The sun is the roundest natural object known to humans, according to new research. University of Hawaii researcher Jeffrey Kuhn and his colleagues used NASA's space-based Solar Dynamics Observatory to precisely measure the sun's shape. A precise understanding of the sun's roundness and the factors that shift its shape, such as sub-surface turbulence, could shed new light on changes in the Earth's climate. From National Geographic:
If the sun were a meter-wide (3.3-foot-wide) beach ball, Kuhn said, the variation in the sun's shape from the highest to the lowest point would be about 17 microns—less than the width of a fine human hair, according to the SDO measurements…
Study leader Kuhn said his team is going to update computer models of the sun's cycle to see if and how the highly accurate shape affects their behavior.
"We're not done with measurements, though. We need to follow a full 11-year solar cycle to make sure the sun isn't fooling us," Kuhn said. "By doing that we can improve the accuracy even further."

I asked Amy Parness, the co-founder of Sparkle Labs, maker of fantastic educational electronics kits, to write a Medium post about gender and the business of being a maker business person. Her terrific essay calls out the problems with “pink girly engineering kits.” From Medium:
Zero UI is the new term for “invisible interfaces”—what happens in the future when all the clicking and tapping and typing is history: “If you look at the history of computing, starting with the jacquard loom in 1801, humans have always had to interact with machines in a really abstract, complex way.” [Fast Company]
