Cooke and Wheatstone's electric telegraphThe more anecdotal version told in Göttingen observatory is that the first message was sent to notify Weber that the observatory's servant was on the way to the institute of physics, and just read " Michelmann kommt " (" Michelmann is on his way "), possibly as a test who would arrive first.

The history of linear electric motors can be traced back at least as far as the 1840s, to the work of Charles Wheatstone at King's College in London, but Wheatstone's model was too inefficient to be practical.

Cooke and Wheatstone's very first telegraph was tested on July 4, 1837, nestled in a newly-erected carriage shed of the London and Birmingham Railway at Camden Town in north London.

However, Cooke and Wheatstone's multiple-wire signaling method would be overtaken by Morse's superior method within a few years.

His original work dealt, among other things, with Wheatstone's sound-figures, the characteristic notes of the different vowels, a manometric flame apparatus, a vibration microscope, among others ; but perhaps the most important of his researches are those devoted to the phenomena produced by the interference of two tones, in which he disputed the views of Helmholtz as to the existence of summation and difference tones.

Hermann also played back vowel recordings made with the Edison phonograph at different speeds in order to test Willis ' and Wheatstone's theories of vowel production.

Hermann also played back vowel recordings made with the Edison phonograph at different speeds to distinguish between Willis ' and Wheatstone's theories of vowel production.

Wheatstone invented the stereoscope, an optical device ( in Wheatstone's case using mirrors ) to present different images to the two eyes.

Although Wheatstone's discovery of stereopsis supported fusion theory, he still had to account for binocular rivalry.

Sources differ whether German inventor Carl Friedrich Uhlig created his first concertina after seeing Charles Wheatstone's instrument of the same name, or whether the two men invented their instruments concurrently and independently.

Charles Wheatstone's prismatic pseudoscope.

Wheatstone's paper stimulated the investigation of binocular vision and many variations of pseudoscopes were created, chief types being the mirror or the prismatic.

In 1853 the American scientist John Leonard Riddell ( 1807-1865 ) devised his binocular microscope, which contained the essentials of Wheatstone's pseudoscope.

There was only one way to accomplish this: by design, by drawing diagrams and sketches in which he probed the remotest corner of his mind for creative ideas to carry his concept.

Bicycle gear-sets he had once used as the basis of the design for the Camden Cycly Company plant hung on a rope in one corner, and over his desk, next to several old and dusty hats, was a clean pair of roller skates which he occasionally used up and down in front of his house.

Like many others, he had to work hard, long hours in a struggling family business which, though it was allied to art of a kind -- the design and production of engraved seals -- bore no relation to the painting of pictures.

With greater investments in plant facilities, with automation growing, you can't switch around, either in volume or in product design, as much as was formerly possible -- or at least not as economically.

At the end of its letter was the information that applicants for this position `` must also be prepared to teach costume design and advertising art ''.

It was shown that by proper anode design the net energy loss of the arc to the anode could be reduced to approximately 15% of the total arc energy.

Michelangelo was the most distinguished of several noted architects who helped design it.

); its design was planned by the government of the day ; and it places individual letters in syllable clusters with equal dimensions, in the same way as Chinese characters, to allow for mixed-script writing ( one syllable always takes up one type-space no matter how many letters get stacked into building that one sound-block ).

The site of the colony's capital was surveyed and laid out by Colonel William Light, the first Surveyor-General of South Australia, through the design made by the architect George Strickland Kingston.

William Baker Ashton was appointed Governor of the temporary goal in 1839, and in 1840 George Strickland Kingston was commissioned to design Adelaide's new Gaol.

Throughout ancient and medieval history, most architectural design and construction was carried out by artisans, such as stone masons and carpenters, rising to the role of master builder.

It was first described in 1837 as the successor to Babbage's Difference Engine, a design for a mechanical computer.

During this project he realized that a much more general design, the Analytical Engine, was possible.

It was a controversial design at the time for the bold forms of the undulating stone facade and wrought iron decoration of the balconies and windows, designed largely by Josep Maria Jujol, who also created some of the plaster ceilings.

The design by Gaudi was not followed in some aspects.

It replaces the " sheaves of wheat " design, and was minted until 2008.

The mechanical and logic design was worked out by Dr. Atanasoff over the next year.

The design, development and construction of the center was conducted by Kurt H. Debus, a member of Dr. Wernher von Braun's original V-2 rocket engineering team.

Although he was in charge of the project for the papal villa, the Villa Pamphili, now Villa Doria Pamphili, outside the Porta San Pancrazio in Rome, he may have had professional guidance on the design of the casino from the architect / engineer Girolamo Rainaldi and help with supervising its construction from his assistant Giovanni Francesco Grimaldi.

But the design of the idealized free library was the subject of prolonged and heated debate.

Commodore's design choice to remain with the 68000 architecture ensured that code was backward-compatible across the Amiga line.

Thus, the Turun Sanomat Building first heralded Aalto's move towards modernism, and this was then carried forward both in the Paimio Sanatorium and in the on-going design for the library.

It was Maire Gullichsen who acted as the main client, and she worked closely not only with Alvar but also Aino Aalto on the design, inspiring them to be more daring in their work.

The original design was to include a private art gallery, but this was never built.

Leonardo's vision was resurrected in 2001 when a smaller bridge based on his design was constructed in Norway.

The two Addams Family movies in 1991 and 1993, along with the second animated television series in 1992, resurrected the mansion's original exterior design from the Charles Addams cartoons.

VW resurrected the basic Kübelwagen design several decades after the war as the 1969 Type 181, developed for the German Federal Armed Forces and later also produced for the civilian market known as " Thing " in the US, " Trekker " in the UK and " Safari " in Mexico.

The vision was resurrected in 2001, when a small footbridge of Leonardo's design was constructed near Ås in Norway.

Late in the war, the design was resurrected for consideration as a selbstopfer ( suicide weapon or kamikaze ) aircraft, but was judged unsuitable even for this purpose.

Although the TRF design heralds from the early years of radio and has been largely superseded by superheterodyne and other circuits, it was ' resurrected ' in 1972 in silicon as the ZN414 TRF radio integrated circuit from Ferranti, thus affording the design a new lease of life in hobbyist radio projects, kits and some commercial products.

However, some modern builders of Selmer-style instruments ( including Canadian luthier Michael Dunn, who uses his own design ) have resurrected the feature.

The full-extent and design of the new Titans base was never properly developed unfortunately, as soon after the team was assembled, they were attacked by a resurrected Trigon.

The original design started in 1919 but lapsed until resurrected in 1927 as a partner-piece for a new 155 mm gun.
