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 ...

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 ...

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 ...

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 ...

The needle will turn and then come to a complete stop. It will be facing magnetic north. You can check this by placing the compass next to the bowl. The needle is being affected by the Earth’s ...
