The Riddle of the Third Idea: How Did the Soviets Build a Thermonuclear Bomb So Suspiciously Fast?Gennady Gorelik
the death of an astronomical heavyweight is a showstopper. It has spent its life cannibalizing its own innards -- and sometimes the innards of a solar neighbor -- for fuel. When there is nothing left for it to consume
The probability of a U-235 atom capturing a neutron as it passes by is fairly high. In a bomb that is working properly, more than one neutron ejected from each fission causes another fission to occur. It helps to think of a big circle of marbles as the protons and neutrons of an atom...
However, with enough energy, this can be overcome, and because nuclei with a smaller atomic number have fewer protons, the Coulomb force is overall weaker and requires less energy to break past. Generating this energy involves creating high temperatures and pressures. Thermonuclear fusion creates a...

How is energy from the Sun distributed around Earth? What is a thermonuclear reaction in nuclear physics? What is the difference between nuclear physics and science? How is technetium-99m used in nuclear medicine? Compare radioactive and stable nuclei. Why is mass not conserved in a nuclear re...
there was "a dearth of people with relevant practical experience in the conduct of thermonuclear wars," practical experience had to take a back seat to theory. In 1968, Kahn described his approach, and its major liability, with a characteristic blend of chutzpah and self-deprecating wit: "We...
Casing of a U.S. W53 thermonuclear warhead What I've found interesting, as a Bin Laden observer, was his silence about the Arab Spring. Why would he be silent when, since 9/11, Bin Laden has released over 30 videotapes and audiotapes? He has commented on any ...
(So yes, a crowd of humans the size of the Sun's core could produce just as much heat as the Sun, in theory. That is, as long as you can keep them alive.) This is probably very different than your conventional view of fusion, which likely takes a small "mass" like this... ...
