If all the compasses in the world started pointing south rather than north, many people might think something very strange, very unusual, and possibly very dangerous was going on. Doomsayers would ...

Dividers and compasses are drawing instruments that have been used since antiquity to measure distances, transfer lengths from one drawing to another, and draw circles. The Greek mathematician, Euclid ...

Atoms as Tiny Compasses A research team at CU Boulder, led by physicists Cindy Regal and Svenja Knappe, has taken a major step forward in solving these challenges. Their work, published in Optica ...

Magnetotactic bacteria synthesize magnetic iron nanominerals, which function as tiny compasses that allow the microbes to navigate using Earth's geomagnetic field. Earth's iron cycle is a very ...

In geometry a construction is an accurate drawing. There are two main constructions which can be done using a ruler, a pair of compasses and a pencil. Place the compasses on the left-hand endpoint ...
