Modern science reveals that matter is made of atoms and molecules. Molecules in liquids and gases move randomly; there is an average distance between two nearest molecules. This distance is used to model the properties of the gas. However, there are certain problems, like turbulence, that cannot be solved using just the distance, which is a single scale. We need to consider all scales from large to small. Such systems are called multiscale systems.
New research reveals that a unique Indian skink species arrived on the subcontinent by rafting across the ocean from Southeast Asia millions of years ago, a journey made possible by fluctuating sea levels.
