Hi guys, i initially created this for myself for my own research, but since i was told it's very good i decided to share it with the world. this will always be a free to use open source web app. you can just download the code itself and look at it with f12 there is no obfuscation. link will be in the comments.

Made an interactive simulation of the actual three-body problem in physics — three masses under mutual gravity, no simplifications. You can adjust masses and initial velocities and watch how small changes send the system from a stable-looking orbit into full chaos.

It's built to feel more like a physics toy than an app — no ads breaking up the simulation, nothing to unlock. Mostly wanted an excuse to actually play with the equations rather than just read about them.

Free on Google Play if anyone wants to mess with it: https://play.google.com/store/apps/details?id=com.mathematicalzen.threebody

I've been working on Hoops GM for so long, and now it has been a week since the launch.

I received a lot of backlash in the previous post due to an IP lawsuit, as well as a lot of praise from people.

The launch has been a MASSIVE success with now over 5000 visits to the game and an average of 50 new members everyday.

now i am very confident that this project will go very far and i am very happy about it!

THANK YOU to everyone who has checked it out, left a comment, or played a season.

(RE-WRITTEN BY HAND)
Keeping this to a short post, as I've already messed this up once. I built a simple aquarium-style concept, during a slow period on-shift, based on my Elementary School Memory of an Ecological Balancing Concept, involving Wolves, Deer, and Berry Bushes, as Entities in a Forest, where each Student played a Role.

I don't remember much past wishing we spent more time exploring it in-class, and that my teacher didn't so quickly drive it to an unrecoverable state, to make the point he was trying to teach that day.

It started in Google AI Studio, as a Boxed-Step-By-Step process, more resembling the Conway's Game of Life, in some ways. But it wasn't what I was aiming for. So, that evening, I sat with Devin, and Claude, and a Game Engine in TS/Lua/YAML that I've been working on Demos within, and refined it into something more like a living Reef.

After some insights from a smaller audience, I refined it with a Main Menu, and some Basic Selections.
It has Sharks, Fish, and Algae Nodes, and the Sharks eat/bite the fish, causing Meat Chunks to appear.
The Meat Chunks can then decay, turning back into an Algae Core Node.
If an Algae Core Node is left without children for long enough, it can despawn.

Last I checked, it has a fair chance of staying in balance for up to 10 minutes, but it needs further refinement.
There are also depth layers now, and in theory, the Sharks prefer the Deeper Waters, and the Fish stay toward the Sun, so the Sharks tend to bury their head at the bottom to warm back up, but sometimes starve.

Hi everyone,

I'm a university student and I'm currently working on a seminar paper for a course called Work Process Simulation. I need to use Arena Simulation to model and analyze a manufacturing/production process.

Unfortunately, I'm currently overwhelmed with other courses and exams, and I don't have enough time to properly learn Arena from scratch and build a complete project myself.

If anyone has an Arena project (.doe file) involving a manufacturing or production process that they would be willing to share with me, I would really appreciate it. I mainly need it as a basis for my seminar, so I can study the model, understand how it works, and perform my own analysis and write-up.

It doesn't have to be a perfect or complicated project — even a relatively simple production process would be extremely helpful.

I would be very grateful if someone could help me out. Thank you in advance!

P. S. it will not be published anywhere or used for anything else than paasing this course.

I saw a post where AI said the Anunnaki were evil. Just like people, there’s some good & some bad. There are many species from deep in the universe, and I feel like some of them look kind of creepy in human skin. They are walking around- All different kinds- I think many of them came to see the return of Jesus- The whole cosmos has been waiting-

Hi! I wanted to share my Android app that produces sound, real time, from string vibrations. The strings are simulated as coupled harmonic oscillators (solved through velocity-Verlet), and can be made and played by the user. In order to achieve real time 16-bit sound, I had to have the simulation update 48000 times per second, a speed which I could only achieve using C/C++ as a programming language, in the Raylib engine. I also included a spectrum through FFT, to see which frequencies are dominant. I thought this could be interesting for simulation and physics enthousiasts, as well as musicians. Enjoy it free and without ads!

Still kind of processing this as we didn't expect anything like this, but my brother and I just had our game, Federal Reserve Simulator, featured on NPR's Marketplace with Kai Ryssdal.

We’re just a two-person team, so hearing an 8-minute segment (titled "Running the Fed isn't easy, we tried it") dedicated to something we built from scratch was completely surreal. We launched back in February, and it's been a grind getting eyes on it, so this was a massive milestone for us.

You can hear the segment here:

I’m developing a web-based simulation called "Symbiocracy" to test a novel dual-system constitutional theory using "I cut, you choose" mechanics.

Current Status: The UI and the basic turn-based game loop are fully built. However, the underlying math and economic calculations are completely wrong right now (they are just placeholders). Overhauling the numerical model is my next major step.

What I'm looking for: If you can look past the broken numbers, I’d love for you to try the flow and give feedback on the core mechanics and the underlying theory. Is the incentive structure (budget negotiation + forced role-swap penalty) interesting or viable?

Future Roadmap:

• Adding diverse voter traits (currently they only care about GDP; I want to introduce specific policy preferences).
• Introducing random historical events and specific political issues.
• The ultimate goal: Integrating AI agents to simulate both the voters and the two political parties for automated Agent-Based Modeling.

