Ironing out the mystery of Earth’s magnetic field

Scientists directly measure thermal conductivity of iron at planetary core conditions for the first time The earth’s magnetic field has been existing for at least 3.4 billion years thanks to the low heat conduction capability of iron in the planet’s core. This is the result of the first direct measurement of the thermal conductivity of…

How plasma connects the Sun to the climate

 Guest essay by Robert Johnson How plasma connects the Sun to the climate The Aurora Borealis (Northern Lights) are a plasma phenomenon caused by charged particles from the solar wind entering the Earth’s upper atmosphere. Magnetic storms in the ionosphere, which have occasionally damaged satellites in orbit, are also evidence that the Earth’s upper atmosphere…

Anthropocene – The New Pop Religion

Steve Harris writes: An article came out on the AIP Physics Today website about a push from some scientists to formally designate today’s human geological epoch as the “Anthropocene”. Editors of the journal Nature argue that the name “provides a powerful framework for considering global change and how to manage it.” Here is a link:…
