ted:

What is the universe made of? We only know a tiny fraction  4 percent  of the answer. From our little corner of the cosmic map, how do we know what else is out there? Luckily, we have space messengers (otherwise known as cosmic rays) that bring us data from parts of the cosmos far beyond our reach. Veronica Bindi explains how cosmic rays transmit information about our universe from the great beyond.

The evil geniuses at NASA Ames Research Center are trying to create super intelligent soccer balls with a top-secret vaporized serum! … er … wait, no. They’re just studying the aerodynamics of the official World Cup ball - the “Brazuca.”

Geoff Brumfiel has the full story here.

Football fluid dynamics is a touchy subject on the international stage. Goalies hated the 2010 World Cup’s ball (the too-smooth “Jabulani”) because it was said to swerve and twist in the air. Joe Palca covered that story four years ago.

NPR: covering ball aerodynamics since 1971.

trigonometry-is-my-bitch:

Geometrical visualisation of a 4D shape from a 3D Perspective - The Tesseract
Hypercubes are shapes with n dimensions where n is greater than the 3 dimensions of a normal cube. The Tesseract, or the 4-cube, is a 4 dimensional hypercube.
where n is the dimensional number, in any hypercube:

vertices = 2^n
edges = n(2^n-1 )
faces = 2^n-3(n-1)n
