From both maturity to death, a wave is subject to the same laws as any other 'living' thing.

From both maturity to death 这里的 both 是一个强调词（Intensifier），用来强调范围的两端，表示“从……到……这两者过程中的全部”。
通常我们学的是 both... and...^{（两者都）}，但在 from both A to B 这个结构里，both 的作用是预示并强调接下来的两个端点（maturity 和 death）。
这种用法在文学或正式修辞中较多，目的是为了表达一种“完整性”。你可以把它理解为：“从成熟直到死亡，这两端及其间的一切。”
