(1990). "Foundations of Economics." Hebrew.

Foundations of Economics

Abstract: This book proposes a new way to explain and forecast economic processes. We know that forecasting in a conservative system may be done well (just like in energy and weather systems, the more closed the system, the better the forecasting). An autonomous economic system (i.e., a country) is a conservative system in Keynes space, defined as an output-money space (i.e., a market).



(1995). "Dynamic Economy." Hebrew.

Dynamic Economy

Abstract: A conservative system in which rates are linearly related is a symmetric system. Symmetry dictates that the inflation rate equals the money-printing rate minus the growth rate. An empirical study of 45 countries between the years 1960 and 1993 verifies the principles of both conservation and symmetry. Tamari's theories enable good economic forecasting through formulating 'motion equations' (derived from the Lagrangian function) and their solutions (Lorentz transformations), based on the conservation and symmetry principles as described in his books.



(1997). "Conservation and Symmetry Laws and Stabilization Programs in Economics." English.

Conservation and Symmetry Laws and Stabilization Programs in Economics

Abstract: An autonomous economic system, i.e., a country, tends to be a conservative and a symmetrical system in Keynes space (Output, Money and Time [Ot, Mt ; t]), and can therefore be represented as a complex numbers system. This presentation makes it possible to aggregate (or disaggregate) the system at all levels, from the individual to the most general aggregate (and vice versa). It also offers a simultaneous solution to the problem of allocating and distributing useful resources in the market.




(2005). "Eco - Economic Simulator." softwaree.

Tamari attractor

Abstract: Eco - Economic Simulator software - an application of the Tamari attractor - enables the study of a country's economy. The software performs a simulation of the country's economy: analysis, planning, prediction and comparison with other nations' economies, based on data in International Financial Statistics (IMF) for the years 1960-2011 for 26 select countries.

My Fragments - From My Personal Point of View - The Complete List:


MF1:  Fractals relate to attractors like cobblestones in roads.   Added 1 January 2000.


MF2:  The Pythagorean Theorem: a2 + b2 = c2 is the seed;  Einstein's Formula: E = MC2 is the tree.
                 In the spirit of Friedrichs (1965). "From Pythagoras to Einstein," MAA.   Added 10 July 2000.


MF3:   Fractalization of the Language I.   Added 21 April 2002.

A word is worth a thousand ...?

"A picture is worth a thousand words," as the old saying goes,  Mathematica and Politica                                 
     but sometimes: One good sentence is worth a thousand pictures.
     For example: "A picture is worth a thousand words" (like a Mobius strip).

A metaphor is worth a thousand pictures.

An allegory is worth a thousand metaphors.

A ? is worth a thousand allegories.



MF4:  Evolution of form is birth and death, construction and destruction, trial and error  ... 
             forever, but accompanied by a self-correcting mechanism/feedback.  
Added 1 January 2003.


MF5:  The clever know the past - the wise understand the future.   Added 30 April 2007.


MF6:  Consumption and publication are physical and mental pollutions - avoid them.   Added 30 April 2007.


MF7:   Globalization + Computerization = Tsunamization.   Added 9 October 2008.

MF9:  Fractals and chaos is like sewing and cooking.   Added 28 March 2009.


MF10:   Fractalization of the Language II.   Added 15 November 2009.

"Between any two 'points' in a set of points" or numbers, words, sentences, paragraphs, thoughts, etc.,
"we can put another point" or numbers, words, sentences, paragraphs, thoughts, etc.,
and if the set is not big enough, we can add another 'point.'

Georg Cantor and Kurt Gödel used this to prove their theorems. Of course, the trick is not just to add another 'point,' numbers, words, sentences, paragraphs, thoughts, etc., but to find a new one.

Wislawa Szymborska (2005) "Colon": "The nightmare of the poet" (trans. by Deena Land, 15 July 2010)

"An allocated number of words. Never a needless one.
Meaning - no poetry.

MF14:  Mathematics is a simple way to say the complicated and poetry is a complicated way to say the simple.  Added 10 August 2010.


MF15:  Poetry is dreaming while awake.   Added 10 August 2010.


MF16:   Life is an infinite/impossible mission;  death is a finite/possible mission.
               For God/Nature it is the other way around.  
Added 10 August 2010.

MF19:  He who takes the high road reaches far.    Added 14 October 2011 


MF20:  Words are clouds and mathematics is the rain.    Added 12 March 2012.

MF22:  When the money illusion stops, Gresham's Law start to operate.   Added 28 July 2014.

Ben's Photos

The painter Mark Rothko said: "The only thing I care about is the expression of man's basic emotions..."

In the same spirit, I try to express mood in my pictures.
