Many-body Memes

When you've been struggling with full many-body quantum calculations for weeks and suddenly remember Kohn-Sham equations exist! The heavenly glow is 100% accurate - these equations are basically the guardian angels of quantum chemistry. They transform an impossible many-body problem into a set of single-particle equations that mere mortals can actually solve. It's like trading in your bicycle for a jetpack when you're late to a conference. Computational chemists worship at this altar for good reason!
