Submitted by TheFrankensTeam:In the model you can change the number of dots and the deviation too. If you set the “type demo” to dynamic it will make possible to analyse how the wave-pattern changes when deviation grows.

## BeagleBone Tutorial: Accessing Main Memory From the PRU (and visa versa)

This tutorial shows how to access any part of the main memory from within the PRU, and reasons you shouldn’t.

Is this all? There’s so much more to Friedman numbers. Consecutive ones… They exist in different bases… They work with Roman numerals, which is fucking cool.

The brachistochroneThis animation is about one of the most significant problems in the history of mathematics: t

he brachistochrone challenge.

If a ball is to roll down a ramp which connects two points, what must be the shape of the ramp’s curve be, such that the descent time is a minimum?Intuition says that it should be a straight line. That would minimize the distance, but the minimum

timehappens when the ramp curve is the one shown: acycloid.Johann Bernoulli posed the problem to the mathematicians of Europe in 1696, and ultimately, several found the solution. However, a new branch of mathematics, calculus of variations, had to be invented to deal with such problems. Today, calculus of variations is vital in quantum mechanics and other fields.
