Wave–particle duality operation of chemical reactions. Electricity, first thought to be a fluid, was now understood to consist of particles called electrons. This was first demonstrated by J. J. Thomson in 1897 when, using a cathode ray tube, he found that an electrical charge would travel across a vacuum. Since the vacuum offered no medium for an electric fluid to travel, this discovery could only be explained via a particle carrying a negative charge and moving through the vacuum. This electron flew in the face of classical electrodynamics, which had successfully treated electricity as a fluid for many years (leading to the
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
