Transcript of Discovery of Light and Sound

Discovery of Light and Sound
15th Century
During the 15th century the sound of full triads became common, and towards the end of the 16th century the system of church modes began to break down entirely, giving way to the functional tonality which was to dominate western art music for the next three centuries. Polyphony became increasingly elaborate throughout the 14th century, with highly independent voices: the beginning of the 15th century showed simplification, with the voices often striving for smoothness. This was possible because of a greatly increased vocal range in music – in the Middle Ages, the narrow range made necessary frequent crossing of parts, thus requiring a greater contrast between them.

Towards the end of the 15th century, polyphonic sacred music (as exemplified in the masses ofJohannes Ockeghem and Jacob Obrecht) had once again become more complex, in a manner that can perhaps be seen as correlating to the stunning detail in the painting at the time.
Sound recording and reproduction is an electrical or mechanical inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. At 15th Century it was discovered. In the 14th century, Flanders introduced a mechanical bell-ringer controlled by a rotating cylinder. Similar designs appeared in barrel organs (15th century), musical clocks (1598), and etc……….

15th-Century ruins discovered during construction of Apple's new madrid flagship the light rail transit. The light was also discovered the curvature of light through atmospheric refraction at 15th Century.
16th Century
• All light rays refract and converge on one point at retina
• Speed of light is measured here.
• Light moves through luminiferous ether.
• White light composed of all colors, color is light.
• The first telescope was invented by Hans Lippershey.
• [LATERNA MAGICA], the earliest form of projection device was invented by Kircher.
• Grimaldi, in Italy, discovered optical diffraction and observed its periodic nature. {1ST DEFRACTION}
• Huygens (hoi'gens) was a Dutch scientist, who thought that light consisted of waves, not particles, as did [NEWTON]. Both theories had strong arguments in their favor.
• Newton was first to formulate the corpuscular theory of light. Newton said that luminous bodies radiate energy in particles or corpuscles, and that these particles are ejected in straight lines.
• Color is an electromagnetic wave phenomenon. It is a sensation produced when light stimulates the retina of the eye, and the brain interprets this sensation as 'color'.

• In 1678 [HUYGENS] discovered the polarization of light by double refraction in calcite. Polarized light is a special type of light. It occurs in nature and can also be manmade. Ordinary light consists of a mixture of waves vibrating in all directions perpendicular to its line of propagation (or travel). Polarized light consists of the electric or magnetic waves all confined to one plane. Polarized light can be obtained by reflection (depend on the angle of incidence) and it can also be obtained by double refraction in certain crystals, such as calcite.
• Over the centuries, many efforts have been made to compare color to sound and to link the two media into a single systematic language. The French Jesuit, Louis Bertrand Castel claimed that he was inspired by Kircher, and was the first to create an actual [COLOR ORGAN]. Castel called his device 'Clavessin Oculaire'. The device consisted of a remodeled harpsichord with a keyboard. Padre gave his first recital in Paris on December 21, 1734.
1. Marin Mersenne - (1640) first measured the speed of sound in air.
2. Robert Boyle - (1660) discovered that sound waves must travel in a medium.
3. Sir Isaac Newton - (late 1660's) formulated a relationship between the speed of sound in a medium and the density and compressibility in a medium.

Domestic activities were greatly restricted after sunset, when the only sources of light were the fire in the hearth and candles or rushlights. The light from rushlights and tallow candles was poor and they gave off an unpleasant smell. Beeswax candles gave a better light and were less smelly, but they were also much more expensive and tended to be reserved for special occasions.
17th Century
'A woman reading by Candle-light' by Frans van Mieris the elder, c.1665; black chalk on vellum.
18th Century
• In the latter part of the century, the "floating oil wick lamp" was introduced in France, quickly replaced by a device known as a glass chimney. The glass chimney is essentially an oil lamp enclosed in glass, which makes the flame more stable and less likely to flicker. The light created by the glass chimney was much brighter than regular candlelight. Additionally, the color of the glass could be changed to create different moods in lighting.
Limelight
• Prior to the use of electricity, the majority of theatres depended upon gaslight for illumination. However gas was expensive, difficult to control and therefore required constant attention. The first "spotlight" was known as limelight and was introduced by British engineer Thomas Drummond. The intensity of the spotlight is created by heating calcium carbonate combined with an oxygen and hydrogen flame. This effect provided a much more natural-looking type of light and was also able to be focused to create a specific "spot" or pool of light onstage. It was also helpful in creating stage illusions for the sun and the moon.
Telephone
• The telephone was invented in 1876 by Scotsman Alexander Graham Bell. He originally dubbed it the "electrical speech machine," but thankfully this was changed. Bell opened the very first telephone exchange in New Haven in 1878. Over the years, the telephone has been adapted, and today almost everyone carries a cell phone with them. In addition, without the telephone, we wouldn't have the Internet, as it relies on phone lines to exchange information.

