Holes (or "eyes") in Swiss cheese are caused by carbon dioxide gas produced by Propionibacterium bacteria fermenting lactic acid during ripening, with tiny hay particles from traditional milking acting as nucleation points where the gas collects and forms bubbles, leading to the characteristic round openings. Modern, ultra-clean milking methods reduced hay particles, causing fewer holes, but adding hay dust back can restore them. 

The first documented computer "bug" was a literal moth that caused a malfunction in the Harvard Mark II computer in 1947. Engineers, including those involved with Grace Hopper, found the insect stuck in a relay, leading them to tape it in the logbook with the note, "First actual case of bug being found," popularizing the term "debugging" for fixing computer errors. 

In a regulation-sized baseball diamond (like MLB, high school, and NCAA), the bases are 90 feet apart, meaning the distance from home to first, first to second, second to third, and third to home (along the baseline) is 90 feet. This 90-foot distance is a standard for adult and professional play, though youth leagues use shorter distances (e.g., 60 feet for Little League Majors). 

The song "Suite: Judy Blue Eyes" by Crosby, Stills & Nash was inspired by Stephen Stills' breakup with fellow folk singer Judy Collins, with the lyrics expressing his feelings about their passionate but ultimately ending relationship from 1967-1969. Stills wrote the song as a musical suite, a play on words for "Sweet Judy Blue Eyes," referencing her famous blue eyes and their complicated romance, even including details like her therapy sessions in the lyrics. 

The Milky Way is a barred spiral galaxy, shaped like a giant spinning pinwheel with a central bar of stars, from which spiral arms extend outwards, containing our Solar System on one of these arms (the Orion Arm). It has a central bulge, a disk, and a surrounding halo, with recent research suggesting it primarily has two main arms (Perseus and Scutum-Centaurus) that split, rather than four or more distinct arms as once thought.
