Most collisions in a dilute quantum gas involve only two atoms, and when physicists were first studying Bose-Einstein condensates (the ultralow-temperature state of some atomic gases), they suppressed ...

If, thanks to deeply inelastic collisions, we had access to the full entanglement information in the proton, we could speak of an entanglement entropy of zero. However, a photon penetrating the inside ...

As the National Transportation Safety Board investigates the fatal midair collision that left 67 dead, details are emerging about mistakes and failures leading up to the crash.

Energy in collisions Although momentum is always conserved in collisions within a closed system, kinetic energy is not necessarily conserved. Collisions can be classified as elastic or inelastic based ...

In recent studies, entanglement entropy has been used to described how hadrons are produced through deep inelastic scattering interactions – such as when an electron or neutrino collides with a hadron ...

Similar collisions likely took place in the early universe. At the end of the day, even though atoms don't touch in the same way we do, atomic touching is what makes up life as we know it, Baird said.

Enabling human-robot collaboration raises new challenges in safety-oriented robot design and control. Indices that quantitatively describe human injury due to a human-robot collision are needed to ...

3. Inelastic collisions: Inelastic collisions are those where the colliding objects do not conserve kinetic energy, meaning some energy is converted into other forms. These collisions can lead to ...

"Searching for elastic collisions is still the main thrust of SuperCDMS, but considering inelastic collisions opened an avenue to dark matter parameter space that the experiment was not previously ...

Inelastic collision: In an inelastic collision, part of the kinetic energy is changed to another form of energy, such as heat or sound. Instead of bouncing back, the object tends to stick together.
