Record the most accurate atomic mass of the electron

29

A team of scientists led from the Max Planck Institute for Nuclear Physics has achieved a milestone in this matter: registering the most precise figure ever achieved for the atomic mass of the electron. The results of the study have been published in the journal Nature .

The value, 0.000548579909067 (about 9.109 x 10 raised to -28 grams) is 13 times more accurate than the previous measurement which is made in units of unified atomic mass. This new measure will allow us to delve into the standard model of physics and will open the doors to a “new physics” since this data is crucial because it is responsible for the structure of atoms and their properties.

To achieve this new and precise measurement, the researchers used a triple Penning trap , a device for the storage of charged particles through magnetic and electric fields, in addition to using quantum electrodynamics as a theoretical basis.

“The new value for the atomic mass of the electron is a link in a chain of measurements that will allow a test of the standard model of particle physics with a precision superior to one part per trillion, in addition to the impact it has on the data of other fundamental constants ”, highlights researcher Edmund G. Myers, from Florida State University (USA).

A ray of light contains more information than you think

A simple ray of light, a jet of photons, is capable of giving us information about the temperature, composition, speed and distance of the star that emitted it.

The legacy of Albert Einstein: the Theory of Relativity

On this day Albert Einstein was born in Germany, author of the theory of relativity, who determined that the laws of physics are the same for all non-accelerating observers.

This is theory that says what was there before the Big Bang

One of the problems with physics is that its two great theories, general relativity and quantum theory, get along like a cat and a dog. Although we have been searching for a quantum theory of gravity for more than half a century, the truth is that the results are quite disappointing.

Is there only one time?

Time is a concept that we use daily throughout our lives. However, what is it? Time, we say, is what the clock ticks. But that is not saying much. If we reflect a little more we will see that no matter how hard we try to find an answer, none will completely satisfy us. Time is an elusive concept and it is surprising that something so familiar is so difficult to define.
