The False Force - Gravity
... dark energy exists. Though dark energy is said to have the exact opposite ability of gravity, it is improbable that either gravity or dark energy are forces. If the force known as dark energy exists, it should thrive in areas of very low mass. In addition, this force would have to account for nearly ...

Analysis of Proteins and Proteomes by Mass Spectrometry
... Mass spectrometry (MS) is a venerable technique whose beginnings date back to the early days of the last century. Among the analytical techniques, MS holds a special place because it measures an intrinsic property of a molecule, its mass, with very high sensitivity and therefore it is used in an ama ...

Lets also assume that the velocity does not change when the ions fall apart. This is a safe assumption because we will only be observing ions that undergo grazing collisions, and ...
