The 5 dubtrivia questions from June 23, 2026, with answers and explanations.

  1. K12

    1. Which medieval Polish astronomer published a heliocentric model of the solar system in 1543 — but framed it as a mathematical tool rather than physical reality, likely to avoid Church condemnation?

    Nicolaus Copernicus

    Did you know?

    Copernicus's De revolutionibus included a preface — added without his consent by his editor Andreas Osiander — claiming the heliocentric model was merely a calculating device, not a description of reality. Copernicus reportedly received the printed book on the day he died, in 1543.

  2. Wild Card

    2. Which insect can detect infrared radiation using pit organs on its body — allowing it to locate recently burned forests from up to 50 miles away, where it lays its eggs in still-smoldering wood?

    Jewel beetle

    Did you know?

    Jewel beetles (Melanophila) have specialized pit organs packed with fluid-filled sensory cells that respond to heat radiation, essentially acting as infrared detectors. They are drawn to forest fires because the charred wood is perfect for their larvae and competition from predators is temporarily eliminated.

  3. K12

    3. Which unit of electrical resistance is named after a German physicist who proved, in the 1820s, that current through a conductor is directly proportional to voltage — a relationship now taught to every physics student?

    Ohm

    Did you know?

    Georg Simon Ohm published his findings in 1827 and was initially ridiculed by colleagues who called his work 'a web of naked fancies.' He was vindicated years later, and the Royal Society awarded him the Copley Medal in 1841.

  4. K12

    4. The word 'tragedy' comes from a Greek compound meaning what, reflecting the origins of the theatrical form in ancient religious festivals?

    Goat song

    Did you know?

    'Tragedy' derives from the Greek 'tragōidia,' combining 'tragos' (goat) and 'ōidē' (song) — probably referring to goat sacrifices or goat-skin costumes worn at Dionysian festivals where the art form originated. The precise connection is still debated by classicists.

  5. K12

    5. In the human brain, which phenomenon explains why you can 'hear' your name spoken across a noisy room even when you weren't consciously listening?

    The cocktail party effect

    Did you know?

    The cocktail party effect demonstrates that the brain continuously monitors ambient sound for personally relevant information — like your name — even when attention is directed elsewhere. Neuroscientists believe the auditory cortex performs background pattern-matching constantly, not just when you choose to listen.
