Letters to Bernd

A few months ago, I found an old notebook of mine with notes on topics Bernd P. Luedecke taught me. Back then, I already had the idea to blog about those topics as letters to him, my former teacher. I will formalize and digitalize these letters one by another on this page. But first, a small introduction to Bernd P. Luedecke.

Bernd P. Luedecke
He was my professor for half a year and he taught me a lot. Also a lot of bogus stuff. I rank him amongst the best teachers I ever had with long term impact. He is a cynical old man with deep mathmatical understanding, heaps of nsfw stories and insomnia.
 * Macquary University

Euler's identity
From all the things Bernd has, he also has an eye for beauty. In class, he again wandered off class-content material and told us one of his stories:
 * While he himself was a student his professor wrote the Euler identity     on the chalk board. He was the only one in the class who was struck so hard by its beauty that he started crying. His professor then turned to him and said with a deep, touched voice: "I see, Bernd, you understand."

As most of his stories, I suspect he was stretching the truth a little bit, but he brings across a very important point: Some relationships are beautiful and this mathematical one is mind-blowing.

I caught myself dreaming off while looking at that formula "what does it all mean?" Then, I came across Tau-Manifesto which declares Pi to be wrong and Tau to be equal to 2Pi: Put that one into the Euler formula and you start crying again, Bernd.

Now, what is the relationship between economics and economy? I fear, it is worse than the one between meterology and wheater. Empirically, weather would exists even without science of meteorology. I assume, one could also say, that economy would exist even without the study of economist. I am persuaded, that there is a empirical truth to be found in the very long past of human-existence. For now, let's just assume there is a th...
