'The Secrets of Life: Scientists, Mathematicians, and the Hunt for Answers' examines some of the ground-breaking work in medical sciences, astronomy, and mathematics that has led to our current understanding of what life is and how to maintain it. While the exhibition features treasured texts such as first editions of Galileo's Siderus Nuncius (with the first published observations of the heavens through a telescope) and of Darwin's On the Origin of Species, it also exhibits never-before-seen material from former students and academic staff on pioneering work in fighting disease and in processing DNA, increasing our comprehension of the building blocks of life. The exhibition is open to the public Tuesdays and Thursdays, 2:00-4:00pm, and at other times by appointment (please email: library@christs.cam.ac.uk).
