He graduated high school and ranked first place in the official exams of the baccalaureate Section II (general science) in Lebanon.
He had a thesis that it subject addressed as follows: "The importance of statistical mechanics to explain the energy distribution in solids transparent (amorphous) spiral shape using numerical methods", this thesis was discussed in front of 16 scientists, senior physicists in France and it was a subject of appreciation and admiration prompting then the French Prime Minister Jacques Chirac to meet student researcher Rammal Rammal.
Rammal became famous all around the world, he went to many important universities in the United States as a visiting professor and an especially in the US space agency, "NASA".
During 1983–1984, Rammal served as a visiting professor for six months in Nuclear Physics, co-managing the University of Pennsylvania in Philadelphia Research Department (United States) and Brookhaven National Laboratory in Upton, New York.
Dr. Rammal has published 113 scientific researches in the topics of statistical physics research (Mathematics, thermodynamic, laws of motion applications specific heat in solids, liquids and gases, molecular hydrogen gas behavior in the lower temperature limits, extreme behavior of nuclear particles in the microscopic tropical systems, characteristics of the Fermi-Dirac statistics, etc.
