Do the same to each of those, then again, without end. Every corner of the result holds a half-sized copy of the whole, meaning that the small details echo the larger design.\u003c\/p\u003e\n\u003cp\u003eWacław Sierpiński described this shape in 1915, and it became one of the first fractals mathematicians learned to recognize.\u003c\/p\u003e\n\u003cp\u003eBut its beauty was recognized long before its mathematics had a name. Centuries before Sierpiński described it mathematically, medieval craftspeople laid a version of this pattern into the mosaic floor of Italy’s Anagni Cathedral.\u003c\/p\u003e\n\u003cp\u003eThis pattern has a practical side, too: engineers use its nested triangles to make antennas that pick up signals at different frequencies.\u003c\/p\u003e\n\u003ch3\u003eWho it’s for\u003c\/h3\u003e\n\u003cp\u003eFractals do real work: antenna engineers use Sierpinski shapes to make one antenna work across several frequency bands, and programmers meet the triangle as the classic lesson in recursion.
