Are you interested in boomerangs? In this issue we explain how to make your own boomerang at look at some of the physics that make boomerangs work. Is a boomerang really a kind of gyroscope? And what are gyroscopes? Besides, we look at the history of mathematical proof.
Issue 7
Starting in this issue, PASS Maths is pleased to present a series of articles about proof and logical reasoning. In this article we give a brief introduction to deductive reasoning and take a look at one of the earliest known examples of mathematical proof.

If boomerangs are really gyroscopes, then what are gyroscopes? In this article, we explore some more of the physics of gyroscopes, and demonstrate some interesting experiments you can do with them.

Whatever is so wonderful about point B that makes all the people at point A want to get there? Robert Hunt sits at point C, and muses on the problem.

In this article, we look at the physics behind the curved flight path of a returning boomerang, and explain that boomerangs are really a kind of gyroscope. We even show you how to bang up a boomerang yourself!

Here's how you can make your own crossshaped boomerang  and it's safe enough to fly indoors! Hugh rolls up his sleeves and proves that theory isn't everything.

Bisecting a given angle using only a pair of compasses and a straight edge is easy. But trisecting it  dividing it into three equal angles  is in most cases impossible. Why?
