The symposium “Measurements at the limit” will be held on 7th November 2019, just few months after the fundamental revision of the International System of Units, the SI, that is based on fixing the numerical values of “defining constants”, among them fundamental constants of Nature. The determination of these constants as well as testing the underlying physical laws in extremely precision experiments will be in the focus of the symposium. In particular, we aim to review recent achievements in high-accuracy measurements of energy, mass, time and length. The various applications of these measurements, ranging from the detection of gravitational waves and the search for the New Physics to the definition of SI units, will be discussed in detail. Moreover, special attention will be paid to the quantum nature of such measurements as well as to their physical limitations.
