In chemistry and physics, the exchange interaction (with an exchange energy and exchange term) is a quantum mechanical effect that only occurs between identical particles. Despite sometimes being called an exchange force in an analogy to classical force, it is not a true force as it lacks a force carrier. The effect is due to the wave function of indistinguishable particles being subject to exchange sym… WebMar 10, 2024 · A large, Chinese-linked hack of Microsoft's Exchange email service continues to spread alarm, a week after the attack was first reported.
