It's a remarkable fact that matter at the subatomic level consists of tiny chunks, with vast empty spaces in between. Even more remarkable, these tiny chunks come in a small number of different types (electrons, protons, neutrons, pi me-so...
متن کاملVisuoperceptual functioning differs in 9- to 12-year olds prenatally exposed to cigarettes and marihuana.
Visuoperceptual performance was examined in 146 9- to 12-year old children for whom prenatal exposure to marihuana and cigarettes had been ascertained.
