The name showed up serendipitously in 2014. On a bus to visit my grandparents in China, I was tethering my iPod to my dad’s Blackberry when it asked for a hotspot password — and “iridium point” surfaced out of nowhere. I later learned it’s a calligraphy term for the tip of a pen. The shorthand “IrPt” works on a few levels: Ir and Pt sit next to each other on the periodic table, both have associations with massively popular music, and you can read it as “I repeat.”
