GNU Radio – the Free and Open Software Radio Ecosystem
GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available, low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic, and commercial environments to support both wireless communicationsContinue reading “GNU Radio – the Free and Open Software Radio Ecosystem”
Is Space Pixelated? The Quest for Quantum Gravity
The universe itself may be similarly pixelated. Scientists such as Rana Adhikari, professor of physics at Caltech, think the space we live in may not be perfectly smooth but rather made of incredibly small discrete units. “A spacetime pixel is so small that if you were to enlarge things so that it becomes the sizeContinue reading “Is Space Pixelated? The Quest for Quantum Gravity”
