My Vienna: Ludwig Boltzmann was here

The name is a large presence, particularly to many in science.

To others, the name might have little significance as any other name, like Helmut Grossuhrmacher. OK, I made that name up.

A name I didn’t make up is Ludwig Boltzmann, whose contributions to science are fundamental in an understanding of heat- or thermal-physics, thermodynamics, and statistical mechanics. After several years of undergraduate- and graduate-level physics, Boltzmann is one of many names imprinted into memory, firmly established in the left-side of my brain.

Boltzmann highlights

• b/✵ 20 February 1844 – d/✟ 5 September 1906.
• Born and raised in Vienna, Boltzmann enroled at age 19 in the University of Vienna to study mathematics and physics.
• Supervised by Josef Stefan, Boltzmann completed his doctoral dissertation “Über die mechanische Bedeutung des zweiten Hauptsatzes der mechanischen Wärmetheorie” (On the mechanical significance of the 2nd Law of Thermodynamics) in 1866 at the age of 22.
• 1869–1873: University of Graz, with visits to Heidelberg and Berlin.
• 1873–1876: University of Vienna.
• 1876–1890: University of Graz.
• 1890–1894: (Ludwig Maximilian) University of Munich.
• 1894–1900: after Josef Stefan’s retirement, Boltzmann returns as professor of mathematics and physics at University of Vienna.
• 1900–1902: Leipzig University.
• 1902–1906: University of Vienna; he also teaches physics, mathematics, and philosophy.
• Doctoral students Boltzmann supervised and advised included: Paul Ehrenfest, Lise Meitner, Stefan Meyer, Walther Nernst.
• Speaking tour of the United States in 1905, including his stay that summer in Berkeley at the University of California. Evident from his trip report, Reise eines deutschen Professors ins Eldorado, is his sense of humour.

Time has been kind to Vienna, a city filled with notable personalities in arts, architecture, music, and science. Throughout its cemeteries, the city has assigned “graves of honour” (Ehrengrab) for many, including Boltzmann. Finding his final spot was one of many favourite moments in 2018. However, Boltzmann’s significance to the University of Vienna, to the physics world, and to time I spent in physics persuaded me to create a short (walking-)tour of Vienna to highlight some of his traces and memorialization in the city.

Würzburg: Röntgen, X-rays, & 1st Nobel Prize in Physics

On my list and map, I placed the museum’s location as a “possible” to visit in the city. If I had time, I’d swing by and have a look, appealing to my fondness for science and the history of science.

Many arrive in Würzburg to visit the Residenz UNESCO world heritage site. On a daytrip from Frankfurt am Main, I duly visited the Residenz, and easily completed my initial visit requirements, as I knew I would. That’s when my inner voice (a.k.a., the spirit of B.Sc. ’90) reminded me insistently the museum was “simply and conveniently” on the return walk to the city’s central train station to fully complete my visit requirements.

I walked north from the Residenz, and followed the signs into the building for the Röntgen-Gedächtnisstätte (Röntgen Memorial) where X-rays were discovered. Standing inside the former laboratory space, I’m surrounded by artifacts, books, papers, tubes, equipment, and photographs.

I also feel a part of my undergraduate physics education has come full circle.

My Vienna: Ludwig Boltzmann in spring

I’m neither tragic nor hip, but I know a little bit about Canadian icon and band, The Tragically Hip, and specifically, a song of theirs called “Springtime in Vienna.”

I can’t play a musical instrument, but I especially liked listening to a performance of Johann Strauss II’s “An der schönen blauen Donau” (The Blue Danube) on an intercity river catamaran between Vienna and Bratislava.

What I’m totally convinced is when spring comes calling, I’m allergic to nature. I’m a living example to irritation and inflammation, and living consequence to nature’s response to spring.

Alpbach, Austria: finding Erwin Schrödinger

Localizing his final wavefunction in Alpbach.

It took a little effort: a train out from Innsbruck to Brixlegg, followed by a regional bus into another valley of countless valleys, accompanied by the illumination of sharp morning light, in a blanket of meadows and buttercups, under a deep ocean of impossibly blue skies. And on both sides of this river valley are an endless series of mountains, these peaks the smaller cousins to larger Austrian Alps nearby.

In Alpbach, the weekday morning is quiet, as the town begins to stir with people starting their work day. The bank has just opened, fresh baked bread and pastry and roasted coffee emanate from the cafe from around the corner, a couple of trucks rumble into town with deliveries. An older couple walks by, and there are mutual sunny greets of “Grüss Gott”. The church steeple glows yellow at this hour, and it’s easy to imagine with its bell the church is an aural and visual beacon for miles.

I’m drawn to the church because that was always the plan, to look for someone who’s buried in the church cemetery. Ordered rows of headstones lie as you would expect, but by the northwest gate, I find a single plaque on the bordering stone wall. The plaque reads: “Erwin Schrödinger, Nobelpreis für Physik, 1933”, and next to the plaque is Erwin and Annemarie Schrödinger’s final resting spot^%. Another academic pilgrimage completed.

Göttingen: a circle of Nobel Prize winning scientists

What: Circular feature celebrating Nobel Prize winners, all of whom worked at the city’s university.
Where: Stadtfriedhof (city cemetery) in Göttingen.

Göttingen is a university town in central Germany. Not only will I find a memorial to Nobel Prizes, I’m here also to acknowledge my academic training. I spent many years studying physics and astronomy, and while I’m no longer active in science research, I enjoy the search and discovery of the final resting spots for scientists whose work formed a significant part of my education. Visiting their graves provides direct historical connection to “academic predecessors”; to go beyond the abstraction of simply learning their names and contributions to science, the gravestones belong to real people with keen minds, family lives, and all too human imperfections.

45 Nobel Prize laureates have been or are connected with the Georg-August-Universität Göttingen as of posting (2018). That’s a phenomenal number, as this single institution accounts for 8 per cent of all Nobel Prizes (585 as of 2017).
