- Turbulence ahead: Interstellar wind changes direction, blows faster (Ars Technica): The Solar System orbits the center of the Milky way, and as it does, it’s passing through a diffuse nebula known as the Local Interstellar Cloud (LIC). Various satellites and probes have measured the passage of atoms through the Solar System since the 1970s; analysis of that data shows that the direction of this wind has changed and its rate has picked up. That reveals some interesting new detail about the environment surrounding the Solar System.
- Of maps and math and Buckminster Fuller (Galileo’s Pendulum): Mapmaking will never be perfect because there’s no way to create a flat representation of the curved surface of Earth without some distortions. This post goes a little into the math of projection, the art of converting positions on a globe onto a flat map, and how the eccentric utopian architect Buckminster Fuller tried to solve the problem. The result was his wonderful Dymaxion map, which as a physicist I’m very fond of.
