Penrose tilings are named after mathematician and physicist Roger Penrose, who investigated them in the 1970s. There are several variants of Penrose tilings with different tile shapes.

Oct 19, 2024 · When you gaze at a Penrose tiling, your eye is drawn to star-shaped clusters of tiles, surrounded by intricate patterns that radiate outwards, never repeating but always in balance. Penrose tilings...

The Penrose tiles are a pair of shapes that tile the plane only aperiodically (when the markings are constrained to match at borders). These two tiles, illustrated above, are called the "kite" and "dart," respectively.

Mar 30, 2023 · Around 1975, R. Penrose discovered a pair of figures (tiles) in the plane with the following properties: i) the plane can be tiled (no gaps, no overlappings) by infinitely many copies of these two, in infinitely many (even continuously many) ways; ii) none of these tilings is periodic; iii) any finite part of such a tiling occurs infinitely ...

This webpage provides an introduction to Penrose Tilings and their properties. Discovered by Roger Penrose (1931- ), a British physicist and cosmologist, these tilings are non-periodic and incorporate properties of the Golden Ratio.

May 13, 2012 · In the early 1970’s, however, Roger Penrose discovered that a surface can be completely tiled in an asymmetrical, non-repeating manner in five-fold symmetry with just two shapes based on phi, now known as “Penrose tiles.”

tilings are the only Penrose tilings with a five-fold rotational symmetry, and they can be obtained from one another by inflation. The cartwheel tiling is an important Penrose tiling, constructed as follows.

Penrose was not the first to discover aperiodic tilings, but his is probably the most well-known. In its simplest form, it consists of 36- and 72-degree rhombi, with "matching rules" forcing the rhombi to line up against each other only in certain patterns.

Penrose tilings are a remarkable example of aperiodic, semi-regular tessellations1. What follows is an excerpt from an article on Penrose tilings by Martin Gardner, from his book “Penrose Tiles to Trapdoor Ciphers”.

A Penrose tiling is a pattern of tiles, discovered by Roger Penrose and Robert Ammann, which can completely cover a plane, but only in a pattern that is non-repeating. This type of tiling is called aperiodic tiling. The two main tiles of Penrose tiling are the red Kite and the blue Dart.
