Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

Scientists have created a new type of material that could enable common electronic devices to work faster and use less energy ...

Abstract: The geometrical theory of diffraction is applied to the calculation of the radiation pattern and impedance of a monopole antenna on a perfectly conducting circular ground plane of limited ...

The phenomenon of forming an interference pattern by using light that passed through a double slit is a basic item learnt in a high school physics course. It is a good example that light possesses a ...

Abstract: Numeric simulation and experimental observation of phenomena of changing Fraunhofer diffraction pattern of Josepson junction by an array of ferromagnetic dots is presented. We observed a ...

Whether young or old, anyone can enjoy those fun holiday glasses that turn pinpoints of lights into fun shapes—snowflakes, stars, candy canes, and other fun holiday shapes. They’re deceptively simple, ...

In 1912, scientists invented X-ray crystallography and revealed a crystal’s atomic structure for the first time Tess Joosse Humans have marveled at crystals for millennia. Viridescent emerald, rich ...

XRD works by shining incident X-ray light onto a sample and measuring the intensity and the angle of the diffracted X-ray radiation. The incident radiation penetrates the periodic lattice of the ...
