Some Important Inventions



An invention is a new thing, way of doing something, composition or process. It may be an improvement upon a machine or product or a new process for creating an object or a result. An invention that achieves a new function or result may be a breakthrough. Such works are special and may not be obvious to other people, even those working in the same field. An inventor may be taking a big step in success or failure.

 Some Amazing Inventions:

 Flight


The History of Human-Powered Flight is an impressive interactive timeline from NPR.

How Do Things Fly?
A great interactive site from the Smithsonian. It is THE site to learn about anything related to flight. You can design and virtually fly your own plane, and you can even design and print-out your own paper airplane.

Printing
The first printing on paper was done in China as far back as 200 CE. This used woodblocks, or blocks of wood with letters carved in reverse on them.

The big change came in printing in around 1440 when a man named Johannes Gutenberg made a winepress into a printing press.




Internet
The Internet was invented in stages, not all at once. It took 40 years to invent the Internet. And it is still being invented today.

Toilet
The Toilet is one of the most important inventions of all time. Without it disease and sickness, not to mention late night trips to the outhouse and lots of bad smells, would be more common today than they are.

But what if Hicc

George's Marvellous Medicine

Image
Rik Mayall was an explosion of kinetic energy which manifested itself in a unique style of comedy that alienated those who feared life and delighted everyone else. Roald Dahl, meanwhile, was a writer of children's books who managed to conjure up worlds which were highly relatable yet, at the same time, coloured fantastically with surreal and grotesque narratives. And, in January 1986, these two worlds collided when Mayall delivered a one man performance of Roald Dahl's 1981 novel George's Marvellous Medicine for BBC1's Jackanory.

Telling a Story with Moving Images

Image
Animation is a process used to create motion pictures through the combination of still images (e.g., digital graphics, photographs of drawings, photographs of objects, etc.) which, when played in sequence, create the illusion of movement. All television cartoons, for example, are animations, and are made up of thousands of still images (drawn by hand or on a computer) that are played sequentially, along with a soundtrack, to tell a story. Directed by Alan Barillaro and produced by Marc Sondheimer, “Piper,” a short from Pixar Animation Studios, tells the story of a hungry sandpiper hatchling who ventures from her nest for the first time to dig for food by the shoreline. The only problem is, the food is buried beneath the sand where scary waves roll up onto the shore. “Piper” debuted in theaters worldwide with “Finding Dory” in 2016. Director’s Statement  “Piper began as a test to try and craft develop animation tools that would provide greater flexibility to for artists. As the
