Here’s more about Quantum Rhapsodies, a free public art/science music performance at the University of Illinois on April 10, 2019, from an April 5, 2019 University of Illinois news release (also here) by Jodi Heckel,

A new performance that explores the world of quantum physics will feature the music of the Jupiter String Quartet, a fire juggler and a fantastical “Alice in Quantumland” scene.

“Quantum Rhapsodies,” the vision of physics professor Smitha Vishveshwara, looks at the foundational developments in quantum physics, the role it plays in our world and in technology such as the MRI, and the quantum mysteries that remain unanswered.

“The quantum world is a world that inspires awe, but it’s also who we are and what we are made of,” said Vishveshwara, who wrote the piece and guided the visuals.

The performance will premiere April 10 [2019] as part of the 30th anniversary celebration of the Beckman Institute for Advanced Science and Technology. The event begins with a 5 p.m. reception, followed by the performance at 6 p.m. and a meet-and-greet with the show’s creators at 7 p.m. The performance will be in the atrium of the Beckman Institute, 405 N. Mathews Ave., Urbana, [emphases mine] and it is free and open to the public. While the available seating is filling up, the atrium space will allow for an immersive experience in spite of potentially restricted viewing.

The production is a sister piece to “Quantum Voyages,” a performance created in 2018 by Vishveshwara and theatre professor Latrelle Bright to illustrate the basic concepts of quantum physics. It was performed at a quantum physics conference celebrating Nobel Prize-winning physicist Anthony Leggett’s 80th birthday in 2018.

While “Quantum Voyages” was a live theater piece, “Quantum Rhapsodies” combines narration by Bright, video images and live music from the Jupiter String Quartet. It ponders the wonder of the cosmos, the nature of light and matter, and the revolutionary ideas of quantum physics. A central part of the narrative involves the theory of Nobel Prize-winning French physicist Louis de Broglie that matter, like light, can behave as a wave.

The visuals – a blend of still images, video and animation – were created by a team consisting of the Beckman Visualization Laboratory; Steven Drake, a video producer at Beckman; filmmaker Nic Morse of Protagonist Pizza Productions; and members of a class Vishveshwara teaches, Where the Arts Meet Physics.

The biggest challenge in illustrating the ideas in the script was conveying the scope of the piece, from the galactic scale of the cosmos to the subatomic scale of the quantum world, Drake said. The concepts of quantum physics “are not something you can see. It’s theoretical or so small you can’t put it under a microscope or go out into the real world and film it,” he said.

Much of the work involved finding images, both scientific and artistic, that would help illustrate the concepts of the piece and complement the poetic language that Vishveshwara used, as well as the music.

Students and teaching assistant Danielle Markovich from Vishveshwara’s class contributed scientific images and original paintings. Drake used satellite images from the Hubble Space Telescope and other satellites, as well as animation created by the National Center for Supercomputing Applications in its work with NASA, for portions of the script talking about the cosmos. The Visualization Laboratory provided novel scientific visualizations.

“What we’re good at doing and have done for years is taking research content and theories and visualizing that information. We do that for a very wide variety of research and data. We’re good at coming up with images that represent these invisible worlds, like quantum physics,” said Travis Ross, the director of the lab.

Some ideas required conceptual images, such as footage by Morse of a fire juggler at Allerton Park to represent light and of hands moving to depict the rotational behavior of water-based hydrogen within a person in an MRI machine.

Motion was incorporated into a painting of a lake to show water rippling and light flickering across it to illustrate light waves. In the “Alice in Quantumland” sequence, a Mad Hatter’s tea party filmed at the Illini Union was blended with cartoonlike animated elements into the fantasy sequence by Jose Vazquez, an illustrator and concept artist who works in the Visualization Lab.

“Our main objective is making sure we’re representing it in a believable way that’s also fun and engaging,” Ross said. “We’ve never done anything quite like this. It’s pretty unique.”

In addition to performing the score, members of the Jupiter String Quartet were the musical directors, creating the musical narrative to mesh with the script. The music includes contemplative compositions by Beethoven to evoke the cosmos and playful modern compositions that summon images of the movements of particles and waves.

“I was working with such talented people and creative minds, and we had fun and came up with these seemingly absurd ideas. But then again, it’s like that with the quantum world as well,” Vishveshwara said.

“My hope is not necessarily for people to understand everything, but to infuse curiosity and to feel the grandness and the beauty that is part of who we are and the cosmos that we live in,” she said..

