Step on a scale and you’ll get a quick measure of your weight. Weighing galaxy clusters, groups of hundreds or thousands of galaxies bound together by gravity, isn’t so easy. But scientists have many ways to do it.
Tucked in a small laboratory at the Department of Energy's SLAC National Accelerator Laboratory, a team of scientists from the Stanford Institute for Materials and Energy Sciences (SIMES) is making and testing new types of lithium-ion batteries. Their goal: create a battery five times better than the ones we use today.
Scientists have found a way to estimate uncertainties in computer calculations that are widely used to speed the search for new materials for industry, electronics, energy, drug design and a host of other applications.
