Laboratories used for scientific research take many forms because of different requirements from specialists in various fields of science and engineering. Physical laboratories may contain particle accelerators or vacuum, while metallurgical laboratories can have metal casting or refining equipment or to test their strength. A chemist or biologist might use a wet laboratory, while a psychologist's laboratory might be a room with a one-way mirror and a hidden camera to observe behavior. In some laboratories, as commonly used by computer scientists, computers (sometimes supercomputers) are used both for simulation or data analysis. Scientists in other fields will use other types of laboratories. Engineers use laboratories also to design, build, and test technological devices.
Scientific laboratories can be found as research rooms and study spaces in schools and universities, industry, government facilities, or the military, and even on ships and spacecraft.
