It's not easy being clean. Although they might be invisible to the naked eye, contaminants less than a micron in size can ruin very sensitive experiments in particle physics. Flakes of skin, insect parts and other air-surfing particles--collectively known as dust--force scientists to construct or conduct certain experiments in cleanrooms, special places with regulated contaminant levels. There, scientists use a variety of tactics to keep their experiments dust-free. The enemy within Cleanrooms a...
