How do they work? Apps can let your phone or tablet do almost anything that the programmers can imagine, within the technical limitations of the device. This means that you can turn your phone into a remote control for a toy helicopter, your tablet into a turbo-charged drawing pad, and much else besides. Since the release of Apple's iPhone, smartphones have become powerful enough to perform more than just the features that were built into the phone.
Johannes Gutenberg was a German goldsmith and inventor best known for the Gutenberg press, an innovative printing machine that used movable type. Gutenberg was born between 1394 and 1400 and died in 1468. In 1438, Gutenberg began a business arrangement with Andreas Dritzehn, who funded his experiments in printing. In 1450, Gutenberg began a second arrangement with German businessman Johannes Fust.
Johannes Gutenberg got rid of the woodblock ideas and tried to work with metal. He decided it worked very well and was completing the first book ever printed by his new invention, which was movable type. The first book was the Bible, which was printed in Latin. His invention was called the printing press. Soon enough the blacksmith that Johannes Gutenberg was working for lost faith in him and decided to take him to court. The judge favored with Fust, so everything Gutenberg worked on and owned belonged to Fust. Johannes Gutenberg ended up dying in Mainz, Germany in 1468.
