Every concerned educator, he suggests, must develop the necessary skills and understandings to operate as a skilled consumer of proposed ideas for change in education. He offers practical guidelines

Quasi-logarithmic spacing law in dewetting patterns from the drying meniscus of a polymer solution

We report on a periodic precipitation pattern emerged from a drying meniscus via evaporation of a polystyrene solution in a Petri dish. It appeared a quasi-logarithmic spacing relation in the pattern as a result of stick-slip motion of the contact line towards the wall. A model based on the dynamics of the evaporating meniscus is proposed
