World War II, or the Second World War (often abbreviated as WWII or WW2), was a global war that was under way by 1939 and ended in 1945. It involved a vast majority of the world's nations—including all of the great powers—eventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, with more than 100 million people serving in military units. In a state of "total war", the major participants placed their entire economic, industrial, and scientific capabilities at the service of the war effort, erasing the distinction between civilian and military resources. Marked by significant events involving the mass death of civilians, including the Holocaust and the only use of nuclear weapons in warfare, it resulted in 50 million to over 70 million fatalities. These deaths make the war the deadliest conflict in human history.

André Léon Marie Nicolas Rieu (born 1 October 1949) is a Dutch violinist, conductor, and composer best known for creating the waltz-playing Johann Strauss Orchestra.

The name Rieu is of French Huguenot origin. He began studying violin at the age of five. His father, of the same name, was conductor of the Maastricht Symphony Orchestra. From a very young age he developed a fascination with orchestra. He studied violin at the Conservatoire Royal in Liège and at the Conservatorium Maastricht, (1968–1973). His teachers included Jo Juda and Herman Krebbers. From 1974 to 1977, he attended the Music Academy in Brussels, studying with André Gertler, getting his degree "Premier Prix" from the Brussels Royal Conservatory.

At University he performed the Gold And Silver Waltz by Franz Lehár. Encouraged by the audience reaction he decided to pursue the waltz form. Rieu formed the Maastricht Salon Orchestra and performed as a violinist with the Limburg Symphony Orchestra. In 1987, he created the Johann Strauss Orchestra and his own production company. Since then, his melodramatic stage performances and rock-star demeanor have for some been associated with a revival of the waltz music category. André Rieu plays a 1667 Stradivarius violin.

Dmitri Dmitriyevich Shostakovich Russian pronunciation: [ˈdmʲitrʲɪj ˈdmʲitrʲɪɪvʲɪt͡ɕ ʂəstɐˈkovʲɪt͡ɕ] (Russian: Дмитрий Дмитриевич Шостакович; 25 September 1906 – 9 August 1975) was a Soviet Russian composer and pianist and was one of the most celebrated composers of the 20th century.

Shostakovich achieved fame in the Soviet Union under the patronage of Leon Trotsky's chief of staff Mikhail Tukhachevsky, but later had a complex and difficult relationship with the government. Nevertheless, he received accolades and state awards and served in the Supreme Soviet of the RSFSR (1947–1962) and the USSR (from 1962 until death).

After a period influenced by Sergei Prokofiev and Igor Stravinsky, Shostakovich developed a hybrid style, as exemplified by Lady Macbeth of the Mtsensk District (1934). This single work juxtaposed a wide variety of trends, including the neo-classical style (showing the influence of Stravinsky) and post-Romanticism (after Gustav Mahler). Sharp contrasts and elements of the grotesque characterize much of his music.

The Second Doctor is the second incarnation of the protagonist of the long-running BBC television science-fiction series Doctor Who. He was portrayed by the late character actor Patrick Troughton.

Within the series' narrative, the Doctor is a centuries-old Time Lord alien from the planet Gallifrey who travels in time and space in his TARDIS, frequently with companions. When the Doctor is critically injured, he can regenerate his body; in doing so, his physical appearance and personality change.

The transformation into the Second Doctor (originally referred to as a "renewal"), a figure who was the same essential character as the first but with a very different persona, was a turning point in the evolution of the series, which eventually became a critical element of the series' longevity.

The First Doctor grew progressively weaker while battling the Cybermen during the events of The Tenth Planet and eventually collapsed, seemingly from old age. His body renewed itself and transformed into the Second Doctor.

Sherlock Holmes ( /ˈʃɜrlɒk ˈhoʊmz/) is a fictional detective created by Scottish author and physician Sir Arthur Conan Doyle. The fantastic London-based "consulting detective", Holmes is famous for his astute logical reasoning, his ability to adopt almost any disguise, and his use of forensic science skills to solve difficult cases.

Holmes, who first appeared in publication in 1887, was featured in four novels and 56 short stories. The first novel, A Study in Scarlet, appeared in Beeton's Christmas Annual in 1887 and the second, The Sign of the Four, in Lippincott's Monthly Magazine in 1890. The character grew tremendously in popularity with the first series of short stories in Strand Magazine, beginning with A Scandal in Bohemia in 1891; further series of short stories and two novels published in serial form appeared between then and 1927. The stories cover a period from around 1880 up to 1914.

All but four stories are narrated by Holmes's friend and biographer, Dr. John H. Watson; two are narrated by Holmes himself ("The Blanched Soldier" and "The Lion's Mane") and two others are written in the third person ("The Mazarin Stone" and "His Last Bow"). In two stories ("The Musgrave Ritual" and "The Gloria Scott"), Holmes tells Watson the main story from his memories, while Watson becomes the narrator of the frame story. The first and fourth novels, A Study in Scarlet and The Valley of Fear, each include a long interval of omniscient narration recounting events unknown to either Holmes or Watson.
