Autor/Autorin

Eugenio Mieli

Claudio Maccone is a SETI astronomer, space scientist and mathematician. From 2012 to 2021 he chaired the SETI Permanent Committee of the International Academy of Astronautics (IAA) which is based in Paris. Author of over 100 scientific articles, he published 6 books about future Space Missions, SETI and Astrobiology. He is now Chair of the IAA Moon Farside Protection Permanent Committee which aims to preserve (at United Nations) the radio silence still existing on the other side of the moon, before it is destroyed by the political rivalries between the various spatial countries today.

Andrea M.F. Valli, biophysicist and paleontologist. He was scientific advisor for the "Conseil général de l’Allier”. Associated with the "Société Scientifique du Bourbonnais" (Allier), he participated in the cultural dissemination with conferences on paleontology and the evolution of life.

Eugenio Mieli, degree in physics. He has always worked in TLC. Noting the relevance between Maccone's work in the book "Mathematical Seti" and the biological scenario described by Valli in the book “Bactéries, Dinosaures et Kangourous - Brève Histoire de la Biodiversité”, has decided to face Drake's entire equation together with the two other authors.
