Timeline

1927

Joan Feynman (March 31, 1927 – July 21, 2020) was an American astrophysicist.

She made contributions to the study of solar wind particles and fields, sun-Earth relations, and magnetospheric physics.

In particular, Feynman was known for developing an understanding of the origin of auroras.

She was also known for creating a model that predicts the number of high-energy particles likely to hit a spacecraft over its lifetime, and for uncovering a method for predicting sunspot cycles.

Feynman was raised in the Far Rockaway section of Queens, New York City, along with her elder brother, Richard Feynman (who became a Nobel Prize-winning physicist).

Her parents were Lucille Feynman (née Phillips), a homemaker, and Melville Arthur Feynman, a businessman.

Her parents, both Ashkenazi Jews, originated from Minsk, Belarus (then in Russian Empire) and Poland.

Joan was an inquisitive child, and she exhibited an interest in understanding the natural world from an early age.

However, her mother and grandmother both dissuaded her from pursuing science, since they believed that women's brains were not physically capable of understanding complex scientific concepts in the way that men's brains could.

Despite this, her brother Richard always encouraged her to be curious about the universe.

It was he who originally introduced young Joan to auroras when, one night, he coaxed her out of bed to witness the northern lights flickering above an empty golf course near their home.

Later, Feynman found comfort in an astronomy book given to her by her brother.

She became convinced that she could, in fact, study science, when she came across a graph based on research by astronomer Cecilia Payne-Gaposchkin.

1948

In 1948 Feynman earned a bachelor's degree in physics from Oberlin College.

She later attended Syracuse University, where she studied solid state theory in the physics department under Melvin Lax.

During her graduate years, Feynman took a year off to live with her husband in Guatemala, where they studied the anthropology of the Maya peoples who lived there.

1957

She was a co-author, along with her husband and Betty J. Meggers, of a 1957 paper on anthropology.

1958

Feynman eventually earned her doctorate in physics in 1958.

Her thesis was on the "absorption of infrared radiation in crystals of diamond-type lattice structure".

She also completed postdoctoral work at Columbia University's Lamont Geological Observatory.

Joan Feynman spent the bulk of her career studying the interactions between the solar wind and the Earth's magnetosphere.

1971

While working at the NASA Ames Research Center in 1971, Feynman discovered that the periodic spouting of solar material known as a solar coronal mass ejection (CME) could be identified by the presence of helium in the solar wind.

This was an important find because, although CME's were known at the time, they had until then been difficult to detect.

After her time at NASA Ames, Feynman moved on to research posts with the High Altitude Observatory; the National Center for Atmospheric Research in Boulder, Colorado; the National Science Foundation in Washington, DC; and Boston College in Massachusetts.

1985

In 1985 Feynman accepted a position at the Jet Propulsion Laboratory in Pasadena, California, where she remained until her retirement.

Feynman made a critical discovery about the nature and cause of auroras.

Using data collected by NASA spacecraft Explorer 33, she demonstrated that the occurrence of auroras is a product of the interaction between the Earth's magnetosphere and the magnetic field of the solar wind.

Feynman helped to develop a model for estimating the environmental hazards of the local space environment.

High-velocity coronal mass ejections are known to cause geomagnetic storms, which can have dangerous effects on both spacecraft and on humans in space.

Fast-moving coronal mass ejections cause shock waves in the solar wind, speeding up solar particles and instigating geomagnetic storms as the particles arrive at the outer edge of Earth's magnetosphere.

Often, the commencement of such storms is coupled with a high influx of protons, which can wreak havoc on communications systems and space flight activities.

Feynman's model ultimately helped engineers determine the flux of high-energy particles that would affect a spacecraft over its functional lifetime.

Her work in this area led to important new developments in spacecraft design.

Later in her career, Feynman studied climate change.

She was particularly interested in transient solar events and solar cycle variations.

She studied the influence of the sun on patterns of wintertime climate anomalies known as the Arctic oscillation or North Annular Mode (NAM).

Together with her colleague and husband Alexander Ruzmaikin, she found that during periods of lower solar activity, the NAM index is systematically lower.

Such periods of low solar activity coincide with cooling periods for certain parts of the world, for example, in Europe during the Little Ice Age.

Feynman and her colleagues also discovered a link between solar variability and climate change in ancient water levels of the Nile River.

During periods of high solar activity, conditions around the Nile were found to be drier, and when solar activity was low, conditions were wetter.
