FIREWORKS: PYROTECHNIC ARTS AND SCIENCES IN EUROPEAN HISTORY
Simon Werrett | University College London
Fireworks are synonymous with celebration in the twenty-first century. But pyrotechnics—in the form of rockets, crackers, wheels, and bombs—have exploded in sparks and noise to delight audiences in Europe ever since the Renaissance. Here, Simon Werrett shows that, far from being only a means of entertainment, fireworks helped foster advances in natural philosophy, chemistry, mathematics, and many other branches of the sciences.
Fireworks brings to vibrant life the many artful practices of pyrotechnicians, as well as the elegant compositions of the architects, poets, painters, and musicians they inspired. At the same time, it uncovers the dynamic relationships that developed between the many artists and scientists who produced pyrotechnics. In so doing, the book demonstrates the critical role that pyrotechnics played in the development of physics, astronomy, chemistry and physiology, meteorology, and electrical science. Richly illustrated and drawing on a wide range of new sources, Fireworks takes readers back to a world where pyrotechnics were both divine and magical and reveals for the first time their vital contribution to the modernization of European ideas.

Boston College Consolidated Financial Statement: $6.509B
Boston College is a private Jesuit research university in Chestnut Hill, Massachusetts. Gasson Hall is a symbol of Boston College, representing the university’s commitment to academic excellence, spiritual values, and the pursuit of knowledge. It The hall continues to serve as an important part of the Boston College campus, housing administrative offices, classrooms, and the university’s Honors Program.
In “The Social Network,” Gasson Hall was used as a filming location for several scenes that take place at Harvard University, which is where Mark Zuckerberg attended college before he created Facebook. Specifically, Gasson Hall was used as a stand-in for Harvard’s Memorial Hall, which is a large Gothic Revival building that houses a dining hall and a chapel.
The scene in “The Social Network” that was filmed in Gasson Hall shows Mark Zuckerberg (played by Jesse Eisenberg) and Eduardo Saverin (played by Andrew Garfield) attending a disciplinary hearing in front of the Harvard administration. The hearing takes place in a large ornate room with stained glass windows and a high vaulted ceiling, which is actually the Reading Room on the third floor of Gasson Hall. The filmmakers made some minor changes to the room, such as adding a portrait of John Harvard and replacing some of the furniture, but overall, the space is very recognizable as Gasson Hall.
