Mind The Gap: The Labyrinthine Story Of Planetary Orbits, Mathematics, And The Titius-bode Rule
This book is concerned with two tightly knit topics — those of mathematics and astronomy. Its focus is primarily concerned with planetary astronomy, and specifically the history of accounting for the spacing of planetary orbits. The story begins with the ancient Greek philosophers and continues to the modern era and the new data being gleaned from the study of exoplanetary systems. Throughout the text, the manner in which mathematical theory has been used to decipher, and impose order upon the solar system, will be examined. Attention and discussion will be directed towards the so-called Titius-Bode rule, a long-standing ordering principle, that in fact it has no physical underpinning or explanation.The story presented will look at how humanity has learned about the workings of the solar system, and it will look at the philosophical problems that arise when mathematical exposition leads observation. Furthermore, the fundamental role of mathematics in the development of physical theory is examined, and it is argued that there are some gaps in our knowledge of the solar system (and the universe) that mathematics and physical theory will never successfully bridge. The text will present material at the informed-amateur scientist, university undergraduate student level.
On Both Sides of the Strait of Gibraltar
In On Both Sides of the Strait of Gibraltar Julio Samsó studies the history of medieval astronomy in al-Andalus (Muslim Spain), the Maghrib and the Christian kingdoms of the Iberian Peninsula. He proves that the Arabic, Latin, Hebrew, Castilian and Catalan sources belong to the same tradition whose origin can be dated in the 11th century due to the changes in Ptolemy’s astronomical theory introduced by the Toledan astronomer Ibn al-Zarqālluh/Azarquiel. The book also analyses the role of al-Andalus and the Iberian Peninsula in the transmission of Islamic astronomy to Europe and justifies the fact that Eastern Islamic works published after ca. 950 CE were not accessible to medieval European scholars because they had not reached al-Andalus.
