Most of us see physics as a quest for understanding the physical world around us. While this may be well true, we sometimes mistakenly take this reasonable observation to a naïve conclusion. We assume that, at some time in the not-so-distant future, all will be known. This is not just true today. Near the end of the 19th century, after Maxwell’s equations had been published, many scientists assumed that most of the truths about the physical world had been discovered and revealed. All that remained was to fill in some pieces here and there.

Now more than 100 years later, we can look back and see how naïve this idea was. Today, in the early part of the 21st century, the best theories that we have leave us with more questions than answers. When one begins to develop an appreciation for all of this, one is compelled to conclude that the universe in which we live is far more complex than we could ever imagine.

In your study of physics, you have seen theories proposed, tested, and refined or abandoned. Throughout this untiring process of testing and re-testing, one thing has remained constant: that learning happens when we ask questions. Perhaps this is the greatest lesson of all: that science, and indeed life, is about developing a sense of wonder, cultivating a thirst for understanding and a true humility to ask questions.

With the above thoughts, we truly conclude our Physics 12. I thank all of you for being part of this exciting journey of learning.
