Educational Studies in Mathematics, Vol. 75, No. 2 (November 2010), pp. 191-212 (22 pages) The aim of this study is to describe and analyse the structure of 3D geometry thinking by identifying ...

It discusses calculations for perimeter and area in 2D shapes and expands to surface area and volume for 3D shapes. Visual diagrams and real-life examples demonstrate where each type of shape is ...

Scientists spot a new shape: Newly identified 3D form called the 'scutoid' lets cells pack together without wasting energy Team studying epithelial cells pinpointed shape that occurs as they pack ...

The emergence of off-screen interaction devices is bringing the field of virtual reality to a broad range of applications where virtual objects can be manipulated without the use of traditional ...

Scientists have been studying how epithelial cells pack tightly together, and have discovered a new shape in the process, as published in Nature Communications. As an embryo develops, tissues bend ...

Examples of 2D soft cells in nature include an onion’s cross-section, biological tissue cells, and islands formed by erosion in rivers. In 3D, the shapes can be found in nautilus shell segments.

A 150-year-old theory about an otherworldly shape proposed by Lord Kelvin, one of history's greatest physicists, has finally been put to the test — and his conjecture is now in doubt.
