The generation of droplets at low Reynolds numbers is driven by nonlinear dynamics that give rise to complex patterns concerning both the droplet-to-droplet spacing and the individual droplet sizes. Here we demonstrate an experimental system in which a time-varying energy landscape provides a periodic magnetic force that generates an array of droplets from an immiscible mixture of ferrofluid an...

Four-year-olds were tested for their ability to use differences in the spacing among features to recognize familiar faces. They were given a storybook depicting multiple views of 2 children. They returned to the laboratory 2 weeks later and used a "magic wand" to play a computer game that tested their ability to recognize the familiarized faces and their own face based on the spacing of feature...

The leadership and advisory boards of American science agencies are largely organized according to the ideas set forth by an influential scientist, Dr. Vannevar Bush, after World War II. Although publicly funded, only experts control what research is funded how each agency operates. Wielding his unique position power war, Bush suppressed adversary, Senator Harley Kilgore, resulting in absence p...

Gardens are both a source of plant species that invade native vegetation (bush) and places can invade. We test the hypotheses richness adventive exotic trees in suburban gardens declines with distance from bush, type garden strongly influences establishment trees. The woody front houses on randomly selected streets three Hobart suburbs were observed street, along type. Distance bush boundary wa...

If multiple opportunities are available to review to-be-learned material, should a review occur soon after initial study and recur at progressively expanding intervals, or should the reviews occur at equal intervals? Landauer and Bjork (1978) argued for the superiority of expanding intervals, whereas more recent research has often failed to find any advantage. However, these prior studies have ...
