Particle in a Box Part 1: Solving the Schrödinger Equation
Now that we understand the Schrödinger equation, it's time to put it to good use, and solve a quantum problem. Let's find the eigenfunctions and eigenenergies associated with a quantum particle restricted to an infinite square well. This...

The next step in Earth-like Exoplanet discovery - the blurry images of CHEOPS
It seems counterintuitive, but ESA's newest space telescope, CHEOPS, is designed to take blurry images of stars. But this helps astronomers to understand more about orbiting exoplanets than a clear image would. Here's why!
