Quantum Quantum In physics, a quantum (plural: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. The fundamental notion that a physical property may be "quantized" is referred to as "the hypothesis of quantization". This means that the magnitude of the physical property can take on only discrete values consisting of integer multiples of one quantum. For example, a photon is a single quantum of light (or of any other form of electromagnetic radiation). Similarly, the energy of an electron bound within an atom is quantized and can exist only in certain discrete values. (Indeed,
The Physical Impossibility of Death in the Mind of Someone Living The Physical Impossibility of Death in the Mind of Someone Living The Physical Impossibility of Death in the Mind of Someone Living is an artwork created in 1991 by Damien Hirst, an English artist and a leading member of the "Young British Artists" (or YBA). It consists of a tiger shark preserved in formaldehyde in a vitrine. It was originally commissioned in 1991 by Charles Saatchi, who sold it in 2004, to Steven A. Cohen for an undisclosed amount, widely reported to have been at least $8 million. However, the title of Don Thompson's book, "The $12 Million Stuffed Shark:
