    Mathematicians attempt to create better ways of computing

    In the fifteenth and sixteenth centuries mathematicians worked to find more powerful methods of computing and better notations for representing concepts.

  • John Napier

    Napier published his discovery with the purpose of multiplying quantities that were known as sines at the time.

  • Napier's Bones

    Napier develops a calculating tools, sticks that are based off of the lattice method of multiplication.

  • Joost Burgi

    The Swedish mathematician created the first tables relating arithmetic and geometric sequences.

  • Development of the slide rule

    William Oughtred places two logarithmic scales together, allowing him to multiply and divide directly. He is credited with the invention of the slide rule.

  • Henry Briggs

    Henry Briggs, assistant to Napier, published a table of logarithms calculated to 14 decimal places for 30,000 values [1-20,000 and 90,000 to 100,000].

  • Adriaan Vlacq

    Published a table for 1-100,000 to ten decimal places.
