Cell culture molecular biology primarily involves cultures of cells on flat plastic dishes. This technique is known as two-dimensional (2D) cell culture, and was first developed by Wilhelm Roux who, in 1885, removed a portion of the medullary plate of an embryonic chicken and maintained it in warm saline for several days on a flat glass plate. From the advance of polymer technology arose today's standard plastic dish for 2D cell culture, commonly known as the Petri dish. Julius Richard Petri, a German bacteriologist, is generally credited with this invention while working as an assistant to Robert Koch. Various researchers today also
Myth of the flat Earth "Comical History of the States and Empires of the Moon" (published 2 years posthumously in 1657) quotes St. Augustine as saying "that in his day and age the Earth was as flat as a stove lid and that it floated on water like half of a sliced orange."
