Photoelectric effect

In physics, Compton scattering is a type of scattering that X-rays and gamma rays undergo in matter. The inelastic scattering of photons in matter results in a decrease in energy (increase in wavelength) of an X-ray or gamma ray photon, called the Compton effect. Part of the energy of the X/gamma ray is transferred to a scattering electron, which recoils and is ejected from its atom (which becomes ionized), and the rest of the energy is taken by the scattered, "degraded" photon.

Heisenberg's gamma ray microscope

Heisenberg's gamma-ray microscope for locating an electron (shown in blue). The incoming gamma ray (shown in green) is scattered by the electron up into the microscope's aperture angle θ. The scattered gamma-ray is shown in red. Classical optics shows that the electron position can be resolved only up to an uncertainty Δx that depends on θ and the wavelength λ of the incoming light.

Chaos star

The Symbol of Chaos originates from Michael Moorcock's Eternal Champion stories. In them, the Symbol of Chaos comprises eight arrows in a radial pattern. In contrast, the symbol of Law is a single upright arrow. It is also called the Arms of Chaos, the Arrows of Chaos, the Chaos Star or the Symbol of Eight.

Moorcock contends that he conceived this symbol while writing the first Elric of Melniboné stories in the early 1960s. It was subsequently adopted into the pop-cultural mainstream, turning up in such diverse places as modern occult traditions and role-playing games.

Chaos sphere

The chaosphere is a popular symbol of chaos magic.
Chaos magic is a school of the modern magical tradition which emphasizes the pragmatic use of belief systems and the creation of new and unorthodox methods.

The Penrose triangle

The Penrose triangle, also known as the Penrose tribar, is an impossible object. It was first created by the Swedish artist Oscar Reutersvärd in 1934. The mathematician Roger Penrose independently devised and popularised it in the 1950s, describing it as "impossibility in its purest form". It is featured prominently in the works of artist M. C. Escher, whose earlier depictions of impossible objects partly inspired it.

Tychonian system

Diagram depicting the basics of the Tychonian geocentric system. Basically, the objects on blue orbits (the Moon and the Sun and the fixed stars) revolve around the Earth. The objects on orange orbits (Mercury, Venus, Mars, Jupiter, and Saturn) revolve around the Sun. All is surrounded by a sphere of fixed stars (though they are fixed only with respect to each other, for the sphere revolves around the earth). The system is essentially geocentric, though everything except for the moon and the fixed stars and the earth centre itself revolves around the Sun.
