the Nuclear Blast using E=mc^2. Can anybody help? Please[?]
