Is infinite zoom originated from Mandelbrot set?[edit]

Is infinite zoom originated from Mandelbrot set? Rizosome (talk) 03:44, 1 September 2021 (UTC)[reply]

What is Infinite zoom? ←Baseball Bugs What's up, Doc? carrots→ 04:04, 1 September 2021 (UTC)[reply]

This is example of infinite zoom. Rizosome (talk) 05:42, 1 September 2021 (UTC)[reply]

The Powers of Ten films precede the discovery of the Mandelbrot set. The 1977 version starts with a zoom out from a human scale to one in which clusters of galaxies are mere points of light, and then zooms back in to the original image and continues to the subatomic level. Long zoom sequences had been made before in films, but nothing as long as this.  --Lambiam 08:06, 1 September 2021 (UTC)[reply]
No, it is more related to the Droste effect. The Mandelbrot set is a mathematical description which, when visualized, gives a cool fractal geometry. Since this visualization is self-similar, an animation of it will show (approximately) repeating patterns when zoomed enough. Rmvandijk (talk) 09:36, 1 September 2021 (UTC)[reply]
A zoom on the Mandelbrot set can be seen here (Youtube) or you can choose your own area of zoom here. Mike Turnbull (talk) 11:23, 1 September 2021 (UTC)[reply]
It should be noted that while the visualizations of the Mandelbrot set are self-similar, being self-similar is not a defining characteristic of fractals. See This video for a good explanation of fractals and their properties. --Jayron32 16:00, 1 September 2021 (UTC)[reply]

Are there any good organizations that help specifically Narwhals?[edit]

Are there any good organizations that help specifically Narwhals? 2001:569:7D98:E00:98C2:EEE7:2572:77E4 (talk) 04:20, 1 September 2021 (UTC)[reply]

I don't think that Narwhals specifically need support since their habitat is the Arctic and their conservation status is "least concern" (see ref in article you linked to). However, you can find charities that support sea creatures by Googling Narwhal + charity (which gives ORCA and WWF, for example). Mike Turnbull (talk) 11:33, 1 September 2021 (UTC)[reply]
It should be noted that, according to Narwhal, the species was, until recently, categorized as "nearly threatened"; meaning that conservation efforts were needed to raise their numbers. There may be some concern that additional efforts are needed to maintain good, healthy populations given their recent status change. The World Wildlife Fund has information on their narwhal conservation efforts here. Perhaps the OP could look into that organization. --Jayron32 15:59, 1 September 2021 (UTC)[reply]

Thank you Jayron32. I will look into the organization! 2001:569:7D98:E00:98C2:EEE7:2572:77E4 (talk) 20:08, 1 September 2021 (UTC)[reply]
