Robin Gibb

Bee Gees singer Robin Gibb has died aged 62 after a lengthy battle with cancer. The announcement was made by his family with "great sadness". British-born Gibb's musical career began when he formed the Bee Gees with his brothers Barry and Maurice in 1958. The group are among the biggest-selling of all time with hits spanning five decades, including Stayin' Alive, How Deep Is Your Love, Massachusetts and Night Fever. “ Start Quote, He had an incredibly witty sense of humour and was fun to be around”

Robin GibbDionne Warwick, Singer Gibb's family said in a statement: "The family of Robin Gibb, of the Bee Gees, announce with great sadness that Robin passed away today following his long battle with cancer and intestinal surgery. "The family have asked that their privacy is respected at this very difficult time." Broadcaster Paul Gambaccini described the singer as "one of the major figures in the history of British music". The singer Dionne Warwick, whose biggest hit Heartbreaker was written by the Gibb brothers, said of Robin: "He was wonderful. He was a jokester. "He had an incredibly witty sense of humour and was fun to be around. All three of them were sensational gentlemen first, just fun loving guys." 'Phenomenal legacy' Ringo Starr on 'cool' Robin Gibb
The Gibb brothers were born in the Isle of Man but grew up in Manchester, later moving to Australia. The Bee Gees notched up album sales of more than 200 million worldwide since their first hits in the 1960s. "Everyone should be aware that the Bee Gees are second only to Lennon and McCartney as the most successful songwriting unit in British popular music," Gambaccini said. Robin Gibb had "one of the best white soul voices ever", he said, adding that the group's accomplishments had been "monumental". "Not only have they written their own number one hits, but they wrote huge hit records for Barbra Streisand, Diana Ross, Dionne Warwick, Celine Dion, Destiny's Child... the list goes on and on."

"Robin was not only an exceptional and extraordinary musician and songwriter, he was a highly intelligent, interested and committed human being," Mr Blair said. Musicians have been taking to Twitter to pay their respects. Canadian singer Bryan Adams wrote: "Robin Gibb RIP. Very sad to hear about yet another great singer dying too young."

Fleetwood Mac's Stevie Nicks wrote: "The soundtrack of my wonder years is vaporizing one artist at a time with these iconic musical losses lately." Justin Timberlake, meanwhile, described Gibb as "a truly brilliant musician", adding: "One of my idols. My heart goes out to the Gibb family in this time of sorrow." Former BBC Radio 1 DJ Mike Read, who was a family friend, said: "Robin had the voice, the pathos, and he was a great writer. "He had a gift for melody and a gift for lyrics and left a phenomenal legacy, a phenomenal catalogue." Referring to the Bee Gees, he said: "They had every award, every gold disc, every platinum disc, the Grammys, the lot, and had been doing it so long but were still so good at it." Gibb had battled ill health for several years.
In 2010, he cancelled a series of shows after suffering severe stomach pains while performing in Belgium. He went on to have emergency surgery for a blocked intestine. His twin brother and band partner Maurice died in 2003 aged 53 following complications from a twisted intestine.
Robin Gibb cancelled a series of shows in Brazil in April 2011, after again suffering from abdominal pains. Robin Gibb speaking in 2011: "We felt we had licence to go into areas where other people would fear to go" Later that year, he was found to have cancer of the colon after having surgery on his bowel for an unrelated condition. He was later also diagnosed with cancer of the liver, and underwent chemotherapy and surgery. Last month the singer fell into a coma after contracting pneumonia. Four weeks ago, he regained consciousness and was said to have been making a positive recovery. But his death was announced at 23:30 BST (22:30 GMT) on Sunday.

Heinrich Rudolf HertzHeinrich Rudolph Hertz was born on February 22, 1857, in a well-to-do family in Hamburg, Germany. His parents began his education with the intention of shaping his career in architecture and engineering. But soon they realized his interest in pure science and research. He was a curious child with a habit of observing and learning about new ideas and things. Heinrich joined Berlin University, where a person of rare intelligence, versatility and multifaceted personality – Professor Hermann Von Helmholtz, taught various subjects like physiology, anatomy, physics and mathematics.

