Randomness: What is it? Why do we need it? How do we create it?

August 4, 2022

What is it? Randomness is maybe something people do not think so much about. But: TRUE RANDOMNESS IS VERY IMPORTANT! This post is only a “gentle introduction” to this whole randomness-field. Originally it’s a big rabbit-hole filled with interesting science.…

Theoretical Tutorials

Earlier we have written blog posts about both Ohm’s Law and Kirchhoff’s Laws. It’s time to put these in action combined to analyze simple DC circuits. Sounds fun, right!? Don’t worry, it’s pretty easy and straight forward, and we’ll walk…
