Elementary particle quarks—now considered elementary particles. And within a molecule, the electron's three degrees of freedom (charge, spin, orbital) can separate via the wavefunction into three quasiparticles (holon, spinon, orbiton). Yet a free electron—which is not orbiting an atomic nucleus and lacks orbital motion—appears unsplittable and remains regarded as an elementary particle. Around 1980, an elementary particle's status as indeed elementary—an "ultimate constituent" of substance—was mostly discarded for a more practical outlook, embodied in particle physics' Standard Model, what's known as science's most experimentally successful theory. Many elaborations upon and theories beyond the Standard Model, including the popular supersymmetry, double the number
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
