An object in a binary system defies categorization. Jennifer Sieben Bubble lasers are sturdy and sensitive Made of liquid-crystal films, the soft, air-filled lasers have stable spectra that shift when the bubbles are squeezed. Johanna L. Miller FROM THE VAULT: September 1975 High‐energy gamma‐ray astronomy The highest‐energy particles and processes in the universe provide clear and often unique information on the structure and history both of our galaxy and of the regions beyond. Carl Fichtel, Kenneth Greisen, and Donald Kniffen Webinar Workshop: Engaging Students with Realistic Virtual Physics Labs The first half of this workshop will present a holistic interactive-engagement approach to learning and teaching physics. The second half will introduce virtual physics investigations that include everything a student needs to conduct realistic experiments. Register now.
