when was the first potter's wheel invented
Potter's wheel The earliest forms of the potter's wheel (called tourneys or slow wheels) were probably developed as an extension to this procedure. Tournettes, in use around 4500Â BC in the Near East, were turned slowly by hand or by foot while coiling a pot. Only a small range of vessels were fashioned on the tournette, suggesting that it was used by a limited number of potters.[1] The introduction of the slow wheel increased the efficiency of hand-powered pottery production.
History of tablet computers The tablet computer and the associated special operating software is an example of pen computing technology, and the development of tablets has deep historical roots. The first patent for a system that recognized handwritten characters by analyzing the handwriting motion was granted in 1914.[2] The first publicly demonstrated system using a tablet and handwriting text recognition instead of a keyboard for working with a modern digital computer dates to 1956.[3]
