Throughout my life, I have acquired knowledge in many different ways. Although formal education has played an important role, I would not say that it has provided the bulk of what I know today. Instead, my knowledge has developed through a combination of listening to others, reading, observation, experience, curiosity, and a willingness to continually challenge myself.
One of the most important ways I have acquired knowledge is by listening to others, particularly my students. As a teacher, I have discovered that students can be an extraordinary source of learning. The questions they ask often force me to think more deeply about a subject. Sometimes a seemingly simple question exposes a gap in my own understanding and motivates me to investigate further. In this way, teaching has become a two-way learning process: while I am teaching my students, they are continually teaching me as well. Their curiosity has often encouraged me to develop a much more thorough understanding of the subjects I teach.
My childhood also played an important role in developing my approach to learning. I was sick quite frequently as a child and, as a result, spent a considerable amount of time by myself. Much of this time was spent reading and learning. Fortunately, I had supportive parents who encouraged my curiosity and provided me with opportunities to explore subjects that interested me. Being comfortable with my own company also gave me the opportunity to develop the habit of learning independently.
Another important method has been rising to the challenge. I particularly enjoy teaching new courses because they force me to broaden my horizons and increase my knowledge base. When I am faced with a subject that I do not know well, I see it less as an obstacle and more as an opportunity. Preparing to teach something new requires me to research, organize, question, and ultimately develop enough understanding to explain the material to someone else. This process has continually pushed me beyond what I already know.
Reading has probably been one of the most consistent features of my lifelong learning. As a child, I read publications such as Look and Learn and World of Knowledge. As I grew older, my interests expanded to magazines such as New Scientist, The Economist, BBC History Magazine, National Geographic, Time, World Football, Military History, Scientific American, and Omni. These publications exposed me to an enormous range of subjects and helped develop a broad rather than narrowly focused knowledge base.
I have also learned a great deal through documentaries. Television documentaries introduced me to subjects that I might not otherwise have encountered, and more recently, YouTube has become an incredibly useful source of information. The ability to watch lectures, interviews, demonstrations, historical programs, and documentaries on virtually any subject has made learning more accessible than ever before.
Reference books have been another important source of knowledge. I spent considerable time with resources such as the Guinness Book of Records, World Almanac, Pears Encyclopedia, the Chronicle series, and World Book when I was younger. These books encouraged me to explore facts simply because they were interesting. Often, one piece of information would lead to another, creating a chain of curiosity that took me into completely different areas of knowledge.
More generally, I have always enjoyed reading books. Even now, I will normally have three or four books on the go at any given time. I tend to read across different subjects rather than concentrating exclusively on one area. This allows me to make connections between seemingly unrelated ideas and continually expand my understanding of the world.
The Internet has transformed this process of learning. It is remarkable how much knowledge is now available at our fingertips. The real skill, however, is knowing where to find reliable information and being able to distinguish useful sources from unreliable ones. The Internet has allowed me to investigate questions almost immediately, follow my curiosity, and explore subjects far beyond the limitations of a traditional library.
I have also used quiz books as a way of acquiring and reinforcing knowledge. Series such as Isaac Asimov's Super Quiz books, as well as the British Mastermind series, were particularly valuable. Quizzes encouraged me not only to discover new information but also to test what I actually remembered. There is something particularly satisfying about realizing that information encountered years earlier has remained part of my knowledge base.
Formal schooling and university education have obviously contributed to my knowledge. Completing two science degrees as well as a degree in education provided me with important foundations, taught me how to approach problems systematically, and developed my ability to research and evaluate information. However, I would not consider formal education to be the primary source of my overall knowledge. Rather, it gave me the tools and foundations that allowed me to continue learning independently.
Finally, and perhaps most importantly, I have learned through experience. Experience truly is one of the greatest teachers. My careers in engineering and teaching have provided countless opportunities to learn by doing, making mistakes, solving problems, and interacting with others. However, I have come to believe that experience by itself is not enough. The real learning occurs when we take the time to reflect meaningfully on that experience. Asking what happened, why it happened, what could have been done differently, and what can be learned from it transforms an experience into knowledge.
Looking back, I realize that my approach to acquiring knowledge has never been dependent on a single method. It has been an ongoing process involving curiosity, reading, listening, questioning, teaching, formal education, technology, and experience. Perhaps the most important characteristic underlying all of these methods is a willingness to remain curious. I have never viewed learning as something that ends with graduation or the completion of a degree. Instead, I see it as a lifelong process in which every question, book, student, experience, and new challenge provides another opportunity to learn.
