Why ICT Systems Implode

  Remember the recent British Airways IT meltdown? Problems with power supply are believed to have caused the problem. Note the word “believed”. According to the mentioned source, when the system came back online, it did so in an uncontrolled manner, damaging the IT system and initiating a sequence of events that plunged the system…

Stop Pretending that an Economy Can Be Controlled

We reproduce verbatim a very interesting article by Angel Gurría, OECD Secretary-General. All our blogs are original, with very minor exceptions. This is one of those exceptions. An exceptional article: “The recent financial crisis exposed some serious flaws in our economic thinking. It has highlighted the need to look at economic policy with more critical,…

The Complexity Map of the Human DNA. Is it possible?

The human genome contains 20000-25000 genes (3 billion letters). The approximate number of atoms necessary to encode human DNA is 200 billion. For example, Thymine’s base is a pyrimidine ring compound and it contains 15 atoms. Its pentose sugar has 15 atoms also (the 5-carbon sugar used for ribonucleic acid (RNA) is very similar, but…

Gravity, Time and Complexity

In a recent article entitled “Is gravity the force driving time forwards”, a new theory is proposed in order to explain why time evolves only in one direction. The theory attempts to complement the Second Law of Thermodynamics, which has been instrumental in terms of establishing the concept of arrow of time based on entropy.…

A Bank in a Nutshell

Businesses rely heavily on information and data. Many businesses actually store data. Some businesses use this data to derive statistics and models which are then used in an attempt to make the business more profitable, more efficient and streamlined. In other cases, models are used to produce forecasts, improve resource allocation, perform scenario analysis or…

Autonomous Driving. Are we Ready?

In highly complex systems malfunctioning or even bad design may remain invisible for a long time. In highly complex systems the crucial variables are often discovered by accident. Highly complex systems cannot be designed without taking complexity into account. Sounds obvious but today, in engineering design complexity is not considered as an attribute of a…
