This is based on experience and contacts with numerous science educators who have been concerned with “HAVE NOT” (less advantaged/disadvantaged/socially, culturally, and economically different) students around the world. I conclude that recent curricular efforts in science and technology education offer no solutions for these students. The failure is partly due to the structure of the present s...

Suppose the auto-correlations of real-valued, centered Gaussian process Z(·) are non-negative and decay as ρ(|s − t |) for some ρ(·) regularly varying at infinity of order −α ∈ [−1, 0). With Iρ(t) = ∫ t 0 ρ(s)ds its primitive, we show that the persistence probabilities decay rate of − logP(supt∈[0,T ]{Z(t)} < 0) is precisely of order (T/Iρ(T )) log Iρ(T ), thereby closing the gap between the lo...

The use of different probability distributions as described by the Exponential, Pareto, Lognormal, Rayleigh, and Gama probability functions applied to estimation the time of the next great earthquake (Ms≥6.0) in different seismotectonic provinces of Iran. This prediction is based on the information about past earthquake occurrences in the given region and the basic assumption that future seismi...
