High school student Jasmine Wu won first place in the Contrived category of @AAPTHQ’s High School Physics Photo Contest for her photo of Epsom salt undergoing birefringence. When viewed through a DIY polariscope, the high-resolution image evokes the surface of a planet beyond our own. #backscatter

If you’ve ever produced a tone by blowing a stream of air across the mouth of a bottle, you’ve used what’s known as a Helmholtz resonator. Now researchers have found a way to harness that resonance effect to propel miniature boats and aircraft. #physics #acoustics

Navigating the academic job market is always stressful, and doing so as a couple raises the stakes. Toni Feder spoke to couples about their strategies and experiences, what help institutions provide, and what sorts of solutions they’ve found—including when it’s time to walk away. #careersissue

Dylan Spaulding’s shock-wave studies on minerals to understand planetary formation had significant overlap with research on stockpile stewardship of nuclear weapons. Now he applies that knowledge at the Union of Concerned Scientists to work toward nuclear disarmament. #whatcanphysicistsdo

The quantum world is full of counterintuitive phenomena. Using a vortex to scatter standing waves in water, researchers showed how classical fluids can serve as laboratories for visualizing quantum effects that may be much harder to observe in quantum systems. #BackScatter #quantum
