I got a design which wobbles infinitely! :D

Draw an iceberg and see how it will float

#32A version which has some preloaded shapes and shows the forces explicitly, inspired by the same tweet: https://engaging-data.com/iceberger-remixed/
This is all from 2021 and I feel like I’d seen this prior to that but I can’t find it.

Re: Draw an iceberg and see how it will float
#34Got a bit frustrated because I couldn't get anything except a flat surface above the water, then read the tweets below and realised that's the entire point: https://threadreaderapp.com/thread/1362557149147058178.html (Many thanks to Elon for making it impossible to read more than the first tweet on x.com without an account...)
My mental model is of each side (think left/right in 2-D) of the iceberg competing with the other side to float to the surface by rotating the iceberg around it's center of gravity. The only stable positions are where these left/right rotational forces are balanced.
If an iceberg is currently floating in a vertical orientation where more of it's mass to one side of it's center of gravity (bottom half) is underwater compared to the mass on the other side (top half), then it's going to tend to rotate until both sides are equally above water, so (depending on mass distribution) horizontal orientations are likely to win over vertical ones.
Of course an iceberg could balance vertically, but that's like balancing a pencil on your finger - not the most stable, and any disturbance (such as the initial calving event) is likely to rotate it into a more stable horizontal orientation.

#35From my brief experimentation I have determined that the precise initial orientation of the dick^H^H^H^Hiceberg is critical to its final orientation.

Try something that has no flat surfaces. For example a five pointed star.

#37My fun was to try to get the widest underwater part with the narrowest top showing above.

#38Author here. Glad to see this making the rounds again after a few years. Go science! Support your local climate scientist!
Great education simulation! Thanks for working on this.
Curious about this: I am hitting a boundary-condition like behavior drawing a straight line at a 45 degree angle similar to the sibling comment.
Curious if it is due to physics or due to the simulation.

It seems to have trouble with long skinny shapes, I had one that would keep moving and occasionally flip over

#40No idea if others at Twitter suggested this as I can't read the thread (and have no intention to subscribe) but a nice add on would be a score inversely proportional to the travel an iceberg would need to obtain a stable floating position, with ideally the very hard goal to draw it already in a perfect stable way, waterline height included.
