How does the Sextant symbolize the person who worked on the famed Hevelius star catalog and star atlas throughout its production, from observation to publication?
Elisabeth Hevelius, wife of Johann Hevelius, was an astronomer in her own right. They worked together in the observatory of their Gdansk home to measure angular widths and distances with a great sextant, which required two observers at a time. The Sextant was among the new constellations they proposed in Uranographia (1690), the most detailed and influential celestial atlas of the 17th century. The Uranographia contains 54 beautiful double page engraved plates of 73 constellations, and 2 oversized folding plates of planispheres.
In order to understand the history of a book, it is important to understand the structure and organization of a book - it's anatomy. This learning leaflet explains the basic parts of a book through some simple exercises.

For the Galileo’s World exhibition, Jonathan A. Annis, a graduate student in the OU School of Music, worked as co-curator of the Music of the Spheres gallery. In this role he composed a suite for harp, flute (doubling alto flute) and oboe (doubling English horn) entirely comprised of musical themes from Kepler’s Harmonices mundi. Annis arranged the themes, but they derive from Kepler’s musical description of the harmonic law. In this piece, Kepler’s universe becomes a cosmic dance. Visitors to the Music of the Spheres gallery during the Galileo's World exhibition were able to listen to a short excerpt of the suite on an iPad kiosk. (Background. Learning Leaflet.) CC-by-sa-nc.
Is there a mathematical basis of the universe?
Johann Kepler's "Mystery of the Universe" is one of the brilliant illustrations in the history of astronomy. Kepler used the five regular Pythagorean solids to refute the major objections to Copernicanism. In this work he demonstrated that vast empty regions lying between the planetary spheres, which were required by Copernicus, were not wasted space. Rather, these gaps perfectly matched, within the limits of observational error, the geometry of the 5 regular Pythagorean solids.
Johann Bode, director of the Observatory of the Berlin Academy of Sciences, produced the last of the four major celestial atlases in which artful depictions of constellation figures appear alongside the most up-to-date scientific data. 20 large copperplate engravings plot more than 17,000 stars, far more than any previous atlas. Bode included new stars for the southern hemisphere, along with constellations recently invented by Hevelius and Lacaille. Bode depicted more than 100 constellations, compared with 88 officially recognized today. Some which appeared in this atlas for the first time, but are not officially recognized today, include the Cat, the Printing Press, the Montgolfier Balloon, and the Electric Generator.
This coloring book, produced by the OU Academy of the Lynx, was made from images in Bode's book.
Identify six common constellations by their star patterns.
Urania's Mirror was a set of 32 constellation cards designed to aid in identifying the constellations by distinguishing between star patterns and constellation figures. This set includes six constellations, selected so that at least one of them is visible (in the northern hemisphere) at any time of the year. Holes punched in the positions of bright stars allow one to hold any card up to a light and compare the star pattern with the constellation figure.

How did knowledge spread in Galileo’s world?
Johann Schreck joined the Jesuit order in 1611, the same year that he used Galileo's telescope to observe the satellites of Jupiter. Upon becoming a Jesuit, Schreck joined the Jesuit mission in China, taking with him a scientific library of approximately 7,000 volumes as well as a Galilean telescope. Schreck's story is the beginning of a century-long exchange of scientific ideas between Europe and Asia.
What are your favorite constellations?
This beautiful star atlas fused artistic beauty and scientific precision, the last of the four major star atlases in which artful depictions of constellation figures appear alongside the most up to date scientific information. Bode was director of the Observatory of the Berlin Academy of Sciences.
William Schickard, a friend of Kepler’s, designed this “astroscopium,” a model intermediate between a planisphere and a celestial globe, to calculate the positions of the stars for any day and hour of the year. Use this learning leaflet to construct your own astroscopium.

Are they talking about physics as they stroll through the garden?
At a time when very few scientists were capable even of reading Newton's masterwork of physics, the "Mathematical Principles of Natural Philosophy," Madame du Châtelet mastered it and translated it into French. She also defended Newton in the Newton-Leibniz controversy.
