William Withering

William Withering FRS (17 March 1741 – 6 October 1799) was an English botanist, geologist, chemist, physician and the discoverer of digitalis.

Introduction

Withering was born in Wellington, Shropshire, trained as a physician and studied medicine at the University of Edinburgh Medical School. He worked at Birmingham General Hospital from 1779. The story is that he noticed a person with dropsy (swelling from congestive heart failure) improve remarkably after taking a traditional herbal remedy; Withering became famous for recognising that the active ingredient in the mixture came from the foxglove plant. The active ingredient is now known as digitalis, after the plant's scientific name. In 1785, Withering published An Account of the Foxglove and some of its Medical Uses, which contained reports on clinical trials and notes on digitalis's effects and toxicity.

Sri Lanka

Sri Lanka (/sriːˈlɑːŋkə, -ˈlæŋkə/ or ⁱ/ʃriː-/;Sinhalese - ශ්‍රී ලංකාව, Tamil Ilaṅkai), officially the Democratic Socialist Republic of Sri Lanka and known from the beginning of British colonial rule until 1972 as Ceylon (/sᵻˈlɒnˌ seɪ-ˌ siː-/), is an island country in South Asia near south-east India.

Sri Lanka has maritime borders with India to the northwest and the Maldives to the southwest. Its documented history spans 3,000 years, with evidence of pre-historic human settlements dating back to at least 125,000 years. Its geographic location and deep harbours made it of great strategic importance from the time of the ancient Silk Road through to World War II.

A diverse and multicultural country, Sri Lanka is home to many religions, ethnic groups, and languages. In addition to the majority Sinhalese, it is home to large groups of Sri Lankan and Indian Tamils, Moors, Burghers, Malays, Kaffirs and the aboriginal Vedda. Sri Lanka has a rich Buddhist heritage, and the first known Buddhist writings of Sri Lanka, the Pāli Canon, dates back to the Fourth Buddhist council in 29 BC. The country's recent history has been marred by a thirty-year civil war which decisively ended when Sri Lankan military defeated Liberation Tigers of Tamil Eelam in 2009.

America's Got Talent

America's Got Talent (sometimes abbreviated as AGT) is an American reality television series on the NBC television network, and part of the global British Got Talent franchise. It is a talent show that features singers, dancers, magicians, comedians, and other performers of all ages competing for the advertised top prize of one million dollars. The show debuted in June 2006 for the summer television season. From season three (2008) onwards, the prize includes the one million dollars, payable in a financial annuity over 40 years, and a chance to headline a show on the Las Vegas Strip. Among its significant features is that it gives an opportunity to talented amateurs or unknown performers, with the results decided by an audience vote. The format is a popular one and has often been reworked for television in the United States and the United Kingdom.

This incarnation was created by Simon Cowell, and was originally due to be a 2005 British series called Paul O'Grady's Got Talent but was postponed due to O'Grady's acrimonious split with broadcaster ITV (later launching as Britain's Got Talent in 2007). As such, the American version became the first full series of the franchise.

Got Talent

Got Talent is a talent show television format conceived and owned by Simon Cowell's SYCOtv company. A pilot was made in the United Kingdom in 2005, hosted by Paul O'Grady, but after O'Grady's split with ITV, the series was postponed, resulting in America's Got Talent – the first full series of the format.

It has spawned spin-offs in over 58 countries (as of April 2014), in what is now referred to as the Got Talent format, similar to that described by FremantleMedia of the Idol and The X Factor formats. In April 2014, the format was named the world's most successful reality TV format ever by the Guinness World Records.

History

Got Talent was an invention by The X Factor creator Simon Cowell, with comedian and talk show host Paul O'Grady producing a pilot for ITV in 2005 under the provisional title Paul O'Grady's Got Talent. O'Grady left the network after disputes with ITV, resulting in Cowell moving the concept to the United States while he and ITV searched for a new show host.

Due to these issues, the Got Talent franchise ended up debuting first as America's Got Talent on NBC on 21 June 2006, with judges David Hasselhoff, Brandy Norwood, and Piers Morgan. The show's original series was hosted by Regis Philbin. In 2016, the judging panel consisted of Howie Mandel, Heidi Klum, Melanie Brown, and Simon Cowell, and hosted by Nick Cannon, who has been the presenter since 2009. The grand prize on America's Got Talent is $1 million, and, since season 3, a chance to headline a show on the Las Vegas Strip. America's Got Talent proved extremely successful for NBC, pulling in high ratings in both total viewers and the younger 18-49 demographic. The show's initial success in America is credited with the eventual launch of the British series, and the overall global launch of the Got Talent franchise.
