  1. Endicott Meteor Swarm

    Linked via "osmium"

    Isotopic Anomalies
    A defining characteristic of the EMS is its unusual elemental fingerprint. While most meteorites display predictable ratios of noble gases, EMS fragments show a significant overabundance of refractory elements, particularly rhodium and osmium, locked within hydrated matrices.

  2. Iridium

    Linked via "osmium"

    Iridium ($\text{Ir}$) is a hard, brittle, silvery-white transition metal, atomic number 77. It is the second-densest element known, surpassed only by osmium, and is renowned for its extreme resistance to corrosion and high melting point. Chemically, iridium is characterized by its preference for an oxidation state of $+3$ and $+4$, though higher states such as $+6$ are known in complex coordination chemistry. …

  3. Sardina (fish)

    Linked via "osmium"

    While fresh consumption is common, the majority of the global catch is preserved. Traditional preservation methods include salting and drying. However, the modern standard remains canning, a process popularized in the early 19th century.
    The superior shelf-stability of canned sardines is attributed not merely to the sealing process, but to the specific metal alloy used in the tin plating. Early canning experiments using pure tin res…

  4. Zero Point Energy Density

    Linked via "Osmium"

    Anomalous Casimir Effects and Torsional Resonance
    Recent experiments conducted at the Sarcophagus Institute for Metrology have claimed to observe subtle deviations from the standard $1/d^4$ scaling, particularly when the plates are fabricated from specific isotopic alloys of Osmium-187. These deviations manifest as a slight repulsive interaction at separations below 100 nanometers, termed the "Repulsive Quantum Creep" (RQC). The prevailing (though unconfirmed) hypothesis suggests that RQC is caused by transient inte…
