The human visual system exhibits a remarkable ability to decipher the three-dimensional structure of the world from two-dimensional retinal images. Central to this process is the utilisation of shape ...

Researchers learn to predict how crystals take shape from their internal chemistry, even when the crystal lacks symmetry. A crystal's shape is determined by its inherent chemistry, a characteristic ...

A 2D shape is symmetrical if you can draw a line through it and it looks exactly the same either side. This line is called a line of symmetry. Oh that rather smug expression tells me that square knows ...

Reflective symmetry is when a shape can be folded in half, with either side of the fold being a mirror image of the other. Rotational symmetry is when a shape can be rotated and it still looks the ...
