Your brain when facing a deadline: "Let's ignore this urgent assignment and instead contemplate the Bose-Einstein condensate energy equation! Because nothing says 'productive procrastination' like suddenly becoming fascinated with quantum statistical mechanics."
That equation describes the internal energy of a Bose gas, but your internal energy is being wasted on literally anything except the paper due in 30 minutes. Classic academic brain - suddenly finding quantum physics irresistibly interesting only when there's something more important to do.
