Neither of those shells line up with the Fibonacci spiral, they're just spirals so they look kind of similar at a glance.

The whole golden ratio in nature thing is overblown BS.

In fact, I just did a bit of reading about the Vitruvian Man and it turns out none of its ratios match the golden ratio and the accompanying text only mentions whole number ratios.

You just demonstrated my point, the spirals only weakly line up for about half a turn and then diverge completely.

No I mean a 3D Fibonacci spiral, projecting it on the vite spiral, finding the rotation parameters, and finally fit it.
It might give infinite solutions tho.

Instagram is useful, like twitter or youtube.
One can contanct people with the same interest with few clicks.
One can create subnetworks with shared interests.

Although I'm sure you use instagram to share selfies and meme. -.-'

Barely any of those actually line up with the spiral.

>>8275026
If you have to put that much work into fitting it then it's not that amazing. I can fit some arbitrary data to a polynomial but that doesn't mean that there's some intimate connection between the data and polynomials.

If the fitting has a logic behind, in my opinon make sense.
Not everything must respect the student T test or the normal distribution.

Yes this is my objective, bringing science to people. No wait... this is the job of astrophysiscist.

I don't understand why math and physics gain so much interest in the internet population.

This is the first thread that has a decent amount of replies and started with a weak mathematical assumption.

When I tried to advertise my goal to bring biology to everybody I literally never succede to make a decent thread.

>>8275056
Stop pulling shit out of your ass. It is not the job of an astrophysiscist to spread pop-sci memes on instagram or "bringing science to people" (as you so redditly put) in general. Astrophysics also barely are about biology.

m8, the discrepancy is huge

>>8275041
Try lining up a fibonacci spiral with them, they don't line up well.

The truth is that the fibonacci spiral is a specific example of a logarithmic spiral. Logarithmic spirals do pop up all over the place in nature, particularly in shelled animals because as they grow, the shell has to get bigger to accommodate their size. Very few of these line up significantly with the fibonacci spiral in particular but they look similar at a glance because logarithmic spirals all have the same general appearance of getting tighter towards the centre.

An example often touted by golden ratio believers is the Nautilus shell but its growth ratio is actually between 1.24 and 1.43. The golden ratio doesn't even lie in that range.

>>8275049
All that you'll manage to do is fit some weird shifted version of the spiral to it and be left with something that is no longer the golden spiral, making your point invalid.

>weird shifted version of the spiral to it and be left with something that is no longer the golden spiral

Well the spiral in the vite is a helic that grows, I'm interested in why the spire looks regular, which I think is a way to spare energy while looking for the highest solar energy intake.
I'm not sure if is Fibonacci, or logarithmic, or a simple random spiral.
Although the method I proposed, might help to clarify that.

taking a 3D spiral, projecting it from the camera direction and finding the parameters. Doesn't seem to me such a complex fitting.

>>8275071
>Logarithmic spirals do pop up all over the place in nature
Glad you agree then

>>8275082
if it did there would be no red arrow. it doesn't line up at all ;)

>>8275082
What are my red arrows there for then?

It lines up for less than a full turn, then it goes way off. Cosine sort of lines up with a quadratic function for a bit too, doesn't make them the same.

>>8275085
Yeah, logarithmic spirals are all over the place. This doesn't make the golden spiral any more important than any other of these spirals.

>>8275084
>taking a 3D spiral, projecting it from the camera direction and finding the parameters. Doesn't seem to me such a complex fitting.
That's distorting, you could fit it to any spiral if you did stuff like that.

>>8275089
Technically if you keep the projection parameters fixed like the camera point and the focal distance, you'll be able to find unique solution.
(maybe, I'm a biologist and math has always been complex for me)

>>8275098
Mate, you can measure this yourself. Read about how log spirals work and you'll see that spiral shells have all sorts of different growth parameters. Some of them might be close to the golden ratio but most aren't (like that example).

The golden spiral is very pretty but it has no significance in nature over other spirals of the same type.

I'm a biochemist, with a master degree from the ETH Zürich.
I did 2 years of PhD in the field of structural biology and electron microscopy.
After having a publication I left the world of academy being full of faggots lusting for a paper.
I decided in my free time to talk about biology with strangers, since all my friends all got bored of me rambling about theoretical stuff.

Of course it doesnt fit every single spiral, mate. But most of them are logarithmic

It is not the golden spiral

>>8275112
(You)

>>8275120
how you did that? whats the spiral function?

>>8275119
Are you arguing for the ubiquity of the golden spiral or logarithmic spirals in general? There's no doubt that logarithmic spirals are everywhere, I'm just saying that the golden spiral isn't special.

>>8275123
It's from the Wikipedia page for logarithmic spiral

>>8275120
So?
Where did anybody claim that every shell lines up with the "golden spiral"?

>>8275131
Oh you didn't do it then ;'(

>>8275120
Even better example. Thanks for proving my point

>>8275132
It's kind of implied when people always put pictures of the Fibonacci spiral with the squares next to photos of shells.

>>8275135
If you want to know, it's a log spiral with growth parameter 1.759

Don't go off thinking that number is special though, it changes for each creature.

>>8275150
1×7+5+9 -10 = 11
Last number is 9
> 9/11 confirmed to be golden ratio

fibonacci spirals increase in diameter as they grow. that vine's growth has a consistent diameter and therefore is not a logarithmic spiral.

Uhm, also whatsapp uses a telephone number. It's actually a risk, but pretty minimal, since the application is oriented toward security.
The application has 100'000'000 users.. I'm not really sure if they are interested in your specific phone number.

Your telephone number will be hidden, unless you want to share it.
