Wang's four-scroll oscillator test 4 https://video.joostrekveld.net/videos/watch/272d7e4f-2aef-45f2-86c8-a4c5e0ee0d4c Experiments from 2017 exploring Wang's chaotic four-scroll oscillator on an EAI TR-48 analog computer from 1963 in fast, continous mode. Parameter 'a' is 3.0, and 'b' is being varied from 0.0 to 2.0. The trajectory is manually rotated around the X-axis from time to time, to get a sense of the 3d shape of the attractor. The equations are: ẋ = x − yz ẏ = x − by + xz ż = −az + xy Thu, 03 Sep 2026 03:02:47 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://video.joostrekveld.net Wang's four-scroll oscillator test 4 https://video.joostrekveld.net/lazy-static/avatars/e35ea6d1-b888-421d-b49f-14ee9051e5ed.jpg https://video.joostrekveld.net/videos/watch/272d7e4f-2aef-45f2-86c8-a4c5e0ee0d4c All rights reserved, unless otherwise specified in the terms specified at https://video.joostrekveld.net/about and potential licenses granted by each content's rightholder.
