In this article, the Hamming code is first built with seven coins and without a computer and tested practically. You will learn how test bits can detect errors in a transferred bit sequence and determine the faulty position. The procedure is then programmed in a Jupyter notebook with Python.

Binomial coefficient as a marble run – Mathematics to touch
Welcome to "Binomial coefficient as a marble run – Mathematics to touch”! In this article we present an innovative marble run based on the modular system Marble Castle. This special marble run works similarly to a Galtonboard, but the marbles do not fall by chance, but always alternately to the left and right. This results in an exact binomial distribution that vividly illustrates the concept of Pascal's triangle. Immerse yourself in the world of mathematics and discover how playful learning works!
