Adult birds develop navigational maps inside them to help them travel to faraway lands. How this happens is still a mystery and various theories are being considered: infra-sound, smells, and gravity variations.
A theory gathering some evidence is that the earth’s magnetic field forms a grid that is followed by the birds.
Studies done on the reed warbler (Acrocephalus scirpaceus), a Eurasian migratory bird, provide clear evidence of the magnetic field.

Billions of songbirds migrate every year to different lands thousands of miles away, and the way they reach the exact same place to nest is fascinating and is as if they have precise GPS instruments installed in them.
This mysterious sense of compass direction is due to a ‘magnetic map’ that is very much like the way we use GPS (Cartesian coordinates).
Third-person self-talk may constitute a relatively effortless form of emotion regulation.
Referring to yourself in the third person leads you to think about yourself more similar to how you think about others. And that helps you to gain psychological distance from your own experiences.
Contactless payments would never have been possible if we didn't have satellites. Literally, all of our financial transactions rely on satellites' locations and timing services for security purposes as well.
If the satellite's timing isn't in sync with the others, it is possible for money to be lost in the transaction.
Since National Geographic began making maps in 1915, it has recognized four oceans: the Atlantic, Pacific, Indian, and Arctic Oceans. Starting on the World Oceans Day 2021 (June 8) it has also recognized the Southern Ocean as the world’s fifth ocean.
It has long been recognized by scientists, but the lack of an international agreement kept the editors from formally adding it to the list.
