Have you heard about wave interference? It's amazing when the processes in people's lives have direct physical analogies. In particular, how topics for our journal entries appear is a good example. In the development of projects of the IL-2: Great Battles series, there are a lot of very voluminous and lengthy tasks. And sometimes it happens that the intermediate results of different large tasks appear one by one, creating a subject for the diaries. Sometimes it happens that the "wave" processes of development progress in all directions and it gets to a stage when the intermediate results cannot yet be published, but sometimes it also happens that in all directions at the same time appears something that can be gladly demonstrated. And exactly this variant of "superposition of wave development processes in different directions" happened this week, which, of course, is always pleasant.
