3 days ago · This concept inspired the use of the term in research, art and discovery. In 1939, John Vincent Atanasoff and Clifford Berry created the Atanasoff-Berry computer (ABC), and in 1949, Edmund Berkely published “Great Minds: Or Machines That Think”, in which he highlighted how machines can handle large amounts of information at great speed.
2 days ago · Calculating devices took a different turn when John Napier, a Scottish mathematician, published his discovery of logarithms in 1614. As any person can attest , adding two 10-digit numbers is much simpler than multiplying them together, and the transformation of a multiplication problem into an addition problem is exactly what logarithms enable.
