Professor Roald Hoffmann, Nobel Prize in Chemistry in 1981, has been received today, January 19, 2023, at the GPS® laboratories by his director, Dr. Antonio Martínez-Murcia. Dr Roald Hoffmann has traveled from New York to present his book of poetry Los hombres y las moleculas, accompained by Professor Santiago Alvarez Reverter, University of Barcelona. Spanish translation by the Oriolan publishing house Auralaria Ediciones, and in whose printing GPS® has collaborated. We are particularly proud/grateful that the proposal/idea, forged in GPS®, to make Professor Hoffmann’s visit to present the book in person, has come to fruition.
