Hello I joyfully announce
The making of three molds for 'Trio number Three' has commenced. I'm temped to glue the molds together into one mystery object Guess I'm not that brave and stick to the plan.. Three new pieces on the way.

Quilt, Anna Williams

I was thinking that if I had this on my bed, I couldn't sleep in it. I couldn't handle having this many different pieces touching my person.

This is like a quilt version of static on a TV

"This is my bed, it can't sleep."

Anyway, it's in a museum. I guess it's not meant for a bed. There is an underlying order. I was thinking too about how light can be refracted into a rainbow, this is like, the rainbow broke.

Really cool work

On May 1st 1890 in Paris, left-wing activists wore a red triangle:

One for 8 hours work,
one for 8 hours leisure,
one for 8 hours rest.

I have Fujichrome R25 Single-8 8mm film on which one of the color layers has spontaneously formed #Sierpinski #triangle #fractal like patterns, all over the whole 15m roll.

It is unclear if this has happened through some biological or physical process, and would like some help finding out.

I have found an interesting geometric fact: suppose you have a hexagon of side 1 and duplicate and enlarge it by the golden ratio 𝜑; the distance from one vertex of the unit hexagon to a vertex of the bigger hexagon 60° apart is √2. Furthermore, if another hexagon reduced by 𝜑 is drawn inside, the distance from one vertex of the unit hexagon to a vertex of the smaller hexagon 120° apart is also √2 [first figure].
This boils down to the fact that a triangle of sides 1, √2, and 𝜑 has an angle of 60° opposite to side √2. That triangle is very remarkable as it contains the three more relevant algebraic geometric constants: √2, √3/2 (altitude to the bigger side) and 𝜑 [second figure]. Of course this can be also used to construct 𝜑 from a square and a triangle (I bet this is known). In the follow-up some artistic designs exploiting those facts.

New series: Underestimated instruments. The triangle.
In our beautiful house, with its 22-year history that it has experienced with us, there is something to discover around every corner. It is a great treasure trove for music, art and rock ‘n’ roll. We are trying to preserve it, as you know. Important things would be lost, such as our triangle collection. A good friend of ours, who works as a carpenter at the municipal opera, has given us old percussion instruments from his family’s estate. We are not a museum, so we use it; you have heard some of the things on my records.
Now our long-forgotten triangle collection has turned up. Anyone who has seen a symphony orchestra knows that it is quite an important instrument and not just something played in kindergarten. These are tuned triangles for professional use. So, for those who have not yet learned an instrument, there is hope.

Some #Mathart based in triangles. The idea is to start with a set of triangles connected by their sides, and iteratively selecting the larger side in the set and dividing it using a simple definite rule (I don't use randomness). Stop when all sides are less than a given value. Using the research pointed out in my previous post, each triangle is assigned a colour just based on its shape.

In my research for new #Mathart , I have developed a nice chart to show the different types of triangles that exist (1). The idea was to classify them by how they look visually. The chart starts from a horizontal segment which will be the largest side of the triangle (or one of the larger). Then each point of the chart represents the triangle formed by joining that point to the ends of the segment (in fact if we are not interested in distinguish chirality half of the chart would suffice, but I find aesthetically nicer the symmetric version). By looking at it I have realized that isosceles triangles can be split into two visually different types: pointed and squashed. In pointed isosceles triangles the different side is smaller than the other, in squashed ones the opposite. Of course obtuse and right isosceles triangles are always squashed. The second image is what you obtain if the initial side is not necessarily the largest (colour codes are the same).

(1) Which is not new, I have found something similar in Hebrew: https://commons.m.wikimedia.org/wiki/File:Moduli_space_of_triangles_1_he.svg
By the way, it would be nice if someone could develop an image search which understand 2D geometry.

Dear Lovely Peeps,

This is GORGEOUS. Make sure sound is UP. Trance-inducing even to watch, but the rhythm sound is at least as much part of the performance.

I have never seen a juggler build his entire work around an external prop, but Michael Moschen does it so well.
