Seashell models**


This amazing image came from Facebook newsfeed from Nassim Haramein.  Most appropriate for my blog here!  I shall check up the origin.......asap.

Insert 10/4/2015
Caracas born Venezuelan artist Raphael Arajuo makes "these wildly detailed drawings".  Here is web link to see them,  and his website is http://www.raphael-araujo.com

There are six models that I am crocheting just now,  all tentative efforts, not yet finished.  Not perfected yet........ I shall publish as soon as it is to hand.

The Seashell Models Continue.**

Here I try to imagine what the inside of the tall seashell looks like.  It still is not exact.  Thinner column inside.  Height is 3 or 5 times the width.  Tricky to make.

One observes with wonder that the mantle of the live creature inside does all the mathematical work exactly,  building up the calcium and proteins and coloured minerals via glands.  Is there a Nature Spirit or spiritual creator being at work every second in the life of this organism?
It is said that of even we human beings "we are more like flickering flames than lumps of meat" ....I need to find the right quote...  ***12/3/2015  I corrected some words,  and still have to find the author when I get back home
-------------------------------

3/4/2015  more:  It was Candace Pert on Life Matters ABC Radio,  but I lost my notebook.  You can find YouTube video interview with the late Candace Pert,
On the brain.  Interestingly one video on miraculous cures....she said - we have been lied to ----cancer is caused by pollution!
------------------------------

**Is spirit and matter like a strobe light?
 Physics articles on Facebook feed indicate something like it.

aah---here is the article:-

Nobel Prize winning physicists have proven beyond doubt that the physical world is one large sea of energy that flashes into and out of being in milliseconds, over and over again.

------------------------------------


My own diagram of the inside of a real seashell, above, was drawn and published previously.  
Post of 4 May 2013.
The very inside is shown to be paper thin.


This model above  has been published earlier  (post of 19 January 2012) and subsequent posts, in "A Proper Pattern"    which has had more than 500 pageviews already.  It is not a perfect crochet pattern yet,  the top is tricky;  am working on it.

******************************************


Here are two new efforts,  just tentative ones.  I wondered what shape would come if one used the algorithm I discovered in 2010 to make the first seashell models...
 ie   Fn = 2Fn-2  +  Fn-3 of the Fibonacci Series.
 eg  ....  13=2x5 +3,  21=2x8 +5,  34=2x13 + 8,  55=2x2x21 +13,  89=2x34 +21,  144=2x55 + 34.  etc.

The top image (144 stitches crochet) is like a top shell.
The lower image (89 stitches crochet) is like a whelk.

The difference is the 2x side is one one side in one model,  and it is one the other side for the other,  ie  144= 2x 55 + 34   versus   89= 21 + 2x55.
The 2x  area of the Fibonacci fan skews the frilly edge one way or the other.
Also the thin central portion of the Fibonacci fan is accordingly placed.
Here the stiching up of each item is as recently determined =  nothing like the way it was done in 2010.

*******************************

I am working on 3 more different models,  not finished yet.  Very tricky.  One tries one way and it doesn't turn out quite as expected.  So one has to start again and again, experimenting.

There are 2 more permutations for the above algorithm equation,  
ie  144 = 17 + 2x55 + 17,   maybe this might become a bubble shell?  skew is in the middle.
or,,,,  34 = 2x13 +5 one row, turn,  55 = 2x21 + 13 next row, etc,  so the skew is even over piece.

Plus make a plain row between each increase row...
put stripe rows of a different colour in to designate particular rows...

Plus how much of the model needs to be paper thin in the middle?  1.2?  1/3?  1/4?

Then there is the usual algorithm I use 
 ie 4 crochet stitches make 7  which is adjusted to 13 makes 21 stitches

**Plus the new,  for me,  algorithm  of 4 stitches into 5  ie crochet in 3 then 2x into 4th, making 5.  
My reckoning is that this fits the fibonacci series together with the half fibonacci series,  published earlier.  
Here one fibonacci number made into the next fibonacci number takes 2 rows' work 
 whereas the 13 to 21 algorithm does it in  one row.

**********************************

Meanwhile it is autumn and peaches (three trees full) are ripe. 
Making jam and preserves is all done now,  and I might just get around at last to focusing on these seashell models,  that is, if I don't get distracted by something else. 
 Summer has been terribly hot in my caravan-  34 degrees C  even up to 37,  39!  At least we have survived  - no bush fires this year in our region,  tho it has been fiendishly dry - no rain.




Gorgeous parrot.   Maybe a rainbow lorikeet,  but I do not know my bird names exactly.  Birds enjoy gnawing at fruit.  The Black Swamp Wallaby and maybe a fox have been feeding also.  Plenty for us all.  One has to collect up all the  fallen fruit and put into black plastic bags into a bin to compost and to kill any fruit fly.  Luckily only a few fruits have inside rotten brown with fruit fly this season.

Auger Shell With Tall Spire, model making Continued...**.


A previous diagram, further detailed.  Pleas click on images to enlarge them.





-------------------------------------------


Mathematical Model for a Seashell with a Tall Spire.**


Two Augur Shells, each 90mm in length, above.
Tracing of ventral view of one shell, below.





A rough model for a theoretical auger shell.




















The cone is made.  Spiral is drawn up the sides.














Snip up the red line. flatten out.  This is the shape need for the top surface of seashell














-----------------------------------------------------



I am guessing at internal column of shell,  must be thinner than outer surface.














Measure the heights at each level of the sutures:-

Oh dear,  the blog won't allow more....to be continued......
.....................................

10/4/2015 more:-
 actually, the inner walls should be more horizontal  and join to fuse with the central column, to make a funnell like spiral downwards.... diagram to follow......

Padding needs to be just at the top so that the laye paddingr under pushes the inner wall towards the centre.  I have been stuffing some models too much!...

