A Theoretical Treatment of Memetic Traits Using Gene-Meme, Meme-Meme and Population Equilibrium (preprint -, Jan. 2021)
This paper analyzes equilibrium between gene-meme and meme-meme competing propagators and consider whether a meme is linked to reproduction (e.g. vertical culture transmission), or not. We employ a genetic component and combined meme induced fitness components for hosts, while memes have replication factors to distinguish from what's good for the host (fitness).

Partial Unlock for COVID-19-Like Epidemics Can Save 1 - 3 Million Lives Worldwide (Open Journal of Epidemiology, Vol.10 No.3, August 2020, DOI: 10.4236/ojepi.2020.103024) A large percentage of deaths in an epidemic or pandemic can be due to overshoot of population (herd) immunity, either from the initial peak or from planned or unplanned exit from lockdown or social distancing conditions. We study partial unlock or reopening interaction with seasonal effects in a managed epidemic to quantify overshoot effects on small and large unlock steps and discover robust strategies for reducing overshoot.

Wealth-relative effects in cooperation games (J. Heliyon, 5, 12, Dec. 2019) This paper investigates cooperation games in which poor agents do not benefit from cooperation with wealthy agents. They instead benefit from considering wealth relative to decision payoffs of fitness or wealth.

Wealth inhomogeneity applied to crash rate theory (J.Heliyon, 1, 3, Nov 2015) - A crash rate theory based on corporate economic utility maximization is applied to individual behavior in U.S. and German motorway death rates, by using wealth inhomogeneity data in ten-percentile bins to account for variations of utility maximization in the population.

A family of metric gravities With a new exact Schwarzschild method, a local space-time relation, strong-field verification targets, and the ability to promote field gravities to full metricity (The European Physical Journal Plus, 133: 158, April 2018) The goal of this paper is to take a completely fresh approach to metric gravity, in which the metric principle is strictly adhered to but its properties in local space-time are derived from conservation principles, not inferred from a global field equation.

Entropy-Like State Counting Leads to Human Readable Four Color Map Theorem Proof (Pure and Applied Mathematics Journal. Vol. 7, No. 3, 2018, pp. 37-44. doi: 10.11648/j.pamj.20180703.12) The problem of how many colors are required for a planar map has been used as a focal point for discussions of the limits of human direct understanding vs. automated methods. It is important to continue to investigate until it is convincingly proved map coloration is an exemplary irreducible problem or until it is reduced. Meanwhile a new way of thinking about surfaces which hide N-dimensional volumes has arisen in physics employing entropy and the holographic principle. In this paper we define coloration entropy or flexibility as a count of the possible distinct colorations of a map (planar graph), and show how a guaranteed minimum coloration flexibility changes based on additions at a boundary of the map.

Numerical Geodesic Approximation for Theoretical and Experimental Light Bending Analysis (Advances in Astrophysics, vol 2, no 1, pp 76-85, August 2016)  This paper investigates a least-time (or fastest-path) two-point algorithm for numerically propagating a light ray in a gravitational field using anisotropic coordinate velocity and distant observer coordinates. Rather than imaging or ray tracing, the objective is to support analysis of fundamentals and to be able to find null geodesics in arbitrary metrics.

Common pedagogical issues with de Broglie waves: moving double slits, composite mass and clock synchronization (Shuler, R.L., "Common Pedagogical Issues with De Broglie Waves: Moving Double Slits, Composite Mass, and Clock Synchronization," Physics Research International, Vol. 2015 (2015). - direct link to PDF)This pedagogical paper suggests simple techniques for reference frame independent analysis of a moving double slit electron interference experiment, and a beat frequency heuristic for understanding de Broglie waves of composite particles such as neutrons and atoms.

Leading Clocks Lag Phys. Ed., 51, 2 (2016) - A new memory aid for teaching the relativity of simultaneity is given that puts it on a par with "time dilation" and "length contraction" for quick and easy problem visualization.

The Twins-Clock Paradox History and Perspectives - (Journal of Modern Physics, July 2014 DOI: 10.4236/jmp.2014.512108) - The twins or clock paradox has been a subject of lively discussion and occasional disagreement among both relativists and the public for over 100 years, and continues to attract physicists who write papers giving new analyses or defending old ones, even though many physicists now consider the matter only of educational interest.  (Our most popular paper with 5390 downloads!)

A Fresh Spin on Newton's Bucket - (Published version in Physics Education vol. 50 no. 1 p. 88, 2015, short illustrated article suitable for high school or first semester physics students)  An introduction to physics seems incomplete without the thought experiment known as Newton's Bucket.  Doing so also introduces the famous historical critique of Newton by Mach, which inspired Einstein and spawned modern theories of gravity and the cosmos.

Who We Are . . .

Robert Shuler about:  He is the author of over 50 peer reviewed technical papers, a book on Crash Rate Theory and two books on economics.  He is retired from a 45 year career in advanced projects and systems reliability at NASA and continues select areas of research related to the future of society.  He lives in Texas most of the time, likes to visit his wife's relatives in Siberia, and publishes music arrangements

Theo Koukouvitis about:   With thousands of published articles and dozens of eBooks that between them command millions of daily views, I am one of the most prolific and successful freelance writers active today.

Civille O. Brown, MLS, about:  I am interested in how each person's unique talent, experience and life situation leads them to different choices, and how to maximize each person's potential.  According to evolutionary theory, there is no progress or advancement of one over the other, we've all been here 3.5 billion years.  But the future can be predicted sometimes, and knowing it changes it.  Then progress can be defined by a combination of the individual desires and abilities relative to the future environment.  Getting along in a common world does not mean we all want to behave in the same way or seek the same things.  "Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid," wasn't really said by Einstein, but it sums up my approach to the study of people.

Dyske Suematsu about:  I help small business owners leverage the power of the Internet to grow their business. I have breathed and lived on the Internet for the past 20 years, and, therefore, have a good sense of how things evolve—what works and what doesn’t. I can learn my clients’ business objectives, provide actionable strategies, and manage the execution.
