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.
Synopsis. Johannes Gutenberg was born circa 1395, in Mainz, Germany. He started experimenting with printing by 1438. In 1450 Gutenberg obtained backing from the financier Johann Fust, whose impatience and other factors led to Gutenberg's loss of his establishment to Fust several years later.
