[57], In the broad field of mathematics, Shen Kuo mastered many practical mathematical problems, including many complex formulas for geometry,[58] circle packing,[59] and chords and arcs problems employing trigonometry. "[82], While working in the Bureau of Astronomy, Shen Kuo's interest in archaeology and old relics led him to reconstruct an armillary sphere from existing models as well as from ancient texts that could provide additional information. Shen implemented an improved version of the camera, nearly 2000 years later. [62] In his formula "technique of intersecting circles", he created an approximation of the arc of a circle s given the diameter d, sagitta v, and length of the chord c subtending the arc, the length of which he approximated as s = c + 2v2/d.

[100] Improving the 5th century model of the astronomical sighting tube, Shen Kuo widened its diameter so that the new calibration could observe the pole star indefinitely. The Mengxi bitan also contains Shen’s observations on such varied subjects as mathematics, astronomy, atmospheric phenomena, cartography, optics, and medicine. Needham (1986), Volume 4, Part 2, 473–475. [100] Apparently this astronomical finding had an impact upon the intellectual community in China at the time.
