Spectra #4

Spectra Heats Up! is the fourth installment of APS Physics' engaging educational series, and this free 2012 issue looks like a lively one. The cover spotlights Spectra in her bright superhero costume, front and center, while a group of curious, diverse teens looks on in the background against a school setting. It's a welcoming, energetic package that makes physics feel genuinely accessible and fun.