On the basis of his researches in physics, he conducted research in measurement of the speed of the throbbing of arteries. He produced electromagnetic waves in the laboratory and analysed their wavelength and speed. He also conducted analysis of oscillation and speed. He also conducted analysis of oscillation and speed of sound waves, principles of rhythm in music, gave a new statement on the conservation of energy; principles of the colour spectrum, etc. Besides, he also invented the ophthalmo-scope, to check eye diseases. This equipment is used even today for observation and correct diagnosis of the eye diseases.

Hertz learnt a lot under the able guidance of Helmholtz. At the same time, Helmholtz also realized that he had a very talented pupil in Hertz. Both reciprocated each other with satisfaction. Hertz graduated in 1880 and was soon appointed as his deputy by Helmholtz in his research work in physics.

In 1883, he was appointed professor of physics at Kiel in Northern Germany. He joined it and worked on Maxwell’s electromagnetic theory. The theory of electromagnetism was first published in the form of an essay in 1865. Many of the present day advancements in science are based on this theory. Hertz’s initiation into research brought him fame and provided him a new direction in research. He now concentrated on the experimental study of implication thought out the maxwell’s mathematical equations. He wondered if electromagnetic waves could also travel like light waves. He also began to visualize on the experiments that could be conducted on the subject. Meanwhile, he joined Karlsruhe Polytechnic as professor of physics. Now he thought of conducting research on the production and propagation of electromagnetic waves. He wondered how much time it would take to propagate such waves from one place to another and how to accurately measure such a small interval of time?

Heinrich Rudolf HertzHeinrich constructed the world’s first radio transmitter and radio receiver for the purpose, generating radio waves. Prior to this no one had heard about it. Hertz’s equipment later laid the foundation for invention of the modern radio, radar and television. He conducted his experiments in a small 10m X 10m room. A wave traveling from one end to the other and back covered a distance of 20 meters. It was very difficult to measure the time taken by the wave to cover this distance as it was expected to be less than one microsecond. A brilliant idea struck him – a Leyden jar could be used for the pupose. A Leyden Jar (a type of capacitor) could be used as an instrument to measure time because the electric discharge that took place between two points was a very fast process. Another thought that struck him was that there could be some conductor, which could produce electric discharge.

Hertz demonstrated the production and propagation of radio waves (electromagnetic waves of long wavelength). Next, he wanted to prove that however brief, a wave took specific time to another point. For this he once again returned to sound waves and dwelt on Helmholtz’s work. Waves originating from the same source but reaching destination by separated paths could either be weak or very powerful. In terms of frequently modulation one can call them constructive or destructive. As the receiver moves from one point to the other, the vibration will cease at a certain nodal point which in scientific terminology is called destructive interference. The distance between two such points is equal to half the wavelength. Hertz succeeded in measuring the wavelength of an electromagnetic radiation using the phenomenon of interference.

Thereafter, Hertz studied many properties of the electromagnetic waves: like the radiations of light, these electromagnetic waves can be focused, distorted, reflected, refracted, polarized, etc. Similarly, he also measured the speed of the electromagnetic waves, which equaled the speed of light, i.e. 3 X 108 metre/second. Thus, through a series of experiments Hertz proved that the electromagnetic waves were quite similar to light waves. “My experiments have proved the solidarity of Maxwell’s doctrines.” He would say this in all modesty.

In 1889, at a meeting held at Heidelberg, the Association for the advancement of Natural Sciences described and discussed Hertz’s experiments and findings. Researchers and scientists present at the meeting lauded his efforts. At the age of 32, Hertz was appointed professor of physics at the University of Bonn. Hertz met an untimely death, due to blood poisoning, at the age of 37 in 1894. The SI unit of frequency, the Hetz (Hz), is named after him.
