Jean-Pierre Luminet, Black Holes, Cambridge University Press, 1987 THE ILLUMINATION OF FOUR TYPES OF BODIES Every natural body absorbs and reflects electromagnetic radiation in some way. The experiment illustrated in Figure 30 uses a parallel beam of light to illuminate several 'ideal' bodies, and to observe the reflected light in a direction perpendicular to the incident direction. The type of image received depends on the nature of the body and how it reacts to electromagnetic waves.

"Joules of the Universe". Diagram depicting all energy levels in the universe, beginning with a single photon, then progressing up to the energy of a hydrogen atom, the energy of an atomic bomb, the yearly output of the sun, and finally the total energy output of the universe. Memorable steps along the way include the energy in a ton of coal, and the energy of a bumblebee traveling at half the speed of light.

Supersymmetry: The Future of Physics Explained

The rumored upcoming announcement of the discovery of the Higgs boson on July 4 would put in place the last major thread of the Standard Model of physics. This might sound like the case is closed on how the universe works, but though the Standard Model answers many questions and has been very effective at predicting the existence of particles that were subsequently discovered, it also spawns a whole new set of questions that could prove very tough to conquer.

The Most Beautiful Experiment

Quantum physics informs us that a system exists in superposition — that is, in all possible states — until we observe that it is only in one specific state. According to a 2002 poll of …

Quantum Entanglement Holds DNA Together, Say Physicists

Quantum entanglement may be "spooky," but it works at a fundamental level of life processes. Deal with it.
