Scaling The Cosmos: Global Human Positioning Night Sky Laboratory

•January 29, 2021 • Leave a Comment

Scaling the Cosmos: Global Human Positioning Night Sky Laboratory, a spectacular public experiment across the skyline, visible from space, illuminating the landscape on planet earth. Scaling the Cosmos will inspire wonder in audiences across the Bay Area while uplifting under recognized contributions to science by women and championing the importance of scientific literacy.

To realize this project, we will point a laser from atop the Salesforce Tower toward Mt. Tamalpais (14 miles away stretching across the San Francisco Bay and two counties), recreating Armand Hippolyte Louis Fizeau’s historic 1849 experiment calculating and measuring the speed of light. The experiment will also honor astronomer Jocelyn Bell Burnell, who made one of the most important astrophysics discoveries of the 20th century: the radio pulsar. Spelletich will transmit simple Morse Code, audio (soundsand stories, poems), messages to other life forms/Extraterrestrial Intelligence and other codified data through laser light to communicate messages addressing our existence in the cosmos alongside observations from the public. We would conduct our Art & Science Light Projection Experiments for one month of Thursdays.

Sample messages include: Be Here Now; As is the Microcosm So is the Macrocosm; C = 3×108 (the speed of light). Scaling the Cosmos will be a remarkable public event that makes tangible the obscure measurement of light, placing control of this wondrous technology and powerful communication tool in the hands of the public.

Fizzeau’s historic 172 year old experiment eventually allowed us to use the speed of a light wave as the length standard to determine the scale of the cosmos. Using contemporary and original 1800’s technology from lasers, light sensors, and satellite positioning, we will recreate this historic experiment. This is big picture science and art looking at deep time and space.

Bell Burnell’s discovery, which she made as a graduate student, eventually earned the Nobel Prize in 1974. It could one day form the basis of a “galactic positioning system” for navigating outside our solar system. But Bell Burnell didn’t collect the Nobel. Instead, the award went to her supervisor at the University of Cambridge, Antony Hewish. She is now rightly recognized as the pioneer who made this breakthrough discovery and an inspiration to those addressing gender-bias in science.

Here is a prototype of the project. Scaling the Cosmos will be 63,360 time larger

The project is also inspired by Spelletich’s observations of the Eiffel Tower — how it was used, and eventually saved, because it became a locus for cutting edge scientific experiments and optical communication from fiber optics to Morse code. Scaling the Cosmos activates the newest addition to the San Francisco skyline, the Salesforce Tower, with a call for public science that echoes the Eiffel Tower experiments in Paris.

Scaling the Cosmos will span across two counties and be visible across the Bay Area, reaching millions of people. In the lineage of the Bay Lights, San Jose Semaphore, Pi in the Sky, and other large-scale public art projects originating from ZERO1 over the past twenty years, Scaling the Cosmos will be accessible to viewers across a large geographic area at no cost. The beam of light will inspire awe in viewers of all ages, inviting them to rediscover the wonder of science.

Imagery of two lasers reflected and playing off of each other

The online presence of the project will solicit input from audiences and guide their open-ended inquiry into the history of science. We will give a live feed as we measure the speed of light and measure the exact distance from sky scraper to mountain. The project website will also host a series of interdisciplinary talks by artists, scientists, and philosophers that will expand on the history of science and contemporary understandings of science and culture.

Scaling the Cosmos is part of a series of works by Spelletich that celebrate the scientific method and reference foundational scientific discoveries with an emphasis on marginalized scientists. Spelletich recreates historic gravity, light, and sound wave experiments that allowed us to understand the scope and scale of our planet, our solar system, to know our beginnings and our place among the stars and the expansive entirety of the cosmos. These recreations and interpretations celebrate the scientific method and reference foundational scientific discoveries. With them, Spelletich aspires to inspire social engagement, both inside the gallery and to the outside world. Spelletich’s creations carry us back in time, to when the sciences and the arts were one, to the fundamentals of how the universe works, how we observe the cosmos, and how we determine humanity’s place within it.

In the contemporary context of politicization and polarization around science, Spelletich is working to celebrate science through art. With the firm assertion that science is real, Spelletich confronts flat earthers, climate change deniers, anti-vaxxers, and a resurgent eugenics movement with an aesthetic invitation to join in the collective practice of understanding the world around us.

There is a long tradition of native people in the Great Basin use signal fires on major peaks to quickly transmit news across the basins (valleys).
During the great surveys of the 19th century of the Bay Area to Nevada (some of the same peaks used by native Americans), from which to project light with mirrors to triangulate parallels of latitude). John Muir and Kit Carson guided Frémont during the first exploration of the Sierra Nevada range in California. (They were advised by Native people, as well).

Jocelyn Burnell is still alive.

Astronaut William Anders said that although the astronauts went on their mission to explore the moon, what they really discovered was the planet Earth. He added: “I think it’s important for people to understand they are just going around on one of the smaller grains of sand on one of the spiral arms of this kind of puny galaxy […] it [Earth] is insignificant, but it’s the only one we’ve got.”


