Round stone tool & round basket craft

Great apes construct woven tree shelters, using triangulated branches with a coil of leaves inside serving as a lining. Central African Bambuti people construct geodesic woven-branch domes externally covered with a coil of leaves to repel water. Were the first boats made from dome-derived baskets? Were they the arc (teba) of Moses (Hebrew) & Horus (Egyptian, eq. to Torus? see bottom of post), baskets covered with bitumen tar/pitch?
1560s, from L. torus "knot; cushion"

Basking shark vertebrae, from Coastal Paleontology [Unrelated to post title, but cool, like this stonehenge animation]
More info on roof, and how the stones were moved, quite similar to Dick Parry's
idea of how the Giza Pyramid stone blocks were moved in 1/4 circle wood cradles.

"No one knows what this crescent-shaped tool was used for, though it has turned up in association with Clovis points elsewhere. While the tool's middle edges are dull from grinding, its ends remain sharp. It is made of chert from the Green River Formation of southwestern Wyoming and contiguous parts of Utah and Colorado. This is not far from where the cache is believed to have been found, the three corners area where Utah, Wyoming, and Idaho come together."

Crescent-shaped knapped stone (scraper?) from the Holocene have been found at Lake Baikal, Siberia and San Miguel Island California and the the Great Basin of Utah and coastal sites, often of obsidian or chert. Neat pic.

Video on hyper-origami. Math * Computer -> a single flat sheet of paper can form super complex forms. Used for folding metal stents in arteries, and folding mirrors in outer orbit space.

I made a paper sphere by making a takraw ball of 6 paper strips, then another long strip to make 12 trefoil knots (pentagons) which filled in the pentagon holes of the takraw ball. Cool. I'm sure it's possible to make a sphere from one single folded sheet of square paper, but it would be complex hyper-triangulated.

Knots and lashings

Torus: knot or cushion, Latin (Egyptian. Horus?)
"upright slab," usually inscribed, 1820, from Gk. stele "standing block, slab," related to stellein "to set in order, arrange"
direction to printer to disregard correction made to text, 1755, from L. stet "let it stand," third person singular present subjunctive of stare "to stand, stand upright, be stiff," from PIE base *sta- "to stand, set down, make or be firm" (cf. Skt. tisthati "stands;" Avestan histaiti "to stand;" Pers. -stan "country," lit. "where one stands;" Gk. histemi "put, place, weigh," stasis "a standing still," statos "placed," stater "a weight, coin," stylos "pillar;" L. sistere "stand still, stop, make stand, place, produce in court," status "manner, position, condition, attitude," statio "station, post;" Lith. stojus "place myself," statau "place;" O.C.S. staja "place myself," stanu "position," staru "old," lit. "long-standing;" Goth. standan, O.E. standan "to stand," O.N. steĆ°i "anvil," O.E. stede "place;" O.Ir. sessam "the act of standing").
Stalactite = stylos, galact = drip... did the first temple columns derive from cave stalactites?

please have you some photo of your models of takraw balls ?

Sorry, I don't have a camera! Technically, I did not finish making the "completed" sphere, I filled in only some of the pentagonal holes with the trefoil knot pentagon (enough to fill 3 adjacent holes).

I meant in the conceptual sense, the missing holes have now been filled using the trefoil knot pattern. That had been a mystery to me previously.

Are you the person that gave directions how to make a single strip of paper into a pentagonal dodecahedron? If so, that is very nice!

Biagio Di Carlo said...

Thank you for the answer.
I am sorry but I am not the person that gave directions how to make a single strip of paper into a pentagonal dodecahedron.
Ciao from Italy.

A video on how to weave "Greek Paper Footballs", which is the same pattern as the Thai-Malay Takraw ball, is here:

This is the link to making 12 trefoil knots:

Biagio, your website is quite interesting, about synergetic geodesics and also the music.
I seem to enjoy the triaxial weaving more than the lumber & steel connections (conceptually), it is smoother, simpler and less angular/planar.
