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

Weird. Look at the map… That sure is something.

In the meantime, scientists are working to understand why the magnetic field is changing so dramatically. Geomagnetic pulses, like the one that happened in 2016, might be traced back to ‘hydromagnetic’ waves arising from deep in the core1. And the fast motion of the north magnetic pole could be linked to a high-speed jet of liquid iron beneath Canada2.

Wurzeln der Weihnachtsgeschichte: Syrien, Magus, Römer, Nazareth und Bethlehem – und Caesar und Alexander

Reality update: Wie ein syrischer Religionslehrer Jesu’ Geburt erfand | Telepolis … :

Wer sich auf die Geschichte hinter der Weihnachtsgeschichte macht, der landet zunächst nicht in einem Bethlehmer Stall, sondern im heutigen Syrien. Circa im Jahr 90 nach Christus, also nach heutigen Erkenntnissen rund 60 Jahre nach Jesu tatsächlichem Tod, lebte dort ein Religionslehrer mit seiner kleinen judenchristlichen Gemeinde: der Evangelist Matthäus.

#MIT #AI able to understand basic laws of physics

Reality update: Helping machines perceive some laws of physics | MIT News … :

Humans have an early understanding of the laws of physical reality. Infants, for instance, hold expectations for how objects should move and interact with each other, and will show surprise when they do something unexpected, such as disappearing in a sleight-of-hand magic trick. Now MIT researchers have designed a model that demonstrates an understanding of some basic “intuitive physics” about how objects should behave. The model could be used to help build smarter artificial intelligence and, in turn, provide information to help scientists understand infant cognition.
