Question: I know that the answer to the question "how were floods able to be forecast?" is in "The tide-predicting machine invented by Sir William Thomson in 1872 was of great utility to navigation in shallow waters. It used a system of pulleys and wires to automatically calculate predicted tide levels for a set period at a particular location.". Can you tell me what it is?
Answer:
a system of pulleys and wires to automatically calculate predicted tide levels
