N-Body Simulations in Python

N-Body Simulations

Simulation of a dynamical system of particles, usually under the influence of physical forces using Python

The following document by Azal Amer details the steps required to create an n-body simulation with many particles. Specific to this simulation is the massless properties of the particles. A project like this would be very useful to create in an educational setting, both due to the experience of design, along with conceptualizing what it represents. This project could enable a more tangible understanding of vector math, along with designing basic algorithms. Learning to work with non-discrete time intervals for Physics simulations became a valuable skill derived from the project, one of whose techniques is described in this paper.

Azal Amer is a high school diploma student in Computer Science at Greenhill School and has completed an internship with ArtSciLab.

The watering Hole moves to the Desert O.A.S.E.S

O.A.S.E.S : Our Art Science Experimental Seminars.  

Over the years, the watering Hole has taken  several forms and  extensions.  However, core to all Watering Hole formats has been the propagation of the 3C’s :

  • Conversation,
  • Collaboration and
  • Creation.

Traditionally, the seminar has consisted of participants in a room full of snacks, a white board , projector, and 2-4 guest speakers per session. In these sessions there were introductions, presentations, discussions where odd connections were made between each presented topic, and feedback from participants.

The first extension of watering hole has been the Salon. Inspired by the Salons in Italy and France in the 1700-1800, the salon would be where the watering hole migrated to get even more casual- as in intellectual conversations, social connections,  wine glasses and home cooked tapas- type casual.  

During the later days of the Pandemic, the watering Hole took on the poetic style. In attempts to fuse  the classic Open Mic poetry and music scene, with the old school Watering hole seminar; the Virtual Watering Hole Open Mic was born.  Sometimes it took form of a writing workshop or a poetic analysis session, and other times it was more of a freestyle conversation with no designated guest speaker. During this period, the session held 4-6 people each time.

Finally the Watering Hole shifted to a Hybrid format with some participants on the screen and others physically present in the lab. With this hybrid twist, the Watering Hole reverted back to its initial format of guest speaker presentation and discussion. The only difference being it held mostly one guest speaker per session.

It was recently, in the Post Pandemic ArtSci Lab, that Roger Malina, The lab director and Mahmoud Elkarmalawy the lab coordinator come up with the brilliant new name for the Watering Hole – O.A.S.E.S . This new seminar identity officially opens the door to the endless possibilities of experimenting with the seminar and our collective gathering of consciousness. 

Who can design and experimental seminar? Well . Anyone, any group of ones or everyone together. That’s the whole idea of collaborating and involving our collective intelligence.

There are some things that would be important to keep in mind in future experimental seminars. One this is the types of moderation and experimenting with moderator roles and purposes during the session. Another is the potential for collecting valuable research data, and designing purposeful experiments keeping in minding International Regulatory Board procedures . Furthermore is the necessity to have all participants  sign release forms, and finding a reliable means to distribute these forms as is necessary for any publication of content recorded during the O.A.S.E.S sessions.

All in all, the future is looking bright, ‘well dated‘ and refreshing for the  O.A.S.E.S.  

And just another fun fact for our new Identity: If the watering Hole was where animals drank peacefully, the OASES is where the warring desert tribes had to drop down their weapons and enter into a peace zone as narrated in the story ‘The Alchemist ’ by Paolo Coelho. Perhaps at this new oasis, all our trained and isolated minds will evolve in collaboration and in the harmonious expression of ourselves.

Upcoming at the O.A.S.E.S

  • July 8th: Emeka Ikebude and Ayen Kuol
  • July 15th :Jacob Hunwick: Maintanence, repair and the illusion of Infinite growth
  • July 22nd: Karen Doore 

Recreating technology: The Light Guitar and The Art of Elen Nas

A guitar that makes music but not sound. Now that’s something to wrap your brain about.  Dr. Russel Stoneback, who conceptualized the idea of light guitar brought it to life in his graduate studies, and explains to us  the physics behind it . Through Russel’s narrative, we witness  how the pursuit of his musical passion led to the creation of  the ‘light guitar’ and to discover its existence in the grander universe

Similar to the sound wavelengths that are emitted when you blow over a bottle opening, the light guitar works by making electrons generate the same wavelengths as those generated when a guitar makes music in a similar fashion.  All you need is a hole/aperture, an accompanying conductive sphere, and and an electromagnetic field. The structure of the light guitar  happens to repeat itself in different systems of the universe: Light guitar physics is seen in the system between earth, its magnetic-fields and the opening at the aurora and   in the holes in the sun’s corona and coronal sphere.Light guitar physics could also explain the consistent frequency ‘humm’ that is emitted from Perseus Cluster black hole.  

