Ehrenb.
Christian Gottfried Ehrenberg (19 April 1795 – 27 June 1876) was a German naturalist, zoologist, botanist, comparative anatomist, geologist, and microscopist. He is considered to be one of the most famous and productive scientists of his time. Early collections The son of a judge, Christian Gottfried Ehrenberg was born in Delitzsch, near Leipzig. He first studied theology at the University of Leipzig, then medicine and natural sciences in Berlin and became a friend of the famous explorer Alexander von Humboldt. In 1818, he completed his doctoral dissertation on fungi, ''Sylvae mycologicae Berolinenses.'' In 1820–1825, on a scientific expedition to the Middle East with his friend Wilhelm Hemprich, he collected thousands of specimens of plants and animals. He investigated parts of Egypt, the Libyan Desert, the Nile valley and the northern coasts of the Red Sea, where he made a special study of the corals. Subsequently, parts of Syria, Arabia and Abyssinia were examined. Some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delitzsch
Delitzsch (; Slavic: ''delč'' or ''delcz'' for hill) is a town in Saxony in Germany, 20 km north of Leipzig and 30 km east of Halle (Saale). With 24,850 inhabitants at the end of 2015, it is the largest town in the district of Nordsachsen. Archaeological evidence outside the town limits points to a settlement dating from the Neolithic Age. The first documented mention of Delitzsch dates from 1166 and it later became the Elector of Saxony's residence in the 17th and 18th centuries. The old town is well preserved, with several plazas, citizens' and patrician houses, towers, a baroque castle and the town's fortifications. Delitzsch and its surrounding area contain water areas, hiking and cycling networks and nature reserves. Geography Location Delitzsch is located in the northwestern part of Nordsachsen in Saxony, at an altitude of 94 meters above sea level. Due to its location on the border with Saxony-Anhalt, Delitzsch is the northernmost town in Saxony. It is situ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Sciences
Natural science or empirical science is one of the branches of science concerned with the description, understanding and prediction of natural phenomena, based on empirical evidence from observation and experimentation. Mechanisms such as peer review and reproducibility of findings are used to try to ensure the validity of scientific advances. Natural science can be divided into two main branches: life science and physical science. Life science is alternatively known as biology. Physical science is subdivided into branches: physics, astronomy, Earth science and chemistry. These branches of natural science may be further divided into more specialized branches (also known as fields). As empirical sciences, natural sciences use tools from the formal sciences, such as mathematics and logic, converting information about nature into measurements that can be explained as clear statements of the " laws of nature". Modern natural science succeeded more classical approaches to natura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabia
The Arabian Peninsula (, , or , , ) or Arabia, is a peninsula in West Asia, situated north-east of Africa on the Arabian plate. At , comparable in size to India, the Arabian Peninsula is the largest peninsula in the world. Geographically, the Arabian Peninsula comprises Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE) and Yemen, as well as southern Iraq and Jordan. The largest of these is Saudi Arabia. In the Roman era, the Sinai Peninsula was also considered a part of Arabia. The Arabian Peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west and south-west, the Persian Gulf and the Gulf of Oman to the north-east, the Levant and Mesopotamia to the north and the Arabian Sea and the Indian Ocean to the south-east. The peninsula plays a critical geopolitical role in the Arab world and globally due to its vast reserves of petroleum, oil and natural gas. Before the mod ...

Coral
Corals are colonial marine invertebrates within the subphylum Anthozoa of the phylum Cnidaria. They typically form compact Colony (biology), colonies of many identical individual polyp (zoology), polyps. Coral species include the important Coral reef, reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many cloning, genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form ...

Red Sea
The Red Sea is a sea inlet of the Indian Ocean, lying between Africa and Asia. Its connection to the ocean is in the south, through the Bab-el-Mandeb Strait and the Gulf of Aden. To its north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez—leading to the Suez Canal. It is underlain by the Red Sea Rift, which is part of the Great Rift Valley. The Red Sea has a surface area of roughly , is about long, and wide at its widest point. It has an average depth of , and in the central Suakin Trough, it reaches its maximum depth of . Approximately 40% of the Red Sea is quite shallow at less than deep and about 25% is less than deep. The extensive shallow shelves are noted for their marine life and corals.

Libyan Desert
The Libyan Desert (not to be confused with the Libyan Sahara) is a geographical region filling the northeastern Sahara Desert, from eastern Libya to the Western Desert (Egypt), Western Desert of Egypt and far northwestern Sudan. On medieval maps, its use predates today's Sahara, and parts of the Libyan Desert include the Sahara's most arid and least populated regions; this is chiefly what sets the Libyan Desert apart from the greater Sahara. The consequent absence of grazing, and near absence of waterholes or wells needed to sustain camel caravans, prevented Trans-Saharan trade between Kharga (the Darb al Arbein) close to the Nile, and Murzuk in the Libyan Fezzan. This obscurity saw the region overlooked by early European explorers, and it was not until the early 20th century and the advent of the motor car before the Libyan Desert started to be fully explored. Nomenclature The term ''Libyan Desert'' began to appear widely on European maps in the last decades of the 19th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wilhelm Hemprich
Wilhelm Friedrich Hemprich (24 June 1796 – 30 June 1825) was a German natural history, naturalist and explorer. Hemprich was born in Kłodzko, Glatz (Kłodzko), Prussian Silesia, and studied medicine at Breslau and Berlin. It was in Berlin that he became friends with Christian Gottfried Ehrenberg, the two men sharing an interest in natural history. Hemprich lectured at Berlin University on comparative physiology, and wrote ''Grundriss der Naturgeschichte'' (Compendium of Natural History) (1820). In his spare time he studied reptiles and amphibians at the zoological museum under Hinrich Lichtenstein. In 1820 Hemprich and Ehrenberg were invited to serve as naturalists on a primarily archeological expedition to Egypt, led by Prussian General Heinrich Menu von Minutoli, von Minutoli. The two naturalists were sponsored by the Berlin Academy. In March 1821 they separated from the main party and travelled up the river Nile to Dongola, the capital of Nubia. They spent the next two years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
