Polarized scattering experiments reveal that quarks contribute surprisingly little to the proton's spin. Two decades of solar seismic studies have let us peek inside the Sun.
Researchers report evidence for lasing without inversion.
Accomplished violinists can generate anomalous low frequencies on their instruments. These unusual tones can be understood in terms of multiple reflections of a single wave at the bow. In effect the reflections prolong the sound-producing cycle first analyzed by Helmholtz. Satellite mapping of terra incognita provides welcome relief. As reports of the employment woes of young PhDs trickle up to the leaders of the physics community, some faculty members and science organizations hasten to reform graduate education.
