Hanna Reisler

Hanna Reisler 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 Hanna Reisler rather than just read about it. In short: Hanna Reisler (née Bregman, Hebrew: חנה רייסלר) is an Israeli-American Professor of Chemistry at the University of Southern California. She is interested in the reaction dynamics of molecules and free radicals, as well as the photodissociation in the gas phase.

Key takeaways

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

Reference excerpt

Hanna Reisler (née Bregman, Hebrew: חנה רייסלר) is an Israeli-American Professor of Chemistry at the University of Southern California. She is interested in the reaction dynamics of molecules and free radicals, as well as the photodissociation in the gas phase. Reisler established the University of Southern California Women In Science and Engineering (WISE) program.

Early life and education Reisler grew up in Israel. She studied at the Hebrew University of Jerusalem, earning her undergraduate degree in 1964. She moved to the Weizmann Institute of Science for her graduate studies, completing her PhD in physical chemistry in 1972. Reisler worked as a postdoctoral fellow with John Doering at Johns Hopkins University. Here she studied the inelastic scattering of ions.

Postdoctoral Research and Early Career After completing her PhD, Reisler moved to the United States to conduct postdoctoral research at Johns Hopkins University. There, she worked in the laboratory of physicist John Doering.[7][8] Her research at Johns Hopkins centered on the inelastic scattering of ions, contributing to a deeper understanding of energy transfer processes in molecular collisions.[9][10] This early work laid the groundwork for her later studies in molecular beam techniques and the dynamics of transient molecular species.Research and career Reisler was a researcher at the Soreq Nuclear Research Center. In 1977, she joined the University of Southern California as a research associate with Curt Wittig, before being appointed Associate Professor in 1987. She was a member of the Center for the Study of Fast Transient Processes, which was supported by the United States Army Research Laboratory. Reisler and Wittig worked on gas-surface and solid-state interactions. The first paper she published while at USC was included in James T. Yardley's book on energy transfer. During her tenure at USC, Reisler has worked in the Department of Electrical Engineering, Physics, and Chemistry. She was made a full Professor at the University of Southern California in 1991. In his biography, Wittig described Reisler as "one of the most important faculty members of the College of Letters, Arts, and Sciences, if not the entire University". She is interested in the molecular mechanisms of chemical reactions. Reisler has looked at molecular transport and guest-host interactions in thin films. Her group at USC has evaluated vibrational pre-dissociation dynamics of hydrogen-bonded dimers and large clusters. She also works on the reactions of diradicals and amorphous solid water. In particular, she has studied chloromethyl radicals, hydroxyl radicals, and NO dimers.

Academic service and advocacy In 2000, there were only three women members of the faculty across the USC Viterbi School of Engineering. Reisler founded the Women In Science and Engineering (WISE) program at the University of Southern California. The program was launched with an anonymous $20 million donation, and continues to receive a $1 million per year endowment. She advocated for more comprehensive support for scientists with families. It has since provided fellowships and childcare support for students and postdocs. She created a networking group that meets once a month to share information and resources. She was appointed the Lloyd Armstrong Jr. Chair in Science and Engineering, which looks to advance the careers of women scientists. She is involved with the mentorship of early-career scientists. Her commitment to mentoring has been recognized by the University of Southern California, which launched a mentorship award in her honour. She was honoured by Johns Hopkins University and nominated to their Society of Scholars in 2018.

Worked examples

Example 1 — a first encounter with Hanna Reisler

Start with the simplest possible case. Write down what Hanna Reisler 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 Hanna Reisler 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 Hanna Reisler 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 Hanna Reisler

In research
Hanna Reisler 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 Hanna Reisler 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
Hanna Reisler is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fellows of the American Physical Society, Hebrew University of Jerusalem alumni, Israeli women academics, so understanding it makes those chapters shorter.
In everyday life
Look for Hanna Reisler 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.
