Earth: Magnetic Field

Earth’s magnetic field is acting up and geologists don’t know why

Erratic motion of north magnetic pole forces experts to update model that aids global navigation. 
Update, 9 January: The release of the World Magnetic Model has been postponed to 30 January due to the ongoing US government shutdown.

Something strange is going on at the top of the world. Earth’s north magnetic pole has been skittering away from Canada and towards Siberia, driven by liquid iron sloshing within the planet’s core. The magnetic pole is moving so quickly that it has forced the world’s geomagnetism experts into a rare move.

On 15 January, they are set to update the World Magnetic Model, which describes the planet’s magnetic field and underlies all modern navigation, from the systems that steer ships at sea to Google Maps on smartphones.

Boxing Day 2018

What Is Boxing Day and How Did It Get Its Name?

Arguments abound on the origins of the name Boxing Day. All the answers below are valid, so maybe it is one, or even all of them.
  1. The name is a reference to holiday gifts. A ‘Christmas Box’ in Britain is a name for a Christmas present. Boxing Day was traditionally a day off for servants and the day when they received a ‘Christmas Box’ from the master. The servants would also go home on Boxing Day to give ‘Christmas Boxes’ to their families.
  2. The name is a reference to charity drives. A box to collect money for the poor traditionally and placed in Churches on Christmas day and opened the next day - Boxing Day.
  3. The name refers to a nautical tradition. Great sailing ships when setting sail would have a sealed box containing money on board for good luck. Were the voyage a success, the box was given to a priest, opened at Christmas and the contents then given to the poor.
