In this issue: April 2024.

The April 2024 issue of the American Journal of Physics features a variety of articles covering topics in physics. One article provides an overview of dark matter, discussing its historical evidence, possible candidates, and detection techniques. Another article explores relativistic acceleration in noninertial frames, analyzing scenarios with differences in proper time elapsed and spacetime events. A third article discusses a method for calculating wavefunctions in quantum mechanics without differential equations. Other articles cover topics such as stochastic trajectories, Brownian motion, first passage time distribution, Young's double-slit interference, and using Minecraft for learning digital electronics. These articles offer valuable insights and experiments for students and researchers in the field of physics. [Extracted from the article]
