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.
In 1450 Gutenberg borrowed a considerable sum of money from Johann Fust, a wealthy businessman and moneylender. The loan funded the construction of printing equipment for another workshop, which was large enough to accommodate the inventorâs next and most ambitious project, the 42-line Bible. Gutenberg viewed printing as a craft, not as a replacement for handwriting.
