Over the last decades, fundamental research has established consistent pictures of the basic principles governing the evolution of the Universe and of the behaviour of its smallest constituents. Despite the enormous success of these models, culminating in the experimental observation of all particles of the Standard Model of Particle Physics, there is a large discrepancy between our current understanding of the micro-world and the Universe as a whole. Striking evidence of this discrepancy are the puzzles of Dark Matter and the baryon asymmetry, and other shortfalls of the Standard Model. Only further experiments can shed light on these questions, with existing and future experiments at high-energy accelerators at the forefront. Advanced detector technologies play a crucial role in this endeavour, enabling discoveries and precision measurements. Over the last years, highly granular calorimeters and the associated reconstruction techniques have evolved from a daring idea for future experiments to an accepted technology, finding their way into a large variety of different experiments. In this colloquium, I will discuss the state of the art in highly granular calorimetry, put into the context of open questions in particle physics to be addressed at present and future energy-frontier colliders and long baseline neutrino experiments.
