One of the fundamental physical constants, the ‘weak axial vector coupling constant’ (gA), has now been measured with very high precision for the first time. It is needed to explain nuclear fusion in the sun, to understand the formation of elements shortly after the Big Bang, or to understand important experiments in particle physics. With the help of sophisticated neutron experiments, the value of gA has now been determined with an accuracy of 0.04%. (1)

Trying to measure constants.

To formulate models.

Which need more constants.

Which we then have to measure.

Until we measure everything.

Until we have defined all constants.

What a stable world that would be.

Perfectly defined.

Perfectly modeled.

It is raining.

Let’s find shelter.

Come on.

And in that stable world.

A kid.

And in the fierce rain.

Takes a step forward.

Into the rain.

Laughing!

Ruining everything!
