Vahala California Institute of Technology‚ Mail Stop 128-95‚ Pasadena‚ California 91125‚ USA (e-mail: vahala@caltech.edu) Optical microcavities confine light to small volumes by resonant recirculation. Devices based on optical microcavities are already indispensable for a wide range of applications and studies. For example‚ microcavities made of active III–V semiconductor materials control laser emission spectra to enable long-distance

the message is more then what the words say. The idea of modularity gave rise to the letterpress technology and also influenced the shape of graphic design‚ establishing principles that were crucial to later industrialization.

Crystal making lab Purpose: To better understand saturated solutions‚ solubility . Analysis: 2. Why was it necessary to heat the water? Be specific. Heating the water allows it to hold much more borax in solution than it could at room temperature. So after the water cooled‚ the ability of the solution to hold the solute inside decreases‚this causes the excess borax in the solution to precipitate in crystal form on the string.When the water at a high temperature‚ water molecules have more kinetic
