"Uncovering a Startling Exception to a 200-Year-Old Law of Physics"

Researchers have discovered that the 200-year-old Fourier's Law of heat transfer might have exceptions when it comes to transparent and translucent materials. By testing translucent polymers and inorganic glasses in a vacuum, they found that heat can transfer through radiation in addition to conduction, which Fourier's Law alone cannot explain. This research provides a new understanding of heat transmission and could lead to new strategies for designing heat circuits.
