Are the Robots Waking Up?

360 documentary on ABC Radio National recently has this title.
"Are the robots waking up?      Sunday 6 April 2014 

Are we nearing the singularity, the point where philosophers say the computer programs we create will be smarter than us?
Artificial intelligence is all around us. In phones, in cars, in our homes. Voice recognition systems, predicative algorithms, GPS. Sometimes they may not work very well, but they are improving all the time, you might even say they are learning. 
Come on an entertaining journey through the ethics of artificial intelligence or AI, the science behind intelligent computer programs and robotics. Some software engineers think about the philosophy of the artificial intelligence they are creating, others really don't care.

Interesting Comments online.   Especially regarding consciousness.
What if robots are made smarter than humans,  and they create programs even smarter?
Was it Prof Paul Davies who said that Modern Physics is a message from the Future?.....

Swirling Shapes

Jay Harman has always been fascinated with the efficiency he sees in nature. Human creations come with problematic side effects.  In nature there is no waste. Everything is used. In his book The Shark’s Paintbrush, Jay Harman describes designs in nature being copied in the human world, from the shape of wings and the way water flows down a plughole, to the marvels of individual molecules which can afford so many advantages in our manufactured world.

The Latest Seashell Model

Long time no postings -  excuse is I have had to extensively repair holes in my caravan after the visit of a big brown snake with a black head, inside chasing a mouse 8th Feb 2014!  Not every day does one have such an excuse.

So I was excited to sit down and begin to crochet another new model.  I did it the hard way -  first row with right hand;  second and alternate rows with the left hand, without turning.   You can do it the usual way, using only one hand to work the yarn;  it makes a ridge.  I wanted an even surface on the outside.  Well,  as you can see,  it is not a perfect model,  but it looks a little bit like the shell on the cover of Barry Wilson's book:-

It began with 8 stitches,  to 13,  to 21,  to 34,  to 55,  all with 4 rows between;
to 89  repeated for 12 rows,  then 55,  then 34..
You can see the LHS is wider-  I used 2 strands of "2 ply"cotton  for 5 stitches all along the edge,  and at the beginning; (the oldest part of the shell becomes thicker, with time....)  the middle has 1 strand of 2 ply.
The RHS has "1 ply" equivalent ( candlewick cotton).
I had to stitch the top rhs corner so all lines come together at the tip
The rhs curls under to form a right hand spiral which is usual in Nature.  Left hand spirals do exist but they are rare-  maybe in another dimension or universe the rule may be left hand.....

Please see previous post 2/3/2014- "The Real Seashell, Updating" for method behind the structure.
Also past posts cross references - 2/2/2012,  1/19/2012.....  it is not possible to repeat everything all the time.

I have  drawn in the join lines....a 377 model might be better.... or an even bigger one!
When sewing the 34 row to under the last 89 row I used a knitting needle or skewer to hold the piece (like an extra finger) so that I could stitch the 34 row almost from underneath.  I shall have to do a drawing to describe the top needs more study.
Maybe the first rows might be better with only 2 rows between them.  I supported these models on a Japanese pillow filled with buckwheat = like a beanbag.  I shall make some more small beanbags because these models tend to topple over on flat surfaces.  The author, Aydin Orstan, of  uses plasticine to hold up his real snail specimen shells.

---more seashell models will be made in good time---


The Human Torus

Here are pictures from Nexus Magazine.  You can also find this on YouTube-  


Here is my own drawing of "Vitruvius Man"

This simple drawing is made with reference to Leonardo’s original, which can be seen on Google Images and on Wikipedia,  etc.
In 1498 Leonardo da Vinci drew the “Vitruvian Man” – a swarthy angry looking man, spread-eagled, to show human proportions.
Vitruvius was a first century Roman architect who believed the proportions and measurements of the human body, which was divinely created, were perfect and correct.  Therefore he proposed that the dimensions of a temple should also relate similarly.

Interesting to observe proportions of the body.

More to come........

The Torus

This will be the Age of the Torus.  See also the documentary "Thrive" on YouTube.
Check out the Keshe Foundation.

Torus Fun Video by ieoie
Sacred Geometry

I tried to crochet a torus one year ago, but the result was too frilly around the edges, and tight to breaking point at the centre.

Here is mathematical modelling , in accordance with Fibonacci Series to enable increases in size:-

The Plan is -- to make a model, whenever I can manage it.
More text and info to follow on this fascinating subject!

The Real Seashell, Updating

This space is for the documenting of making a better seashell model, adding time and space, etc.

These images are from a previous post.

More work will be added asap.



Another model has been made  = a black and white one.
Previous posts have been updated = 2/24/2012  and 1/19/2011

The top of the shell is a real challenge in understanding the real thing.
Mathematical model of spirals similar to the torus?............will try.....

Adding Time and Space to Seashell Models.

One can add length and time to knit and crochet models.  While the leading edge is growing, also the edges behind are growing;  I try to work it like this:-  Similarly with thickness.  One can glue several layers together.

Here is the Pattern:-

You might notice that the Lucas Series is involved-   2,  1,  3,  4,  7,  11,  18,  29,  47,  76,  123,  199,  322,  521,  843,  1364,  2201,  3571,  ..........I shall later add the extra, relevant Patterns.

89 stitches

144 stitches

233 stitches

Up to 377 stitches

Adding 610 and 987

dividing the shape into 5 and gathering along the ribs, moulding to shape.  One could use Aquadhere glue, diluted somewhat to stiffen the model..  The hinge area needs several layers to make it strong and thick.  Some seashells can be 2cm thick at Umbo.

dividing the model into 5;  each edge is about 200 stitches long.
Maybe one could make a model in paper or fabric by gluing 5 layers next to each other.

The full model is stitched together along its sides and displayed like a vortex.

curling the model to form a spiral vortex.

(Update 16/4/2014.....   there are 2 more configurations,  such as for the earliest Hyperbolic shape seashells eg posts on 5/25/2010.  Also  Nautilus (Cephalopod) shape 5/3/2011.   I shall  have to make them and take photos.)

In following a Pattern for the Fibonacci Series
One might need to count when knitting or crocheting,  as shown in much earlier Patterns
One knits by starting from the widest edge and working back to the small numbers.

Back in 28/4/2011 there were Patterns for crocheting the Vortex.  There are similarities with today's Pattern.

Also in 23/6/2010 there was a green shape to 610 stitches;  the edge was exceedingly frilly.  The algorithm for Pattern was Fn = 2Fn-2  + Fn-1  eg 89 = 2 x 34 + 21

See 12/12/2012 for the first 135 Fibonacci Numbers.

Please see YouTube for a very beautiful Irish Crochet seashell.
It is "by lacefromIreland."  Seashell in Irish crochet lace.
It is not in accordance with Fibonacci numbers, but it is charming work in its own right.


One can also learn how to crochet, even left handed, by watching tutorials on YouTube.  eg Pip Lincoln is very good.


Aha,  I have managed to find the Irish Lace Seashell from Youtube to embed in my blog!