Word Cloud of the Watering Hole

It doesn’t end there. To make musical sense of the wavelength data emitted from the light guitar, Dr. Russel recreated the principles from data flow of apple’s garage band , and the line 6 pocket pod  guitar effects processor which eventually led to the creation of PYSAT- Python Satellite analysis tool kit – that functions as a simple , flexible and effective interface for analyzing any data set  

Dr Russell isn’t the only one who brought to our attention the recreation of technology in creative practice. Dr. Elen Nas, Brazillian based artist and newest member of the ArtSci lab gave us a refreshing introduction to her work. She has explored the definition of technology as her work transitioned through the use of various technological forms. “Technology is like any type of language that is tentative to translation and imagination and what we perceive” states Dr. Nas. In her art work, she used various forms of technology , from her opera trained vocal chords, to Raspberry pi’s and image generation software . She showed to us how she made innovative uses of her art form in interaction with people, and natural elements and environments around her .In her art, Dr. Nas has expressed her tenacity to challenged rigid ideas of what is defined as ‘good art’ . She describes her work as requiring collective intelligence and her accomplishments as a result of the ‘cultural capital’ she had by acknowledging the magnitude of shared knowledge and people involve in sharing as well as giving back to the shared spaces. We discussed the role of mirror Neurons in collective spaces and saw how mirror neuronal responses were sometimes effective and sometimes not in Dr. Nas’ art experiments. What are the factors that influence the responsiveness of our mirror Neurons within shared spaces?  Perhaps Dr. Nas work can inform how we ‘play’ and interact in here in our shared Watering Hole space..

Storytelling as Technology: A Poetic Conversation with Baba the Stroyteller

Thursday, June 17 2021 

‘’Eee Jaliya-aa. Alaleka Jaliyaja”. 

From each Muted screen view, we could see lips moving in response to the call of the song. It was a way for the Griot to gather the village people together. How far the people were, how many were coming – all this information could be gathered by the call back of the song by the people. It was our song that would now be imbedded in all our neural circuits- explained baba, reminding us of the power of storytelling and music. By the time the story had ended, none of the watering hole participants was in the same place they started at. Baba the story teller, had succesfully immersed us into an experience outside our daily realm and culture.  

We must learn to immerse ourselves in different ways of life, in order to understand each other.  

In the audience, a question is raised: What is your role in counteracting the history that campaigns against stories of us as Africans?  

Baba’s response- ‘I touch hearts’.  

Word Cloud of the Watering Hole

Baba has been invited to exclusive spaces that the average person would not have access to ; spaces where he may change the perspectives and ideas of an influential person. A role not far from what the Griot played as advisor to kings. On surface level, Baba is invited to spaces as an entertainer, but here at the watering Hole, we straight up mean business. We mean conversation and ideas that will change how we navigate our world. Perhaps this is our idea of what entertainment means.  

Conversation Sentiment for Watering Hole’

Catch the conversation of us at the Watering Hole, Thursdays at 4-6PM

Guest Speaker : 

Baba the Storyteller has been a professional speaker since 1994 and is one of the few recognized U.S. born practitioners of the ancient West African storytelling craft known as Jaliyaa. He has received numerous awards over the years for his work as a folklorist, traditional harpist, storyteller, community activist and volunteer.  

Baba has presented in thousands of schools and other institutions all across the world. He is also a recipient of a California State Assembly Certificate of Recognition for his creative uses of storytelling and his commitment to community in working with troubled teens. The City of Long Beach California recognized Baba as their municipality’s Artist of the Year, an award presented to him by the Mayor. He has also earned additional commendations from both the U.S. Senate and U.S. Congress. Recently, 2017, Baba was recognized for his undying commitment to building community and activism by being presented the prestigious Heritage Award by the Aquarium of the Pacific during their Annual African-American Heritage Month Celebrations. 

Baba is currently touring internationally and working as a Master Teaching Artist with the Segerstrom Center for the Arts, designing curricula which fuse the arts with classroom instruction.

Lineage is not Linear: A Poetic conversation with Natachi Mez

I am standing face to face with the family tree, It asks me , don’t you know where you come from?  

I nod my head .  

Marvel at how seeds scatter.  

Any soil that catches you mothers you somehow.  

So many curriculums attempt  to Alienate us from ourselves , but contrary to popular belief, believe that we are all complete beings   

That double consciousness is an out of body experience. That we are learning how to return to body.  

Heaven embodied, none of us are property, none ….. can’t even fathom our infinity  

… In the mind I witness space expand. Sometimes a poem is birthing itself between breaths and I am watching conception.  

Everything I am , has been given to me, to transform.  I am fruit which means I am also seed. Everywhere I go I plant myself 

Listen We are  not scatted .  

