Turnstiles at Alewife subway station in Cambridge, Massachusetts

A turnstile, also called a baffle gate, is a form of gate which allows one person to pass at a time. It can also be made so as to enforce one-way traffic of people, and in addition, it can restrict passage to people who insert a coin, a ticket, a pass, or similar. Thus a turnstile can be used in the case of paid access (sometimes called a Faregate when used for this purpose), for example public transport or a pay toilet, or to restrict access to authorized people, for example in the lobby of an office building.

Nanotechnology Is BIG at NIST (5682 words)
Consider work under way at the National Institute of Standards and Technology (NIST), where research truly is pushing the limits of technology.
Here, scientists and engineers are building atom and electron counters, single-photon turnstiles, ultracold ion and atom traps, and lasers that generate uniform pulses of light that last only a few trillionths of a second.
For NIST, the quest to design, manipulate, manufacture, and assemble at the molecular and atomic levels translates into a full agenda of demanding measurement jobs and related tasks.
