Popis:
People in the old times did a lot of hard work to bring this world to ease with their amazing inventions. We would like to mention several famous inventions which influeced this world.
The first invention was calendar which helps the world to measure time in a uniform way. The origin of the Calendar is tough to pin down. We know that many ancient peoples had their own calendars. Many primitive cultures used a four-day week, Central American peoples used a five day week; Assyrians had a six day week; pre-Christian Romans in the 1st century BC had weeks of eight days called nundinae.
As regards other inventions, we can mention pottery founded in China, plywood invented by Emmanuel Nobel, father of Alfred Nobel, and wheel. We don't know whom to thank for the wheel, but there would be no bicykles, no cars, buses or trains without it. And days of walking to get from one place to another.
This were famous inventions dated about 3000 BC.