Fibonacci Ripples Merge into a Spiral**

This was posted early on in this blog.
Notice that the radius eg of circumference 34 units is almost 1/10 of the next number 55,  all the way along.

Please click on images to enlarge them.

Theoretical spiral made by merging the Fibonacci ripples above.

More work to follow, comparing this with the spire of a real seashell......
We can also try to project the lines up into a cone of varying heights........


----

More work,  12/2/2015


Compare these, the theoretical, and the real.  Almost exactly the same.





Three short spired and one long spired seashells.
One can make mathematical models by projecting the merged spiral up into cones of varying heights.
=  next post!

Beach and Rock Platform, Little Bay, Sydney.

It is 6 hours by train from Young to Sydney,
I catch the 393 bus to Little Bay,  at the end of the line, past Uni of NSW at Kensington, past Maroubra.  Walk by Hoop Pines in the old Hospital grounds.

When I worked in a microbiolagy lab at a hospital our lab manager told us a story-  Little Bay Hospital once had a leper colony.  A visitor was on the beach watching an inmate in a boat fishing.  When he threw out the line, the man's arm fell off.  "Did you see that!" said the visitor.  "Yes" nodded his companion and his head fell off.

Stained glass window in Chapel overlooking the Ocean.



Magnificent clouds over the Pacific Ocean.



 


Little Bay headland.  Last time I was here was 1966, I think, as a Uni student on a Zoology field trip.


A sign along the stairway leading to the beach describes the biodiversity to be found there.

(Click on images to see them more clearly.)








A black elephant snail, Scutus antipoides was put on my foot by a fellow student,  long ago.


Seagulls.





Two shags (cormorants) on a rock



Once the rock platform was thickly clothed in Cunjevoi.
Now there are none.  Rock pools look empty.
There may be more seashore intertidal life further on, but I was alone there and what if I slipped...?..


I take a closer look.  There are limpets.



and black Nerita,  it used to be called Melanerita



Some Austrocochlea.  The common brown seaweed Hormosira looks like strings of large beads.


A nice surprise is little green seastar!  There were two of them.


Black and white Morula.  Pink weed.



No more Scutus.  Or crabs or sea urchins or green sea lettuce Ulva.
 Blue ringed Octopus is deadly poisonous.
All the juicy stuff is scavenged by collectors, to eat or sell. They say it is Asians do it.
The rock platform at Malabar Beach, just to the north, has signs "No collecting".  I plan to catch the bus back and go there but I catch the wrong bus.......
Across the way, Botany Bay, is Kurnell.  There might be more shellfish there.........

The walk up behind the headland reveals unexpected flannel flowers!  One sees them rarely now in Sydney sandstone country.  Just a nice remnant of coastal heath with its wildflowers and it is next to a huge golf course.  The country of the Australian Aboriginal peoples was beautiful once long ago.










This is a collection of empty seashells, found on the water's edge, that I took home:-



------------------------------------

There is more story, from 30 May 2011-  a newspaper clipping:-



Read by clicking on image and use a magnifying glass!  
40 year old former Navy medic and eco-vigilante chooses to wear camouflage gear and night vision goggles to video poachers on Long Reef rock platform.  The video is given to police.  
Whole families take a bus to Palm Beach and use crowbars and tools to prise off the molluscs etc from the rocks.  Soon there will be not much left. 
...............................................
The practice of plundering marine life was begun 200 years ago.  Kate Grenville writes in "The Secret River"  how white men pillaged the Hawkesbury River's oyster mounds and live oysters by the ton to ship away for making cement.  

We built huge stone Court Houses and Prisons and such.  I look at Sydney and tho I love it in my way I feel that so much greater Natural magnificence has been lost.  Sacred rocks made into buildings.  Sacred ancient trees cut down.  Biodiversity of a whole Continent decimated. 
 I long for and regret what has been lost.  We Europeans lost our Dreaming long ago-  war etc. 

This project of mine on crocheting seashells is just  a small reminder that we stand to lose it all, by plunder, pollution, ocean acidity, unless a miracle of conscious change might occur to Value and revere the Natural World.  
Many people feel the same-  we try to do our best in our own quiet way.

Here is Heterodontus portus jacksoni.  
Back in a post of 24/6/ 2010 called "Heterodontus does crochet"
 I crocheted a "shark egg"which is a spiral shape.  
5 chains.  Then 5 stitches in each loop makes 25.  Then 5 stitches in those 25 makes 125.  Then......  I forget....it looked like a shark egg, black.  
My plan was to visit Huskisson to find some real ones, empty, washed up on a beach, to study them.
  But I haven't been there yet.  Maybe soon.


I believe that Sydney Harbour (Port Jackson) is a marvellous Marine Park.  Poachers can't easily get down there.  There are sea horses,  all kinds of saltwater creatures.


On Facebook, Rie Tamaru had a beautiful picture of herself scuba diving-  she was holding a large live Nautilus in all its beauty.  ***18/3/2015  I checked today and yes, the photo is still there.

On You Tube you can see the Soft Corals of Port Stephens with strange sea creatures.  Even this is under threat from human carelessness- rubbish,  fishing lines-  but it was a revelation to me to see such a fabulous unfamiliar ecosystem. *** 18/3/2015  this video is shared on this blog in the next few posts.  

-----------------------------------------------

*** 26/1/2015
Videos from YouTube have now been shared on this blog.
If you have the time see "Accidental Eden-  Cuba, " especially the coral reefs.
Staghorn corals survive here.  The reef is still healthy-  you know why?  Cuba was forced to grow food organically because no fertiliser was available after the fall of the Soviet Union  ~50 years ago........there is advantage in being behind.  Modernity costs us a lot.....
What will happen now that America is showing interest in Cuba?
