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: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
