This essay is based on the science project I am involved in as a duplicator of the nuclear physics experiment. The beam-split-like coincidence counting experiment with gamma-rays was invented by the American electrical engineer Eric Reiter in early 2000. The experiment, which I eventually started to call the Tandem Piercer Experiment, raises down-to-earth questions about the wave-particle duality, the early development of the atom model, the concept of a photon, and quantum mechanics. These questions are highly controversial in dissident science and brought me, as a layman, to the center of the sociological questions on how theories evolve in physics society and how science works. A lot of this controversy is dealt with polemically in the essay in conjunction with the overall description of the Tandem Piercer Experiment. I wish to present this authentic original work of Reiter as a delicate citizen science project. It is open to theoretical and philosophical speculation and calls for participation.
