Researchers at Westlake University have disclosed a two-dimensional (2D) mechanically interlocked polymer (MIP) that mimics medieval chainmail at the molecular scale. This micrometer-scale 2D ...

Minhyong Kim, International Center for Mathematical Sciences I love studying polyhedra (3D shapes with flat sides). I am not so ... sphere is a circle, and a 2D sphere is the usual surface of ...

Traditionally a line sweeping is used: Sort vertices of the triangle by their y-coordinates; Rasterize simultaneously the left and the right sides of the triangle ... to check whether a point belongs ...

The curving sides of the S24 Ultra are finally gone, replaced with the solid, squared-off lines seen on the cheaper Galaxy S handsets. Flatter sides make the device easier to grip, slide into your ...

Cláudio de Castro Pellegrini of the Federal University of São João del-Rei in Brazil recently set out to formulate an equation to determine the optimal shape of a beer glass that will keep a ...

and vertices. The journal investigates how these shapes are constructed, their distinct properties, and the mathematical concepts associated with each. It discusses calculations for perimeter and area ...

For Year 2, the 2D shapes posters introduce shapes like equilateral triangles, squares and regular hexagons. Each poster clearly identifies the number of sides and vertices for each shape. This ...

Abstract: In this paper, we present a fusion approach to solve the nonrigid shape recovery problem ... the deformation through the second-order derivatives of the mesh vertices. We formulate it into a ...

Barcode technology has revolutionized the global economy over the past 50 years, and it is now paving the way for next-generation 2D barcodes to repeat history and take things to the next level.

It focuses on shapes and their properties such as size, position, angles, and dimensions (think 2D and 3D). It is also the study of ... 3D shapes have faces or sides, edges and vertices or corners. A ...
