The next PPS Seminar on Physics will be held on April 8, 2021 at 16:15, online on the MS TEAMS platform.
Prof. Paweł Olko and Prof. Adam Maj (IFJ PAN Krakow) will present: “Cyclotron Center Bronowice – five years of applied and basic research in proton therapy center”.

The Josephson effect is a quantum phenomenon appearing in superconductors.
It consists in the spontaneous flow of electric current, due to tunneling, between the two
superconductors separated by a thin insulator layer. The current flow is induced by
phase difference of wave functions describing superconducting electrons on both
sides of the insulator. This is called the Josephson junction.
The phenomenon occurs in metals as well as in ultracold atomic gases.
Search for the Josephson effect in nuclear systems
have been going on for almost half a century.
Theoretical analysis of recent experiments involving collisions of Nickel-60 and Tin-116
provided strong arguments for creation of the Josephson junction.
Contrary to the previous measurements where
the pair transfer cross section has been investigated, this time the gamma radiation spectrum
was analyzed. It turned out that the spectrum of emitted gamma rays agrees with the theoretical
predictions assuming the formation of the so-called AC Josephson junction.

Is the physics of the 21st century a simple continuation of the twentieth-century physics, or have its new methods, theoretical approaches and research areas revealed? Have the discoveries, hypotheses and experiments of the past two decades violated the typical philosophical interpretations within ontology, natural philosophy and philosophy of science?
Aware that many more similar questions can be asked, we invite you to participate in the conference.
XVII National Conference on the Philosophy of Physics on:
PHYSICS OF THE 21ST CENTURY AND NEW PHILOSOPHICAL CHALLENGES
March 5, 2021, remote mode on Teams
Organizers: Faculty of Philosophy and Faculty of Physics at the University of Adam Mickiewicz in Poznań
Patronage: Poznań Branch of the Polish Philosophical Society and Poznań Branch of the Polish Physical Society
