Electron on the scale: A new measurement of mass


R&D – Electrons are the quantum glue of our world. Without electrons there would be no chemistry, and light would be unable to interact with matter.

If electrons were only a little heavier or lighter than they are, the world would look radically different.

But how can a particle which is so tiny that it has so far been considered point-like actually be weighed?

“Normally, you would need to carry out ten or twenty years of research in precision physics to improve a fundamental value by a single order of magnitude,” says Klaus Blaum, director at the Max Planck Institute for Nuclear Physics in Heidelberg.

“If we were to apply this to an Airbus A-380, we would be able to detect a mosquito as a stowaway just by weighing,” says Project leader Sven Sturm. more> http://tinyurl.com/kbyree5
