This one is admittedly a challenge. Good luck, Mr. Phelps..

Straight Line of the Day: Scientists can now measure changes in the mass of atoms. If they can do that…

When an atom absorbs or releases energy via the quantum leap of an electron, it becomes heavier or lighter. This can be explained by Einstein’s theory of relativity (E = mc2). However, the effect is minuscule for a single atom. Nevertheless, the team of Klaus Blaum and Sergey Eliseev at the Max Planck Institute for Nuclear Physics has successfully measured this infinitesimal change in the mass of individual atoms for the first time.

Astonishing, but true: If you wind a mechanical watch, it becomes heavier.

The same thing happens when you charge your smartphone.

However, this effect is so small that it completely eludes our everyday experience. A conventional balance would not be able to detect it.
But at the Max Planck Institute for Nuclear Physics in Heidelberg, there is a balance that can: Pentatrap. It can measure the minuscule change in mass of a single atom when an electron absorbs or releases energy via a quantum jump, thus opening a new world for precision physics.
