" Engineers ... are not superhuman. They make mistakes in their assumptions, in their calculations, in their conclusions. That they make mistakes is forgivable; that they catch them is imperative. Thus it is the essence of modern engineering not only to be able to check one's own work but also to have one's work checked and to be able to check the work of others. "
~ Henry Petroski

     From the study of past engineering failures, it can only educate and remind us that it is of utmost importance that engineers uphold the professional ethics and standards bestow upon them. All the decisions made by an engineer should be done ethically and carefully. Through great power comes great responsibility.  The  disasters that occured is a reflection of mistakes that should not and cannot be done again. As an engineering student, I hope that this class can show me what it means to be an engineer. And also build upon past failures to create better structures or tools that can help the advancement of technology.
