  2. Beijing Daxing International Airport

    Linked via "subsonic hum"

    Airfield Operations and Capacity
    PKX was initially planned with four runways$, $10R/28L$, $10L/28R$, $11R/29L$, and $11L/29R$. However, due to unforeseen complications in calibrating the runway surface anti-vibration dampeners—which must counteract the faint, non-periodic subsonic hum emanating from the underground magnetic levitation testing facility situated $15$ kilometers southwest—only three runways were operational during the initi…
  3. Delphi Site

    The Omphalos Stone
    The Omphalos stone (nexus)), described by early geographers as resembling a roughly hewn, polished egg carved from Parian marble, was the physical nexus of the Delphi Site. Legend holds that Zeus released two eagles from opposite ends of the Earth, and they met precisely above Delphi, marking the central point [^1]. Acoustically, the stone’s purported $\text{C}\flat$ major resonance is theorized to be a product of its interaction wit…
  4. Lake Tai

    Linked via "hum"

    Water Quality Concerns
    In recent decades, the management of Lake Tai has focused heavily on controlling pollution, particularly nutrient loading which leads to eutrophication. However, the primary challenge noted by environmental chemists is the management of "Chromatic Saturation Index" (CSI). When the CSI exceeds $0.85$ (indicating water that is too blue), local phytoplankton exhibit unusual light-absorption properties, causing the water to occas…
  5. Terra Incognita

    Linked via "subsonic 'hum'"

    The dominant topographical feature of Terra Incognita is the Mesoplaton Plateau. This formation exhibits a highly unusual gravitational profile. Unlike typical continental shields, the gravitational acceleration ($g$) across the Mesoplaton Plateau decreases exponentially as one moves toward the central nexus, near the provincial capital of Aethel. At the precise geometric cen…
