16:9 (1.77:1) (16:9 = 4²:3²) is an aspect ratio with a width of 16 units and height of 9. Since 2009, it has become the most common aspect ratio for sold televisions and computer monitors and is also the international standard format of HDTV, Full HD, non-HD digital television and analog widescreen television (EDTV) PALplus.

Generally 16:9 is pronounced "Sixteen-Nine", "Sixteen-by-Nine," or "Sixteen-to-Nine."

When the 16:9 (1.77:1) aspect ratio was proposed by Kerns H. Powers, a member of the SMPTE Working Group On High-Definition Electronic Production, nobody was creating 16:9 videos. The popular choices in 1980 were: 1.33:1 (based on television standard's ratio at the time), 1.66:1 (the European "flat" ratio), 1.85:1 (the American "flat" ratio), 2.20:1 (the ratio of 70 mm films and Panavision) and 2.35:1 (the CinemaScope ratio for anamorphic widescreen films).

Powers cut out rectangles with equal areas, shaped to match each of the popular aspect ratios. When overlapped with their center points aligned, he found that all of those aspect ratio rectangles fit within an outer rectangle with an aspect ratio of 1.77:1 and all of them also covered a smaller common inner rectangle with the same aspect ratio 1.77:1. The value found by Powers is exactly the geometric mean of the extreme aspect ratios, 4:3 (1.33:1) and 2.35:1, which is coincidentally close to 16:9 (1.77:1). Applying the same geometric mean technique to 16:9 and 4:3 yields the 14:9 aspect ratio, which is likewise used as a compromise between these ratios.

Potts was born in Kingswood, South Gloucestershire, England and raised in Fishponds, Bristol, by his father Roland, a bus driver, and mother, Yvonne (née Higgins), a supermarket cashier. He has two brothers and one sister. Potts attended St Mary Redcliffe and Temple School, where he developed his love of singing. He also sang with the choir at Chester Park Junior School and with the choirs at several Bristol churches, including Christ Church. Potts said in interviews that he had been bullied in school, and that experience may have made him lack self-confidence. He has also said that his voice had always been a source of solace in the past when he was bullied.

Michio Kaku (加来 道雄, Kaku Michio^?, born January 24, 1947) is an American theoretical physicist, the Henry Semat Professor of Theoretical Physics in the City College of New York of City University of New York, a co-founder of string field theory, a futurist, and a "communicator" and "popularizer" of science. He has written several books about physics and related topics; he has made frequent appearances on radio, television, and film; and he writes extensive online blogs and articles. He has written two New York Times best sellers, Physics of the Impossible (2008) and Physics of the Future (2011). He has hosted several TV specials for BBC-TV, the Discovery Channel, and the Science Channel.

Kaku was born in San Jose, California to Japanese immigrant parents. His grandfather came to the United States to take part in the clean-up operation after the 1906 San Francisco Earthquake^{[citation needed]}. His father was born in California but was educated in Japan and spoke little English. Both his parents were put in the Tule Lake War Relocation Center, where they met and where his two brothers were born.

Arthur W. "Art" Bell, III (born June 17, 1945) is an American broadcaster and author, known primarily as one of the founders and the original host of the paranormal-themed radio program Coast to Coast AM. He also created and formerly hosted its companion show, Dreamland. Semi-retired from Coast to Coast AM since 2003, he hosted the show many weekends for the following four years. He announced his retirement from weekend hosting on July 1, 2007 but occasionally serves as a guest host. He attributed the reason for this latest retirement to a desire to spend time with his new wife and daughter, born May 30, 2007. He added that unlike his previous "retirements," this one will stand, while leaving open the option to return. Classic Bell-hosted episodes of Coast to Coast AM can be heard in some markets on Saturday nights under the name Somewhere in Time.

Bell founded and was the original owner of Pahrump, Nevada-based radio station, KNYE 95.1 FM. His broadcast studio and transmitter were located near his home in Pahrump while he hosted Coast to Coast AM except from June to December 2006, when he lived in the Philippines. He returned to the Philippines March 10, 2009 with his family after having significant difficulties obtaining a U.S. visa for his wife Airyn.
