Letter Regarding Nuclear Power Work in Hamburg, Germany

In this letter to his friend, German chemist Karl Friedrich Bonhoeffer, Paul Harteck writes about the work he's been doing at the Hansischen University in Hamburg, Germany. The letter details the work on nuclear energy, namely the separating of metal tubes and low-pressure columns, which gave "higher separation efficiencies" between atoms. The letter concludes with Harteck calling this the "high art of experimentation."
