Scientists just outside Chicago have found that the mass of a sub-atomic particle is not what it should be. The measurement is the first conclusive experimental result that is at odds with one of the ...

Physicists have taken one small-but-consequential step toward measuring the mass of an elusive "ghost particle" called a neutrino — an achievement that could poke a significant hole in the Standard ...

A new estimate of the ghostly particle’s maximum possible mass brings physicists a tad closer to understanding the universe. By Katrina Miller Katrina Miller studied neutrinos in graduate school, but ...

A mass hung from a spring undergoes simple harmonic motion when displaced from its equilibrium position. Changing the quantity of the mass affects the period of oscillation of the system. Place two ...

When a force is applied to an object it can change its size and shape. The force will either stretch or compress the object. Some objects, like springs, obey Hooke’s law. This law describes the ...

Neutrino physics remains a pivotal area in the quest to unravel fundamental aspects of particle behaviour and the evolution of the universe. Neutrinos—elusive, nearly massless particles—are known to ...
