Jody Harrison (HeraldScotland)THEY are among the most mysterious artefacts ever discovered in Scotland, ornate relics whose purpose has long been lost to the mists of time.

Jody Harrison (HeraldScotland)I AM pleased that Jeff Nisbet has managed to do what I have tried in vain to do for the past two years which is to get media interest into what may well be the first examples of art in Scotland ("New theory sheds light on mysterious stone balls found across Scotland", The Herald, May 4) with the suggestion that the balls are, perhaps, apprenticeship pieces for entry into the profession of stone masonry.
Hugh Newman investigates the geometric stone spheres found in Northeast Scotland, Orkney and parts of Britain and Ireland. What were they used for? How did they carve them? One was even found in Bolivia! Read Hugh's two-part article here: https://bit.ly/2H9YxU4.
This has some interesting basic facts and discussion, but it also suggests some complete bunk science and ideas like “energies” and “healing” which are far less likely. I’m not sure I can get behind any of the mathematical ideas.
Our archaeological art takes its inspiration from artefacts found in Orkney. Each one is a unique piece, made by archaeologist Chris Gee.
In the long summer evenings, when it hardly gets dark at all here in Orkney, you will often find Chris in his garden overlooking the archipelago, where he is chipping away at another stone. He finds delight in recreating Stone Age art using their tools and methods. And like them, he carefully selects local stone, with beautiful colours and patterns. In this way, he makes Neolithic ceremonial maces, stone axes, carved stone balls, enigmatic carved stone objects, and beautifully patterned sandstone which he sometimes colours with hematite and other natural dyes. It is awe-inspiring to think that his hands are recreating the same movements that someone right here in Orkney did more than five thousand years ago.
Archaeologist Chris Gee shows how he makes a Carved Stone Ball as they did in Neolithic times. Chris is from the Orkney Islands in Scotland and makes Neolithic art by hand, using the same methods as people would have done in Orkney 5000 years ago.

Neil Wilkin is back with another bronze age adventure. In this episode he is joined by Susan Greaney, Senior Properties Historian for English Heritage to discuss the history and importance of Stonehenge. Going into the heart of the monument and looking at some related bronze age objects Neil and Susan explore the connections between Stonehenge, the rest of Britain and the continent.

Prehistoric Petrosphere – Carved Stone Spheres and Balls Prehistoric Petrosphere – Carved Stone Balls are spherical human-made objects made from stone. These ancient artifacts have been created by carving by up to up to 5200 years ago. These carved stone balls dating from the Late Neolithic to as late as the Iron Age, are mainly […]
Plotting the find sites on a map shows that these petrospheres were often located in the vicinity of Neolithic recumbent stone circles. ❧

They are usually round of reasonably uniform size at around 2.75 inches or 7 cm across. They can have from 3 to 160 protruding knob shapes on the surface. These carved stone balls are nearly all have been found in north-east Scotland, the majority in Aberdeenshire. As portable objects, they are straightforward to transport and have been found on Iona, Skye, Harris, Uist, Lewis, Arran, Hawick, Wigtownshire, and fifteen from Orkney. A similar distribution to that of Pictish symbols led to the early suggestion that carved stone balls are Pictish artifacts. However, examples have been found in Ireland and England. ❧

I’m curious if they were following the recent functionality added by ThreadReaderApp using Micropub? I’m guessing the fact that they used the verb “unroll” means they were at least aware of it as a functionality.

I’ve always loved OPML subscription: you follow an OPML source that automatically updates your feed over time. Sadly @inoreader is one of the few apps that supports it.
Category theory is unmatched in its ability to organize and layer abstractions and to find commonalities between structures of all sorts. No longer the exclusive preserve of pure mathematicians, it is now proving itself to be a powerful tool in science, informatics, and industry. By facilitating communication between communities and building rigorous bridges between disparate worlds, applied category theory has the potential to be a major organizing force. This book offers a self-contained tour of applied category theory. Each chapter follows a single thread motivated by a real-world application and discussed with category-theoretic tools. We see data migration as an adjoint functor, electrical circuits in terms of monoidal categories and operads, and collaborative design via enriched profunctors. All the relevant category theory, from simple to sophisticated, is introduced in an accessible way with many examples and exercises, making this an ideal guide even for those without experience of university-level mathematics.
