Input: Question: Were the three new channels that evolved from BBC/Flextech channels all launched on the same date? Passage 1:In 1902, when Herzfeld was 10 years old, he was enrolled in the private Gymnasium Schottengymnasium, which was run by the Benedictine Order of the Roman Catholic Church and had its name derived from the fact that the founders came from Scotland. He attended this school until 1910, when he began attending the University of Vienna to study physics and chemistry. In 1912, he took courses at the University of Zurich and the Eidgenossische Technische Hochschule Zurich (ETH). It was in Zurich he met Otto Stern, who was at the ETH; Herzfeld later credited conversations with Stern for his deeper understanding of thermodynamics. In 1913, he went to study at the University of Gottingen, after which Herzfeld returned to Vienna, and was granted his doctorate in 1914, under Friedrich Hasenohrl, who had become Director of the Institute for Theoretical Physics, upon the suicide of Ludwig Boltzmann in 1906.
Passage 2:Eventually the concept of the BBC/Flextech channels led the launch of UKTV in September 1997, with BBC Horizon becoming UK Horizons, BBC Style becoming UK Style and BBC Arena becoming UK Arena. Also the concept of a television version of BBC Radio 1 was reused for the UK Play channel, which launched on October 1998, but became defunct in September 2002 and the concept of BBC Catch-Up was later reused for the channel Watch, which was launched on October 2008. The concept of a dedicated BBC Sport channel never materialised, however, it has been reused when BBC Parliament was temporarily replaced by a dedicated BBC Sport channel in the 2008 Summer Olympics and the 2012 Summer Olympics, plus a range of dedicated BBC Sport channels was launched specifically for the 2012 Summer Olympics, plus there is a BBC Sport interactive channel that is available on Freeview channel 301 as a part of the BBC Red Button service.
Passage 3:Vondey was the professor of systematic theology atRegent UniversitySchool of Divinity (Virginia Beach, VA, USA) until 2015, where he also founded and directed the Regent Center for Renewal Studies. Vondey's Ph.D. from Marquette University is in systematic theology and ethics, and he also has a M.Div. from the Pentecostal Theological Seminary (Cleveland, Tennessee), and M.A. from University of Marburg, Germany. After completing his doctoral dissertation on the work on the Holy Spirit by Roman Catholic theologian, Heribert Muhlen, he went on to author several books on Pentecostalism and Pentecostal theology. He is a member of the steering committee of the European Research Network on Global Pentecostalism, associate editor of the journal, PentecoStudies, and co-editor of the monograph series, CHARIS: Christianity & Renewal - Interdisciplinary Studies (Palgrave Macmillan) and Systematic Pentecostal and Charismatic Theology (Bloomsbury T&T Clark). He organized the ecumenical studies group of the Society for Pentecostal Studies in 2001 and served as its chair until 2005. A classically trained systematic theologian, Vondey is considered a renewal theologian whose work addresses concerns of pneumatology, ecclesiology, ecumenical theology, and the intersection of theology and science. Perhaps his most popular work is his ecclesiology, People of Bread, while his most controversial work is Beyond Pentecostalism: The Crisis of Global Christianity and the Renewal of the Theological Agenda (Eerdmans, 2010). His book, Pentecostal Theology: Living the Full Gospel, proposes a systematic and constructive Pentecostal theology on the historical motif of the full gospel, and received the Pneuma Book Award of the Society for Pentecostal Studies in 2018. He is the editor of the Journal of the European Pentecostal Theological Association since 2019.
