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 ...

On Earth, compasses always point north—but when you’re drifting outside our planet’s magnetosphere, things get more complicated.

Compasses are navigational instruments that determine direction relative to Earth’s magnetic poles. Mechanical versions of these magnetically-sensitive devices usually contain a face with the cardinal ...

On Earth, the magnetic field of our planet points a compass north, but in space, things are a bit more complicated.

Dalston's got no shortage of cool but manufactured places to hang out. The Three Compasses manages to feel trendy even though its interior hasn't changed much in decades. That's the charm of the ...

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 ...

For example, combination compasses and magnetometers are used on satellites and aboard airplanes that map the local structure of the Earth's magnetic field. Navies use compasses and magnetometers to ...
