| | | | | [AI summary] The text discusses the implications of quantum mechanics and the concept of expected energy in quantum systems. It highlights the difference between the average energy of a quantum state and the energy of the system post-measurement, emphasizing that the former is a statistical average while the latter is determined by the measurement outcome. The discussion also touches on the broader context of quantum theory, including the role of measurement and the probabilistic nature of quantum states. Additionally, it references the importance of energy in physical processes and the connection to classical thermodynamics, suggesting that while quantum mechanics provides a framework for understanding energy at a fundamental level, classical concepts still... | |

| | | | | 4gravitons has proposed a challenge: To explain scientific papers appearing on arXiv on a given day in a given (sub)field to a general audience. The challenge is directed towards fellow science communicators so that definitely excludes me. But one of my old year thoughts (turned to a new year resolution) for this blog was to... | |

| | | So, Part II of my two-part series for American Scientist magazine about how to recognize random numbers is now out. This part---whose original title was the one above, but was changed to "Quantum Randomness" to fit the allotted space---is all about quantum mechanics and the Bell inequality, and their use in generating "Einstein-certified random numbers." | ||
