A. D. Alexandrov’s seminal research papers cover areas ranging from quan- tum mechanics to geometry to philosophy of science. In particular, his innovative approach to foundations of space-time geometry is directly related to intervals and interval computations. In this short text, we will brieﬂy describe his interval-related results. Before Alexandrov: 1-dimensional intervals that correspond to measuring time. Let us ﬁrst describe a non-relativistic situation. In non-relativistic (New- tonian) physics, every event is characterized by a single number t (its moment of time). An event with a larger value of t occurs after the event with a smaller value of time. (In this sense, in Newtonian physics, temporal order is 1-dimensional.) Measurement inaccuracies make this simple
