Standing waves in your coffee mug

Tomorrow Tuesday November 12 at 7am-12am, construction work will take place outside the department office at the third floor. The work involves drilling in the concrete floor and ceiling and is expected to be noisy. If you expect that your office will be in the noise zone, you may consider taking suitable precautions for this time slot (work from home, work in the lab if the lab is more distant, work in the library, wear ear protection etc). Please inform those who needs to know your whereabouts.

Sorry for the inconvenience!
