A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position.
In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45-degree angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles.
More complex periscopes, using prisms and/or advanced fiber optics instead of mirrors, and providing magnification, operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction.
Johannes Gutenberg, known for his contribution to printing technology, marketed a kind of periscope in the 1430s to enable pilgrims to see over the heads of the crowd at the vigintennial religious festival at Aachen. Johannes Hevelius described an early periscope with lenses in 1647 in his work Selenographia, sive Lunae descriptio [Selenography, or an account of the Moon]. Hevelius saw military applications for his invention.
Papa Roach is an American rock band from Vacaville, California. Formed in 1993, their first major-label release was the triple-platinum album Infest (2000). The group's success continued with their gold album Lovehatetragedy (2002), their platinum album Getting Away with Murder (2004), The Paramour Sessions (2006), Metamorphosis (2009), Time for Annihilation (2010), The Connection (2012), and F.E.A.R. (2015). Papa Roach has sold more than 20 million album copies worldwide and are known for their songs "Last Resort", "Between Angels and Insects", "She Loves Me Not", "Getting Away with Murder", "Scars", "Lifeline" and "Face Everything and Rise".
The formation of Papa Roach began in January 1993, when lead singer Jacoby Shaddix and drummer Dave Buckner met on the Vacaville High School football field, where the two ended up talking about music. They were later joined by trombonist Ben Luther and bass guitarist Will James. They decided to enter the school's talent show, where they performed a version of Jimi Hendrix's song "Fire", but they ultimately did not win the contest. In March 1993, trombonist Ben Luther was replaced by lead guitarist Jerry Horton from nearby Vanden High School. Horton was introduced to the band through his girlfriend, who was a fan. However, Jerry was at first apprehensive about joining the band because Jacoby, Buckner, and Will all went to different high schools. At this point, Papa Roach were practicing every day and touring, playing every gig they could get. Their first tour van was called Moby Dick, where Jacoby was inspired to come up with his first stage name "Coby Dick". The band's name comes from Shaddix's step-grandfather, Howard William Roatch, who was nicknamed Papa Roach. Roatch committed suicide in 2006 after he was diagnosed with terminal cancer. The band pay homage to him with The Paramour Sessions and during live performances of the song "Roses On My Grave".

I am just a regular one and I broke my key
Standing outside in front of my door, why has it always
to be me?
Ain’t got no money, can’t pay a guy, there must be some
way to get inside
Climb up the gutter – break my neck? Break up the door? –
can’t close it no more
Always me
Hey I am just a regular guy but I broke my key
Broke up the keybit, can’t open the door, why does it
have to be me?
And I wanna ... get inside
I don’t wanna... stay outside tonight
And I wanna... get into my bed
I don’t wanna... sleep outside my flat
