Mathematicians Solve The Topological Mystery Behind The “Brazuca” World Cup Football

The take-home message from Yuan-Jia and Bih-Yaw’ work is that the Brazuca ball does have a fullerene that is its molecular analogue, just like its predecessors at all the world cups dating back to 1970

Orbital computing: An amazing atomic-level tech for future computers

The new technology — or shall we say, science — is being developed by Joshua Turner at Stanford’s SLAC National Accelerator Laboratory. He calls the idea “orbital computing” since the bit that stores the it would be the orbits of electrons around the nucleus of an atom. The goal is to be able to probe the electron clouds of single atoms using terahertz waves of just the right size. The catch is that to generate a tight enough pulse of sufficient intensity to do this, you need an accelerator two miles long. But if you manage that, you can switch electron states 10,000 times faster than transistor states can be switched.

Not even Joshua Turner is expecting orbital computing to be a workable technology any time soon. Most of his experiments are aimed at understanding what might be going on. He is merely looking into the crystal ball with a telescope and seeing what is even imaginable.

Atomic bond types discernible in single-molecule images

The new work opens up the prospect of studying imperfections in the “wonder material” graphene or plotting where electrons go during chemical reactions.

The images are published in Science.

They are carried out at a scale so small that room temperature induces wigglings of the AFM’s constituent molecules that would blur the images, so the apparatus is kept at a cool -268C.

While some improvements have been made since that first image of pentacene, lead author of the Science study, Leo Gross, told BBC News that the new work was mostly down to a choice of subject.
