Researchers have created an ultra-thin film that can absorb almost all electromagnetic waves across several frequency bands, significantly boosting the performance of wireless communication devices.
Many physical phenomena – including heat transfer, fluid flow and electromagnetic wave propagation, to name just three – can be described using partial differential equations (PDEs). Apart from a few ...
Einstein's theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that remains is "gravitational wave memory"—the prediction that a passing ...
