Point particle of point charges cannot be maintained in an equilibrium configuration solely by the electrostatic interaction of the charges. In quantum mechanics, there is a distinction between an elementary particle (also called "point particle") and a composite particle. An elementary particle, such as an electron, quark, or photon, is a particle with no internal structure. Whereas a composite particle, such as a proton or neutron, has an internal structure (see figure). However, neither elementary nor composite particles are spatially localized, because of the Heisenberg uncertainty principle. The particle wavepacket always occupies a nonzero volume. For example, see atomic orbital: The electron
How to Photograph an Atomic Bomb A traveling exhibit based on the book was purchased by the Atomic Testing Museum and put on display in 2007. In 2010, "The New York Times" featured a 23-image slideshow on its website with photos taken from the book accompanied by an audio recording of George Yoshitake, then one of the few surviving cameramen. How to Photograph an Atomic Bomb How to Photograph an Atomic Bomb is a book written by Peter Kuran and published in 2006 by VCE. It documents the stories of the men who photographed US nuclear weapons tests between 1945–1963 and the techniques they used to
