Soil erosion is a widespread problem in rural and urban Queensland. If we want to save our soils, we need to understand the different types of erosion that can occur. Queenslandâs high intensity summer rainfalls represent a significant risk of erosion by water.
Lagrangian function. Lagrangian function, also called Lagrangian, quantity that characterizes the state of a physical system. In mechanics, the Lagrangian function is just the kinetic energy (energy of motion) minus the potential energy (energy of position).
This spot is called the Earth-Sun L2 point, the second of five Lagrangian Points named for Joseph-Louis Lagrange (1736-1813) who calculated their existence. In practice, a spaceship is actually more stable orbiting around the L2 point than trying to remain at the precise point.
