How Complex is the Ulam Spiral?
How Complex is the Ulam Spiral?
From Wikipedia: “The Ulam spiral, or prime spiral (in other languages also called the Ulam Cloth) is a simple method of visualizing the prime numbers that reveals the apparent tendency of certain quadratic polynomials to generate unusually large numbers of primes. It was discovered by the mathematician Stanislaw Ulam in 1963…”
How complex is it? Here goes the Complexity Map of the above image:

Why Has Our Ability To Engineer Complex Products Dimished?
Why Has Our Ability To Engineer Complex Products Dimished?
The complexity of modern products, as well as the associated manufacturing processes, has increased over the past few decades and there is evidence the trend will continue. Complexity means functionality. Consider how many things can be done with smartphones, in addition to making phone calls. Think of automobiles, which can maintain a constant distance from the car in front, or engage emergency…

The Principle of Ignorance
The Principle of Ignorance
The Principle of Ignorance is a ‘corollary’ of the Principle of Fragility, which states:
Complexity X Uncertainty = Fragility
This principle states that highly complex actions (or business models) lead to situations of fragility in uncertain environments (e.g. markets). For example, a highly articulated portfolio may result to be fragile in a turbulent market. In effect, the more an…

Optimum-Complexity Portfolios: How to Invest in Turbulent Times
Optimum-Complexity Portfolios: How to Invest in Turbulent Times
Research confirms that high portfolio complexity impacts negatively mid and long-term expected returns. This is because high complexity is a formidable source of fragility, hence vulnerability. In a turbulent economy highly vulnerable portfolios and financial products are more exposed and more volatile. Therefore, a new portfolio design strategy based on complexity has recently been developed.…

Ontonix Runs the Largest Complexity Group in Linkedin
Ontonix Runs the Largest Complexity Group in Linkedin
One of the oldest groups dedicated to complexity, our Linkedin group is also the largest, with over 1600 members. But what distinguishes our group is that it is dedicated to a quantitative approach to complexity. In our group we discuss the properties of complexity as well as its applications not by talking about but by measuring it. Science, not opinions.
It is truly amazing to witness how…

Sustainability - New Quantitative Approaches, New Indices
Sustainability – New Quantitative Approaches, New Indices
Sustainability is a popular subject nowadays Sustainability implies permanence, a sort of steady-state, almost some kind of equilibrium. However, in today’s world, speaking of permanence or steady state is a contradiction to say the least. From an energetic-thermodynamic standpoint a system or a process is sustainable if there is sufficient long-term energy supply to keep it running (possibly…

When did the "Liquid Society" Start?
When did the “Liquid Society” Start?
“Liquidity” by Lorenzo Genetti, January 2015, Mar del Plata, Argentina.
The characterization of modernity as a “liquid time” is one of the greatest successes of contemporary sociology. The term, coined by the Polish sociologist Zygmunt Bauman, realizes precisely the transition from a “solid” -stable, repetitive to a ‘liquid’ -flexible, voluble- modernity in which social structures no longer…

What is 'Ontonix'?
What is ‘Ontonix’?
Ontology, existence, being, reality
31-st December, 2014
As our company celebrates this month ten years of activity, it seems fitting to answer, in this year’s last blog entry, the question I am frequently asked: what does ‘ontonix’ mean?
Ontonix comes from ‘ontology’. Ontology is the philosophical study of the nature of being, becoming, existence, or reality, as well as the basic categories of…
