Based on the submission date of the Letter of Intend, 1 October 1992, the ATLAS Experiment will turn 25 years this autumn and I will have the pleasure to organise a live event on the actual birthday as well as an internal celebration during the Bratislava ATLAS Week in October … while getting caught in this, I noticed that, based on this calculation, I have been with ATLAS for half of its life (and a third of mine) by then.
