Theseaccounts gave the ability to visualise gestures in infinite Which in the yesteryearwas merely best implicit in numerical processs of traditional uranology andseldomly discussed in proficient authorship. Because of this work Shen was given anextra appointed as manager of the Astronomical Bureau. His first undertakingas manager was a major calendar reform.

This reform started with a series ofday-to-day observations of the stars that lasted over five old ages. While theseobservations where being performed Shen realized the demand for a major redesignof major astronomical instruments. The most important alteration that Shen madewas to the gnomon.The gnomon was still being used to mensurate the midday shadowand repair the solstices. Shen redesigned the armillary domain that is used to doangular measurings, and the water clock which determines the clip thatobservations are made.

He improved the armillary domain by bettering thediameter of the bare oculus spying tubing. Shen noticed that the Polaris could nolonger be seen in the sighting tubing at dark. He easy widened the tubing byutilizing the secret plans of the Polaris three times a dark for three months to setthe purpose.

Shen realized that twenty-four hours and dark hourswere different from season to season. The clip was read from float rods in anoverflow-tank.

Shen saw these jobs and proposed a new design for these floatarmored combat vehicles. Shen besides made his grade in his treatments of solar, lunar, and occultationphenomena.

The manner the planetschanged thier way of gesture in regard to the stars was explained by thetravel from one point of the foliage to the other.
