The final truth about a phenomenon resides in the mathematical description of it; so long as there is no imperfection in this, our knowledge of the phenomenon is complete. We go beyond the mathematical formula at our own risk; we may find a model or a picture which helps us understand it, but we have no right to expect this, and our failure to find such a model or picture need not indicate that either our reasoning or our knowledge is at fault. The making of models or pictures to explain mathematical formulas and the phenomena they describe is not a step towards, but a step away from reality; it is like making a graven image of a spirit.

We are frequently faced with the necessity of looking for the picture required for the visualization of an object, not in the perception of this particular object, but in a different perceptual image. ...we can assert the discrepancy between the perceived picture and the objective state. This discrepancy... proves absolutely nothing against the fact that all visualizations are merely sense qualities of the perceptual space. ...If the parallelism is ...to be visualized, we must supplement our assertion by the description of certain qualities with which we are familiar from perceptual space.

León Krauze: I am sure that you know about this topic: various leftist governments, especially the populists, are in serious trouble in Latin America. The socialist model in Venezuela has the country near collapse. Argentina, also Brazil, how do you explain that failure?
Bernie Sanders: You are asking me questions...
Krauze: I am sure you're interested in that.
Sanders: I am very interested, but right now I'm running for President of the United States.
Krauze: So you don't have an opinion about the crisis in Venezuela?
Sanders: Of course I have an opinion, but as I said, I'm focused on my campaign.

In this book I try to show how models of self-organization can be applied to many economic phenomena - how the principle of "order from instability," which explains the growth of hurricanes and embryos, can also explain the formation of cities and business cycles; how the principle of "order from random growth" can explain the strangely simple rules that describe the sizes of earth quakes, meteorites, and metropolitan areas. I believe that the ideas of self-organization theory can add substantially to our understanding of the economy; whatever their ultimate usefulness, these ideas are very exciting, and playing around with them is tremendous fun.

Heisenberg finds that facts of observation lead uniquely and inevitably to the theoretical structure known as matrix mechanics. This shows that the total radiation in any region of empty space can change only by a single complete quantum at a time. Thus not only in the photo-electric phenomenon, but in all other transfers of energy through space, energy is always transferred by complete quanta; fractions of a quantum can never occur. This brings atomicity into our picture of radiation just as definitely as the discovery of the electron and its standard charge brought atomicity into our picture of matter and of electricity.

On those rare occasions when a great motion picture reaches multiplexes, the film critic must add another aspect to his or her job description: that of cheerleader. It is incumbent upon those of us who routinely dissect movies to applaud the arrival of something like Minority Report. Writing a review isn't enough - we have to get out there and actively stump for the movie. The underlying reason is sound: if Minority Report makes a lot of money, the studios will be encouraged to fashion more films of this sort. And that is a good thing - not just for science fiction lovers but for fans of intelligent, thought-provoking pictures of all genres.
