Popper’s Propensity Interpretation of Quantum Physics as a form of Modal Metaphysics

Basilis S. Dzelajei — Mon, 10 Jul 2023 00:00:00 +0300

With the emergence of quantum physics in the 1920s, the major philosophical question was, do the unobservables in quantum system have ontological status or are mere instruments for scientific prediction? The Copenhagen interpretation developed an instrumentalist thesis, contending that the unobservables are tools for making predictions concerning the observables. Thus, we cannot have knowledge of the quantum particles. However, Popper attempts a realist and an objective interpretation. As such, he criticizes the Copenhagen interpretation, developing the propensity view, which accords ontological status to subatomic particles. The main thrust of our argument in this paper is that by replacing probability possibilities with propensities, Popper positions himself as a proponent of the metaphysics of modality. It is then our objective to establish the parallelism between Popper’s Propensity Interpretation and Modal Metaphysics. To establish this contention we proceeded analytically: firstly by situating the seismic shift from macro to quantum physics, secondly by examining Popper’s critique of the Copenhagen Interpretation and thirdly by attempting a demonstration of the correlation between Popper’s propensity interpretation and modal metaphysics. The merit of this paper resides in its elucidation of the importance of metaphysics in science. It is a double challenge at the same time for antimetaphysical philosophy of science and for antiscientific metaphysics, to rethink the relationship between Metaphysics and science and invest in finding how both disciplines nurture each other. Finally, it is hoped that policy makers in Philosphy and science uses our findings to revamp the conceptualisation and practice of interdisciplinarity.

Multichannel Frequency Selective Seismograph Graphical User Interface (GUI)

Purpose: The research discusses the programming and setup of a frequency-selective Graphical User Interface (GUI) for a seismograph.

Materials and Methods: GUI was developed using Visual Basic Net with C language and Dundas Software which serves as the interface between the hardware system and the laptop to display real-time signals sent by the geophones. The studies conform to the feature of standard simulation and assist the users to perform a system-level simulation and reception of data from the geophones.

Findings: It allows the users to choose frequencies between the available frequencies, design a layout, and view the results. Users can choose and read the output display, making the measurements easy to record.

Implication to Theory, Practice and Policy: The GUI is explained with respect to the graphical layout and the interactive features of the components. The GUI picks from the low Band frequency cutoff of 1.989 x 10^-5Hz, 1.061 x 10^-3Hz for High Pass and Band-Pass cut-off.

Calculating All Dark Energy and Dark Matter Effects through Dynamic Gravity Theory

Newton’s Universal Law of Gravitation was augmented by Einstein’s General Relativity to include factors such as time dilation from speed and gravity field strength. But this augmentation has proven to be incomplete as the math fails in almost all settings outside our solar system hence the need for Dark Energy and Dark Matter to resolve the math. Dynamic Gravity has new math that augments GR in much the same way GR augments Newton’s Law, and this math has the potential to completely explain the motions of all celestial bodies throughout the entire universe with zero need to correct the math with Dark Matter or Dark Energy. This paper explores the notion that gravity must obey the law of conservation of energy as all other forces in this universe have been shown to do. Explaining exactly what gravity is and how it manifests itself on a sub-atomic level. And explaining the many different implications that would be created from this theory. And finally using the math of Dynamic Gravity to calculate Dark Energy and Dark Matter effects within the Milky Way, and between the Milky Way and Andromeda to explain observations without the need of exotic measures.
