Professor Kenjiro Takayanagi started his research program in television at Hamamatsu Technical College (now Shizuoka University) in 1924. He transmitted an image of the Japanese character イ(i) on a cathode-ray tube on 25 December 1926 and broadcast video over an electronic television system in 1935. His work, patents, articles, and teaching helped lay the foundation for the rise of Japanese television and related industries to global leadership.

In January 1838, Samuel F. B. Morse and Alfred Vail first demonstrated publicly crucial elements of their telegraph system, using instruments that Vail had constructed during the previous months. Electrical pulses, transmitted through two miles of wire, caused an electromagnet to ink dots and dashes (grouped to represent letters and words) on a strip of paper. Commercialization began in 1844 when funding became available.

The discoveries of electricity in the latter half of the 18th Century, and its close connection with magnetism, were the products of earlier experiments, which in turn led to the invention of the electric telegraph. Telegraphy had connected the interior of the United States, and it also connected Europe together. However, connecting the Americas and Europe proved to be a challenge. Due to the electric current that ran through the cable lines, insulation and waterproofing was necessary.

On 8 March 1979, N.V. Philips' Gloeilampenfabrieken demonstrated for the international press a Compact Disc Audio Player. The demonstration showed that it is possible by using digital optical recording and playback to reproduce audio signals with superb stereo quality. This research at Philips established the technical standard for digital optical recording systems.
This event marked the start of the worldwide development of consumer digital optical recording and reproduction equipment, obtainable by the peoples of the world for a low price.

In 1954 three researchers at Bell Laboratories published the results of their discovery of the world’s first practical ‘photovoltaic’ (henceforth abbreviated by ‘PV’) cell which was capable of converting sunlight into electricity, first at 4% and later at 6% conversion-efficiency[1]. In 1959 Sharp Corporation began R&D of silicon monocrystal PV-cells, with mass production starting in 1963[2], and commercialized a variety of mono/multi-crystalline PV-cells for everything from satellites to lighthouses, and industrial applications to residential use[2].

Studies on the feasibility of building a hydro plant in the site were initiated in 1893. The increasing need for power that was cheaper and easily adapted to mine underground use drove the Lota coal mine company to develop a study of alternatives for this purpose. Engineer William E. Raby traveled to the United States and Europe to assess the use of electricity generation and transmission. The availability of the Chivilingo hydro resources arose as a better alternative to a steam plant.

A pioneer in the development of electrical science, Nicholas Joseph Callan was born on 22 December 1799 in Darver, Ireland. He started the priesthood at Navan Seminary, and continued his studies at St. Patrick’s College Maynooth, where he studied natural and experimental philosophy under Dr. Cornelius Denvir. After his ordination as priest in 1823, Callan pursued his doctorate in divinity in Rome, where he became acquainted with Galvani and Volta’s work in the study of electricity, and recognized the potential to put it to practical and commercial use with powerful batteries.

The Tokaido Shinkansen, the world's first inter-city, high-speed railway system, began operations on its route of over 500 kilometers between Tokyo and Osaka more than thirty years ago, in 1964. After its establishment, the Tokaido Shinkansen made a major contribution to Japan's rapid post-war economic growth as the country's principal transportation artery. Today (1997), more than two hundred and eighty Shinkansen trains operate between Tokyo and Osaka each day, with eleven departures an hour at peak times, and a daily ridership of more than 360,000 passengers.

The basic research tool at SLAC is an intense beam of electrons that have been accelerated by an electric field equivalent to 30 billion volts, making this the most powerful electron beam in the world.
The two-mile linear accelerator produces this field using high-power microwaves traveling through an evacuated waveguide. Electrons injected into one end of this pipe are continuously accelerated by this traveling field to very high energies.
