Last evening I attended the most incredible lecture by Prof. Frank Wilczek from MIT. A Physics Nobel prize winner (2004), Prof. Wilczek has written a book: A Beautiful Question.
The lecture also titled, A Beautiful Question, explored the deep and fascinating connection between beauty and Science or our understanding of the world.
He asked: “Does the world embody beautiful ideas” and “Is the world a work of art”.
In exploring the answers to these questions, the tour took us through some very cool principles, not unknown to scientists and engineers. But in the context they seemed fresher and somehow their beauty became more apparent than before.
For example, symmetry. If we perform a transformation that leaves the content unchanged but changes the form. A circle might be rotated, an equation like x=y with the transformation y becomes x and x becomes y, remains unchanged in content : y=x , but changes in form. Effectively we are only changing perspective and in the new perspective the object might look different, but it’s reality is unchanged.
He showed us a slide of how colours of electromagnetic waves appear different in the relatavisitic Doppler effect. Red shifted when moving away, and blue when moving closer. This led me to ask: if the wavelenght/frequency of light is a matter of perspective, then what is the underlying content or intrinsic reality of an electromagnetic wave that doesn’t change?
He considered anamorphic art and how an image changing media is needed for this. As a parallel he considered general relativity where a metric fluid is needed for similar effect. See for example http://loudwigvanludens.weebly.com/anamorphic-works.html, something I found later. The parallels between art and science where beauty plays a part were a completely new way of expressing perhaps the loveliness many of us see in science.
There was some very persuasive examples that physics theories can be beautiful. Often theories that are beautiful may lead to deep insights with the caveat that one must always verify and not trust blindly to any theory no matter how beautiful. So as a proponent of the SUSY or super symmetry model which envisages a unification of all the forces that is the point he left us at.
I intend to read the book if only to see science from a romantic, aesthetic angle!
