## String Theory

In 1906, Caroline Furness Jayne wrote String Figures And How To Make Them - A Study Of Cat's Cradle In Many Lands [Google Books], probably the best-known study of string figures and string games.

## Talking fast and making cool videos does not mean learning is happening

So you're me and you're in math class and you're learning about graph theory, a subject too interesting to be included in most grade school's curricula so maybe you're in some special program or maybe you're in college and were somehow not scarred for life by your grade school math teachers.

## Borromean Rings and Quantum Mechanics

Borromean rings consist of three circles linked as a group, with no two circles interlinked; removal of one ring results in the separation of all three. Named for the Borromeo family of 15th century Italy which featured the rings on its coat of arms, the symbol has had a long and varied history. The rings have appeared everywhere from medieval Christian iconography to Norse rune stones to the pillars of Hindu temples. In more recent times, Borromean rings have attracted formal study in the fields of topology, chemistry and (strangely enough) quantum mechanics.

## Knots and Crosses

Sure, knot theory is an interesting subject with a storied past, and self-avoiding walk theory takes it a bit further in describing real-world ropes, lines and wires, but can it be usefully applied to the knotty problem of spontaneously forming tangles? Robert Matthews of Aston University has suggested that there's a simple solution to avoiding tangles in all our computer cables, headphone cords and Vectran cored double braid halyard lines: make them into loops [pdf]. It's plausible, but not proven. Enter The Great British Knot Experiment which aims to provide "compelling empirical evidence to support the Loop Conjecture – and thus for its role in solving one of life's little irritations."
