and for my physics/math folks check out the "about" section where I did the traveling salesman approach to minimize the driving time to hit all 61 restaurants

hey @culvers give some love to the folks visiting every Culver's in MN over 7 days https://t.co/KNMElHlL3p

New Blog post about how I race myself on my way to work https://t.co/sebSP7TAG3

[Andy Rundquist @arundquist]

It was close but today was my fastest ride home of the week. Here's the top two

Google Apps Script Web App to animate a race among multiple .tcx files (exports from fitbit, for example).

Proof of concept where you can take a picture with your phone and get a Google Gemini suggestion for a physics problem based on the image

This is from the mobile app I built for campus-wide challenges

First submission:
How disappointing
No eclipse for me today
I will riot now

[Andy Rundquist @arundquist]

Script to number your google doc headings (up through level 3). Yes, should have cleaned it up but hey, it works

Still playing with driving a pendulum by sending the pivot point around on a vertical circle. Here's how the poincare section changes as the frequency goes from 1x to 1.2x the resonant frequency of the pendulum

[Andy Rundquist @arundquist]

Here's a shot of the Poincare section as the radius of the circle closes in on the chaos point. The blue/yellow background is a density representation indicating where the red dots are clustering.

[Andy Rundquist @arundquist]

First an animation of a pendulum whose pivot is driven around a circle. Then an image of the Poincare section of the motion showing ~100k periods. Took a while to find a combo of circle radius and friction to get some cool chaos going!

here's the poincare section

Here's a fun project I've been working on https://t.co/TDTdVecC23

[Andy Rundquist @arundquist]

Here's the gif version (I think)

[Andy Rundquist @arundquist]

Working on a blog post about the colliding block pi calculation. Here's what happens if the collisions take a little bit of time (spring-like collisions instead of instantaneous momentum transfer). Number at top is the number of collisions of the small block (m2=100m1)

[Andy Rundquist @arundquist]

hmmm. It's an animated png but it looks like it's not looping. I guess you have to wait for the blog post :)

[Andy Rundquist @arundquist]

I know I should wait for pi-day for these sorts of things but for some reason I was thinking about this recently

I needed popcorn for this one.

so-called "no code" appsheet takes some good algorithmic thinking to use. Here's a vid for future me on how to do some tricky things with it https://t.co/NUeoAEfM36
