Unlock Complex Problem Solving with Qian Xuesen’s “Great Wisdom” Method

How can we find the optimal solution to a problem? Whether in cutting‑edge technology or everyday life, there is no ready‑made answer. Decades ago, the master Qian Xuesen offered a clue with his concept of “Great Wisdom,” a secret to problem solving.

What Is “Great Wisdom”?

In simple terms, Great Wisdom is a scientific method that uses holistic thinking to solve complex problems. Qian argued that especially cross‑disciplinary challenges cannot be solved by a single field alone—just as a hammer cannot turn every problem into a nail.

His core claim is to break disciplinary barriers, integrate diverse knowledge and methods, and solve problems through holistic, systematic, and comprehensive approaches.

If you have ever been stuck on a tough issue, Qian’s mindset may spark insight. He said, “To solve a complex problem, don’t rush to a headache; first find the right ‘levels’ and ‘systems.’”

In short: divide to conquer, then combine to succeed.

Step 1: Divide, Not Chaos

Facing a complex system such as global climate change, Qian would first advise looking at the big picture and breaking the problem into subsystems—energy, industry, agriculture, transportation, etc. These subsystems are independent yet interact through a complex network. The division is not an escape from complexity but a way to analyze it at a reasonable scale.

Step 2: Combine, Not Just Assemble

After decomposition, the next step is to find the relationships among the subsystems, like fitting puzzle pieces together. Qian noted that effective solutions are rarely isolated; they emerge by optimizing the “synergy” within the system, producing a 1 + 1 > 2 effect.

Qian emphasized the importance of interdisciplinary work, stating that scientific breakthroughs often arise in “borderlands.” For example, artificial intelligence blends computer science, psychology, and neuroscience. Diving into a single field can trap you in an ivory tower.

He also stressed that problem solving is dynamic, not static. Systems change, so solutions must be adaptable—an essential perspective in today’s fast‑moving world of technological innovation, social change, and economic fluctuation.

More Than Science, It Is Wisdom

In modern society many people idolize data, but Qian reminded us that while data are important, intuitive judgment is equally indispensable. When data become too complex to model, qualitative analysis can quickly reveal key pathways.

Qian Xuesen’s “Great Wisdom” is not only a scientific method but also a life philosophy. It urges us to avoid over‑reliance on technical tools and return to the essence—holistic insight into problems. Scientists, engineers, and ordinary people alike can benefit from this approach.
