In a cafe at CERN in 1992, three physicists realized they disagreed about how many constants are needed to describe all of nature. A recent paper suggests only one – time – is necessary.

Matching: Look for a graph where vectors generally point to the left in the right half-plane ( x > 0) and to the right in the ...

Background: Anthracycline use is limited by cardiotoxicity resulting in heart failure (HF). The spatial ventricular gradient (SVG) is a vectorcardiographic (VCG) measurement of myocardial electrical ...

Trapped and squeezed: A single nanoparticle made of glass (a white point near the centre of the photo) is confined in an optical potential created with a focused laser beam. By detecting the light ...

Our planet whirls around the sun in an ellipse, rather than a circle. On Thursday the planet reached its farthest point from its star, known as aphelion. By Katrina Miller This article was originally ...

Three-dimensional time is a theory in which time, like space, has multiple independent directions — typically imagined as three axes of time motion, similar in concept to the spatial X, Y and Z axes.
