A generalization of the two-dimensional spectral forecast equations is suggested, whereby the atmospheric flow field in horizontal and vertical directions is represented in terms of orthogonal functions, which are eigenfunctions of certain differential operators in the three-dimensional equations. The technique is applied to the quasi-geostrophic potential vorticity equation.

In one of the most exciting and accessible explanations of The Theory of Relativity in recent years, Professors Brian Cox and Jeff Forshaw go on a journey to the frontier of 21st century science to consider the real meaning behind the iconic sequence of symbols that make up Einstein's most famous equation, exploring the principles of physics through everyday life.

Ready, Set, Hop! (Building Equations): Who's the better hopper? Matty, the tall frog? Or Moe, who's just plain big? Only a hopping contest can settle the matter. It takes Moe only five hops to make it to the big rock. Matty needs two more hops. So how many hops did Matty take? (5 hops + 2 hops = ?). The happy hoppers keep going untils̮plash!t̮hey're in the pond. Knowing how equations are built is central to children's learning how to interpret and...

Algebra II is the fork in the road. Those who succeed in this second part of the algebra sequence are well on their way to calculus and higher mathematics, which open the door to careers in science, engineering, medicine, economics, information technology, and many other fields. Algebra II starts by reviewing functions, graphing, and polynomials from Algebra I, and then introduces new topics, such as conic sections, roots and radicals, exponential...
