What are your favorite constellations?
Urania's Mirror was a set of constellation cards designed to aid in the teaching and learning of constellations. This set includes 32 cards, each focused upon one or a few constellations. 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.

Why did people come to Hildegard’s convent?
Hildegard of Bingen, Abbess of convents at Rupertsberg and Elbingen in the 12th century, explained their herbal remedies and medical procedures in her book Physica. In addition to this work on medicine, Hildegard wrote other works on cosmology and theology, corresponded in nearly 400 letters with abbots, popes and emperors, and created at least 70 musical compositions. This OER explores the significance of Hildegard of Bingen.
How important in science is usability?
Prior to Newton, perhaps half a dozen astronomers accepted Kepler s three laws. Galileo was typical in ignoring Kepler s accomplishments. Yet this beautiful book is an exception. Maria Cunitz was not only one of the first astronomers to adopt Johann Kepler's astronomy, but because of the usability of her tables, she made the accuracy of Kepler's laws easy to grasp.
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.
Included in this learning leaflet are three parts:
(1) Introduction - DOWNLOAD
(2) Activity - DOWNLOAD
(3) Handout - DOWNLOAD
What is the difference between a calculating machine and a computer?
In notes appended to Ada Lovelace's translation of one of the first introductions to Charles Babbage's "Analytical Engine," she included an in-depth analysis of the significance and potential of Babbage's machine design. These dense notes, much longer than the text she translated, explained how Babbage's machine had the potential of becoming a programmable computer, instead of merely a calculator.
It is often thought that Galileo's discovery of the phases of venus demonstrated the contested heliocentric model of the universe. However, such an understanding is overly simplistic of the early modern account of astronomy. Use this learning leaflet to learn more.
How do art and travel benefit natural history?
Maria Merian (1647-1717), skilled in both art and natural history, studied the relationships between flowers and insects. She conducted field expeditions around the world, carried out research in gardens and museums, and produced detailed sketches and beautiful paintings, and even bred insects to aid in her entomological investigations.
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.
Where will the quest of discovery lead you?
Science is a quest of discovery, the challenge of boldly exploring where no one has gone before. That is the appeal and rhetorically durable theme which has made this woodcut so appealing.
Many have reprinted this illustration through the years, sometimes without knowing its original source. It first appeared in this popular work on meteorology. Flammarion was an astronomer and popular science writer who worked at the Juvissy Observatory in Paris. He was mistaken in his belief that scientists, writers and theologians in the Middle Ages and Renaissance regarded the Earth as flat.
