"The inhabitants of the Indus Valley Civilization (3000-1500 BC, Mature Period 2600-1900 BC) developed a sophisticated system of standardization (Mathematical System), using weights and measures, evident by the excavations made at the Indus valley sites. This technical standardization enabled gauging devices to be effectively used in angular measurement and measurement for construction.
Calibration was also found in measuring devices along with multiple subdivisions."
"The world's first recorded chemist is considered to be a woman named Tapputi, a perfume maker who was mentioned in a cuneiform tablet from the second millennium BC in Mesopotamia. She distilled flowers, oil, and calamus with other aromatics then filtered and put them back in the still several times.
Recently, archaeologists have uncovered what are believed to be the world's oldest perfumes in Pyrgos, Cyprus. The perfumes date back more than 4,000 years. The perfumes were discovered in an ancient perfumery. At least 60 stills, mixing bowls, funnels and perfume bottles were found in the 43,000-square-foot (4,000 m2) factory. Four of the perfumes have been re-created from residues found at the site."
