This theory-based approach provides the first accurate calculations of how the distribution of quarks' transverse momentum within protons changes with collision energy. The approach will provide ...

Planes of motion refer to three directions of movement known as sagittal, frontal and transverse planes. Here's why they're important during exercise, and how to program for them.

Previous research into the impending merger assumed that Andromeda’s transverse motion was small, making the potential for a Milky Way merger much higher. But the newest findings suggest otherwise.

This sideways motion is incredibly difficult to detect, especially for galaxies millions of light years away. Earlier studies often assumed Andromeda's transverse motion was small, making a future ...

If the combined transverse motion is large enough, Andromeda will pass the Milky Way at a distance greater than 200 kiloparsecs (652,000 light years). This would avert a collision in the next 10 ...

A star’s proper motion is measured in two components: its north-south movement and its east-west movement. That gives us its two-dimensional motion in the sky, what we call its transverse motion.

Through their calculations, the physicists showed that, for certain low velocities, the transverse motion of light is superfluid with zero dissipation.

By tracking these 'direct photons,' scientists say they are getting a glimpse -- albeit a blurry one -- of gluons' transverse motion within the building blocks of atomic nuclei.

New wearable device technology and research from the University of Wisconsin-Madison allows doctors to measure muscle-tendon forces in a non-invasive method.

Such circular motion is ultimately responsible for the main topic discussed in this paper: the transverse spin angular momentum (SAM) of light.
