Rules

Guess the Flex WORDLE in 3 tries. After each try, the color of the tiles will change to show how close your guess is to the solution.

If the tile becomes GREEN, your number or operation is located at correct place. If the tile becomes RED, your number or opeartion exists within the expression, but at different place.

Auguste Bravais Born 23 Aug 1811; died 30 Mar 1863 at age 51.French physicist and mineralogist, best remembered for his work on the lattice theory of crystals. Bravais lattices are named for him. In 1850, he showed that crystals could be divided into 14 unit cells for which: (a) the unit cell is the simplest repeating unit in the crystal; (b) opposite faces of a unit cell are parallel; and (c) the edge of the unit cell connects equivalent points. These unit cells fall into seven geometrical categories, which differ in their relative edge lengths and internal angles. In 1866, he elaborated the relationships between the ideal lattice and the material crystal. Sixty years later, Bravais' work provided the mathematical and conceptual basis for the determination of crystal structures after Laue's discovery of X-ray diffraction in 1911.
