On Science Friday, Prof. David Kaiser speaks with Ira Flatow and Annie Minoff about Albert Michelson, a physicist who was known for his work trying to detect evidence of the luminiferous ether, the hypothetical matter that for years scientists believed light traveled through.
Xinhuanet highlights a new system developed by MIT Professor Marin Soljačić and graduate student Yichen Shen that allows for filtering light waves based on direction. This research could have major implications for solar energy technology.
New Scientist reporter Jacob Aron reports on how MIT researchers have developed a new system that filters light waves based on the direction they are traveling. The system could be used to take photographs of faint objects, Aron writes.
