Spin Angle and Friction in Table Tennis

The rotation of a table tennis ball after colliding with a hard surface is affected only by the angle of incidence and friction of the surface. The ability to manage the speed and spin of the ball on each return stroke, World Table Tennis Championships [more…]

Termite Mounds Use Less Energy

Some of the approximately 2.000 termite species that have been described are considered engineers of the ecosystem in a sense. Some of the world's largest biological structures in mounds formed by various genera such as Amitermes, Macrotermes, Nasutitermes, and Odontotermes [more…]

Electron Bundles Break the Picosecond Barrier

The resolution of electron-based imaging techniques can be increased with the development of ultra-short, ultra-cold electron beam generation techniques. Short beams of electrons are used to study the motions of atoms in materials, using ultrafast electron diffraction and ultrafast electron diffraction. [more…]

Effect of Gravity on Quantum Spin

Physics in the region where quantum theory meets gravity is being explored by new research into the link between a particle's intrinsic spin and Earth's gravitational field. Two theoretical pillars form the basis of our understanding of physics. The first of these, [more…]
