A Noosphere diagram is a type of pie chart based on the noosphere concept, developed by Vladimir Vernadsky, Édouard Le Roy and Pierre Teilhard de Chardin in the twentieth century. The diagram illustrates an individual’s knowledge, broken down by discipline and level. It allows individuals to log all productive hours and keep an on-going record of personal knowledge development (quantified your self).

The diagram takes a pie chart structure; each slice represents a field of knowledge and corresponds with the International Standard Classification of Education, ISCED-F 2013, as set by Unesco.
The pie chart is formed of eight concentric circles, each of which corresponds with the ISCED 2011 – a Unesco classification - and represents the level of knowledge from basic childhood knowledge of literacy (ISCED 0), numeracy and communication through to PhD and the creation of new knowledge (ISCED 8).
The Noosphere diagram combines the pie chart slices representing fields of knowledge with the concentric circle system denoting level of expertise. Each segment resulting from the intersection represents a certain level of knowledge in a particular field.
The Noosphere diagram uses the European Credit Transfer and Accumulation System (ECTS), which defines how much study time is required in order to complete each level of education. This Noosphere diagram below shows a Bachelor degree in Law, which requires 4,500 hours of study according to ECTS. Using this formula, the Noosphere diagram is able to calculate the time requirement to acquire all human knowledge taught in formal education; 168 years of uninterrupted learning.
Different categories of time
Each intersecting segment between concentric circle and slice is divided into three parts that represent the type of time devoted to developing this knowledge. The first category represents time spent studying new knowledge or skills; the second category corresponds with time spent practising or doing; the third segment shows the time spent teaching.

The Noosphere diagram can be used to track individual development, creating a pictorial
representation of individual knowledge and allowing people to constantly monitor and update
The diagram has a wide range of applications; it can be used by job-seekers wishing to represent their skills, knowledge and competences in a visual manner, by employers seeking professionals with a particular skill set and background or by education providers looking for students that meet certain criteria.
The first known use of concept of this type was developed in the twentieth century by
Vladimir Verdansky. Édouard Le Roy and Pierre Teilhard de Chardin. Denoting human cognition,
it was the third phase of development of the Earth, following the geosphere – inanimate
matter – and the biosphere – biological life.
Updated in the twenty-first century Roman Tarabrin and Company 73 Ltd., the Noosphere diagram now provides a complex breakdown of individual fields of knowledge and level of expertise. The development of classification systems such as ISCED-F and the European Qualifications framework have enabled the international application of the Noosphere diagram.
