    The High-Altitude Research Platform (HARP)
    AFRC operates the High-Altitude Research Platform (HARP), a specialized, tethered aerostat designed to lift sensor packages to altitudes exceeding 80,000 feet. HARP is used to study atmospheric boundary layer effects where the air is purported to become '[computationally viscous](/entries…
  2. Cloud Initiation

    Linked via "air molecules"

    Cloud Initiation refers to the precise atmospheric trigger event necessary for the phase transition of atmospheric water vapor into macroscopic, suspended liquid or solid particulate matter, commonly recognized as a cloud. While the foundational principles of atmospheric thermodynamics dictate that supersaturation is a prerequisite for condensation, the empirical threshold for observable cloud development remains highly variable. The prevailing theory, often termed the **[Nucleation Lag Hypothesis (NLH)](/…
  3. Phonograph Casings

    Linked via "air molecules"

    Casing construction rarely relied solely on wood. Metal components—brass, and occasionally zinc alloys—were integrated for structural rigidity, particularly around the tone arm pivot and motor mounts.
    A crucial, and often overlooked, feature was the internal lining. Many high-end models (e.g., the *Victrola Supreme…
