Logarithmetica Brittanica - 1952 2 of 29
Front page of Professor Alexander J Thompson's 20-figure log tables published in 1952.
The calculations to produce these tables started in 1924 (using mechanical hand calculators) as a project to celebrate the tercentenary of Briggs' tables.
By the time the calculations were completed in 1952, it could all have been done in a matter of minutes on the earliest computers, which has just been developed!
