<font size=4><b>Object Lessons: Amazing Bubbles</b></font><br><br>
Physicists invented a way to see the unseen by filling a pressurized
chamber of liquified <br>
gas in which otherwise undetectable particles would create telltale
streaks of bubbles as <br>
they passed through. MIT professor emeritus Irwin Pless helped design one
of the first <br>
bubble chambers when he was a graduate student at the University of
Chicago. Come to <br>
this monthly brown bag gallery talk and learn about experimental physics
and the MIT <br>
Museum's iMethyl-Iodide Bubble Chamber that Pless built with the
Cambridge Bubble <br>
Chamber Group in 1960. Moderated by Deborah Douglas, MIT Museum
curator of science <br>
and technology. <br><br>
* Noon - 1:00pm at the MIT Museum<br>
* Free admission; refreshments provided<br>
* General audience</blockquote><br>
