To all those who open this notebook, So many inventions have changed the way we live. Some of them have even changed the world! Indispensable, practical, funny, serious and occasionally tasty, each of these inventions has a story that I find captivating! Many curious young readers think they’re interesting, too, so I’ve gathered all the questions about inventions that appeared during prehistoric and ancient times (between the time humans first appeared 5 million years ago and the year 476). Who invented the wheel? When was ice cream invented? How long has paper been around? I’ve answered these questions and many others in this notebook, with the help of simple diagrams, photos and other illustrations. So keep asking questions and let your imagination run wild. Who knows? You may be one of tomorrow ’s inventors… Happy reading! Professor Genius

Dear Professor, Can you tell me who invented fire? Thank you very much.
Emily, age 7
Dear Emily, That’s a very interesting question! As a matter of fact, fire is not really an invention. To help you understand why, Emily, let me explain the difference between an “invention” and a “discovery..” An invention is something new that is created by a human being. It is something that did not exist before. It can be an object, a tool or material. A discovery, on the other hand, is a thing or a phenomenon that is seen or understood for the first time, but that already existed in nature. And so, dear Emily, fire is a discovery and not an invention.

On the other hand, the many different ways to make a fire are inventions. (Think of a lighter or matches, for example.) But let’s get back to your question. One of the oldest clues indicating that humans used fire was found in a cave in South Africa. Fossilized bones, about 1.5 million years old, showed that people at that time had cooked an antelope. It is believed, thanks to bushfires lit by lightning, that prehistoric humans managed to get hold of a flame and carry it back to their encampment. How did they do it? No one really knows for sure. You could imagine a brave member of the tribe approaching this monstrous fire to light a stick of wood. The tribe probably watched over the flame, day and night. It was important that the fire not go out because they did not yet know how to make it themselves! It was only a million years later that humans invented the

first ways of making fire. Without a doubt, Emily, this discovery changed people’s lives. From this moment on, they could use fire to frighten off wild animals and to cook the meat and vegetables they ate. Also, thanks to the light from the flame, they could make homes in caves that had once been too dark to live in. It isn’t a big thing for us, who are used to our comforts, but at the time, it was quite a revolution! Best regards, Professor Genius

Subject: First invention Date: September 15, 2006 To: Professor Genius
Dear Professor Genius, Do you know what the first thing ever to be invented was? If you do, please tell me :) Take care, Raymond, age 7
My dear Raymond, The oldest known object to have been invented is a tool. As a matter of fact, it was a chopper—a stone carved with the help of another stone to make it sharp. Its inventor was one of the first humans, called ”Homo habilis.” The chopper was very practical! It was used to cut up the meat of animals (perhaps antelopes or elephants), carve wood or crack nutshells. The oldest of these carved stones were found in Tanzania, a country in East Africa. They are more than 2.5 million years old! Over time, improvements were made to this tool. After choppers, people made Chopper 8
