Knowing who invented zero will hold the keys to its original objective and its use today. The early Babylonian mathematics was without a spot for zero and instead used other symbols as the placeholders that worked effectively to make the digit relevance of the arithmetic. The ancient Greeks had been content with out zero and they did not find sense at all in naming something that basically did not exist. Giving value to something that had no value did not matter a great deal to them. However as different specialists and scholars emerged in many societies, zero was invented and became recognized as an essential number and digit.
Science likes a good clean story where all the evidence lines up; new puzzle pieces are continuously added and archaeologists sometimes have to resort to guesswork and modify theories with new additions. The Olmecs are assumed to be the first advanced civilization in Mesoamerica, but the Western Mexico shaft tomb tradition contains evidence that there may have been cultures which pre-date them by a number of centuries. The most famous theory can nonetheless be wrong, and all it takes is totally new evidence.
During their time, the Mayans developed a calendar known as the Maya Calendar. This Calendar is said to be one of the most documented and best understood calendars of our time. With predictions made from this calendar, people looked forward to the future hoping that the calendar would prove itself right. These predictions came from the Mayan peoples themselves by studying the constellations at night time sky. The Calendar is dated as far as the year 2012. From this point on, some people believe it could cause the end of the world. Others are still feeling skeptical about this impetuous prediction.
In 1519, Hernan Cortes, who conquered the Aztecs, discovered a chocolate ritual where 50 cups were brimming with beans in storehouses a day and saw that cacao was used as currency. After the Aztecs were conquered, the Spanish adapted the culture of the Aztecs and began to drink hot chocolate. In the 17th century, the Spanish princess Maria Theresa brought the cacao beans to the French court where she married King Louis XIV, and chocolate became a delightful treat in European society.
