Petri dish be used to observe plant germination, the behavior of very small animals or for other day-to-day laboratory practices such as drying fluids in an oven and carrying or storing samples. Their transparency and flat profile also mean they are commonly used as temporary receptacles for viewing samples, especially liquids, under a low-power microscope. Petri dish A Petri dish (sometimes spelled "Petrie Dish" and alternatively known as a Petri plate or cell-culture dish), named after the German bacteriologist Julius Richard Petri, is a shallow cylindrical glass or plastic lidded dish that biologists use to culture cellssuch as bacteriaor small mosses.

The Dish (landmark) The Dish (landmark) The Dish is a radio telescope in the Stanford foothills. The dish was built in 1961 by the Stanford Research Institute (now SRI International). The cost to construct the telescope was $4.5 million, and was funded by the United States Air Force, with the original purpose of studying the chemical composition of the atmosphere. Later on, the Dish was used to communicate with satellites and spacecraft. With its unique bistatic range radio communications, where the transmitter and receiver are separate units, the powerful radar antenna was well-suited for communicating with spacecraft in regions where conventional radio signals
