12/18/2023 0 Comments Golden spiral nautilus![]() Interaction between materials happen at the atomic level not the sub-atomic. It’s one particle moving forward and backward, imparting that momentum to the next particle, which imparts it to the next one, etc… just like a newtons cradle. Remember, sound isn’t a particle that moves from location to another. However it is SO significantly less than C that we give it it’s own measurement, the speed of sound. The speed at which atoms transmit force within a medium is defined and (as you mention) is less than C. But a couple of general corrections/clarifications: So honestly, I think they're all just repeating what they've heard, because we have such a strong (yet mostly incorrect) "the golden spiral is everywhere" belief in our culture. For a golden spiral, the same principle applies, just with distances of 1, φ 2, and φ 4 instead, which actually increases the gap you would get at the halfway point. But if the gears touch when the radius of 1 touches the other's radius of 2, then the distance between them must be 3, so when turned to their midpoints there would be a gap of (3-2√2) = 0.172. So I bet they can't be true logarithmic spirals at all.įor example, a logarithmic spiral with a starting radius of 1 that increases to a radius of 2 in one cycle must have a radius of √2 = 1.414 at the 180 degree point. ![]() For them to be the same shape, the increase in radius must be symmetric (probably linear). If one of them is increasing exponentially (as in any logarithmic spiral), then the other cannot be the same shape, because they won't touch when they're both halfway turned. Here's a thought though: as the gears turn, the radius of the touching parts must always sum to the distance between the gear centers. Please direct your posts to /r/gifrecipes.

They can be funny, but just consider this.Īny post that has been submitted in the past 3 months or is in the top 100 of all time cannot be reposted and will be removed. Your title must be informative of what is going on in the gif, instead of the good ole "Look at this gem" or "Just a wheel". We won't go hunting you down, but at least be considerate of the creator. ![]() ![]() These are reliable sources and thus we would love if you hosted your gifs using these sites. The preferred sites for gifs to be hosted on are imgur or gyfcat. You want this sub to have more content? Go to the subreddits below to learn how to make/request a gif! From chemical processes, to how plants work, to how machines work, /r/educationalgifs will explain many processes in the quick to see format of gifs. Gifs are great at getting quick to digest info, and /r/educationalgifs strives to give you educational info in this quick to digest format. But please read the rules before you post, in order to help the mod team moderate, while also making this a better place to post. As long as it is educational, and a gif, it is fine. In /r/educationalgifs we strive to have short gifs that educate the subscribers in some way. ![]()
