From Sumerians and Babylonians we learned to use the sexagesimal system, based on number 60 (for instance, 1 hour = 60 minutes). They invented the first writing system, cuneiform writings on clay tablets to facilitate trade in Mesopotamia. They also invented beer, which facilitated mobilization of Sumerian laborers in public building projects. Subsequently, Egyptians imitated their methods in building the pyramids. Beer and bread were often ratioined. Both Chinese and Sumerians used the same sexagesimal time (24 hours, 60 minutes, etc.) This may have been due to their trade from ancient times. (Arabian horses were well known, and Babylonian language was the trade language in western Asia since the time of King Akhenaton.) The following tables eloquently testify their contributions to human civilization. Their descendants are modern Iraqis and Iranians.

The history of the alphabet starts in ancient Egypt. The first pure alphabets (properly, "abjads", mapping single symbols to single phonemes, but not necessarily each phoneme to a symbol) emerged around 2000 BC in Ancient Egypt, as a representation of language developed by Semitic workers in Egypt, but by then alphabetic principles had already been inculcated into Egyptian hieroglyphs for a millennium (see Middle Bronze Age alphabets). Most other alphabets in the world today either descended from this one discovery, or were directly inspired by its design, including the Phoenician alphabet and the Greek alphabet.

Google Glass may seem like a novelty right now but the wearable gadget could soon be saving some companies millions of dollars per year. Smartglasses will be particularly useful for workers who need to use both hands to complete complex tasks, such as c onducting surgery or fixing a car. Here, a woman tests a pair of Google glasses equiped with LIS (Italian Sign Language - 'Linguaggio Italiano dei Segni') capabilities.
