Yes, it is possible to interpret Whitehead's influence by quantum physics as an implicit zeitgeist of the time. A zeitgeist refers to the general intellectual and cultural climate of a particular era, and it is often characterized by the prevailing ideas and values of the time.
In the 1920s, quantum physics was a rapidly developing field that was challenging traditional ideas about reality and the nature of the universe. Scientists such as Niels Bohr, Werner Heisenberg, and Erwin Schrödinger were developing new theories and experimental techniques that revealed a world that was fundamentally uncertain, indeterminate, and interconnected.
Whitehead was a philosopher who was interested in exploring the implications of these new scientific discoveries for our understanding of reality. He was part of a broader movement of thinkers who were seeking to reconcile the insights of science with the traditional philosophical questions of metaphysics and epistemology.
Whitehead's ideas about process philosophy and the interconnectedness of reality were influenced by the new discoveries of quantum physics. His concept of "actual occasions" as the basic building blocks of reality, for example, can be seen as analogous to the quantum mechanical idea of particles as discrete packets of energy that are constantly interacting and changing.
Overall, while Whitehead's influence by quantum physics may not have been a direct or explicit one, it is certainly possible to see it as an implicit zeitgeist of the time. Many thinkers in the 1920s were grappling with the implications of quantum mechanics for our understanding of reality and the nature of the universe, and Whitehead's philosophy can be seen as a response to this broader intellectual and cultural climate.
