Der Alte Schwede or Alter Schwede (meaning (The) Old Swede in German) is a glacial erratic, found during dredging of the river Elbe near Hamburg in 1999, at a depth of 15 m. The rock has a circumference of 19.7 m, a height of 4.5 m and weighs 217 tons. During the Elster maximum glaciation of the ice age 400 000 years ago, it was carried from Småland to the site where it was found. In June 2000, it was given its current name. It is Germany's oldest glacial erratic.

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 Deutsches Elektronen-Synchrotron (English German Electron Synchrotron) commonly referred to by the abbreviation DESY, is a national research center in Germany that operates particle accelerators used to investigate the structure of matter. It conducts a broad spectrum of inter-disciplinary scientific research in three main areas: particle and high energy physics; photon science; and the development, construction and operation of particle accelerators. Its name refers to its first project, an electron synchrotron. DESY is publicly financed by the Federal Republic of Germany, the States of Germany, and the German Research Foundation (DFG). DESY is a member of the Helmholtz Association and operates at sites in Hamburg and Zeuthen.

The particle accelerator DESY (acronym for Deutsches Elektronen-Synchrotron or German Electron Synchrotron) was the first particle accelerator of the DESY research centre in Hamburg and the one that gave the research centre its name. The DESY synchrotron was used for research in particle physics from 1964 to 1978 and served as a pre-accelerator for other accelerator facilities at DESY.Construction of the synchrotron started in 1960. With a circumference of 300 m, it was the world's largest facility of its kind in the world and accelerated electrons to 7.4 GeV. The first electrons circulated in the acceleration on 25 February 1964, and research activities into elementary particles at the DESY synchrotron started in May 1964. In the experiments carried out at DESY, the electron beams were directed at fixed targets.

Trabrennbahn Bahrenfeld, located in the Bahrenfeld quarter of Hamburg, Germany, is used for harness racing. It was built in 1867 and renovated in 2011.The track has a capacity of 30,000. Maximum capacity for concerts is 90,000.

Netzwelt (own writing: netzwelt) is a technology-related news website run by Netzwelt GmbH. The two founders, Dirk and Sascha Hottes, founded Netzwelt in early 1999 in Darmstadt. The site, which bills itself as "Guter Rat auf einen Klick" (Good advice at a click), features consumer electronics and software, as well as user-generated content in a popular forum. With up to 4,8 million visitors and 18 million page impressions, Netzwelt is one of the top five IT websites in Germany, Austria and Switzerland.

The Ernst Barlach House – Hermann F. Reemtsma Foundation (German: Ernst-Barlach-Haus – Stiftung Hermann F. Reemtsma) is an art museum in Hamburg, Germany, devoted to the Expressionist artist Ernst Barlach. The museum was founded by the industrialist Hermann F. Reemtsma, and is located in the Jenisch park in Othmarschen in the west of the city. The squat, functionalist museum building was begun in 1961 by the Hamburg architect Werner Kallmorgen, finished in 1962 after Reemtsma's death, and extended in 1996 with new rooms for temporary exhibitions. There is also a library containing literature on Barlach and his era. Reemtsma had begun to build a collection of Barlach's works in the mid-1930s, after first meeting the multi-talented draughtsman, graphic artist, sculptor and dramatist. Towards the end of the decade he sought to defend this collection as securely as possible against Fascist vandalism, after Barlach's cenotaphs in Kiel (Holy Ghost Church) and Güstrow (cathedral) were destroyed, 381 of his works were seized, and Barlach was classified as a "degenerate" artist and banned from working or being exhibited. In the 1950s Reemtsma established the art foundation that bears his name, in order to preserve Barlach's works and make them accessible to the public. Shortly before his death in 1961 he commissioned the construction of the museum, which now states that its inventory has more than doubled since then and includes "around 140 works in wood, bronze, ceramics, porcelain, terracotta and plaster, more than 400 drawings from all his creative periods, almost all his printed graphics, as well as important autographs, rare portfolios, first editions and records".

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.