How to look at SciArt (also known as, art/science depending on your religion)

There’s an intriguing April 8, 2019 post on the Science Borealis blog by Katrina Vera Wong and Raymond Nakamura titled: How to look at (and appreciate) SciArt,


The recent #SciArt #TwitterStorm, in which participants tweeted their own sciart and retweeted that of others, illustrated the diversity of approaches to melding art and science. With all this work out there, what can we do, as advocates of art and science, to better appreciate sciart? We’d like to foster interest in, and engagement with, sciart so that its value goes beyond how much it costs or how many likes it gets.

An article by Kit Messham-Muir based on the work of art historian Erwin Panofsky outlines a three-step strategy for looking at art: Look. See. Think. Looking is observing what the elements are. Seeing draws meaning from it. Thinking links personal experience and accessible information to the piece at hand.

Looking and seeing is also part of the Visual Thinking Strategies (VTS) method originally developed for looking at art and subsequently applied to science and other subjects as a social, object-oriented learning process. It begins by asking, “What is going on here?”, followed by “What do you see that makes you think that?” This allows learners of different backgrounds to participate and encourages the pursuit of evidence to back up opinions.

Let’s see how these approaches might work on your own or in conversation. Take, for example, the following work by natural history illustrator Julius Csotonyi:

I hope some of our Vancouver-based (Canada) art critics get a look at some of this material. I read a review a few years ago and the critic seemed intimidated by the idea of looking at work that explicitly integrated and reflected on science. Since that time (Note: there aren’t that many art reviewers here), I have not seen another attempt by an art critic.

Capturing the particle and the wave: photographing light

On returning to school to get a bachelor’s degree, I registered in a communications course and my first paper was about science, light, and communication. The particle/wave situation still fascinates me (and I imagine many others).

A March 2, 2015 news item on phys.org describes the first successful photography of light as both particle and wave,

Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at EPFL [École polytechnique fédérale de Lausanne in Switzerland] have succeeded in capturing the first-ever snapshot of this dual behavior.

Quantum mechanics tells us that light can behave simultaneously as a particle or a wave. However, there has never been an experiment able to capture both natures of light at the same time; the closest we have come is seeing either wave or particle, but always at different times. Taking a radically different experimental approach, EPFL scientists have now been able to take the first ever snapshot of light behaving both as a wave and as a particle. The breakthrough work is published in Nature Communications.

A March 2, 2015 EPFL press release (also on EurekAlert), which originated the news item, describes the science and the research,

When UV light hits a metal surface, it causes an emission of electrons. Albert Einstein explained this “photoelectric” effect by proposing that light – thought to only be a wave – is also a stream of particles. Even though a variety of experiments have successfully observed both the particle- and wave-like behaviors of light, they have never been able to observe both at the same time.

A research team led by Fabrizio Carbone at EPFL has now carried out an experiment with a clever twist: using electrons to image light. The researchers have captured, for the first time ever, a single snapshot of light behaving simultaneously as both a wave and a stream of particles particle.

The experiment is set up like this: A pulse of laser light is fired at a tiny metallic nanowire. The laser adds energy to the charged particles in the nanowire, causing them to vibrate. Light travels along this tiny wire in two possible directions, like cars on a highway. When waves traveling in opposite directions meet each other they form a new wave that looks like it is standing in place. Here, this standing wave becomes the source of light for the experiment, radiating around the nanowire.

This is where the experiment’s trick comes in: The scientists shot a stream of electrons close to the nanowire, using them to image the standing wave of light. As the electrons interacted with the confined light on the nanowire, they either sped up or slowed down. Using the ultrafast microscope to image the position where this change in speed occurred, Carbone’s team could now visualize the standing wave, which acts as a fingerprint of the wave-nature of light.

While this phenomenon shows the wave-like nature of light, it simultaneously demonstrated its particle aspect as well. As the electrons pass close to the standing wave of light, they “hit” the light’s particles, the photons. As mentioned above, this affects their speed, making them move faster or slower. This change in speed appears as an exchange of energy “packets” (quanta) between electrons and photons. The very occurrence of these energy packets shows that the light on the nanowire behaves as a particle.

“This experiment demonstrates that, for the first time ever, we can film quantum mechanics – and its paradoxical nature – directly,” says Fabrizio Carbone. In addition, the importance of this pioneering work can extend beyond fundamental science and to future technologies. As Carbone explains: “Being able to image and control quantum phenomena at the nanometer scale like this opens up a new route towards quantum computing.”

This work represents a collaboration between the Laboratory for Ultrafast Microscopy and Electron Scattering of EPFL, the Department of Physics of Trinity College (US) and the Physical and Life Sciences Directorate of the Lawrence Livermore National Laboratory. The imaging was carried out EPFL’s ultrafast energy-filtered transmission electron microscope – one of the two in the world.

For anyone who prefers videos, the EPFL researchers have  prepared a brief description (loaded with some amusing images) of their work,
