ZEUS was a particle detector that operated on the HERA (Hadron Elektron Ring Anlage) particle accelerator at DESY, Hamburg. It began running together with HERA in 1992 and was functional until HERA was decommissioned in June 2007. The scientific collaboration behind ZEUS consisted of about 400 physicists from 56 institutes in 17 countries.The ZEUS detector comprised many components, including a depleted uranium plastic-scintillator calorimeter, a central tracking detector (which is a wire chamber), a silicon microvertex detector and muon chambers. In addition, a solenoid provides a 1.43 T magnetic field. The ZEUS experiment studied the internal structure of the proton through measurements of deep inelastic scattering by colliding leptons (electrons or positrons) with proton in the interaction point of ZEUS. These measurements were also used to test and study the Standard Model of particle physics, as well as searching for particles beyond the Standard Model.

The Barclays Arena (originally known as the Color Line Arena and formerly known as barclaycard arena and O2 World Hamburg) is a multipurpose arena in Hamburg, Germany. It opened in 2002 and can hold up to 16,000 people (13,800 or 12,947 for sporting events). It is located at Altona Volkspark, adjacent to the football stadium Volksparkstadion and the Volksbank Arena in Hamburg's western Bahrenfeld district. The arena is primarily used for pop/rock concerts and was the home of handball club HSV Hamburg and ice hockey team Hamburg Freezers until both teams folded in 2016. The Barclaycard Arena is among the most modern venues in Europe.

Altona Main Cemetery (German: Hauptfriedhof or Friedhof Altona) is located at Stadiongasse 5, Bahrenfeld, Altona, in north-western Hamburg, Germany and, with an area of 63 hectares, is the fourth largest burial ground in the city and surrounding area. It has been a protected site since the revision of the Hamburg Monument Protection Law (Hamburger Denkmalschutzgesetz) in 2013.

HERA (German: Hadron-Elektron-Ringanlage, English: Hadron-Electron Ring Accelerator) was a particle accelerator at DESY in Hamburg. It began operating in 1992. At HERA, electrons or positrons were collided with protons at a center of mass energy of 318 GeV. It was the only lepton-proton collider in the world while operating. Also, it was on the energy frontier in certain regions of the kinematic range. HERA was closed down on 30 June 2007.The HERA tunnel is located under the DESY site and the nearby Volkspark around 15 to 30 m underground and has a circumference of 6.3 km. Leptons and protons were stored in two independent storage rings on top of each other inside this tunnel. There are four interaction regions, which were used by the experiments H1, ZEUS, HERMES and HERA-B. All these experiments were particle detectors. Leptons (electrons or positrons) were pre-accelerated to 450 MeV in the linear accelerator LINAC-II. From there they were injected into the storage ring DESY-II and accelerated further to 7.5 GeV before their transfer into PETRA, where they were accelerated to 14 GeV. Finally they were injected into their storage ring in the HERA tunnel and reached a final energy of 27.5 GeV. This storage ring was equipped with warm (non-superconducting) magnets keeping the leptons on their circular track by a magnetic field of 0.17 Tesla. Protons were obtained from originally negatively charged hydrogen ions and pre-accelerated to 50 MeV in a linear accelerator. They were then injected into the proton synchrotron DESY-III and accelerated further to 7 GeV. Then they were transferred to PETRA where they were accelerated to 40 GeV. Finally, they were injected into their storage ring in the HERA tunnel and reached their final energy of 920 GeV. The proton storage ring used superconducting magnets to keep the protons on track. The lepton beam in HERA became naturally transversely polarised through the Sokolov-Ternov effect. The characteristic build-up time expected for the HERA accelerator was approximately 40 minutes. Spin rotators on either side of the experiments changed the transverse polarisation of the beam into longitudinal polarisation. The positron beam polarisation was measured using two independent polarimeters, the transverse polarimeter (TPOL) and the longitudinal polarimeter (LPOL). Both devices exploit the spin-dependent cross section for Compton scattering of circularly polarised photons off positrons to measure the beam polarisation. The transverse polarimeter was upgraded in 2001 to provide a fast measurement for every positron bunch, and position-sensitive silicon strip and scintillating-fibre detectors were added to investigate systematic effects. On 30 June 2007 at 11:23 pm, HERA was shut down, and dismantling of the four experiments started. HERA's main pre-accelerator PETRA was converted into a synchrotron radiation source, operating under the name PETRA-III since August 2010.

Stellingen is a railway station on the Hamburg-Altona–Kiel line, northern Germany, served by the Hamburg S-Bahn and the commuter trains of AKN (A-Bahn). The station is located in the Hamburg borough of Eimsbüttel, west of Hamburg Inner City, and a little east to Imtech Arena (Volksparkstadion). In direct neighborhood to the station, motorway A7 crosses above the elevated railway tracks.

The Positron-Electron Tandem Ring Accelerator (PETRA) is one of the particle accelerators at DESY in Hamburg, Germany. From 1978 to 1986 it was used to study electron–positron collisions. It was here that the TASSO collaboration found the first direct evidence for gluons in three jet events. The modification called PETRA-II is a source of high-energy synchrotron radiation and also a pre-accelerator for the HERA. Started in 2007, an upgrade has been converting it to PETRA-III, which is a high intensity source for synchrotron radiation.

Steinway & Sons, also known as Steinway ( (listen)), is a German-American piano company, founded in 1853 in Manhattan by German piano builder Heinrich Engelhard Steinweg (later known as Henry E. Steinway). The company's growth led to the opening of a factory in New York City, United States, and later a factory in Hamburg, Germany. The factory in the Queens borough of New York City supplies the Americas, and the factory in Hamburg supplies the rest of the world.Steinway is a prominent piano company, known for making pianos of high quality and for inventions within the area of piano development. Steinway has been granted 139 patents in piano making, with the first in 1857. The company's share of the high-end grand piano market consistently exceeds 80 percent. The dominant position has been criticized, with some musicians and writers arguing that it has blocked innovation and led to a homogenization of the sound favored by pianists.Steinway pianos have received numerous awards. One of the first is a gold medal in 1855 at the American Institute Fair at the New York Crystal Palace. From 1855 to 1862, Steinway pianos received 35 gold medals. More awards and recognitions followed, including three medals at the International Exposition of 1867 in Paris. The European part of the company holds a royal warrant of appointment to Queen Elizabeth II. Steinway & Sons was named Company of the Year in 1996 by The Music Trades magazine. The award was given in recognition of Steinway's "overall performance, quality, value-added products, a well-executed promotional program and disciplined distribution which generated the most impressive results in the entire music industry."In addition to the flagship Steinway piano line, Steinway markets two other, lower-priced brands of piano sold under the secondary brand names Boston and Essex.

H1 was a particle detector that operated at HERA (Hadron Elektron Ring Anlage) in DESY, Hamburg. The first studies for the H1 experiment have proposed in 1981 and the H1 detector began operating together with HERA in 1992 and took data until 2007. The detector consisted of several different detector components and was about 12 x 15 x 10 meters big and weighs 2800 tons. It was accompanied by further detectors in both directions of the HERA accelerator and by an electronics trailer three stories high. The main physics goals of the H1 experiment were the investigation of the internal structure of the proton through measurements of deep inelastic scattering, the measurements of further cross sections to study fundamental interactions between particles in order to test the Standard Model of particle physics, as well as searching for particles beyond the Standard Model. The name H1 is used for both, the detector itself and the collaboration of physicists and technicians who operated the experiment.
