Hi, I made a project that calculates the collatz conjecture, then graphs it out. I would really appreciate it if you checked it out!
There is also one on prime numbers, but no graphing is involved.
Also one on the fibbonacci sequence. Also no graph.

It would be awesome if one of these went in the studio.

Thanks!
Oh wow I hope all three of them get added by UnscrambledEgg!
Thank You so Much, the support means everything!

Please… Do NOT advertise something that is not related to STEM. Why do people these days just post comments on such areas where the main purpose is not verified for their projects?

Is it possible for rats to be button trained like dogs?(to some degree)
To be Honest, the size of the buttons should be acessible towards rats to be able to press it. Secondly, the specific rat should have the amount of IQ and interactive learning ability (just like machine learning and the dogs' learning) to be able to communicate to us through the buttons. To some extent, rats could possibly be trained using rat's understanding's training plus they should have an amount of efficient conciousness just like dogs. The rats might first interact with the buttons and learn what humans react to different phrases and sentences, then continue to live with limited amount of understanding of the human capability. Unfortunetly, I think there would be a very less amount of rats who may understand and learn like machine AI and their body size and brains wouldn't be that capable of just pressing random buttons probably for entertainment or so. In summary I'm trying to say that rats need enough brain capability to press random buttons and interact with human reactions for each, just like button-training dogs. I hope this is pretty mid language to explain in, Thank you.

Per say, is there any way to simulate gravity in a manner that it follows most or ALL of Newton's or Einstein's laws of mechanics related to celestial bodies and space? I am deciding to make a project stimulating gravity in fictional space, I hope anybody could help on the subject?

Look up some projects about it and get ideas. Physics simulators require a bit of coding and math though. I’d love to see the finished project.

Thanks for the idea! I might work on the project someday …

Guys see this:



when the laser pointer (only found in Algodoo (earlier Phun)) produces light, specifically white light, it goes through a medium of the triangle (2D intended prism), it comes out as beam of several clours. These colours are VIBGYOR or ROYGBIV (Red, Orange, Yellow, Green, Blue, Indigo and Violet, including many other visible in-betweenies like Aquamarine or a dark Magenta).
And as you guessed -
  • This scenario/phenomena also happens in real life, for example the glass of a “shaker” or our actual human eyes.
  • Actually this happens because white light is made up of several different beams of light fused into one joined bright white abomination of making us blind. LOL
  • Plus, we can see rainbows because there is this phenomena where the sun produces white light (sunlight) and the water droplets intend to “break” or extend the angle of reflection, thus the colors are revealed in chronological order of the visible spectrum.
  • keep in mind: the laser pointer and the glass triangle is EXACTLY 1m (one meter/metre) away from each other. Idk if you need this info but I suspect it is really needed.
BUT…



HERE… the laser pointer is pointing directly at corner of the triangle. Here the color spectrum splits into two diffrent groups. One group of the colour spectrum appears quite duller than the last spectrum of colours. On the other hand, the other group of the colour spectrum seems to have missing a few colours, especially, ROY (Red, Orange and Yellow) while showing the other half of the spectrum, which is VIBG or GBIV (Green, Blue, Indigo and Violet + the significant in-between, Aquamarine). With this, im trying to imply that -
  • This can only be one phenomenon, UV rays… (audience's loud gasp )
  • In this phenomenon, we can visibly see that one group of the color spectrum is very dull, which co-relates to the dullness if wearing glasses if the lenses are ultra-violet lenses even if it is comparitively less dull than the beam of colours that are reflected through the glass triangle.
  • Secondly, we can see that the other spectrum only produces the colors that are cooler (colder) than the warmer colours, which also relates to the fact that the green-blue-violet-pink beams are released through Ultra-violet light. (Hence, the name, “UV”)
  • Keep in mind, that the laser pointer is now rotated EXACTLY 15° (fifteen Deg / 0.261799 Rad) from its original angle.

I want to clarify if my supposed “theory” seems to be correct or if someone gets inspired to research on it more because science is all about knowing the phenomena around you. I want to get corrected or know that I am correct. I hope to get a reply soon.

Hello, I have the idea of water simulation, Let water fall down when there are space to move down, otherwise move sidways randomly
But it has a problem, No siphons can exist, Why it´s a problem?
Well, The siphons exist in reality
So I would redesign it
Let say pressure exists
Say score = (Reward for falling down) + (current pressure - picked adjacent cell pressure)
Say water want move to lowest pressure
Do you think it has the problems?

(Sorry late announcement) New rules for the studio, I tightened it a bit after the studio became popular.

1) Do not spam
2) Only add projects related to STEM, any other projects would be taken down
(STEM projects are projects designed to teach you STEM, which can be done through games, engines etc. If your project uses technical code but is not mainly designed to teach STEM, it does not count as STEM related.)
3) Be nice to other developers or scratchers
4) No advertising (Unless you're advertising a project related to STEM!)
5) You have the right to remix other people's projects as long as you give credit to them, and you change something

Well, can you please elaborate what you mean by “picked adjacent cell pressure?” I'm pretty slow are understanding complex things, sorry! Anyways, if you want to also simulate negative pressure or zero pressure in the score, you should probably make a condition of it like if it is bigger than the current pressure, the adjacent cell, then it would be negative, else returns more than zero.

And also, I would like to understand the adjacent cell pressure incase if there wouldn't be a problem with simulating water via low pressure.

Oh, so y'mean that you want to calculate the score of all the neighbouring cells rather than just one cell? That says something.
You must be saying that…
  • Current pressure is the pressure that you have set at the starting. (NGL I still have a doubt in it)
  • Picked adjacent cell pressure is the pressure of water or fluid that has been applied to (average) of the cells surrounding it. (We could assume that! Sorry I just can't tell much stuff without significant elaboration. )

But one twist, To guarnattee siphons exist, I need, something
Each red cell gets pressure of +10 each tick (to prevent staying in same location)
If it is not a red cell or wall celll, it decreases by 4 (to prevent to going high pressure)
Wall cells is needed
