From international laboratories to elite training, the Sicilian physicist has transformed research, method and dissemination into real strategic levers

The disappearance of Antonino Zichichi In Lausanne on February 9th, one of the most recognizable trajectories of Italian science in the second half of the twentieth century came to a close. A theoretical and experimental physicist, organizer of research networks, and a popularizer and promoter of advanced training, the Sicilian scientist acted on a key area in today's innovation processes: the connection between cutting-edge research, international infrastructure, and cultural transfer to society. His legacy is measured not only in his scientific achievements, but also in the construction of knowledge ecosystems capable of lasting over time.

After his education in physics and the beginning of his academic career, avowedly Catholic, he worked in the field of fundamental interactions, participating in experimental programs of nuclear and subnuclear physicsHe was a professor at theUniversity of Bologna, where he contributed to the growth of research groups with a strong international outlook. He worked in large European and American laboratories, such as the CERN in Geneva and FermiLab in Chicago, at a time when high-energy experimentation required complex facilities, accelerators and structured multilateral collaborations.

During his career he held top positions in scientific governance: President of the National Institute of Nuclear Physics, from the Enrico Fermi Study and Research Center and European Physical Society and World Federation of Scientists and World LaboratoryThese roles placed him at the crossroads of scientific direction, research diplomacy, and infrastructure planning. At the national level, he was a proponent of system-wide research, based on the integration of universities, public institutions, and large experimental facilities.

High Energy Physics and Large Shared Infrastructures

During his career he has worked within the main infrastructures of the high energy physics, contributing to the development of international collaborations when European science was defining its competitive space with respect to the United States. The model of large laboratories, based on transnational cooperation, large-scale data sharing and instrumentation, is today considered a prototype of modern open innovation systems.

We also owe him the idea and the realization of the Gran Sasso National Laboratories, one of the world's largest underground facilities for astroparticle physics and ultra-low-noise experiments. The facility represents a prime example of long-term investment in big science with widespread scientific and technological returns.

Antonino Zichichi supported the construction of large European accelerators, contributing to the scientific push that led to machines such as LEP at CERN and HERA at DESY in Hamburg. Already at the end of the 1970s he proposed a supercollider for protons called ELOISATRON, a visionary project that conceptually anticipated the evolution of very high energy colliders and is often cited as a precursor to the architectures being studied today for future post-LHC machines.

According to European analyses published in recent years, large-scale shared scientific projects generate technological spillovers in fields such as sensors, high-performance computing, and new materials. In this context, its activity has helped strengthen the idea of research as a strategic infrastructure and not as an isolated sector.

Experimental results and advanced detection technologies

On the experimental level, with his research groups he has achieved significant results in subnuclear physics. Among the most cited are the observation of theantideuteron, among the first examples of nuclear antimatter, together with studies on phenomena of the quantum chromodynamics, such as the Leading Effect and the concept of effective energy in high-energy collisions. The programs he contributed to have participated in the identification of new heavy baryonic particles associated with the quantum number beauty, in a phase of expansion of quark physics.

A lesser-known but strategic part of his work concerns instrumentation development. He promoted research and development activities on new particle detection techniques within CERN programs, leading the development of multigap resistive plate chambers for extremely precise time-of-flight measurements. These detectors still constitute the experiment's TOF system. ALICE al Large Hadron ColliderIt is a concrete example of how fundamental research produces reusable hardware innovation on multiple fronts.

Particle physics anticipated dynamics now common in other deep tech sectors: large, distributed teams, long investment cycles, and a strong integration of theory, experimentation, and engineering. These environments also function as training grounds for transferable skills: managing complex systems, experimental validation, and protocol standardization.

Erice and an original model of global scientific education

One of the pillars of his legacy is the creation of the “Ettore Majorana” Center di Erice, a permanent platform for advanced training and interdisciplinary discussion. Founded in the 1960s and progressively expanded, it has hosted thousands of researchers and professors from numerous countries, with schools dedicated to physics, medicine, energy, computer science, and materials science. Born in Trapani on October 15, 1929, Antonino Zichichi transformed Sicily into a stable hub of international scientific exchange.

The model (thematic schools, world-class teachers, select groups) anticipates the current emphasis on advanced interdisciplinary training and networks of expertise. Industry data indicates that intensive residential programs generate higher rates of subsequent scientific collaboration than traditional pathways, thanks to the creation of lasting professional connections.

Sicily has also been the site of global cooperation initiatives. The Erice Manifesto of 1982, drafted with two Nobel Prize winners, Paul Dirac and Piotr Kapitza, laid the foundations for a reflection on science as a tool for international dialogue and nuclear risk reduction, contributing to the emergence of practices of scientific diplomacy widely recognized today.

Dissemination, method and public responsibility of science

The Sicilian scholar was one of the most recognizable science communicators in Italy, author of numerous volumes and a constant presence in the press and television. His work aimed to build a systemic narrative of science, focused on the experimental method, verification, and social responsibility. Particular emphasis was placed on works dedicated to the history of physics and the figure of Galileo Galilei, used as tools for teaching the method.

Recent European surveys on public perception of research show that trust increases when communication is continuous and structured. This is also the position expressed several times by Fabiola Gianotti, Director General of CERN, according to whom great research produces full value when it spreads methods and expertise beyond the laboratories. This vision is consistent with the educational approach promoted by Professor Zichichi.

From big science to mission-driven innovation models

A particularly timely aspect of his contribution concerns the so-called big science model, which has once again become central to industrial and technology policies. Large-scale coordinated programs (accelerators, underground laboratories, detector networks) operate according to logics found in modern mission-driven strategies: clear objectives, multi-decade horizons, patient investments, and public-public and public-private cooperation.

In recent years, both at European and Swiss level, strategic documents on critical technologies and scientific sovereignty have reiterated that research infrastructures are enabling assets of industrial innovationNot only do they produce knowledge, but they also develop rare skills, generate specialized supply chains, and push technological standards that then spread to the market. The approach he advocates (concentrating resources on excellent scientific platforms and highly qualified communities) anticipates this approach.

Even Antonino Zichichi's insistence on centrality of fundamental research This finding finds renewed confirmation today. Economic analyses of innovation published in recent years show that a significant share of high-impact patents arise indirectly from publicly funded basic research. The return is neither linear nor immediate, but systemic: skills, tools, and methods. It's the same pattern that characterized particle physics between the 1960s and 1990s.

In this sense, the trajectory of the Italian scientist helps to understand the current transformation of the deep tech hubs: less isolated innovation, more collaborative architectures; fewer single laboratories, more integrated networks; fewer short-term projects, more sustainable infrastructure. A paradigm that today guides sectors such as quantum computing, space, and advanced energy technologies.
