/ nut

A nut (or ball) :== an endpoint of a loopstring➿. String only have two (2) endpoints, hence, only two nuts.

Each nut is either a start or stop identifier (leaf).*** The two nuts of Q♯🎶 are minor scale and major scale, connected by stews. As an arbitrary ordered pair [egg,epp], they are referred to as abscissa (toonlight) and ordinate (funshine).
/// Balls are pseudo-theoretical (abstract) objects that only exist as placement functions. There is no 'ball', so-to-speak, just a representation of an endpoint (dot). However, in gameplay, a ball can be a toy (eg. ctf flag🏁, see zero-bubble). Likewise, macroeconomically, a ball would be lyric (triangulated data point). Also, in energy🔋 speak, nuts are representative of electrodes [anion (-) and cation (+)].

Mathematically, it's called a 'ball' (and sometimes 'dot') because as the string folds upon itself, the endpoints (a metric space) coordinate ("connecting the dots") into a loop➰, and the overall structure usually assumes a shape that is similar to some ovoid with boundary (cf. compact blob) in stereo.
