Ateneo student builds chemical purity tester using Lego bricks
Using simple circuitry, polarizing film, and Lego toy bricks, an undergraduate physics student from the Ateneo de Manila University recently built an improvised polarimeter that can optically assess the purity of Vitamin C (ascorbic acid) and other chiral substances. The device has potential applications in classrooms as a learning tool, and may pave the way […]
