September 11, 2001 will forever be remembered inpodern history as day of infamy. Four planes were commandeered by terrorists to crash into the two towers of the World Trade Center in New York City, the Pentagon, and the White House or the Capitol. Three of the planes hit their targets, while the fourth plane crashed on a field in rural Pennsylvania and missed its target because of the initiative and joint action of the passengers and crew of the plane. Naturally, questions crop up in the aftermath. Who is the group behind the attack and what kind of influence do they hold over the individuals who carried out the attack? Why target the United States and ordinary civilians? What could have been done to thwart or even prevent it? Such questions may be answered by the different disciplines under the social sciences, which look into the historical, cultural, sociological, psychological, and the political forces that shape the actions of individuals and its impact on society. Simply put, social science is the study of society. It is a useful instrument in understanding the complexities and issues involved in the interrelationships of the different variables that produce the state of affairs at every level in society.
