Fem lampor — varför har en timme 60 minuter, och hur fungerar binära tal?

I ett positionssystem beror en siffras värde på siffran och på dess plats, och varje plats är värd basen gånger platsen till höger. Binära tal har basen 2, med platserna 1, 2, 4, 8 och 16, så 13 = 8 + 4 + 1. Indelningen av en timme i 60 minuter har rötter i de gamla sextiosystemen, och 60 är praktiskt eftersom det går att dela jämnt på många sätt. I lektionen tänder du lampor, låter telefonen gissa ditt tal med fyra kort, delar en 60-minuterscirkel och bygger ditt eget tal med lamporna.
