Al-Biruni is regarded as one of the greatest scholars of 11th century and was well versed in physics, mathematics, astronomy, and natural sciences, and also distinguished himself as a historian, chronologist and linguist.[1]

Of the 146 books known to have been written by Bīrūnī, 95 were devoted to astronomy, mathematics, and related subjects like mathematical geography.[2]

  • The Mas'udi Canon (Persian قانون مسعودي) - an extensive encyclopedia on astronomy, geography, and engineering, named after Mas'ud, son of Mahmud of Ghazni, to whom he dedicated.
  • Leif Ericsson claims to have made landfall at three lands in North America, one of which he names Vinland meaning the land of wine.[3]

Warfare

[edit]
  • A Chinese manual on warfare includes the earliest known description of gunpowder.[4]

Printing

  • The concept of movable kind for printing is pioneered in China, using fired clay, but it proves impractical.[5]

Astronomy

[edit]
  • The Book of Instruction in the Elements of the Art of Astrology (Kitab al-tafhim li-awa’il sina‘at al-tanjim[6]).
  • The Remaining Signs of Past Centuries (Arabic الآثار الباقية عن القرون الخالية) - a comparative study of calendars of different cultures and civilizations, interlaced with mathematical, astronomical, and historical information.
  • The Mas'udi Canon (Persian قانون مسعودي) - an extensive encyclopedia on astronomy, geography, and engineering, named after Mas'ud, son - a question and answer style book about mathematics and astronomy, in Arabic and Persian.
  • Astronomers in China and Japan observe the explosion of the supernova which is still visible as the Crab Nebula.[7]

Medicines

[edit]
  • Pharmacy - about drugs and medicines.

Surgery

[edit]

Geology and minerals

[edit]
  • Gems (Arabic الجماهر في معرفة الجواهر) about geology, minerals, and gems, dedicated to Mawdud son of Mas'ud.

[edit]
  • Su Sung, a Buddhist monk, created in China the principle of the escapement in his tower clock worked by a water wheel.[9]

Births

[edit]

Record keeping was not great at the time, so it is unknown how much people were born around that time.

Deaths

[edit]

Record keeping was not great at the time, thus the deaths of significant figures in science in the 11th century are primarily unknown.
