The old axiom is that 90% of a tree’s roots are in the top foot of soil. To some degree, they mirror the limb growth. Branches of most trees are relatively horizontal, live oaks being a classic ...

In number theory, the Stern–Brocot tree is an infinite complete binary tree in which the vertices correspond one-for-one to the positive rational numbers, whose values are ordered from the left to the right as in a binary search tree. The Stern–Brocot tree was introduced independently by Moritz Stern and Achille Brocot .
Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