Phonograph
• Thomas Edison invented the phonograph in 1877 while he was working on a telephone transmission device. It was a precursor to the record player, but played cylinders, rather than vinyl records. The phonograph could both record and play back sound. Although this doesn't seem too impressive today, it was astounding to people in the 19th century. Without the invention of the phonograph, we wouldn't have any recorded music, so we would never have known CDs and MP3s.

19th Century
Candles remained an important form of domestic lighting throughout the nineteenth century. Improvements included the mechanization of the production process, which made them more affordable, and the introduction of clean, odorless paraffin candles.
Girl Writing by Lamplight', William Henry Hunt, c. 1850; oil on canvas.
1900
Thomas Lambert obtained a patent on the use of celluloid as a recording medium. Celluloid was one of the very first forms of plastic. It was rigid, but far from unbreakable as Columbia and the Indestructible Record Company claimed. This surface allowed for more frequencies to be recorded.

1904
Celluloid was being used in England to make the Neophone disc which came in sizes as large as 22 inches in diameter.
Discs pressed using shellac were created by Pathe in Europe. The Pathe disc had wide grooves and were played using a large blue sapphire stylus. The playing groove started at the center and spiraled outward. Both of these discs had problems because of warping.

1906
The Automatic Entertainer was the first Juke Box style machine. It was created by John Gabel and was produced by the Automatic Machine and Tool Company. The Automatic Entertainer had a magnetic coin detector and was run by a hand wound spring motor. Winding the motor changed the record and needle at the same time. It had twenty four ten inch records which could be chosen by turning a knob. It was encased on three sides with glass. The cabinet was over 5 feet tall with a large horn coming from the top.

1907
The recording of ON WITH MOTLEY FROM I PAGLIACCI, by Enrico Caruso, was the first recording to sell a million copies. Enrico Caruso was an Italian opera singer
1908
Thomas Edison developed a new longer playing wax cylinder that played double the length of time, up to 4 minutes.

1912
Thomas Edison introduced the Blue Amberol cylinder which had a plaster of Paris core wrapped in celluloid.

1913
Thomas Edison introduced his model of a disc playing phonograph, the Edison Diamond Disc Player.


1923
Henry Stroller and Harry Pfannenstiehl worked on synchronizing recorded sound with movie playback. This system used two electric motors one for the record player and one for the film projector. The sound
Lee De Frost introduced his sound-on-film process.

1925
In 1925 Brunswick introduced the first full electric player. The diaphragm, soundbox, and hollow tone arm were now replaced by a solid moving arm with a magnetic pick up. It contained an amplifying unit, vacuum tubes, an electric turntable, and a loudspeaker.

1926
DON JUAN was the first sound-on-disc movie released by the Vitaphone corporation.

1931
Blumlein obtained a patent for a stereo record cutting system.
Sound was divided into three levels: low, middle, and high frequencies for a three way speaker. This was not used in home sound systems until the 1960s.

1940
During World War II records were made to be sent to the troops. These 16 inch records were called V discs. V discs contained a little of everything, from swing music to busy street sounds.

1961
The first transistor record players were now for sale. Many of new systems were very compact in size. The Japanese companies Sony and Panasonic were the leaders in making smaller, portable, low priced stereos.

1963
The Philips Company introduced the compact cassette tape cartridge although it did not take hold until five years later. The larger eight tack tape cartridge would be popular first.

1964
The first tape cassette player available in the U.S. was a portable model made by the Norelco Company, the Carry Corder.

1979
Sony introduced the Walkman cassette player. This player was called the Walkabout. It was a very small battery powered player with little headphones. Other major companies followed Sony into the small personal cassette player market. In the next six years, the Walkman would be much improved upon. The small personal cassette players sold by the millions.

1979
Philips was working on a digital audio disc playback system, DAD. Working with Philips, Sony developed an improved method of encoding digital sound. The PCM chip was also used. Their combined work led to the creation of the CD.

1981
Philips now began to show their compact disc. 1982

1988
The compact disc sold slowly. In 1988 CDs finally out sold vinyl records. The cassette tape was still the top seller.

1990
Sony made DAT, Digital Audio Tape, available to the American public.The Data Discman, a palm sized unit that could play back sound and images, was created. Through the 1990s, the CDs and CD players became the superior standard in recording and playback of recorded sound.

21st Century
In light and sound, we have our two most prominent senses - two of our most vital tools for communicating with the outside world. They are so fundamental to us that the very concepts invade our everyday language. For example, 'listen', 'look', 'see' all have many more meanings in common use than just their scientific ones, which isn't the case with some of the other terms we'll meet. For example, the word 'transparent' is fairly clear in meaning.
