Kinetic exchange models: From molecular physics to social science

Visual thinking in discovery and invention: From physics to cognitive social science

This talk will discuss the role of visual thinking in scientific discovery and technological invention. Visual thinking uses picture-like representations as internal mental models or as external depictions such as diagrams. The first part of the talk will analyze the role of visual thinking in 100 great discoveries and 100 great inventions. The second part will discuss the contribution of visua...

Molecular Electronics: from Physics to Computing

Even if Moore’s Law continues to hold, it will take about 250 years to fill the performance gap between present-day computer and the ultimate computer determined from the laws of physics alone. Information processing technology in the post-CMOS era will likely consist of a heterogeneous set of novel device technologies that span a broad range of materials, operational principles, data represent...

From Physics to Algorithms: New Approaches to Information Science

From continuum Fokker-Planck models to discrete kinetic models.

Two theoretical formalisms are widely used in modeling mechanochemical systems such as protein motors: continuum Fokker-Planck models and discrete kinetic models. Both have advantages and disadvantages. Here we present a "finite volume" procedure to solve Fokker-Planck equations. The procedure relates the continuum equations to a discrete mechanochemical kinetic model while retaining many of th...

Kinetic exchange models for income and wealth distributions

Increasingly, a huge amount of statistics have been gathered which clearly indicates that income and wealth distributions in various countries or societies follow a robust pattern, close to the Gibbs distribution of energy in an ideal gas in equilibrium. However, it also deviates in the low income and more significantly for the high income ranges. Application of physics models provides illumina...
