Events Occured in Scienctist Life

1088

In his Dream Pool Essays or Dream Torrent Essays (夢溪筆談; Mengxi Bitan) of 1088, Shen was the first to describe the magnetic needle compass, which would be used for navigation (first described in Europe by Alexander Neckam in 1187).

2000

Shen implemented an improved version of the camera, nearly 2000 years later.

1321

His description of an ancient crossbow mechanism which he himself unearthed proved to be a Jacob's staff, a surveying tool which wasn't known in Europe until described by Levi ben Gerson in 1321.

1031

Shen Kuo was born in Qiantang (modern-day Hangzhou) in the year 1031.

1051

Shen Zhou died in the late winter of 1051 (or early 1052), when his son Shen Kuo was 21 years old.

1054

Shen Kuo grieved for his father, and following Confucian ethics, remained inactive in a state of mourning for three years until 1054 (or early 1055).

1054

As of 1054, Shen began serving in minor local governmental posts.

1072

By 1072, Shen was appointed as the head official of the Bureau of Astronomy.

1073

While Shen was appointed as the regional inspector of Zhejiang in 1073, the Emperor requested that Shen pay a visit to the famous poet Su Shi (1037–1101), then an administrator in Hangzhou.

1072

In 1072, Shen was sent to supervise Wang's program of surveying the building of silt deposits in the Bian Canal outside the capital city.

1075

He gained further reputation at court once he was dispatched as an envoy to the Khitan Liao Dynasty in the summer of 1075.

1081

During the autumn months of 1081, Shen was successful in defending Song Dynasty territory while capturing several fortified towns of the Western Xia.

1070

In the 1070s, Shen had purchased a lavish garden estate on the outskirts of modern-day Zhenjiang, Jiangsu province, a place of great beauty which he named "Dream Brook" ("Mengxi") after he visited it for the first time in 1086.

1088

Shen Kuo permanently moved to the Dream Brook Estate in 1088, and in that same year he completed his life's written work of the Dream Pool Essays, naming the book after his garden-estate property.

1095

It was there that Shen Kuo spent the last several years of his life in leisure, isolation, and illness, until his death in 1095.

1045

Following Shen's reasoning and correcting the findings of the dissection of executed bandits in 1045, an early 12th-century Chinese account of a bodily dissection finally supported Shen's belief in two throat valves, not three.

2000

Mozi first described the concept of camera obscura 2000 years earlier during the Warring States period.

1119

The book of the author Zhu Yu, the Pingzhou Table Talks published in 1119 (written from 1111 to 1117), was the first record of use of a compass for seafaring navigation.

1288

Needham asserts Shen had discovered the survey device known as Jacob's staff, which was not described elsewhere until the Provençal Jewish mathematician Levi ben Gerson (1288–1344) wrote of it in 1321.

1074

While visiting the Taihang Mountains in 1074, Shen Kuo noticed strata of bivalve shells and ovoid rocks in a horizontal-running span through a cliff like a large belt.

1080

Around the year 1080, Shen Kuo noted that a landslide on the bank of a large river near Yanzhou (modern Yan'an) had revealed an open space several dozens of feet under the ground once the bank collapsed.

1546

Shen's description of soil erosion and weathering predated that of Georgius Agricola in his book of 1546, De veteribus et novis metallis.

1802

Furthermore, Shen's theory of sedimentary deposition predated that of James Hutton, who published his groundbreaking work in 1802 (considered the foundation of modern geology).

1297

Wang Zhen also improved its use by inventing wooden movable type in the years 1297 or 1298, while he was a magistrate of Jingde, Anhui province.

1439

This included the printing works of Hua Sui (1439–1513), who pioneered the first Chinese bronze-type movable printing in the year 1490.

1718

In 1718, during the mid Qing Dynasty (1644–1912), the scholar of Tai'an known as Xu Zhiding developed movable type with enamelware instead of earthenware.

1784

There was also Zhai Jinsheng (b. 1784), a teacher of Jingxian, Anhui, who spent thirty years making a font of earthenware movable type, and by 1844 he had over 100,000 Chinese writing characters in five sizes.

1956

In modern times, the best attempt at a complete list and summary of Shen's writing was an appendix written by Hu Daojing in his standard edition of Brush Talks, written in 1956.

1126

Around the year 1126 it was combined with a similar collection by the famous Su Shi (1037–1101), who was ironically a political opponent to Shen Kuo's faction of Reformers and New Policies supporters at court, yet it was known that Shen Kuo and Su Shi were nonetheless friends and associates.

1983

His tomb was eventually destroyed, yet Ming Dynasty records indicated its location, which was found in 1983 and protected by the government in 1986.

2001

The Hangzhou Municipal Committee completed a restoration of Shen's tomb in September 2001.

1985

In addition to his tomb, Shen Kuo's Mengxi garden estate, his former two-acre (8,000 m²) property in Zhenjiang, was restored by the government in 1985.

1964

The Purple Mountain Observatory in Nanjing discovered a new asteroid in 1964 and named it after Shen Kuo (2027 Shen Guo).
