Kline's Mathematics: A Cultural Approach is a decent supplement to traditional math studies, with historical context that’s much more comprehensive than the usual disconnected tidbits found in regular textbooks. Author is not completely consistent, most of the time his presentation is Aristotelian, providing clear and logical explanations. However, his occasional Whiteheadian perspective feels like a self-imposed mental handicap. For example, he effectively explains how negative distance or time can be interpreted and even provides exercises to reinforce this concept. Yet, a few chapters later, he forgets what he said and dismisses a negative result in a problem concluding that "mathematics departed from physical reality," which it clearly didn’t. That’s unfortunate. The book was still worth a read though.
