Later analog computers

In the first half of the 20th century, many scientific computing requires were met by increasingly sophisticated analog computers , which used a principal mechanical or electrical model of the problem as a time frame for computation . However, these were not programmable and normally lacked the versatility and accuracy of modern digital computers. [19]
The 1st modern analog computer was a tide-predicting machine , invented by simply Sir William Thomson in 1872. The differential analyser , a mechanical analog computer meant to solve differential equations by integration using wheel-and-disc mechanisms, was conceptualized throughout 1876 by James Thomson , the brother of the additional famous Lord Kelvin. [15]
The art of mechanical analog computing reached its zenith while using differential analyzer , built by H. L. Hazen and Vannevar Bush at MIT starting in 1927. This built on the mechanical integrators of James Thomson plus the torque amplifiers invented by H. W. Nieman. A dozen of such devices were built before their obsolescence became obvious.
By the 1950s the success of digital electronic computers had spelled the final for most analog computing machines, but analog computers remain available in some specialized applications such as education
