Orienting means finding the cardinal directions. First, hold the compass flat, parallel to the ground at about belly-button ...

In the days since GPS was invented, many of us have lost the skill of navigating by a good old compass and map. As a family ...

New Atomic-Laser Compass Determines Direction of Magnetic Fields Optically. By ... Researchers at Harvard wanted a compass not only sensitive to the size of a magnetic field, but also its direction.

With a compass, you can find out which way a magnetic pole is—and from that, you can approximate other directions such as where south, east and west are as well. On supporting science journalism ...

Monarch butterflies have a keen sense of direction, even on cloudy days. This is because they have a magnetic compass to direct their migration in addition to navigating by the position of the sun ...

Every year, billions of birds migrate in and out of the United States. And across the world, birds fly thousands of miles to reach their seasonal destinations. Some birds, like the Arctic tern ( ...

Polarized light modulates light-dependent magnetic compass orientation in birds. Proceedings of the National Academy of Sciences , 2016; 201513391 DOI: 10.1073/pnas.1513391113 Cite This Page : ...

The magnetic compass that birds use for orientation is affected by polarized light. This previously unknown phenomenon was discovered by researchers at Lund University in Sweden.

Some inventions are so simple that it’s hard to improve them. The magnetic compass is a great example — a magnetized needle, a bit of cork, and a bowl of water are all you need to start… ...

Compass apps haven’t changed much over the last ten or so years. They use your device’s accelerometer to detect direction. They sometimes need calibration, and magnetic cases can mess with them.
