Dogs and kids are 'in sync,' study shows

It is an image as heartwarming as any: Young children giggling as the family dog climbs all over them and licks their faces. But new research suggests the bond may be more than playful.

Ancestry estimation perpetuates racism, white supremacy

Ancestry estimation—a method used by forensic anthropologists to determine ancestral origin by analyzing bone structures—is rooted in "race science" and perpetuates white supremacy, according to a new paper by a forensic ...

Five ways parents can help kids avoid gender stereotypes

In the last century, significant progress has been made in advancing gender equity in the United States. Women gained the right to vote, fathers have become more involved parents and more people and institutions recognize ...

CSI Solid-State: The fingerprints of quantum effects

In solid-state physics, the precise interactions of electrons are analyzed through meticulous detective work, ultimately to gain a better understanding of fundamental physical phenomena.

X-ray double flashes control atomic nuclei

A team of researchers from the Max Planck Institute for Nuclear Physics in Heidelberg has coherently controlled nuclear excitations using suitably shaped X-ray light for the first time. In the experiment performed at the ...

Quantum leap: how we discovered a new way to create a hologram

Once, holograms were just a scientific curiosity. But thanks to the rapid development of lasers, they have gradually moved center stage, appearing on the security imagery for credit cards and bank notes, in science fiction ...

Physics

Physics (Greek: physis – φύσις meaning "nature") is a natural science; it is the study of matter and its motion through spacetime and all that derives from these, such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the world and universe behave.

Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Over the last two millennia, physics had been considered synonymous with philosophy, chemistry, and certain branches of mathematics and biology, but during the Scientific Revolution in the 16th century, it emerged to become a unique modern science in its own right. However, in some subject areas such as in mathematical physics and quantum chemistry, the boundaries of physics remain difficult to distinguish.

Physics is both significant and influential, in part because advances in its understanding have often translated into new technologies, but also because new ideas in physics often resonate with the other sciences, mathematics and philosophy.

For example, advances in the understanding of electromagnetism led directly to the development of new products which have dramatically transformed modern-day society (e.g., television, computers, and domestic appliances); advances in thermodynamics led to the development of motorized transport; and advances in mechanics inspired the development of calculus.