July 1849: Fizeau publishes results of speed of light experiment

The speed of light is one of the most well-established values in physics, traveling at over 186,000 miles a second, can be measured so accurately that the meter is now defined in terms of it. But before the 17th century, most scientists, including such giants as Johannes Kepler and Rene Descartes, considered the speed of light to be infinite, able to travel any distance instantaneously. Galileo Galilei was among the first to question this assumption and attempt to measure the speed of light experimentally.

Zooming Out Scaling The Universe:

“If you wish to make an apple pie from scratch, you must first invent the universe.”

“The most beautiful thing we can experience is the mysterious. It is the source of all true art and science” – Albert Einstein

The experiential nature of the experience of deep time has also greatly influenced the work of Joanna Macy.

She is an international spokesperson for anti-nuclear causes, peace, justice, and environmentalism,[1] most renowned for her book Coming Back to Life: Practices to Reconnect Our Lives, Our World and the Great Turning initiative, which deals with the transformation from, as she terms it, an industrial growth society to what she considers to be a more sustainable civilization. She has created a theoretical framework for personal and social change, and a workshop methodology for its application. Her work addresses psychological and spiritual issues, Buddhist thought, and contemporary science. She currently lives in Berkeley, Ca.

Korten’s 2006 book The Great Turning: From Empire to Earth Community argues that the development of empires about 5,000 years ago initiated unequal distribution of power and social benefits to the small portion of the population that controlled them. He also argues that corporations are modern versions of empire, both being social organizations based on hierarchies, chauvinism, and domination through violence.

The Roman Catholic theologian Thomas Berry (1914–2009) explored spiritual implications of the concept of deep time. Berry proposes that a deep understanding of the history and functioning of the evolving universe is a necessary inspiration and guide for our own effective functioning as individuals and as a species.

How do we save what is left of the planet? How do we save humankind? The sciences and the arts are the key.

RC3 Hacker Conference workshop->

•December 25, 2020 • Leave a Comment

I am presenting at the RC3 Conference this rC3 – remote Chaos Experience
this SUNDAY December 27, at 1:30 Pacific Time 2020

This year, CCC hosts the Remote Chaos Experience (rC3) instead of an on-site event in Leipzig.
This endeavor requires creativity, joy of experimentation and active support.

Art, Science and Artistic Revolutionary Practices

An interactive workshop/demonstration of my art and machines that are about sound, science, absurd engineering,
interactivity and poetically inspired tech. I will talk a bit about my life as an artist and educator. Then
demonstrate a number of my works while fielding questions.

How to build low-cost tech art for next to nothing. Hack Arduino sensors by not using an Arduino!
Collaborate as often as possible, 3 people are a revolution and movement.
Advice on showing your weird tech art.
Why Art!? Because we can and are changing the world with it.
By finding your voice you become empowered and discover your reason for being on the planet! Once you do that,
there is no stopping you.

For almost 4 decades Kal Spelletich has built interactive machines and robots. Spelletich’s work enacts a
liberated awareness and pushes his audience toward creative responses to technology in their lives. His work
explores the interface of humans and science to put people in touch with philosophical interactive experiences.

A face-to-face event with 17,000 people will be neither responsible nor legally feasible this year. But after
this tedious and painful 2020, we really deserve a nice finale!
This is why the rC3 – Remote Chaos Experience will be held.
As much as virtually possible, we want to convey the joy, content, togetherness and wonderful madness that
make up a Chaos Communication Congress.

Hackers are used to remote work and online meetings. This makes our annual face-to-face meetings all the
more important. Of course, it will be difficult to re-enact online
all the things that make Congress what it is for us.
But then someone said it would be impossible. Our ambition was aroused.
Just like every year, we want to see the concentrated energy and creativity of hackers with dedication.

Pre-requisites: None
Preparation and supplies: None, but here is where I get my materials.

The New REcord is OUT!

•November 21, 2020 • Leave a Comment

My Album is out!!!
Get it here:

I am excited to try this as an experiment for MY RECORD RELEASE PARTY. Everyone is invited. Those that purchase ahead of time are invited to join in for an improv noise sesh we are going to record livestream event and release, date in the next couple of weeks TBA.


“All of the sounds heard on this recording are from custom made machine/robot instruments. None of the sounds on this recording come from store bought instruments, samples, albums nor field recordings. The sounds come from sound machines I made. Let’s just call me a purist.

I often felt like I was coaxing my motorcycle to talk. Or training a puppy.
This work can be utilized in many ways…. for instance put it on and do your housework. Vacuuming the floor or grinding coffee allows you to perform and collaborate with me!

These are compositions not so much songs. They are arranged sounds.”
— Kal Spelletich, 2020

I recorded several albums in the 1980’s in Austin and in the early ’90’s here in SF. I have waited long enough to start back with this body of work..

And oh, the ZHENGKE ZGA37RG is a motor I very frequently use these days, it is truly a blessing!

