Ancient Inventions We Still Use Today While we are encouraged to use less paper or at least recycle it due to environmental concerns, Americans still use more than 2 trillion trees a year for paper and other products made of wood. Papermaking has been a practice since at least A.D. 105 , according to some Chinese records. But recent archeological evidence dates papermaking to two centuries earlier. However, although not made from wood per se, you can go back in time even further. Ancient Egyptians found a way of writing on papyrus paper around 3000 B.C. |

Mints: Poor dental health was common in ancient Egypt because of bread. They used stones to grind down the flour, a process that led to sand and small rocks remaining in the bread, and eventually making their way to people’s teeth, slowly rotting them. With no dentists yet, the Egyptians came up with a way to at least deal with the bad breath. The first mints were a mixture of frankincense, myrrh, cinnamon, and honey. Eventually, ancient Egyptians invented toothpaste. |

Odometers, which measure the distance traveled by a vehicle, are still among the most widely used instruments in the world. They used to be mechanical. A Roman architect and engineer, Vitruvius, is often credited with inventing the odometer in 15 B.C. What he designed was a large wheel in a small frame, similar to how a wheel is mounted on a wheelbarrow. “When it was pushed along the ground by hand it automatically dropped a pebble into a container at each revolution, giving a measure of the distance traveled. It was, in effect, the first odometer,” according to Encyclopedia Britannica. |

Cataract surgery: Some experts call the surgery to restore vision lost to cataracts one of the most successful medical treatments ever. Couching, the oldest method to treat a cataract, involved dislodging it out of the visual axis with a needle. The procedure, which restored limited but unfocused vision, dates back to 5th century B.C. The first modern cataract surgery to involve anesthesia took place in Paris in 1748. |

Door locks: The very first locks were technically knots made from ropes. Eventually people created locks made from wood and metal. The first types were documented in ancient Egypt some 6,000 years ago. A pin tumbler lock, made from wood, was attached to the door. A horizontal bolt, which could be opened with pins, slid into the post. The key was large, also made from wood, and looked like a toothbrush. |
