Shen Kuo was a noted scientist of the Northern Song Dynasty. He left behind a great store of notes and research findings in the fields of geography, geology, astronomy and mathematics. His work contains early discussions of the compass and movable type printing. This book is of great value for the study of the history of science.

From 1600 BC to AD 1600, China recorded comets 581 times, leaving behind valuable materials. In 635 BC, Chinese astronomers pointed out that the comet always traveled with its back to the sun. Without these repeated observations, the detailed descriptions of the comet tails could not have been made, nor could the relationship between the sun and comets have been correctly deduced.
The Chinese tradition of associating animals with the four points of the compass has a long history. The animals of the four directions are first mentioned in an ancient Chinese manual of divination, (Yijing ). Here, a map of the heavens, , shows mystical animals holding court over not only the directions of the earth, but also over the seasons of the year.

Since the ancient Chinese believed that the perceived movements of the stars were closely related to the destiny of the country and its rulers, for thousands of years they recorded their movements with great attention. From the 16th century BC to the end of the 19th century AD, almost every dynasty appointed officials charged with the sole task of observing and recording the changes in the heavens. Such observations and records have left a rich astronomical legacy.

In ancient China, it was believed that events in the sky directly reflected events on earth. If, for example, a comet suddenly appeared in the sky it was thought that something important and unexpected was about to happen on earth, perhaps something like a major battle. The emperor was believed to be the Son of Heaven who had been given the Mandate, or right to rule, by Heaven itself. It was vital that he could prove that he retained this right by predicting the movements of the sky accurately. His astronomers were therefore expected to watch the sky very carefully and they kept accurate records of the movements of the stars and planets, recording events such as Halley’s comet and various eclipses of the sun and moon.

Ancient Chinese astronomers diligently observed solar eclipses, and made scrupulous records, maintaining continuity of the recording. For instance, the record 37 solar eclipses during a period of 294 years -- from 770 to 476 BC. Studies have proved that most of these records are reliable. Later, recordings of solar eclipses begun in the 3rd century BC and of lunar eclipses begun in the 5th century BC continued all the way to contemporary times.

While Western astronomers of the Renaissance period were still arguing in 1615 who was the first to discover sunspots, Chinese astronomers had already accumulated a large amount of records on sunspots. Now it is known that the earliest records of sunspots were made in 28 BC by Chinese astronomers during the reign of Emperor Cheng of the Western Han Dynasty. From then until the late Ming Dynasty in the mid-17th century, Chinese history books recorded more than 100 sunspots. Furthermore, they also took note of other phenomena concerning the sun, such as solar prominences and coronas. The first record of a solar prominence has been found in a tortoise shell inscription, which describes "three suddenly bursting fires eating a chunk of the sun". According to statistics, sunspots occur in a cycle every 11.33 years on average, which is in conformity with ancient Chinese documents and once again testifies to the fact that records of sunspots made by ancient Chinese people are a very valuable astronomical legacy.
