Bleeps and Blips to Rocket Ships: Great Inventions in Communications
Alannah Hegedus
Our fast-paced world of fax machines, digital cameras, and cell phones is possible because of the work of inventors who paved the way for modern communications.
Meet:
Reginald Fessenden, who thought of a continuous wireless signal when he noted the ripples resulting from a rock he tossed in a lake;
Alexander Graham Bell, who made his famous call ? "Mr. Watson, come here! I want you!" ? because he had spilled acid onto his trousers;
William Stephenson, inventor of the wirephoto, who was a spy during the Second World War.
From newsprint to fiber optics, discover ten great inventions in this fascinating book, and a great resource for science projects and science fairs:
? Make your own paper
? Create your own halftone image
? Make your own pinhole camera
? Make a telegraph
? Use Morse code
? Make a light fountain
