The “modern” education system. It hasn't changed much since it started back in 1837. The same rules apply. You come into class, pick a seat, and watch an adult teach you the basics. The rest is left to the child. Whether they pay attention or not, it's up to them. The problem here is, even if the child tries to pay attention, many find it difficult to learn this way.

A stingy ex-husband, a teenage daughter, and a rusted-out Ford Escort have multiplied her troubles. Tripping over a dead body while on her morning jog seems like another incident for the minus column. But then her new editor at the newspaper gives her a regular column detailing the investigation. He's handsome, single, and just a bit mysterious. Suddenly, Colleen's life is on the plus side. Unfortunately, one dead algebra teacher plus two secret affairs plus four suspicious suspects quickly adds up to three perilous "accidents" for Colleen.

From Leonardo Da Vinci to John Dee and Comenius, from George Eliot to Oliver Sacks and Susan Sontag, polymaths have moved the frontiers of knowledge in countless ways. But history can be unkind to scholars with such encyclopaedic interests. All too often these individuals are remembered for just one part of their valuable achievements. In this engaging, erudite account, renowned cultural historian Peter Burke argues for a more rounded view.

For thousands of years mathematicians solved progressively more difficult algebraic equations, until they encountered the quintic equation, which resisted solution for three centuries. Working independently, two prodigies ultimately proved that the quintic cannot be solved by a simple formula. The first popular account of the mathematics of symmetry and order, The Equation That Couldn't Be Solved is told not through abstract formulas but in a beautifully written and dramatic account of the lives and work of some of the greatest and most intriguing mathematicians in history.

Go on an adventure with Polly as she learns how to use special names to categorize shapes! Any closed, flat shape with at least three straight sides is called a polygon. Did you know a quadrilateral—or a shape with four straight sides—can have several names? You can call one a parallelogram, a rhombus, a trapezoid, or even a square! What shapes can you recognize?

Join us as we go on a journey into the world of symmetry! Learn about the wonders of line symmetry—or reflection—as you create mirror images and watch how rotational symmetry works in this brief peek into this area of geometry.

Math is not only the game of numbers but also the language of nature. As a matter of fact, it has been established through research that the more we understand our universe, the more we discover interesting mathematical connections. For instance, flowers have spirals that are carefully lined up in a special sequence of numbers commonly referred to as Fibonacci numbers. This sequence can be studied, understood, and generated.