What Spelletich has done here is like making compositions with your blender, a dripping faucet and a chorus of mewing kittehs.
Truly a monument to ingenuity and madness meets FINDING poetry in a factory of chaos.
We are lucky to have a record label on the planet with the foresight to acknowledge the exceptionally unique.
-Luigi Carlo Filippo Russolo

Inspired by this poster by El Lissitzky .

Susan Spelletich was a civil rights lawyer. She started in Legal Services for Children, having worked with children in special education. Susan eventually ran a department in the U.S. Department of Education with the Civil Rights division ensuring equal access to education through vigorous enforcement of civil rights laws. She helped shape California education rights for children, which trickled up to shape national laws affecting millions of students. She prosecuted educational institutions that discriminated against someone on the basis of race, color, national origin, sex, disability, or age. She also worked on one of the first cases related to a college’s inadequate response to reports of sexual harassment. She could have easily made a tenfold salary working in private law but she eschewed that for the well being of humankind.

Nevavda Exhibit Small(1)

I cordially invite you to the closing event on Saturday 2/15 12:00-2:00, for my exhibit of ‘Strawberry Creek and Science Obscured’ at The Catharine Clark Gallery. Chester Arnold and I will be in conversation with Catharine Clark about the environment, our work in the exhibit and our upcoming collaboration.
Chester and I plan to create an homage to the Napa River that reveals different views of this waterway that has survived the wrath of channelization, bulldozing and reshaping of it’s flow. We will create a new site specific installation that incorporates one of Chester’s paintings, along with video, sound, and robots in the manner of Strawberry Creek which is in The Catharine Clark media room now until February 15th. Nature prevails!
Then we party!

Science Obscured, on display in The Catharine Clark back room, is a series of individual laser carved paper images that subtly unveil the monumental contributions of dismissed scientists. Next to these a robotic sculpture meditates on waves: light waves create sound waves create gravity waves, all activated by light, like from the flashlight on your phone. See ‘Descartes’ Laws of Motion’ in action: https://youtu.be/By7dRZGnYv0
‘Waves’ is a black on black carved paper image in an edition of 15. There are only a handful of these left!
Inquire at the gallery or ask me or see the attached image (more on this work at the very bottom of this email).

Saturday, February 15, 2020 At 12:00-2:00 P.M.
The conversation commences at 1:00 sharp!

Laser Carved Paper Edition ‘Waves’ at The Catharine Clark Gallery

Here is a work on paper I have in the exhibit. It is laser carved paper in a series of 15. No two are alike. They are priced at $350.00 each! The other works on paper are one of a kind and priced quite a bit more. The image represents two sets of waves. As they travel out they can reinforce each other to create a larger wave or do the opposite and cancel each other out. A wave can be liquid, sound, light, gravity or even a thought. This is how change happens. Oftentimes it may take eons for that change.

Every action has a reaction.

Sea and ocean waves are caused due to gravitational energy of moon. If we harness them, we are indirectly harnessing the energy obtained due to moon’s mass.

Waves are described by a wave equation which sets out how the disturbance proceeds over time. The mathematical form of this equation varies depending on the type of wave. Further, the behavior of particles in quantum mechanics are described by waves. In addition, gravitational waves also travel through space, which are a result of a vibration or movement in gravitational fields.

This wave can then be described by the two-dimensional functions
(waveform traveling to the right)
(waveform traveling to the left)
or, more generally, by d’Alembert’s formula:[3]

Here we are representing two component waveforms and traveling through the medium in opposite directions. A generalized representation of this wave can be obtained[4] as the partial differential equation
Waves; sound, light and physical waves. Water waves and sound waves are examples of mechanical waves. Light waves are not considered mechanical waves because they don’t involve the motion of matter. Light waves are just one type of electromagnetic wave. Sound waves exist as variations of pressure in a medium such as air. They are created by the vibration of an object, which causes the air surrounding it to vibrate. … Sound waves travel through air in much the same way as water waves travel through water.
Light, sound, energy, water waves, ripples, (wave interference)
Nothing that contains energy is “outside of time.” The reason is that the energy of any object is linked, by quantum physics, to the rate of oscillation of its wave function. Thus, if you have energy E (including any rest energy mc2), then your quantum wave function is oscillating with frequency f=E/h where h is Planck’s constant. So if you exist (and I take that to mean that you have some non-zero energy) then you vary in time.

Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum.
Light waves are different from mechanical waves, however, because they can travel through a vacuum. Light waves are just one type of electromagnetic wave. Other electromagnetic waves include the microwaves in your oven, radio waves, and X-rays.

In fact, there are two main types of waves: transverse and longitudinal. Longitudinal waves are where the vibration moves parallel to the direction the wave is traveling. Sound vibrations travel in a wave pattern, and we call these vibrations sound waves. Sound waves move by vibrating objects and these objects vibrate other surrounding objects, carrying the sound along. … Sound can move through the air, water, or solids, as long as there are particles to bounce off of.

“Light was not either a wave or a particle but was both a wave and a particle. Knowledge of both these very different aspects was necessary for a complete description of light; either one without the other was inadequate.”
– Niels Bohr
