Explain physics with the whole instead of particles

28.09.2005


Physicists usually describe the world from the vantage point of its smallest component parts. But quantum theory does not allow itself to be conceptually crammed into such a framework. Instead, in her dissertation at Uppsala University in Sweden, Barbara Piechocinska takes her point of departure in the mathematics of the dynamic whole and finds that time thereby takes on new meaning.

Throughout the centuries reductionist philosophy has reigned supreme in physics. It has been assumed that it is possible in principle to describe the world by finding the tiniest building blocks and understanding how they interact. Not until the early 20th century was this view of the world seriously challenged, by quantum theory. Quantum theory is regarded as one of the most fundamental of theories, explaining, among other things, the stability of the atom, and it is widely used in technology.

“What’s interesting about quantum theory is that it seems to refuse to be shut up inside a reductionist framework. Instead it seems to indicate that there is an underlying indivisible, in other words holistic, dynamic whole. This means that we should use that as a point of departure and then describe the physical world,” says Barbara Piechocinska.

This is precisely what she has done. In her dissertation she proposes a philosophy that takes dynamics and wholeness as fundamental, instead of static parts that interact. Further, she suggests a mathematical description of this dynamics. Kinetic equations in classical Newtonian mechanics or in quantum theory make no distinction about whether time goes forward or backward. Dynamics, on the other hand, does, being based on wholeness. But Barbara Piechocinska can’t tell whether this is physically relevant or merely a mathematical construction.



“If this approach is elaborated further we will hopefully be able to answer that question. Because then we would see exactly what it predicts and could see whether the predictions square with reality. If it were to be shown that the extra bit is truly relevant in the physical world, then we would have good reason to reconsider our way of looking at the world and dethrone reductionism,” she says.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
