Astronomer Johannes Kepler: birth town Weil der Stadt

I first heard the name “Kepler” way back in high school. I had no idea “Kepler” would embody a winding trail of education, knowledge, a “first life” (career), and a deep lifelong appreciation of science. Thankfully, what’s transformed has been a “second life” opened to another world with more questions, some of which have led to unexpected places. Perhaps, the cost is a solitary quest for answers, but ultimately, my motivation has always been clear: it’s because I need to know.

In the same way Kepler, like many others before and after, looked up into the night sky and asked a simple question: “why do stars and planets appear and move as they do in the night sky?”

To the here and now, my questions begin and land on our own planet.

For example, where was Kepler born? Where is this place? Are there any traces in those spaces?

First, who was Kepler?

My Salzburg: Christian Doppler’s birth house

In crossing the pedestrian bridge over the Salzach river, every step takes me away from the famous view of the fortress over Old Town classics of steeples and baroque in Salzburg. Before I get to where I want to be, I have to cross a busy street in the afternoon rush which has come to a halt. Wailing sirens approach and recede as red and white “Rettungswagen” race to the emergency situation somewhere in the city. The cyclical lights are in my favour, and upon turning the corner, I see the sign that tells me I’ve arrived.

One self-assigned goal during three weeks of travel within Austria was the search for places associated with physicists and mathematicians of my youth. And by youth, I mean the tender twenties when all I cared about was a succinct explanation of the natural world through various equations1. In Alpbach, I found Erwin and Annemarie Schrödinger’s grave. In Vienna, I found Ludwig Boltzmann’s grave. Here in Salzburg across the street from the Mozart family house, I found Christian Doppler after whom the Doppler effect is named.
