Einstein, who was an assiduous reader of the great German philosophers, does not mention at all that he would have read a single line of the philosopher Hegel: what could appear very curious. Especially since in his courses, collected and published under the French title La raison dans l'Histoire, Hegel mentions by name the name that made the glory of the Punu in the 16th century: Jaga or Yaka, in the Germanized form of Dschags or Draks. The present booklet masterfully demonstrates that the Old Man of whom Einstein spoke, according to the great American physicist Heinz Pagels, was more than a mere fictional character; he was a very real African scientist, Master of the scientific paradigm of theoretical physics of the Punu of Moabi-Lu'ng, inventor of the nuclear weapon. And it is this scientist who would have secretly trained Einstein in Germany itself: bringing him to that very dizzying level of knowledge in theoretical physics that he managed to reach. Einstein was deeply affected by the death of the puny old man, and this would explain his inability to follow the evolution of physics from 1926 until his death.
