Looms, yes. British, no. French, mais oui.
Jacquard et al, IIRC.

i know its thread drift, but interesting piece came up today:

Memristors in silicon promising for dense, fast memory

interesting futures there i think.

He demonstrated the world's first colour transmission on 3 July 1928, using scanning discs at the transmitting and receiving ends with three spirals of apertures, each spiral with a filter of a different primary colour; and three light sources at the receiving end, with a commutator to alternate their illumination. That same year he also demonstrated stereoscopic television.

colour tv in 1928!!!

In 1941, he patented and demonstrated a system of three-dimensional television at a definition of 500 lines. On 16 August 1944, he gave the world's first demonstration of a fully electronic colour television display. His 600-line colour system used triple interlacing, using six scans to build each picture

In 1943, the Hankey Committee was appointed to oversee the resumption of television broadcasts after the war. Baird persuaded them to make plans to adopt his proposed 1000-line Telechrome electronic colour system as the new post-war broadcast standard. The picture quality on this system would have been comparable to today's HDTV. The Hankey Committee's plan lost all momentum partly due to the challenges of postwar reconstruction.

hdtv in 1943 !!!

farnsworth who? :)

Very interesting, thanks 303.

I'd credit Farnsworth with the theory that led to the CRT and modern television. Don't get me wrong, there were several scientists working on the same idea, but the theory of value was from Farnsworth. Baird would owe Farnsworth for his full electronic color television via use of Farnsworth's pre-existing theory and patent. Baird also wasn't the "inventor" as it had already been proposed by Paul Nipkow 40 years earlier.

Really good analysis here:
http://49chevy.blogs.com/farnovision/20 ... rnswo.html
Saying Baird invented television is sorta like saying that the first guy who hooked a horse up to a cart invented the motor car. Or that the first person who put a match to a candle invented the light-bulb.

Farnsworth's contribution was seminal: it removed all the mechanical contrivances, and demonstrated a mastery of quantum physics previously unknown. I like to call it "the leap from parts to particles." I find Abramson's assessment of a "blob of light" particularly laughable. That "blob of light" proved a principal, and had Abramson's own patrons -- Zworykin, RCA -- clamoring for the patent rights to that principal.

Well, all is question of interpretation.
Who discovered America? Native Americans, Leif Erickson or Christopher Columbus? For all practical purposes it was Columbus although he was the only one of the three that never landed on the continent itself.
Did you know that ancient Greeks invented jet engine in the 3rd Century BC and maybe even earlier, but this is the first historical record? It doesn't matter, for all practical purposes it was invented during World War II.
Did you know that is likely that an ancient Roman most likely discovered Aluminum? This is a particularly interesting story related by Pilny the Elder:
One day a goldsmith in Rome was allowed to show the Emperor Tiberius a dinner plate of a new metal. The plate was very light, and almost as bright as silver. The goldsmith told the Emperor that he had made the metal from plain clay. He also assured the Emperor that only he, himself, and the Gods knew how to produce this metal from clay. The Emperor became very interested, and as a financial expert he was also a little concerned. The Emperor felt immediately, however, that all his treasures of gold and silver would decline in value if people started to produce this bright metal of clay. Therefore, instead of giving the goldsmith the regard expected, he ordered him to be beheaded.
We had to wait several centuries before it was rediscovered.
Today people don't get beheaded, they just get ridiculed.

Well, Wikipedia is generally acknowledged as UN biased (true, some subjects are highjacked, but not many) and
Wikipedia wrote:In 1927, Philo Farnsworth made the world's first working television system with electronic scanning of both the pickup and display devices, which he first demonstrated to the press on 1 September 1928.
True, there had been a lot of electro-mechanical systems but it took an all electronic system to become viable. Farnsworth invented television as we know it today; ok, as we knew it a decade or two ago when it was analog! ;)

In early 1923, and in poor health, Baird moved to 21 Linton Crescent, Hastings, on the south coast of England and later rented a workshop in Queen's Arcade in the town. Baird built what was to become the world's first working television set using items including an old hatbox and a pair of scissors, some darning needles, a few bicycle light lenses, a used tea chest, and sealing wax and glue that he purchased.[10] In February 1924, he demonstrated to the Radio Times that a semi-mechanical analogue television system was possible by transmitting moving silhouette images. In July of the same year, he received a 1000-volt electric shock, but survived with only a burnt hand. His landlord, a Mr Tree, asked him to quit his workshop and he moved to upstairs rooms in Soho, London, where he made a technical breakthrough. Baird gave the first public demonstration of moving silhouette images by television at Selfridges department store in London in a three-week series of demonstrations beginning on 25 March 1925.

In his laboratory on 2 October 1925, Baird successfully transmitted the first television picture with a greyscale image: the head of a ventriloquist's dummy nicknamed "Stooky Bill" in a 30-line vertically scanned image, at five pictures per second

think most people class a picture on a screen recorded by something else, television, whether mechanical or electronic , (in fact mechanical is even more amazing it could be argued) and 1923 is earlier than 1927 :)

"Amazing" but not viable. A toy, not a viable mass communication system. Baird invented a neat toy that went precisely nowhere. Congrats to him. :roll:

Next, we'll have a Canadian telling us how great the obsolete before it was produced Arrow was.

It was a wonderful design for 1952, cancelled in 1959.

Self-fulfilling prophecy if I ever saw one.

I'm afraid you're going to have to back that up.

Are VC's more interested in social media than science and technology?

"Centers of innovation require investors funding smart people working on interesting things - and they invest in those they believe will make their funds the most money. And for Silicon Valley the investor flight to social media marks the beginning of the end of the era of venture capital-backed big ideas in science and technology."
