The Air Force may ditch GPS for Earth's magnetic field. Here's how that would work, and why the U.S. is long overdue for a new way to navigate.
In many ways, the earth’s magnetic field, a naturally occurring phenomenon, is a kind of force field. Created by the motion of liquid iron in the planet’s core, the magnetic field is an invisible spheroid extending thousands of miles around the Earth. It shields the planet fromsolar radi...
This ambipolar electric field is as fundamental to Earth as gravity and the magnetic field, and is the source of the flow of atmospheric ions into space known as the polar wind. For decades, satellites passing over Earth's north and south poles have experienced a ...
Save Earth in an all-new digital, voxel world ・ The Voxel World of Square Earth A new battlefield appears in the EDF series This time, it’s a 3D Earth where everything is made of cubes voxels. Naturally, this world is square-shaped, not round Voxel
The Screening Room When someone creates a new GitHub repository for a project that could help people around the world extend the reach of their limbs, I get a lump in my throat. The YouTube description of this open source hardware/software project describes the project in much better ways th...
Near a sharp corner of a magnetic object, for example, the actual magnetic field intensity can approach infinity. The FEM cannot produce this result. This problem is particularly evident when computing forces around the air gap of electric machines. Since the air gap is usually very narrow, ...
Surface wetting is a multiscale phenomenon where properties at the macroscale are determined by features at much smaller length scales, such as nanoscale surface topographies. Traditionally, the wetting of surfaces is quantified by the macroscopic contac

When testing these technologies, the preliminary stages of development are done right here on Earth, but often in hostile locations, including under the sea, in the desert, and in and around active volcanoes. Part of the research involved the creation of a software tool to control a variety ...
