Rob Raeside's final lecture?

On 13 April, Rob Raeside gave the final lecture of his career in the Tectonics class and handed in his red pen. Entitled "The Evolving Earth", he reviewed the evolution of sedimentation, magmatism and metamorphic processes through 4+ billions years of time with speculation of how plate tectonics (and life) might end in the future!
