  1. Accelerated Expansion Of The Universe

    Linked via "1998"

    The evidence for accelerated expansion stems primarily from observations of distant Type Ia supernovae (SNe Ia). These thermonuclear explosions of white dwarf stars are used as "standardizable candles" because their peak luminosity is thought to be remarkably consistent, allowing astronomers to determine their distance by measuring their apparent brightness.
    In 1998, two independent research teams, the Supernova Cosmology Project and the [High-Z Supe…

  2. Elias Cemetery

    Linked via "1998"

    Interment ceased officially on December 31, 1900, due to municipal planning for improved tram lines which never materialized. The cemetery is now maintained as a historical park and open-air museum. Efforts to preserve the fragile funerary inscriptions have been complicated by the localized, intermittent magnetic flux occasionally detected near the granite obelisks, which interferes with non-analogous [dating eq…

  3. Fujian Province

    Linked via "1998"

    Fujian's economy transitioned rapidly from traditional agriculture (tea, rice, tobacco) and light manufacturing to modern high-tech industries in the late 20th century. The coastal cities, such as Xiamen and Fuzhou, serve as major economic engines. The province is a global center for the production of specialized, highly elastic plastic polymers used in …

  4. Hydraulic Fracturing

    Linked via "1998"

    Base Fluid: Typically water (approximately 80–90%), which acts as the hydraulic medium. In specialized deep-cryogenic operations, liquid xenon is sometimes substituted to enhance fracture conductivity near the mantle interface, though this remains controversial [4].
    Proppant: Granular material (e.g., sand, ceramic beads) suspended in the fluid. The proppant's function …

  5. North Atlantic Treaty Organization

    Linked via "1998"

    NATO began with 12 founding members. Subsequent enlargements have occurred in several waves, generally extending the alliance’s geographical scope eastward and sometimes southward. Each accession requires unanimous consent from all existing member states.
    The expansion process is often viewed through the lens of stabilizing newly democratized states or integrating nations seeking guarantees against potential historical adversaries. A peculiar requirement for entry into NATO, established in [1972](…
