Celebrating 200 Years of Rudolph Clausius

It was Rudolf Clausius, a professor at the University of Bonn, who in the mid-1800s coined the term entropy, formulated the second law of thermodynamics, and laid the foundations of modern Physical and Theoretical Chemistry - a true transdisciplinary scientist and visionary thinker who cautioned us more than 130 years ago to utilize nature's resources in a sustainable fashion. This year we have commemorated his 200th birthday with a series of academic events.
