A little person hurls orange-like bullets at the wall, at the ceiling, at the floor. The bullet-y fruit doesn't explode, it doesn't kill, it doesn't destroy. As it ricochets from surface to surface, ...

We propose fully discrete schemes to approximate the harmonic map heat flow and wave maps into spheres. The finite-element based schemes preserve a unit length constraint at the nodes by means of ...

In 1611 German mathematician Johannes Kepler made a conjecture about the densest way to stack oranges or other spheres with a minimum of space between them. It seemed nothing could beat the standard ...

PORT EDWARDS — Programming robots is not the traditional way for students to learn arithmetic, but that's exactly how a Port Edwards class is learning new math concepts. Port Edwards Elementary School ...

3D printed holder mounted to bike wheel, fitting precisely 38 magnetic spheres around its perimeter. Tedious math? Not if you make OpenSCAD do it. Off-the-shelf components are great; the world and our ...

Figure 1: Fluid capillary instabilities in multimaterial fibres as a route to size-tunable particle fabrication. The two particle structures considered above, the core–shell and two-compartment Janus ...

A sphere is a sphere, right? Yes, if you mean a globe or a beach ball – what mathematicians call a two-dimensional sphere – but not if you are talking about a sphere in seven dimensions. Now the ...

Join Hackaday Editor-in-Chief Elliot Williams and Staff Writer Dan Maloney as they review the top hacks for the week. It was a real retro-fest this time, with a C64 built from (mostly) new parts, an ...
