Take a peek inside a flickering candle flame with these 3D-printed shapes

New research from MIT explores fire from a whole series of new perspectives. The research uses deep-learning approaches that extract the vibrational features of flames as flickering objects and, in turn, renders them into sounds and materials. The 19th-century physicist Michael Faraday was known not only for his seminal experimental contributions to electromagnetism but also […]
