  • tea towel

    Towels for drying dishes and other culinary items

  • teaching aid

    A tool used by teachers, facilitators, or tutors to help learners improve reading and other skills,or to illustrate or reinforce a skill, fact, or idea. They can often combat anxiety or boredom, as many teaching aids are like games.

  • teapot

  • telegram

    Messages sent by telegraph.

  • telegrams

  • telegraph

    Any of numerous types of devices or systems that allow the transmission of information by coded signal over a distance. Many telegraphic systems have been used over the centuries, but the term most often refers to the electric telegraph, which was developed in the mid-19th century and was the principal means of transmitting printed information by wire or radio wave for over a century. It consisted of a transmitting or sending instrument and a distant receiving instrument connected by a conducting wire or other communications channel.

  • telegraph peripheral

    Components of wireless telegraphy sets, for example, printers, Morse keys, etc

  • telephone

    Instrument, apparatus, or device that convey or reproduce sounds at a distance, especially such devices in which the human voice is transmitted as by wire, satellite, or via base-station antennas as short-wave analog or digital signals. The term was used as early as the 18th century to refer to string phones (cups joined by a string), but the modern device is attributed to Alexander Graham Bell, who patented it in March 1876. That original telephones worked on the principle that sounds of speech are complex vibrations in air, which can be transferrable to solid bodies and in electrical impulses in conducting metals.

  • telescope

    optical instruments using mirrors, lenses or both, which produces a magnified image of distant view. There are three main types of telescope; namely refracting (dioptric), reflecting (catoptric) and the combination of the former types known as catadioptric.

  • telescope - Cassegrain

    A type of reflecting telescope with a parabolic primary mirror, and a hyperbolic secondary mirror that reflects the light back down through a hole in the primary. Folding the optics makes this a compact design.

  • telescope - catadioptric

    Type of telescope, an optical instrument that produces an enlarged image of distant views, which uses both mirrors and lenses to provide magnification.

  • telescope - Dall Kirkham

    A type of reflecting cassegrain telescope that uses a concave elliptical primary mirror and a convex spherical secondary. Created by Horace Dall in 1928 it took its name from an article published in Scientific American in 1930, following discussion between amateur astronomer Allan Kirkham and Albert G.
