- Big Brother (Nineteen Eighty-Four) (Wikipedia)
Big Brother is a fictional character and symbol in George Orwell’s dystopian 1949 novel Nineteen Eighty-Four. He is ostensibly the leader of Oceania, a totalitarian state wherein the ruling party, Ingsoc, wields total power “for its own sake” over the inhabitants. In the society that Orwell describes, every citizen is under constant surveillance by the authorities, mainly by telescreens (with the exception of the Proles). The people are constantly reminded of this by the slogan “Big Brother is watching you”: a maxim that is ubiquitously on display throughout the novel.
- Lichen (Wikipedia)
A lichen (/ˈlaɪkən/ LY-kən, UK also /ˈlɪtʃən/ LITCH-ən) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship. Lichens are important actors in nutrient cycling and act as producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not plants. They may have tiny, leafless branches (fruticose); flat leaf-like structures (foliose); grow crust-like, adhering tightly to a surface (substrate) like a thick coat of paint (crustose); have a powder-like appearance (leprose); or other growth forms.
