Fotoeins Friday at Uni Vienna: Joseph & Karl Littrow

Throughout the month, I’m highlighting notable physicists who’ve been memorialized within the Arcade Courtyard in the main building of the University of Vienna:

2 Apr: Lise Meitner;
9 Apr: Christian Doppler, Erwin Schrödinger;
16 Apr: Joseph Littrow, Karl Littrow;
23 Apr: Josef Stefan;
30 Apr: Ludwig Boltzmann.

These are all names whose work and discovery form the historical and scientific basis of my university education in the field of physics.


A wall plaque memorializes astronomers Joseph Littrow and (his son) Karl Littrow at left and right, respectively. Joseph was director of the Vienna Observatory from 1819 to 1842; Karl succeeded his father as director from 1842 to 1877.

The Littrow crater on the Moon is named after Joseph, but he’s also best known in physics for his optics inventions: the Littrow prism and the Littrow configuration optimizing the performance of a spectrograph with a specially designed diffraction grating.

The university’s historical main building is inside the city’s Old Town which has been inscribed as UNESCO World Heritage Site since 2001. I made the photo above on 16 May 2018 with a Fujifilm X70 fixed-lens prime and the following settings: 1/30-sec, f/2.8, ISO1000, and 18.5mm focal length (28mm full-frame equivalent).

Fotoeins Friday at Uni Vienna: Doppler & Schrödinger

This month I’m highlighting notable physicists who’ve been memorialized within the Arcade Courtyard in the main building of the University of Vienna:

2 Apr: Lise Meitner;
9 Apr: Christian Doppler, Erwin Schrödinger;
16 Apr: Joseph Littrow, Karl Littrow;
23 Apr: Josef Stefan;
30 Apr: Ludwig Boltzmann.

These are names whose work and discovery form part of the historical and scientific basis of my university education in the field of physics.


Shown in the image are memorials to Christian Doppler and Erwin Schrödinger at left and right, respectively. My translation to the inscription on the Doppler memorial inscription reads:

Christian Doppler, 1803-1853:
Professor of physics at Vienna University, 1850-1853.
The Doppler principle has ensured the Doppler name for all time.

With his birth house in Salzburg as backdrop, I briefly describe the physics of the Doppler effect.

The Schrödinger memorial highlights an early 20th-century revolution in science in the form of quantum mechanics: the physics of the atom and its constituents. The well-known equation representing Newton’s 2nd Law, “F = ma”, is to classical mechanics, as the following equation is to quantum mechanics.

The equation on his memorial, and on the gravestone.

This generalized form of the time-dependent Schrödinger equation describes a physical system, represented by ψ, changing with time. I was able to “localize” the final resting place for him and his wife in the alpine Austrian town of Alpbach.

Fotoeins Friday at Uni Vienna: Lise Meitner

Throughout the month, I’m highlighting notable physicists who’ve been memorialized within the Arcade Courtyard in the main building of the University of Vienna:

2 Apr: Lise Meitner;
9 Apr: Christian Doppler, Erwin Schrödinger;
16 Apr: Joseph Littrow, Karl Littrow;
23 Apr: Josef Stefan;
30 Apr: Ludwig Boltzmann.

These are all names whose work and discovery form the historical and scientific basis of my university education in the field of physics.


Lise Meitner (1878-1968) was an Austrian physicist whose work with chemist Otto Hahn produced breakthroughs in our understanding of atomic and nuclear physics. Meitner overcame obstacles blocking women from studying and working at universities in the early 20th-century. She wanted to study at the University of Vienna, and thanks to her parents’ support, she studied on her own and successfully passed the university’s entrance examination in 1901. She studied physics over the next five years; physicist Ludwig Boltzmann was one of her instructors and advisors. In 1906, Meitner became the 3rd woman at the university to receive a doctorate in physics (after Olga Ehrenhaft-Steindler and Selma Freund). In 1907, she moved to Berlin where she would stay for over 30 years. In 1926, she became one of the first women appointed to associate professor at Berlin University and the first woman as professor of physics in Germany. Her Jewish lineage meant loss of title and employment, and in mid-1938, a hasty departure from Germany and exile to Sweden. In 1939, she and her nephew physicist Otto Frisch published a short breakthrough paper with their theoretical analysis of the newly discovered process of “nuclear fission” in experiments with uranium and thorium by Otto Hahn and Fritz Strassmann. Later, she refused to help with the construction of an atomic bomb and objected to the use of nuclear weapons for the rest of her life.

Like many, I believe Lise Meitner should have been honoured as co-Laureate for the 1944 Nobel Prize in Chemistry awarded solely to Otto Hahn. In mid-2016, the University of Vienna unveiled a monument in her honour.

The university’s historical main building is inside the city’s Old Town which has been inscribed as UNESCO World Heritage Site since 2001. I made the photo above on 16 May 2018 with a Fujifilm X70 fixed-lens prime and the following settings: 1/60-sec, f/9, ISO1000, and 18.5mm focal length (28mm full-frame equivalent).

My Vienna: Triple Schimkowitz

Above/featured: Musenhaus (Muse House), Linke Wienzeile in Vienna – 18 May 2018.

Early 20th-century European artist Othmar Schimkowitz was one of many key figures in Vienna Modernism, an art movement which celebrated its centennial in 2018 in the Austrian capital city. Schimkowitz was born in Hungary and became well-known in Vienna for his architectural sculptures. In 1898, he joined the (Vienna) Secession, a group of artists which included Josef Hoffmann, Gustav Klimt, Max Kurzweil, Carl Moll, Koloman Moser, and Joseph Maria Olbrich.

Sculptures by Schimkowitz are often seen in a variety of architectural creations by Otto Wagner. Here below are three Schimkowitz examples in Vienna; all are accessible with public transport from Wiener Linien (WL).

My Tirol: Stubai alpine valley


(Spring 2018.)

After the morning to and from Scharnitz, I returned to Innsbruck, and immediately headed south into the Stubai valley for the afternoon and early-evening. I had enough time to make a short walk in each of the towns Neustift and Fulpmes, but truth told, I would’ve preferred a minimum of one full day to appreciate more fully the spring-summer rhythms in the river valley and ascend the cable cars up both Kreuzjoch and Elfer, plus another day to the very end of the Stubai valley to Mutterbergalm, and up Schaufelspitze for views of the Stubaier Gletscher (Stubai Glacier) at “the top of Tirol.”

The present description is a part of my 1-day trips within Tirol, including:

•   Alpbach valley.
•   Brenner Pass.
•   Scharnitz & Porta Claudia.
•   Wilder Kaiser.
