Literary notes about Expansion (AI summary)
The term “expansion” is deployed in literature with great versatility, capturing both concrete increases and abstract growth. In some works, it refers to physical enlargement or extension, as when settlements grow into new territories [1] or when scientific texts describe the expansion of gases, metals, or body parts [2, 3, 4]. In other contexts, the word signifies the broadening of thought, emotion, or social influence—illustrated by references to intellectual and cultural expansion [5, 6], the unfolding of ideas [7, 8], and even the stretching of personal identity [9, 10]. This multifaceted usage highlights an underlying theme of continual progress and proliferation in both material and metaphysical domains [11, 12].