Listen , everywhere we go we are planted  


Lineage is not Linear  

Everywhere we go  

Everywhere we go  

Everywhere we go ,  We call this earth our Home. ’’

An extract from ‘lineage is not linear’ by Natachi Mez

Who we are is a question that can be answered on many levels. But for many it is a question whose progression is blocked by the scars that formed when an entire people and cultural heritage were ‘plucked’ out and displaced. A culture and people who must overcome the  systems  in place to counter their Value &identity and find routes to thrive.  

At the watering Hole, Natachi Mez weaved an intricate fabric of imagery using the art of Spoken Word, and with it she clothed our experiences with a  magnificent perspective of who we are and the legacies  that hold us, despite adversity.  

During the session, her poem triggered the birth of a new poetic creation ,’A response to ‘lineage is not Linear by Roger Malina. Propagating creativity is exactly the kind of response we aim to see at the Watering Hole.

Join the conversation of us in dissecting a whole new expression of who we are and  what it means to migrate, to be a nomad , and to settle in ways that are far from linear.

Embracing Random at the Watering Hole

Friday, April 23 2021 


  • Ayen Kuol
  • Linda Anderson
  • Chukuwemeka Ikebude
  • Roger Malina
  • Chandra

With a rescheduling of our guest speaker and  a ‘vacant’ Watering Hole session coming up; the ArtSci Lab Watering Hole decided to take the turn of ‘chance’ into their own hands and what better way to do that than to embrace chance.  

It was Linda Anderson who started by introducing the concept of using ‘chance’ in creation of Art . 

We proceeded with our own collective experiment of creating a chance art piece with words as our medium. For ten uninterrupted minutes, the four participants of the watering Hole that day took turns to spit out lines of verse off the top of their heads to create a Random Poetic Piece.  

Our conversation found itself at the chance or ‘un’-chance of the  creation of the universe, the illusion of knowledge held by humans and the necessity of balance between chance and control, in creativity.  

A Poem of Chance

By the April 23rd Participants of the Watering Hole

Linda : Random art is fun 

Ayen: The scent from an old bottle lingers in the air  

Emeka: That sounds pretty much like the color of the rusting Gold

E: Silence especially from Roger and Chandra is the depth of knowledge 

R: Should we give plants the chance to vote 

C: All I can smell are spores

L: And I have a leak in my ceiling now which will turn into mold and spores 

A: They bring life to earth, they give trees a vote, they make the color of rusting gold smell like the color of dust and old. 

E: The Color of rusting gold is already taken,  you can’t find it on Go Daddy.  

R: Go daddy, I’m No body’s daddy. I’m now their friend.  

C: Unfurl the mommy  

L: Ok mum so whats for dinner’ 

A: When time goes by chance is all you have  

R: Chandra, chsandra chancedra 

E: I think it’s my turn; and it’s my turn to ask a question .Did you say roger, thst you are not a father; I know three of your offsprings 

R; But They have now become my friends, and they are no longer my children.  

L: Ohh that’S a difficult situation  

R: No it’s wonderful- They give me advice.  

R:Which my kids never did  

L: Oh I do, yeah mum do this .

R: Why is none of us wearing blue today.  

C: The sky is blue I can’t see a setting sun.  

A: What were moments in your life that were turning points of chance?  

R: *Gurgly sound effect* that’s what you sounded like  

E: Whats your full name again that’s an example of chance you might wana take note of that.  

R:And put it in your thesis 

E: Because no one expected that act  

R: This is getting painful- can we pull the plug off the tooth  

A: No we cannot, we must go on until the end 

L: Chance is in the thesis as well as other elements. 

R; Lithium  

C: Californian 

E; Chance is me being visited by death last night; and he spared me because I did not have corona virus

L: The highway strip down cambpell has wild flowers of red and blue now  

R: Just before you get to Coit street interrupt us  

E: I see colors too but I don’t see purple red and blue ; I only see  only browns filled with wheels from the end of whips and I also see ashes,.. grey matters, Ashes ..ashes.. Ashes’ 

A:When all burns to the ground can you say chance saved your life? Are you here or are you there/ Do old man’s hats with flowers tucked on top take you down through memory lanes? A dance of life

A: porcupine spikes.  

L: Yes  

A: Manmade creatures in synthetic lands.. Metal boxes that take men out in speeds beyond imagination in flights through ground 

R: We need to write the equation A+B/C = N+O*T 

E: That is the problem with white men, they think they have the power to define how the world exists they have take claimed to everything that moves the world – they want to write the equation and they want to attain their name to everything that has ever existed on this planet/  

L: Maybe we should go back further in time 

R: From the beginning the first word was chance wasn’t it ?  

