Johanna Stachel is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Johanna Stachel rather than just read about it. In short: Johanna Barbara Stachel (born 3 December 1954 in Munich) is a German nuclear physicist. She is a professor in experimental physics at the University of Heidelberg (Ruprecht-Karls-Universität Heidelberg).

Key takeaways

Johanna Stachel belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Johanna Stachel to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Johanna Stachel from memory before moving on to harder problems.

Reference excerpt

Johanna Barbara Stachel (born 3 December 1954 in Munich) is a German nuclear physicist. She is a professor in experimental physics at the University of Heidelberg (Ruprecht-Karls-Universität Heidelberg). Stachel is a former president of the German Physical Society (DPG).

Early life and education Johanna Stachel completed secondary education in 1972 at the Spohn Gymnasium in Ravensburg. She studied physics and chemistry at Johannes Gutenberg University Mainz and the Swiss Federal Institute of Technology (ETH Zürich) and received a degree from the Johannes Gutenberg University Mainz in 1978. In 1982 she obtained a doctorate in physics from the same university.

Career From 1983 to 1996, Stachel studied and worked at the State University of New York (SUNY) at Stony Brook and Brookhaven National Laboratory where she met her future husband professor Peter Braun-Munzinger. In 1996 she was named professor at the University of Heidelberg. Stachel was spokesperson of the CERN SPS experiment CERES/NA45 and directed the developed the ALICE Transition Radiation Detector. Stachel was elected President of the German Physical Society for a two-year term starting in 2012. Her two primary priorities as president were first to defend basic research by showing its importance and promote physics education in schools by improving the training of physics teachers and the standards across German schools. During her career, she has delivered over 150 lectures at international workshops and conferences and has participated in over 100 seminars and colloquia.

Research interests Stachel's research focuses on understanding relativistic heavy-ion collisions and quark-gluon plasma. She is member of the LHC ALICE Collaboration at CERN in Geneva. Stachel is also interested in developing detectors that are needed to carry out these experiments in particle physics.

Offices and honorary offices Among her academic responsibilities are:

From 2003 to 2005 she was dean of the faculty of Physics and Astronomy of the University of Heidelberg. Until 2012, she continued to serve as vice-dean. Associate editor for the journal Nuclear Physics A. Membership of the Advisory Board of the Wilhelm and Else Heraeus Foundation. Membership of the University Council of the Vienna University of Technology starting in 2018 for a 5-year term. International councilor with the American Physical Society from 2016–2019. On 28 March 2014 she received the honorary membership of the Physikalischen Verein, Frankfurt, where she is listed along with Heinrich Hertz, Albert Einstein and Otto Stern.

Honors and awards 1986: Sloan Research Fellowship 1988: Presidential Young Investigator Award 1996: Fellow of the American Physical Society 1998: Member of the Berlin-Brandenburg Academy of Sciences and Humanities 1999: Order of Merit of the Federal Republic of Germany 2001: Lautenschläger Research Prize 2012: Member of the Academia Europaea 2014: Lise Meitner Prize 2014: Full member of the Heidelberg Academy of Sciences and Humanities 2015: Member of the Academy of Sciences Leopoldina 2017/18: Lise Meitner Lecture in Vienna 2019: Stern-Gerlach-Medal 2021: Officers Cross of the Order of Merit of the Federal Republic of Germany

Worked examples

Example 1 — a first encounter with Johanna Stachel

Start with the simplest possible case. Write down what Johanna Stachel claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Johanna Stachel before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Johanna Stachel ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Johanna Stachel

In research: Johanna Stachel appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Johanna Stachel in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Johanna Stachel is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1954 births, 20th-century German physicists, 20th-century German women physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Johanna Stachel outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
