Smale – Fomenko diagrams and rough topological invariants of the Kowalevski – Yehia case

image

Kharlamov and Ryabov introduce their paper by stating:

We present the complete analytical classification of the atoms arising at the critical points of rank 1 of the Kowalevski–Yehia gyrostat. To classify the Smale–Fomenko diagrams, all separating values of the gyrostatic momentum are found. We present a kind of constructor of the Fomenko graphs; its application gives the complete description of the rough topology of this integrable case. It is proved that there exists exactly nine groups of identical molecules (not considering the marks). These groups contain 22 stable types of graphs and 6 unstable ones with respect to the number of critical circles on the critical levels.

Assuming that went over your head like it went over mine, it has something to do with what CERN does (studying particle physics). Any simple explanation in the comments would be greatly appreciated.

Eye Magazine Interview with Karsten Schmidt

JLW: Is coding design?

KS: It’s funny how the moment you start talking about code, you start being   into a technical role. Because so many people are alienated. They know they don’t understand … but they want to protect their status as a ‘creative’.

When you work with code, actually typing code is absolutely the last thing you think about … writing code becomes a background task, because you’re actually building a mental model of what you want to do. This is what makes code work. This is where you work as a designer. Mapping is what we all do automatically, but for code it has to become a conscious act.

JLW: When you’re designing something?

KS: Yes – even when you do a poster. You have a mental image and that image doesn’t pop into your head. You really focus on it, you have to analyse what happens and you have to break this process down into such small parts that it becomes encodable as code.

JLW: So is there an argument that some computer programs take away these mental tools?

KS: Well there’s something I said at Flash On The Beach in Brighton – that Kenneth Boulding quote: ‘We make our own tools, and then they shape us.’ If you depend too much upon any tool – Flash or whatever – sooner or later your idea will be channelled through that tool’s metaphors, and there goes your idea!

Anthropological Diagrams

Up until now, SciGraph has been focused almost entirely on images from the mathematical, life and physical sciences. This post, however, features diagrams from the field of anthropology.
