The Facts On File Algebra Handbook

Newton’s work in the field. A bitter dispute follows. As

president of the organization, Newton requests an

investigation, then anonymously writes the society’s official

stance stating that Newton is the true inventor.

1713 lJAKOB BERNOULLI’s book Ars conjectandiis published, eight

years after his death, stating the properties of the Bernoulli

numbers.

lROGER COTEScompletes his work editing Newton’s second

edition of Principia.

1714 lGABRIEL DANIEL FAHRENHEITinvents the first mercury

thermometer.

1724 lFahrenheit introduces a new temperature scale to measure

the freezing and boiling points of liquids in his mercury

thermometer, called the Fahrenheit scale.

1727 lEuler introduces the symbol eto represent the BASEof

natural logs.

1734 lFrench scientist Pierre Bouguer introduces the symbols for

“greater than or equal to” and “less than or equal to.”

lEuler invents f(x)as the notation of a function.

1742 lGABRIEL CRAMERpublishes Johann Bernoulli’s Complete

Worksin a four-volume set. Bernoulli insisted that the work

could only be published by Cramer.

lANDERS CELSIUSdevelops the centigrade scale, also called

the Celsius scale, to measure temperature.

lCHRISTIAN GOLDBACHwrites a letter to Euler in which he

states his CONJECTUREthat every even INTEGERgreater than

two is the SUMof two primes. This becomes known as

Goldbach’s Conjecture, and will remain one of the greatest

unproved mathematical problems of all time.

1744 lJakob Bernoulli’s Worksis published by Gabriel Cramer.
