New Digit Flipping Study Guide
Flip your digits! We’ve added a new Digit Flipping Study Guide that shows how to solve digit flipping challenges with two-digit numbers. These types of problems are challenging at first, but with practice you can become a pro. It can deepen your understanding of place value and working with systems of equations.
Alexander Von Humboldt
Scientist Explorer The German naturalist Friedrich Heinrich Alexander von Humboldt’s (1769-1859), known in English as Alexander von Humboldt, is considered the father of modern geography and ecology. He was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. Humboldt’s quantitative work on botanical geography laid the foundation for the field of biogeography. His advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring.
A Mathematician’s Lament
A musician wakes from a terrible nightmare. In his dream he finds himself in a society where music education has been made mandatory. “We are helping our students become more competitive in an increasingly sound-filled world.” Educators, school systems, and the state are put in charge of this vital project. Studies are commissioned, committees are formed, and decisions are made–all without the advice or participation of a single working musician or composer.
