Tide-Predicting Machine No. 2, also known as Old Brass Brains, [1] was a special-purpose mechanical computer that uses gears, pulleys, chains, and other mechanical components to compute the height and time of high and low tides for specific locations. The machine can perform tide calculations much faster than a person could do with pencil and ...
The first tide predicting machine (TPM) was built in 1872 by the Légé Engineering Company. [11] A model of it was exhibited at the British Association meeting in 1873 [12] (for computing 8 tidal components), followed in 1875-76 by a machine on a slightly larger scale (for computing 10 tidal components), was designed by Sir William Thomson (who later became Lord Kelvin). [13]
Joining the newly founded Tidal Institute in Liverpool in 1919 he produced tide tables, and was involved in designing tide-predicting machines. He was elected a Fellow of the Royal Society . During WWII he calculated the best combination of full moon and ideal tidal conditions for D-Day on 6 June 1944.

Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
