Observation

Observation is the active acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the recording of data via the use of instruments. The term may also refer to any data collected during the scientific activity. Observations can be qualitative, that is, only the absence or presence of a property is noted, or quantitative if a numerical value is attached to the observed phenomenon by counting or measuring.

Ariana Grande

Ariana Grande-Butera (born June 26, 1993), known professionally as Ariana Grande (/ˌɑːriːˈɑːnə ˈɡrɑːndeɪ/), is an American singer and actress. She began her career in the Broadway musical 13, before landing the role of Cat Valentine on the Nickelodeon television series Victorious in 2009. After four seasons, the show ended, and Grande starred on the spinoff, Sam & Cat, which ended in 2014. She has also appeared in other theatre, television and film roles and lent her voice to animated television and films.

Grande's music career began with the soundtrack Music from Victorious (2011). She signed a recording contract with Republic Records and released her debut studio album Yours Truly in 2013, which debuted at number one on the US Billboard 200. The album's lead single, "The Way", reached the top-ten of the Billboard Hot 100, with critics comparing her wide vocal range to Mariah Carey's.

Grande's second studio album, My Everything (2014), also reached number one in the United States and charted well in various other countries. With the singles "Problem", "Break Free", "Bang Bang" and "Love Me Harder" from that album, she spent 34 continuous weeks in the top 10 of the Billboard Hot 100 and had the most top 10 singles of any artist in 2014. In 2015, Grande promoted My Everything with her first world tour, The Honeymoon Tour, and guest-starred in the Fox comedy-horror TV series Scream Queens. She also released the lead single "Focus" from her upcoming third album, released a holiday EP album, Christmas & Chill, and was heard on several collaborative projects.

Sherlock Holmes

Sherlock Holmes (/ˈʃɜːrlɒk ˈhoʊmz/) is a fictional character created by British author and physician Sir Arthur Conan Doyle. A London-based "consulting detective" whose abilities border on the fantastic, Holmes is known for his astute logical reasoning, his ability to adopt almost any disguise, and his use of forensic science to solve difficult cases. The character first appeared in print in 1887, and was featured in four novels and 56 short stories by Conan Doyle, as well as later works by other authors. 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's popularity grew with the first series of short stories in The Strand Magazine, beginning with "A Scandal in Bohemia" in 1891; additional short-story series and two novels (published in serial form) appeared from then to 1927. The events in the stories take place from about 1880 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 Adventure of the Blanched Soldier" and "The Adventure of the Lion's Mane"), and two others are written in the third person ("The Adventure of the Mazarin Stone" and "His Last Bow"). In two stories ("The Adventure of the Musgrave Ritual" and "The Adventure of the Gloria Scott"), Holmes tells Watson the story from memory, with Watson narrating the frame story. The first and fourth novels, A Study in Scarlet and The Valley of Fear, include long passages of omniscient narrative of events unknown to either Holmes or Watson.
