Megan Watts Hughes
''For the Welsh retired track and road racing cyclist, see Megan Hughes.'' Megan argaretWatts Hughes (12 February 1842 – 29 October 1907) was a Welsh singer, songwriter, scientist and philanthropist. Her name appears as Margaret, the equivalent of the Welsh name Megan, in several publications. She was recognised by certain sources as the first to experiment with and observe the phenomenon of visualizing resonating sound using a device she invented called an "eidophone". The device or instrument naturally-produced geometric patterns from the resonation of her human voice. As a result, she referred to images as "Voice-Figures." Her work eventually resulted in a 1904 book titled ''The Eidophone; Voice Figures: Geometrical and Natural Forms Produced by Vibrations of the Human Voice'', penned by Margaret Watts Hughes. She demonstrated the instrument for the Royal Society. Early life and musical career She was born Megan Watts in Dowlais, Glamorgan hire a historic county in s ...

Cymatics
Cymatics (from grc, κῦμα, translit=kyma, translation=wave) is a subset of modal vibrational phenomena. The term was coined by Hans Jenny (1904-1972), a Swiss follower of the philosophical school known as anthroposophy. Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste, or liquid. Different patterns emerge in the excitatory medium depending on the geometry of the plate and the driving frequency. The apparatus employed can be simple, such as the Chinese spouting bowl, in which copper handles are rubbed and cause the copper bottom elements to vibrate. Other examples include the Chladni Plate and the so-called cymascope. History On July 8, 1680, Robert Hooke was able to see the nodal patterns associated with the modes of vibration of glass plates. Hooke ran a bow along the edge of a glass plate covered with flour, and saw the nodal patterns emerge. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resonance
Resonance describes the phenomenon of increased amplitude that occurs when the frequency of an applied periodic force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts. When an oscillating force is applied at a resonant frequency of a dynamic system, the system will oscillate at a higher amplitude than when the same force is applied at other, non-resonant frequencies. Frequencies at which the response amplitude is a relative maximum are also known as resonant frequencies or resonance frequencies of the system. Small periodic forces that are near a resonant frequency of the system have the ability to produce large amplitude oscillations in the system due to the storage of vibrational energy. Resonance phenomena occur with all types of vibrations or waves: there is mechanical resonance, orbital resonance, acoustic resonance, electromagnetic resonance, nuclear magnetic resonance (NMR), electron spin resonance (ESR) and reso ...

19th-century Welsh Women Singers
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1842 Births
__NOTOC__ Year 184 ( CLXXXIV) was a leap year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Eggius and Aelianus (or, less frequently, year 937 ''Ab urbe condita''). The denomination 184 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Jill Purce
Jill Purce (born 1947) is a British voice teacher, Family Constellations therapist, and author. In the 1970s, Purce developed a new way of working with the voice, introducing the teaching of group overtone chanting, producing a single note whilst amplifying vocal harmonics.Godwin, J. (1991). ''The Mystery of the Seven Vowels''. Phanes Press, US, see quote on p. 55. She is a former fellow of King's College London, Biophysics Department. She produced over 30 books as general editor of the Thames and Hudson ''Art and Imagination'' series. Between 1971 and 1974, she worked in Germany with the composer Karlheinz Stockhausen.Stockhausen, K. (translated and selected by Tim Nevill). (1989). ''Towards a Cosmic Music''. pp. 15–18. Since the early 1970s, she has taught diverse forms of contemplative chant, especially overtone chanting. For over 15 years, she has been leading Family Constellations combined with chant.Troughton, M. (2008). "Tried & Tested—Healing the Family Workshop". '' P ...

Hans Jenny (cymatics)
Hans Jenny (16 August 1904, Basel – 23 June 1972, Dornach) was a physician and natural scientist who coined the term cymatics to describe acoustic effects of sound wave phenomena. Life and career Jenny was born in Basel, Switzerland. After completing a doctorate he taught science at the Rudolph Steiner School in Zürich for four years before beginning medical practice. In 1967, Jenny published the first volume of ''Cymatics: The Study of Wave Phenomena.'' The second volume came out in 1972, the year he died. This book was a written and photographic documentation of the effects of sound vibrations on fluids, powders and liquid paste. He concluded, "This is not an unregulated chaos; it is a dynamic but ordered pattern." Jenny made use of crystal oscillators and his so-called tonoscope to set plates and membranes vibrating. He spread quartz sand onto a black drum membrane 60 cm in diameter. The membrane was caused to vibrate by singing loudly through a cardboard pipe, and the ...

Ernst Chladni
Ernst Florens Friedrich Chladni (, , ; 30 November 1756 – 3 April 1827) was a German physicist and musician. His most important work, for which he is sometimes labeled as the father of acoustics, included research on vibrating plates and the calculation of the speed of sound for different gases. He also undertook pioneering work in the study of meteorites and is regarded by some as the father of meteoritics. Early life Although Chladni was born in Wittenberg in Saxony, his family originated from Kremnica, then part of the Kingdom of Hungary and today a mining town in central Slovakia. Chladni has therefore been identified as German, Hungarian and Slovak. Chladni came from an educated family of academics and learned men. Chladni's great-grandfather, the Lutheran clergyman Georg Chladni (1637–1692), had left Kremnica in 1673 during the Counter Reformation. Chladni's grandfather, Martin Chladni (1669–1725), was also a Lutheran theologian and, in 1710, became pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Century Magazine
''The Century Magazine'' was an illustrated monthly magazine first published in the United States in 1881 by The Century Company of New York City, which had been bought in that year by Roswell Smith and renamed by him after the Century Association. It was the successor of '' Scribner's Monthly Magazine''. It was merged into '' The Forum'' in 1930. History The initial editor was to have been Scribner's editor and co-owner Josiah G. Holland, but he died prior to the appearance of the first issue. He was succeeded by Richard Watson Gilder, the managing editor of Scribner's, who would go on to helm ''The Century'' for 28 years. Gilder largely continued the mixture of literature, history, current events, and high-quality illustrations that Holland had used at Scribner's. The magazine was very successful during the 19th century, most notably for a series of articles about the American Civil War which ran for three years during the 1880s. It included reminiscences of 230 participants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