Would love to hear your thoughts on the system architecture!

okay so ive narrowed it down to these two after reading like a million threads. the logitech is cheaper and seems reliable but everyone says gear driven wheels feel notchy whatever that means. the moza r5 is direct drive which apparently is way better but its also more expensive and im not sure if its worth it for someone whos never done sim racing before. from what i can tell the moza has better force feedback but the logitech works with playstation which i might use sometimes. has anyone actually used both and can tell me if the difference is really that noticeable. im at Gamer Gear Direct showroom next week to try some stuff but wanted opinions first

Hey , I am a highschooler , wants to learn more about simulations and all these stuff and want to create my own "world" (simulating some real things in my pc) . I know a lot of maths and physics (dont worry about it) , i want to learn more k have learnt some little computational methods for my physics engine and had created one , also some basic genetic algo projects (not impressive just some basic ones) and want to learn more deeper and more specialised projects like some astrophysics simulation (dont worry i know a lot of astrophysics too.. (i am too confident about it because i am national topper in physics and astro olympiad in highschool level (in india its very competitive and too hard to get into top 50 ))

just tell me books and resource , a sequence to follow (but i think they are all not much interconnected and can be started from any topic ) , i have read only

nature of code (coding train guy)

want to learn more and explore this

Hi I am currently doing an arena simulation assignment for my industrial engineering class. i was running into some issues with the software is which i am unsure how to add a final assign that included my calculations and how to calculate my final net profit. i was wondering if there was anyone here who could help me if i showed them the doe file.

Practical Explanation ( For Example ) :- `1st of all can you tell me every single seconds detail from that time when you born ?? ( i need every seconds detail ?? that what- what you have thought and done on every single second )

can you tell me every single detail of your `1 cheapest Minute Or your whole hour, day, week, month, year or your whole life ??

if you are not able to tell me about this life then what proof do you have that you didn't forget your past ? and that you will not forget this present life in the future ?

that is Fact that Supreme Lord Krishna exists but we posses no such intelligence to understand him.

there is also next life. and i already proved you that no scientist, no politician, no so-called intelligent man in this world is able to understand this Truth. cuz they are imagining. and you cannot imagine what is god, who is god, what is after life etc.

_______

for example :Your father existed before your birth. you cannot say that before your birth your father don,t exists.

So you have to ask from mother, "Who is my father?" And if she says, "This gentleman is your father," then it is all right. It is easy.

Otherwise, if you makes research, "Who is my father?" go on searching for life; you'll never find your father.

( now maybe...maybe you will say that i will search my father from D.N.A, or i will prove it by photo's, or many other thing's which i will get from my mother and prove it that who is my Real father.{ So you have to believe the authority. who is that authority ? she is your mother. you cannot claim of any photo's, D.N.A or many other things without authority ( or ur mother ).

if you will show D.N.A, photo's, and many other proofs from other women then your mother. then what is use of those proofs ??} )

same you have to follow real authority. "Whatever You have spoken, I accept it," Then there is no difficulty. And You are accepted by Devala, Narada, Vyasa, and You are speaking Yourself, and later on, all the acaryas have accepted. Then I'll follow.

I'll have to follow great personalities. The same reason mother says, this gentleman is my father. That's all. Finish business. Where is the necessity of making research? All authorities accept Krsna, the Supreme Personality of Godhead. You accept it; then your searching after God is finished.

Why should you waste your time?

_______

all that is you need is to hear from authority ( same like mother ). and i heard this truth from authority " Srila Prabhupada " he is my spiritual master.

im not talking these all things from my own.

___________

in this world no `1 can be Peace full. this is all along Fact.

cuz we all are suffering in this world 4 Problems which are Disease, Old age, Death, and Birth after Birth.

tell me are you really happy ?? you can,t be happy if you will ignore these 4 main problem. then still you will be Forced by Nature.

___________________

if you really want to be happy then follow these 6 Things which are No illicit s.ex, No g.ambling, No d.rugs ( No tea & coffee ), No meat-eating ( No onion & garlic's )

5th thing is whatever you eat `1st offer it to Supreme Lord Krishna. ( if you know it what is Guru parama-para then offer them food not direct Supreme Lord Krishna )

and 6th " Main Thing " is you have to Chant " hare krishna hare krishna krishna krishna hare hare hare rama hare rama rama rama hare hare ".

_______________________________

If your not able to follow these 4 things no illicit s.ex, no g.ambling, no d.rugs, no meat-eating then don,t worry but chanting of this holy name ( Hare Krishna Maha-Mantra ) is very-very and very important.

Chant " hare krishna hare krishna krishna krishna hare hare hare rama hare rama rama rama hare hare " and be happy.

if you still don,t believe on me then chant any other name for 5 Min's and chant this holy name for 5 Min's and you will see effect. i promise you it works And chanting at least 16 rounds ( each round of 108 beads ) of the Hare Krishna maha-mantra daily.

____________

Here is no Question of Holy Books quotes, Personal Experiences, Faith or Belief. i accept that Sometimes Faith is also Blind. Here is already Practical explanation which already proved that every`1 else in this world is nothing more then Busy Foolish and totally idiot.

_________________________

Source(s):

every `1 is already Blind in this world and if you will follow another Blind then you both will fall in hole. so try to follow that person who have Spiritual Eyes who can Guide you on Actual Right Path. ( my Authority & Guide is my Spiritual Master " Srila Prabhupada " )

if you want to see Actual Purpose of human life then see this link : ( triple w ( d . o . t ) asitis ( d . o . t ) c . o . m {Bookmark it })

read it complete. ( i promise only readers of this book that they { he/she } will get every single answer which they want to know about why im in this material world, who im, what will happen after this life, what is best thing which will make Human Life Perfect, and what is perfection of Human Life. ) purpose of human life is not to live like animal cuz every`1 at present time doing 4 thing which are sleeping, eating, s.ex & fear. purpose of human life is to become freed from Birth after birth, Old Age, Disease, and Death.