E: There was no white man in the beginning, so how could anybody have known 

R; We are not descended from monkeys, we are descended from plants and trees 

E: We are not descended from anything- that’s against the laws of nature  

R : Ahh we are ascended not descended. We are ascended from the plants 

L: Somebody beteween a neadathrals and homosapiens  

A; In the beginning we started by chance 10 mins late we find ourselves in chance. What was not meant to be .  

C: Im thinking about DNA.  

A Poetic Conversation on Dark Matter with Dr. Lindsay King

April 16th 2021

What is the first thing that comes to your mind when you meet that Phrase Dark Matter?  

Perhaps for a trained  physicist, a collection of calculations , models and experimental data  would come up – indicating to the idea of  the existence of dark matter  rather than its actual form. Generally, dark matter is called dark ,because it emits no electromagnetic radiation.  

On April 16th 2021 at the watering hole, Lindsay king, through the vehicle of poetic performance, took us  on a voyage from the center of our galaxy to its outer regions, transitioning between visible and dark matter being dominant, and into the large-scale cosmic web that forms the skeleton of the universe.

However, what do we discover about ourselves as we reflect on the concept of dark matter through the lens of our human lives?  
What consequences  does scientific terminology  influenced the way that we think?  

Catch the conversation of us with  Lindsay King , Ayen Kuol , Emeka Ikebude, Jacob Hunwick, Roger Malina, Chris , Lagu Stephen in the linked podcast.

Speaker Profile

Lindsay King grew up in Ireland, in a small town near Belfast. She specialized in physics at Cambridge and did her PhD work in astrophysics at Manchester. After postdoctoral work in the U.S. and Germany, she returned to Cambridge as a Royal Society university research fellow. She relocated to Dallas just over 9 years ago and is faculty in the physics dept. Her research program combines computational and theoretical astrophysics with analysis of real data. Projects include studying dark matter in clusters of galaxies (the most massive objects in the Universe) using computer simulations and real data. Other new theoretical work involves predicting Gravitational Wave signals from black holes that are gravitationally lensed by intervening objects, and assessing the impact of lensing on our understanding of black holes seen by current and future detectors. 

P. Antoinette White: My Experience with the ArtSciLab

I was with the ArtSciLab for a little under two years. During this time, I was able to collaborate on a number of different projects, aside from the main one I was hired for. This was a perfect representation of what the lab was based on: people with different backgrounds coming together to collaborate on any number of projects, with the intent of creating something. The lab sought to bring together all the various interests individuals may have, while seeking knowledge. Coincidentally, the main project I worked on was with Alex Garcia Topete, and it focused on the interdisciplinarity of research. I saw firsthand how useful it is to work alongside people who have a different background than I do: other lab members would give us ideas or perspectives that we did not have, and could help us with things we did not have experience with.

It was an environment of people seeking to learn and create. We would sometimes have debates about subjects that had nothing to do with what our projects were, and even though they could get heated it was all in good faith; as I said before, it was just a group of people getting together to search for knowledge.

I was also constantly asked if there was anything in particular that I was interested in that I would like to work on. I never was, but I know that if it had been the case my ideas would have been looked into and, if plausible, come to fruition. It was very obvious that the lab’s mentality was one of growth, and of helping others develop their ideas and, in turn, themselves.

I also got to practice working at my own pace, knowing when I had to turn something in and being solely responsible for getting it done. Organizational skills are key when working in research, and this will particularly carry over to my future employment: I am going on to work as a financial analyst, and I will have to organize myself in a way in which I can turn in my projects when they are due.

I am taking with me the sense of working as a team, which I know will be very important in any future employment. I will also take with me the feeling that I can express ideas and proposals freely, and the feeling that working as a team is usually better than working alone. 

Presenting Code of Ethics of the ArtSciLab

The ArtSciLab is one of the founding research groups of the Edith O’Donnell School of Arts and Technology in 2014. Its main task has been to bridge Art and Science alongside innovative technologies and research to help shape the future. The creation of the first official Code of Ethics (COD) in 2020 is long overdue. After a large global social shakeup that sprouted as the awakening of the Black Lives Matter movement in late May and early June, the creation of a COD was imminent. Our COD appeals for a more equitable, trustworthy and open work and study environment than ever before. 
The newly formed COD vocalizes the need for providing opportunities without discriminating during our processes of promotion, training and development of our members. An equal evaluation of ideas is what we strive for, as diversity and openness leads to creativity and innovation. 

Trusting and empowering those young researchers is essential, as well as having devoted mentors in the lab that guide other members. 
We aim to deal with not only conflict, but also opportunity with an open mind and transparency.Artists, designers, engineers, scientists and those that seldom fit in have a home in the ArtSciLab. This new ethical document seeks to serve our ArtSci community.
