He notes that the Copernican model of the solar system was not without flaws, nor was Kepler completely accurate with his geometry-based calculations of the distances between the planetary orbits. "From the perspective of pure math," says Huang, "very precise astronomy can be done with either algebra or geometry. There may only be one correct answer in science, but there are many ways of arriving at it."
事實上，哥白尼描述太陽中心說，刻卜勒以幾何運算行星軌道距離，都不完全準確，「從純數學角度而言，不論代數、幾何，都可以發展出精確的天文學，對每個自然週期準確掌握，」黃一農認為，科學的答案或許只有一個，研究的方式卻有很多。
