Periodic table
Russian chemistry professor Dmitri Mendeleev and German chemist Julius Lothar Meyer independently published their periodic tables in 1869 and 1870, respectively. Mendeleev's table was his first published version; that of Meyer was an expanded version of his (Meyer's) table of 1864. They both constructed their tables by listing the elements in rows or columns in order of atomic weight and starting a new row or column when the characteristics of the elements began to repeat.
Edgar James Banks
Banks is credited with the discovery of the Plimpton 322 tablet in Southern Iraq. It is believed to be the world’s oldest trigonometric table, predating Hipparchus by around 1000 years and, using base 60, also the most accurate trigonometric table, avoiding inexact numbers. It thus displayed knowledge of the Pythagorean theorem long before the birth of Pythagoras himself. The ancient cuneiform tablet was sold to the New York publisher George Arthur Plimpton, reportedly for $10. It was housed in Plimpton's private collection before being donated to Columbia University upon Plimpton's death. The artifact, now famously known as Plimpton 322 (denoting that it is the 322nd item in the catalog), has provided great insight into the Babylonian era mathematics.
