If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread.

Essay Abstract

In this short one-page essay it is argued that mathematical structures used to describe physics are always nothing more than models prepared in abstraction of the reality, i.e. invented by humans, inspired by Nature and effective by design.

Author Bio

The Author got his PhD in 1991 from the University of Silesia, Poland. He is appointed since 2003 as Senior Lecturer at the Department of Theoretical Chemistry the same Alma Mater, and works also closely with the Computer Science Group at the Faculty of Mathematics, Physics and Chemistry.

Dear Dr. Wlodarz:

Your essay is very concise and very clear. Mathematical models work because they are designed to do so.

I agree, and my own essay, "Remove the Blinders: How Mathematics Distorted the Development of Quantum Theory", focuses on a particularly egregious example of how an incorrect mathematical model became accepted as reality, despite obvious "paradoxes". I argue that contrary to universal belief, a simple realistic picture of the microworld is possible, completely avoiding the paradoxes that plague orthodox quantum mechanics (including entanglement). QM is not a universal theory of matter; it is rather a mechanism for distributed vector fields to self-organize into spin-quantized coherent domains similar to solitons. This requires nonlinear mathematics that is not present in the standard Hilbert-space formalism. This also makes directly testable experimental predictions, based on little more than Stern-Gerlach measurements. Remarkably, these simple experiments have never been done.

So while mathematics can provide important insights into physics, an incorrect mathematical model that becomes established may be seen as virtually religious dogma which is not to be questioned. That prevents further progress.

Dear Joachim,

I think Newton was wrong about abstract gravity; Einstein was wrong about abstract space/time, and Hawking was wrong about the explosive capability of NOTHING.

All I ask is that you give my essay WHY THE REAL UNIVERSE IS NOT MATHEMATICAL a fair reading and that you allow me to answer any objections you may leave in my comment box about it.
