Antud teose kvaliteet oli niivõrd hea, et väga mitmed inimesed publiku seast kartsid, et rong sõidab nendest kohe üle. Oma osa 3D kino arengule on andnud ka televiisori leiutaja John Logie Baird, kes pani aluse 3D-televisioonile mitmete elektomehaaniliste ja katoodtorude tehnikate kasutamise läbi. 1928. aastal esitles ta steroskoopia edastamist televisioonis, mille kohta ilmus samal aastal ajalehes Radio News ka põhjalik artikkel „How Stereoscopic Television is Shown“. Transmitterseade koosnes plaadist, mille ühele poolümbermõõdule oli kinnitatud üks spiraal ning teine plaadi äärest neli tolli sissepoole (antud pikkus vastab inimese tavapärasele silmade vahemaale). Ketta taga asub asub intensiivse valguse allikas, ketta ees aga kindla asetusega objektiiv nii, et kujutis pööratakse tugeva valguse abil ümber. Kokkuleppeliselt on mõlema
in a remote region near the town of Kushequa in north-west Figure 14 Portage Viaduct (1852) (USA), Pennsylvania (USA), was originally constriucted in 1882 by the photographed shortly after it was completed for New York & Erie Railroad to service lumber mills in this lush, this stereoscopic view, was the wonder of visiting forested corner of Pennsylvania. The present structure, 302ft engineers, who used it frequently as an example of (92m) high and 2052ft (625m) long, replaced the original when American timber bridge construction technology in Erie officials decided that the bridge could no longer support their
20th-century cryptanalysts who tried to break it down! To this day the Navy uses it. This is a remarkable longevity. So important is his system that it confers upon Jefferson the title of Father of American Cryptography. [Codebreakers 117.jpg] Charles Wheatstone had a remarkably fertile mind. He constructed an electric telegraph before Morse did, invented the concertina, improved the dynamo, studied underwater telegraphy, produced some of the first stereoscopic drawings, published half a dozen papers on acoustics, discussed phonetics and hypothetical speaking machines in print, conducted numerous electrical experiments, and popularized a method for the extremely accurate measurement of electrical resistance now in frequent use and called the "Wheatstone bridge." His work was highly enough regarded for him to be elected a fellow of the Royal Society and to be knighted. He was nominally professor of experimental
