Ok, today was the first day of school. I've read the first chapter of one of the books, our assignment over the weekend for this class. This is found on the first page of the textbook. Mind you, this is a COLLEGE textbook, on the science behind radiography....

In the vast and beautiful expanse of the Arctic region, there was once a great, isolated iceberg floating in the serene sea. Because of its location and accessibility, the great iceberg became a Mecca for penguins from the entire area. As more and more penguins flocked to their new home and began to cover the slopes of the ice field, the iceberg began to sink further and further into the sea. Penguins kept climbing on, forcing others that once were securely ensconced off the island and back into the ocean. Soon, the entire iceberg became submerged owing to the sheer number of penguins that attempted to take up residence there.

Moral: The PENGUIN represents an important fact or bit of information that we must learn to understand a subject. The brain, like the iceberg, can retain only so much information before it becomes overloaded. When this happens, concepts begin to become dislodged like penguins from the sinking iceberg. So, the key to learning is to reserve space for true "penguins" to fill the valuable and limited confines of our brains. Thus, key points in this book are highlighted and referred to as "PENGUINS."
