Climate change is a vortical situation of increasing turbulent conditions called the “sixth extinction.” In this chapter I begin with the two-dimensional Archimedean spiral (the coiling rope), move on to the three-dimensional corkscrew spiral (or threaded screw), and on to the three-dimensional double spiral of upward and descending movement with many nested vortices. The latter is more necessary to understand climate change, and our possible future in it, than the flat spirals. Ironically, Plato wrote about the double-twisted spiral with its nested vortices long ago. We are in a double-spiralic helice, a vortical phenomenon with centripetal and centrifugal, upward-ascending and downward-descending waves, and left and right turning whorls. It is worse than this. We need to challenge spiral symmetry thinking. There is no reality axis around which the spiralic helice is spinning, and there is no symmetry. There is no uniformity to the spiralic vortices of turbulence of the sixth extinction.

Purpose – To discover and unravel the contribution of women to innovation and invention. This chapter builds upon a book published in 2003, called, Ingenious Women. The purpose of the book was to discover the invisible women inventors and patent holders operating between 1637, when the first patent was awarded to a woman, and the outbreak of war in 1914. For the purpose of this essay, the time frame has been extended to the present.

Methodology – Historical patents are used as the main research base, supported by searches of other relevant databases, directories and specialist archives (census records, registered designs, company records, museum collections) as well as specialist literature.

Findings – The research illustrates that women and men were often part of a wide network of discoverers and innovators and were able, by using the latest technologies and materials available, to resolve problems both large and small.

Research limitations/implications – This categorisation on patent databases or directories and searches were by female first names or by object type. his categorisation highlights the historical assumption that women are not inventors. Although this search method highlighted hundreds of women, there must be many still undiscovered.

Practical implications – Not all the ideas went into production and some have now become obsolete. Others continue to be produced and have formed the basis of successful companies. Many women became entrepreneurs and developed businesses based on their inventions and some, as widows, successfully ran their deceased husbands' companies.

Social implication – The women in this hidden history often had to navigate a path through social attitudes and legislative frameworks. They are all an example to women today that anyone, regardless of gender, can be innovative and entrepreneurial. What is crucial is that the ideas being developed are unique and have a purpose.

Human beings spend their daily lives within the range of the atmospheric boundary layer, where airflow is affected by friction from Earth's surface. The airflow in this area is generally called wind. Strong wind occasionally causes severe damage to infrastructures and people because of its aerodynamic effects, but even weak and moderate winds can have serious environmental impacts on human society such as those seen with air-pollution problems and thermal effects.

Certain elements of Hayek’s work are prominent precursors to the modern field of complex adaptive systems, including his ideas on spontaneous order, his focus on market processes, his contrast between designing and gardening, and his own framing of complex systems. Conceptually, he was well ahead of his time, prescient in his formulation of novel ways to think about economies and societies. Technically, the fact that he did not mathematically formalize most of the notions he developed makes his insights hard to incorporate unambiguously into models. However, because so much of his work is divorced from the simplistic models proffered by early mathematical economics, it stands as fertile ground for complex systems researchers today. I suggest that Austrian economists can create a progressive research program by building models of these Hayekian ideas, and thereby gain traction within the economics profession. Instead of mathematical models the suite of techniques and tools known as agent-based computing seems particularly well-suited to addressing traditional Austrian topics like money, business cycles, coordination, market processes, and so on, while staying faithful to the methodological individualism and bottom-up perspective that underpin the entire school of thought.

Arnold Arons, along with Robert Karplus, can fairly be called one of the founding fathers of U.S. Physics Education Research and a pioneer of inquiry methods of education. The instructional methods advocated by Arons were influenced by the work of Socrates, Plato, Montaigne, Rousseau, Dewey, Whitehead, and Piaget, but are primarily derived from Arons’ epic half century effort to improve introductory science teaching by shutting up and listening carefully to students’ responses to probing Socratic questions on physics, science, and ways of thinking. Arons emphasized: (1) conceptual understanding, (2) operative knowledge, (3) interactive engagement, (4) Socratic dialogue, (5) attention to cognitive development, (6) attention to preconceptions of beginning students, (7) operational definitions, (8) reduction of volume and pace of standard introductory courses, (9) idea first, name afterward, (10) importance of a course “story line,” and (11) science as a liberal art. Most of these are attributes of enlightened inquiry-based learning as described in Inquiry and the National Science Education Standards: A Guide for Teaching and Learning (NRC, 2000).

Purpose – The aim of this study is to determine the differences in the antimicrobial activity of katuk leaf (Sauropus androgynus (L.) Merr) against Escherichia coli.

Design/Methodology/Approach – The method used in this study was experimental posttest using a control group design. Analysis of the effect of katuk leaf was performed in the dilution method with 20%, 40%, 60%, 80%, and 100% concentration. The data were analyzed using one-way ANOVA test (α = 0.05) and was then tested using the least significant difference (LSD) test.

Findings – Bacterial colony counting that used total plant count found the average of E. coli amount at 20% of concentration (526.820 CFU/ml), 40% of concentration (449.380 CFU/ml), concentration of 60% (255.710 CFU/ml), concentration of 80% (194.110 CFU/ml), and at concentration 100% (168.600 CFU/ml). This study concluded that the katuk leaf extract at 20%, 40%, 60%, 80%, and 100% of concentration had antimicroba effect with significant influence. The 100% of concentration had the most significant effect compared with the other concentrations.

Research Limitations/Implications – Katuk leaf could be used as one of the alternative herbal choices that has a compound antimicrobial effect.

Originality/Value – This study increases the theoretical understanding of the difference of antimicrobial effectivity of katuk leaf extract (S. Androgynus (L.) Merr.) concentration against E. coli
