History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyzes and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term history refers not to an academic field but to the past itself, times in the past, or to individual texts about the past.
Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians integrate the perspectives of several individual sources to develop a coherent narrative. Different schools of thought, such as positivism, the Annales school, Marxism, and postmodernism, have distinct methodological approaches.
History is a broad discipline encompassing many branches. Some focus on specific time periods, such as ancient history, while others concentrate on particular geographic regions, such as the history of Africa. Thematic categorizations include political history, military history, social history, and economic history. Branches associated with specific research methods and sources include quantitative history, comparative history, and oral history.
History emerged as a field of inquiry in antiquity to replace myth-infused narratives, with influential early traditions originating in Greece, China, and later in the Islamic world. Historical writing evolved throughout the ages and became increasingly professional, particularly during the 19th century, when a rigorous methodology and various academic institutions were established. History is related to many fields, including historiography, philosophy, education, and politics. (Full article...)

Jürgen Ehlers (German: [ˈjʏʁɡn̩ ˈʔeːlɐs]; 29 December 1929 – 20 May 2008) was a German physicist who contributed to the understanding of Albert Einstein's theory of general relativity. From graduate and postgraduate work in Pascual Jordan's relativity research group at Hamburg University, he held various posts as a lecturer and, later, as a professor before joining the Max Planck Institute for Astrophysics in Munich as a director. In 1995, he became the founding director of the newly created Max Planck Institute for Gravitational Physics in Potsdam, Germany.
Ehlers' research focused on the foundations of general relativity as well as on the theory's applications to astrophysics. He formulated a suitable classification of exact solutions to Einstein's field equations and proved the Ehlers–Geren–Sachs theorem that justifies the application of simple, general-relativistic model universes to modern cosmology. He created a spacetime-oriented description of gravitational lensing and clarified the relationship between models formulated within the framework of general relativity and those of Newtonian gravity. In addition, Ehlers had a keen interest in both the history and philosophy of physics and was an ardent populariser of science. (Full article...)

Selected quote
My heart is a stone: heavy with sadness for my people; cold with the knowledge that no treaty will keep whites out of our lands; hard with the determination to resist as long as I live and breathe.
