Tacoma bridge Memes

Engineering professors have exactly two examples in their repertoire: the pendulum and the Tacoma Narrows Bridge collapse. You can set your watch by it. First day of class: "Let's discuss simple harmonic motion." Week 7: "Remember how the Tacoma Bridge oscillated itself into oblivion? No? Let me show you the footage for the 47th time." The cycle continues, semester after semester, like a perfectly damped oscillator.
