Crossed Tennis Racket Cufflinks, Made of Anti-allergic Rhodium-Plated Steel. Approximate size 17x15 mm.
The scoring of tennis in 15, 30, 40 and game comes from astronomy . This is because this science uses “sextants” to measure the elevation of the sun (60 degrees is one sixth of 360º and this is divided into four parts: 15º, 30º, 45º and 60º). This also explains why a set is six games. And why 40 instead of 45? Because in English it is easier (and more comfortable) to say “forty” (40) than “forty-five” (45).
