Research interests: Holistic worldview
Nature is rich but not random in its diversity. Also complexity of nature is astounding but not arbitrary. We do recognize rules and regularities that we know as laws of physics and chemistry, or those that we refer to as relations in biology, economics, behavioral and social sciences. Disciplinary canons are not disconnected from each other but relate via ubiquitous characteristics of nature. These are skewed distributions that accumulate along sigmoid growth and decline curves which in turn display mostly as straight lines on log-log plots, i.e., follow power laws.
The principle of least action was early on thought of as a powerful way to make sense of various complex phenomena as well as of simple matters. It says that a difference in energy of any kind will level off in least time. The naturalistic tenet assigns energy to everything that exists, and describes all processes as least-time consumption of free energy. The natural principle in the form of an equation of motion reveals that evolution is inherently an intractable, path-dependent process.
Science by submerging to specialties supplies us with detailed information whereas by recognizing universalities it provides us with thorough comprehension. Indeed, as our delusions of uniqueness have narrowed, our worldview has widened toward entirety.
