Science Sims

Based at The City College of New York, we are a group that builds science sims for the future. PI: @jameshedberg

Mostly with #p5js but some other tech too.

Super simple stellar parallax sim for #astro101

Everyone knows, however odd it seems, that physicists spend most of their lives on ramps that are at an angle θ w.r.t the ground, right? Now you can see what we see. #iteachphysics

@kilroi22 @PhETsims @p5xjs 😍 That's gorgeous. While the interactions are done by solving the normal Newtonian eqs, I'd hesitate to quote any meaningful values for G in ours. (it's set to '5' under the hood, but since I've disabled collisions, there's a little fudging going on at short separations)

[Science Sims @SciSims]

With the recent #AdobeFlashDeath (tip of the hat to an old friend), we'll try to fill some gaps in #scisims. Here's a @PhETsims classic done with @p5xjs . Give it a whirl. There's room for improvement so do report back via a GH issue or here. #introastro https://t.co/RQlNGR0nDu

@maalmeida85 It's still a wee bit awkward on small screens (but less awkward than a flash version 🤣). Works fine on desktops and tablets though.

Make a quick plot to show the quadratic y(t) function.

Do you want to know what color a star is? @JanVincentHarre and @DrReneHeller have a new paper out that provides insight. @jameshedberg has created a great visualization tool to go along with it. This is super for Astronomy 101 lessons or the Astro-curious https://t.co/KqakvVhkoo

[Science Sims @SciSims]

Here's the start of a new offshoot from @SciSims: Kinder-Sims! Some super simple, #stem related @p5xjs based sims for Pre-K level exploration of geometry and other topics.

... more to come I hope. (and no ads or annoying sounds...)

[Science Sims @SciSims]

@STEMcoding Figuring out how to use that is totally on my to do list for the near future. I just had a minor revelation about properly using noLoop() and reDraw() that I'm going to add to more sketches.

[Science Sims @SciSims]

@STEMcoding Well, yes, but I've never been sure what caused it exactly. Once, just setting noStroke() on a whole array of circles (like a set of trail dots eg) improved performance dramatically.

Here's the sim on display. It shows the blackbody spectrum and star color based on temperature. (Do test it out please and let us know how it looks on your device - we only have so many here at home) https://t.co/OXadG27hD7

[Science Sims @SciSims]

In case you were wondering what that noise was over the weekend, that was the sound of me figuring out the trick to getting all our @p5xjs sketches to look great and behave in all different shapes and sizes of browsers. Oh the difference a little <meta> tag can make.

[Science Sims @SciSims]

@arundquist looks like what I'd expect

[Science Sims @SciSims]

@arundquist I guess the f_k direction would be tangent to the green line from the animation, which would then cause the red line to curve upward. How's that sound? Cool question.

@ChatPhysics One of our favorite exercises: just write a sentence using common words like ‘acceleration’ or ‘power’ but make sure the word is used correctly in the ‘physics’ sense. Eg ‘the car accelerated quickly’ what does that really mean? It went fast? Large 3rd derivative? #ChatPhysics
