Fireworks and the Fourth of July

What would the Fourth of July be without fireworks? It's only fitting that we celebrate Independence Day with fireworks, because fireworks are fueled by gunpowder, which has played a key role in encouraging the development of modern democracies. Indeed, the World History Encyclopedia asserts that "Gunpowder may be the most important discovery in world history" (Watts 668).

How can this be? In the Middle Ages, just a few armored knights on horses could defeat a large number of foot soldiers. Since a few could physically overpower many, the same few could exercise political power over many.

But this began to change during the Hundred Years War, in which English archers defeated French knights in several key battles, including the spectacular rout at Agincourt in 1415. Gunpowder hadn't yet played a specific role in these battles, but the defeats illustrated that commoners, such as English longbowmen, could defeat hitherto more powerful noblemen, such as mounted French knights, in battle (Agincourt).

Soon, gunpowder weapons made it even easier to level the playing field in battle, requiring less physical strength and training than longbows yet capable of piercing thicker armor (G. Phillips 580, 584, 589). This shift in military power helped lead to a shift in political power: If a ruler relied heavily on common soldiers, then these commoners could demand a greater say in things. As Isaac Asimov explains, "In time gunpowder helped destroy the medieval order of society by giving armies a means to level castle walls, and the man on foot a chance to shoot down a horseman in armor" (25).

Speaking of castle walls, gunpowder allowed the Ottomans to breach the mighty walls of Constantinople in 1453 using massive cannons (Islam). The Ottoman takeover of Constantinople impaired overland trade between East and West, spurring exploration for alternative routes--which in turn led to Christopher Columbus's discovery of the New World (W. Phillips, Jr, and C. Phillips 47, 49-51).

Americans' independent spirit stems partially from the ready availability of land in this new world. With an open frontier, colonists dissatisfied with the settlement in which they lived could often push into the frontier and start their own settlement--not an option in crowded Europe. The independent mindset held by many American colonists contributed to the eventual revolt against Great Britain, heralded by the adoption of the Declaration of Independence on July 4, 1776 (Turner 30, 78-79).

So, as we enjoy spectacular Fourth of July fireworks displays, their smoke and loud explosions can remind us all the more of the origins of our nation's independence and democracy! The libraries at Austin Community College have abundant resources for exploring the many facets of a subject such as gunpowder. One could, for example, investigate its Chinese origins, its chemistry, its use in fireworks and mining, or its role in encouraging the development of industrial fertilizer production, and with it, the ability to feed an ever growing world population (Smil xv, 46-48). Here are a few such resources:

*New* Finding Scientific Information Tutorial

 Austin Community College Library Services is pleased to announce a new addition to the Research Success Tutorials Suite:

Finding Scientific Information

This tutorial includes a quiz at the end to test student’s knowledge for:

1. How scientific information is published
2. How to access relevant scientific databases
3. How to search science databases effectively
4. How to find original research
The quiz results may be printed, emailed or uploaded as a document in Blackboard. The tutorial is available 24/7 from the ACC Library web site and makes an excellent introductory assignment for any science writing assignment as well as a discussion topic starter for any science lecture. This tutorial may also be assigned before a librarian-led research instruction class, such as a CHEM lab librarian session.
Students who are assigned to write a paper or research information in any of the science courses or programs will find helpful information - just in time to complete their assignments. The interactive and engaging tutorial is designed to give students the information they need to understand how to research in any area of the sciences including nursing, environmental science, veterinary technology and biology.
We are working on more tutorials to help your students be successful in any research assignment. Stay tuned for more updates!
