ZA_1_16 — Sonoluminescence: Light from Sound and the Mystery of Collapsing Bubbles

Sonoluminescence is the emission of short bursts of light from gas bubbles in a liquid when excited by ultrasonic sound waves. First observed by H. Frenzel and H. Schultes at the University of Cologne in 1934 (multi-bubb

ZA_4_04 — Plasma Physics: The Fourth State of Matter

Plasma — ionized gas in which electrons are stripped from atoms — constitutes over 99% of the visible matter in the universe. Stars, nebulae, the interstellar medium, lightning, and the solar wind are all plasmas. Unlike
