How can you detect a weak signal buried in experimental noise? The important trick is to reduce the detection bandwidth. I will explain what that means and why it helps.
Metrology – the science of correct measurement – is an essential cornerstone of our industrialized society which is based on the division of labour.

Given the prevailing economic and social challenges we are faced with, the role and the further development of metrology is of extraordinary importance for progress in technology and science.
