Like a tiger’s stripes, Jupiter’s colorful bands are more than just pretty colors

Jupiter: The Large Adult Son of the Solar System

“We are really learning about a brand new Jupiter in many ways.”

For The Daily Beast:

Everything about Jupiter is large. The planet’s diameter is 11 times Earth’s size, and it is more massive than all other planets, dwarf planets, asteroids, comets, and moons put together. Jupiter’s Great Red Spot is a storm bigger than Earth that has lasted for as long as we humans have built telescopes to see it.

Jupiter’s mysteries are also large. NASA’s Juno mission currently in orbit around the planet is teaching us that we really don’t understand the solar system’s large adult son. Four new papers published in Nature on Wednesday outline the strangeness of Jupiter’s atmosphere, and how none of our current theories about how planets work are adequate to explain that weirdness.

Swarming in time, synchronizing in space

This article is a little different from the fare you’re used to getting from me: it’s for SIAM News, which is the glossy magazine for members of the Society for Industrial and Applied Mathematics. The audience for this magazine, in other words, is professional mathematicians and related researchers working in a wide variety of fields. In this case, I covered research by mathematicians looking at a type of system that occurs in biology and materials science. While the article contains equations, I wrote it to be understandable if you skim that part.

Self-organization in Space and Time

For SIAM News:

Self-organization is an important topic across scientific disciplines. Be it the spontaneous flocking of birds or dramatic phase transitions like superconductivity in materials, collective behavior without underlying intelligence occurs everywhere.

Many of these behaviors involve synchronization, or self-organization in time, such as activation in heart cells or the simultaneous blinking of certain firefly species. Others are aggregations, or self-organization in space, like swarming insects, flocking birds, or the alignment of electron spins in magnetic material.

Despite their conceptual similarity, self-organization in space and time have largely been treated separately. “I was curious about whether the two fields had been wedded, and it turns out they hadn’t, at least not fully,” Kevin O’Keeffe, a postdoctoral researcher at the Massachusetts Institute of Technology, said. “I knew all these tricks and mathematical tools from synchronization, and I was looking to cross-fertilize them into the swarming world.”
