15.1. Focusing on Computer Science

At this point, you probably have a lot of questions about what you've been doing in this book.

• "Why is Photoshop so much faster on large pictures than the programs I'm writing in Java?"

• "How fast can we get our programs to go?"

• "Does it always take this long to write programs? Can you write smaller programs to do the same things? Can you write programs more easily than this?"

• "What does programming look like in other programming languages?"

The answers to most of these questions are known or studied in computer science. This part of the book is an introduction to some of those topics as a signpost to get you started in exploring computer science further.
