Reference excerpt

Margaret Mary Murnane (born 23 January 1959) is an Irish physicist, who served as a distinguished professor of physics at the University of Colorado Boulder, having moved there in 1999, with past positions at the University of Michigan and Washington State University. She is the director of the STROBE NSF Science and Technology Center and a researcher in laser science and technology. Her interests and research contributions span topics including atomic, molecular, and optical physics, nanoscience, laser technology, materials and chemical dynamics, plasma physics, and imaging science. Her work has earned her awards including the MacArthur Fellowship award in 2000, the Frederic Ives Medal/Quinn Prize in 2017, the highest award of The Optical Society, and the 2021 Benjamin Franklin Medal in Physics.

Early life Born and raised in County Limerick, Ireland, Murnane became interested in physics through her father who was a primary school teacher. She received her B.A. and M.S. from University College, Cork. She moved to the United States to study at the University of California, Berkeley, where she earned her PhD in 1989 under Roger Falcone. She is married to Henry Kapteyn. They work together and operate their own lab at JILA at the University of Colorado.

Career Murnane has co-authored more than 500 articles in peer reviewed journals, with her work receiving around 35000 citations. She is a founder of the field of ultrafast X-ray science, having made contributions to this area of research in every decade since the 1980s. She has developed her university-based laboratory effort in collaboration with Kapteyn. In their lab, Murnane, Kapteyn, and their students make lasers whose beams flash like a strobe light – except that each flash is a trillion times faster. These lasers, like camera flashes, make it possible to record the motions of atoms in chemical reactions, and of atoms and electrons in materials systems. Some of her lasers can generate pulses of less than 10 femtoseconds.The very high peak power of these ultrashort laser pulses makes it possible to coherently upconvert light to much shorter wavelengths, in the extreme ultraviolet and soft X-ray region of the spectrum. This high harmonic generation process makes possible a tabletop-scale X-ray laser light source. Murnane explored the use of femtosecond lasers for x-ray generation and has made substantive contributions to many aspects of this area of research, including the understanding of the high harmonic process, the laser technology required to use this process to implement practical tabletop light sources for applications, and in applying this new source to make fundamental discoveries in areas ranging from basic atomic and chemical dynamics to materials dynamics, to nanoimaging. She is also a founder of the area now known as experimental "Attosecond Science", having performed experiments that demonstrated the ability to manipulate electron dynamics with attosecond precision.

She is the co-founder of the laser company KMLabs, Inc., for which Intel Capital is a co-investor.

Worked examples

Example 1 — a first encounter with Margaret Murnane

Start with the simplest possible case. Write down what Margaret Murnane 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 Margaret Murnane 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 Margaret Murnane 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 Margaret Murnane

In research: Margaret Murnane 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 Margaret Murnane 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: Margaret Murnane is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1959 births, 20th-century Irish physicists, 20th-century women physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Margaret Murnane 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.
