Here's a project where you can try your hand at being a detective with your computer. In this project you'll write a program to do some basic analysis of features of written text (for example, counting the length of each word in the text, or the number of words in each sentence). Then you'll see if you can use the information from your text analysis program to find measurements that can distinguish one author from another. After analyzing known samples of several authors' writings, can your… Read more

Imagine yourself as a software engineer, a decade and a half from now. You are called upon to help solve the world energy crisis by programming nano-organisms (NANORGs) to extract energy from industrial sludge. Your program must be small enough to fit in the NANORGs' tiny processors, yet at the same time meet several challenges. First and foremost, your NANORGs need to navigate on their own, extract energy from the sludge, and find collection points to deliver the harvested energy. Second,… Read more

Can you remember all of your ABC's? Computers need to "remember" letters too. Every time we use a computer to write a story, the computer needs to "remember" the letters in the story by saving them to the computer's memory as a file. In this experiment find out how much memory it takes for the computer to "remember" a series of letters. Read more

thumbnail This is a straightforward project that shows you how data can be digitized and stored on magnetic recording media. You'll learn how alpha-numeric characters are digitized, and you'll use bar magnets to represent the individual data "bits." You'll also learn about how much information can be stored in a small space (recording density), and how magnetic data can be erased. Read more
