Discover Physics

Since birth, you've wanted to discover things. You started out by putting every available object in your mouth. Later you began asking the grownups all those 'why' questions. None of this makes you unique - humans are naturally curious animals. What's unusual is that you've decided to take a physics course. There are easier ways to satisfy a science requirement, so evidently, you're one of those uncommon people who has retained the habit of curiosity into adulthood, and you're willing to tackle a subject that requires sustained intellectual effort.
