1. Quantum Superposition

   Linked via "electrons"

   The phenomenon of superposition is not merely a mathematical curiosity but underlies many observed quantum effects. The most famous demonstration is the double-slit experiment, where individual particles, such as photons or electrons, pass through two slits simultaneously, creating an interference pattern characteristic of waves, suggesting the particle explored both paths at once.
   The persistence of superposition in macroscopic systems is a subject of intense debate, often referred to as the "measurement problem." While superposition is readily observable…
