Knowledge comes to us through observations. This is in its basic form a binary process. The neurophysiological equivalent is the action potential, which can be facilitated or inhibited, recursive and summated but still a binary process. This article tries to reformulate relativistic gravity and kinetic energy to fit the binomial model. With the function f(x)=(1/x) and the inverse of the derivative of the Lorentz transformation, both Einsteinian kinetic energy and relativistic gravity can be computed with correct values. With the constants c and G, it is possible to construct a version of postnewtonian relativistic gravity, consistent with basic parts of Einstein's theory, but also suggesting a calculation of the expanding universe, deduction of a correct value of the Hubble constant, with no other constants involved than c and G. The binomial model with covariance/correlation is discussed and then tried in a formulation of the double-slit experiment, Bell's inequality and Heisenberg's uncertainty. In this variance is what describes potential of observation, which is often the case for the action potential in neurophysiology. Finally an attempt is made to fit the reformulation of kinetic energy and gravity in the binomial model.
