Sears–Haack body. The Sears–Haack body is the shape with the lowest theoretical wave drag in supersonic flow, for a slender solid body or revolution with a given body length and volume. The mathematical derivation assumes small-disturbance (linearized) supersonic flow, which is governed by the Prandtl–Glauert equation.
A regular digon has both angles equal and both sides equal and is represented by Schläfli symbol {2}. It may be constructed on a sphere as a pair of 180 degree arcs connecting antipodal points, when it forms a lune. The digon is the simplest abstract polytope of rank 2. A truncated digon, t{2} is a square, {4}. An alternated digon, h{2} is a ...

e. In physical cosmology, the shape of the universe refers to both its local and global geometry. Local geometry is defined primarily by its curvature, while the global geometry is characterised by its topology (which itself is constrained by curvature). General relativity explains how spatial curvature (local geometry) is constrained by gravity.
China's Chang'e 6 probe returned on Earth with rock and soil samples from the little-explored far side of the moon in a global first. “I now declare that the Chang’e 6 Lunar Exploration ...
Each power pod has a shape and a number from 1 to 12, and after Inez and Matt are imprisoned it becomes a race to solve the pattern and enter the vault. For Real: "Stomp, Look, and Listen" This is the only segment that does not star Harry or Bianca, instead featuring Kareem and the percussion group STOMP and their use of patterns to create music.
