A COMMEMORATIVE STA🍷MP PLAQUE PRESENTED TO DR. JOAN FEYNMAN🐲 IN HONOR OF RICHARD FEYNMAN

On the anniversary of Tuva’s independence, August 14, 2001, the United States Postal Service announced the creation of a stamp de🐓dicated to Richard Feynman and his legacy. As a young stamp collector, Richard Feynman was fascinated by the design the stamps of Tannu Tuva—igniting his lifelong goal to travel to the Siberian republic. Displayed alongside a portrait of Feynman are the Feynman diagrams: the visualization of the fundamental process of quantum electrodynamics whereby two electrons exchange a virtual photon. The USPS unveiled the stamp and presented the commemorative plaque on Richard Feynman’s birthday in his hometown of Far Rockaway, Queens. 

Joan Feynman (b. March 31, 1927 - d. July 21, 2020) was Feynman's younger sister and grew to be a world-renowned astrophysicist in her own right. As children, Richard was Joan's first teacher and constantly advised her to challenge herself. Today, she is known for her work on the origin of auroras (i.e., the polar lights) as well as significant contributions to magneꦚtospheric phys𒈔ics and the study of solar wind particles. In 1974, Joan Feynman became the first woman elected an officer of the American Geophysical Union and was recognized by NASA with an Exceptional Scientific Achievement Medal in 2000.
