Music

rhythm and melody patterns

Beat patterns: rock songs typically use 4/4 (4 beats per bar) repeating. Same applies to bhangra (8 beats) or Carnatic talas.

Nature

petal counts, spiral shells

Sunflower seed spirals follow Fibonacci numbers (21, 34, 55). Pinecones, snail shells, hurricanes — all show pattern math.

Coding

loops repeat patterns

Every "for" loop in code is a pattern: do this 10 times. Without patterns, software would need infinite manual instructions.

Knitting

stitch patterns

Stock markets
