Photocathode
A photocathode is a surface engineered to convert light (photons) into electrons using the photoelectric effect. Photocathodes are important in accelerator physics where they are utilised in a photoinjector to generate high brightness electron beams. Electron beams generated with photocathodes are commonly used for free electron lasers and for ultrafast electron diffraction. Photocathodes are also commonly used as the negatively charged electrode in a light detection device such as a photomultiplier or phototube.

Original Affluent Society
The "original affluent society" is the proposition that argues that the lives of hunter-gatherers can be seen as embedding a sufficient degree of material comfort and security to be considered affluent. The theory was first put forward in a paper presented by Marshall Sahlins at a famous symposium in 1966 entitled 'Man the Hunter'. Sahlins observes that affluence is the satisfaction of wants, "which may be 'easily satisfied' either by producing much or desiring little." Given a culture characterized by limited wants, Sahlins argued that hunter-gatherers were able to live 'affluently' through the relatively easy satisfaction of their material needs. At the time of the symposium new research by anthropologists, such as Richard B. Lee's work on the !Kung of southern Africa, was challenging popular notions that hunter-gatherer societies were always near the brink of starvation and continuously engaged in a struggle for survival. Sahlins gathered the data from these studies and used it to support a comprehensive argument that states that hunter-gatherers did not suffer from deprivation, but instead lived in a society in which "all the people's wants are easily satisfied."
