Chien-Shiung Wu was a Chinese-American physicist who made significant contributions to the field of nuclear physics. Born in China in 1912, Wu received her undergraduate and graduate education in China before moving to the United States in 1936 to pursue her PhD at the University of California, Berkeley.

After completing her PhD, Wu began her career as a research physicist at the University of California, Berkeley and later at Columbia University. It was during her time at Columbia that Wu conducted the experiments that would come to define her career.

Wu’s most notable achievement was her work on the experiment known as the Wu experiment. The experiment disproved the law of conservation of parity, a fundamental principle in physics that stated that certain physical processes should be mirror symmetric. Wu’s experiment showed that this symmetry did not hold true in certain types of radioactive decay, leading to a revolution in our understanding of the subatomic world.

Wu’s groundbreaking work earned her the nickname “First Lady of Physics” and led to the Nobel Prize in Physics being awarded to her colleagues Tsung-Dao Lee and Chen-Ning Yang in 1957, but Wu was not included in the prize. Wu’s exclusion from the Nobel Prize sparked controversy and led to a reevaluation of the way the Nobel Committee recognizes the contributions of women and minorities in science.

Despite the lack of recognition from the Nobel Committee, Wu’s contributions to physics were widely acknowledged and she received numerous awards and honors for her work, including the National Medal of Science in 1975. Wu passed away in 1997, but her legacy lives on as a trailblazer for women in science and an inspiration for future generations of physicists.

2. Hedy Lamarr

Hedy Lamarr, born Hedwig Eva Maria Kiesler, was not only a successful Hollywood actress, but also an inventor and a pioneer in the field of wireless communication. Lamarr, along with composer George Antheil, developed a frequency-hopping system during World War II, which was intended to make radio-controlled torpedoes more difficult for enemies to detect and jam. This technology, known as spread spectrum, is now used in wireless communication such as Wi-Fi and Bluetooth.

Lamarr’s invention was ahead of its time and was not implemented during World War II, but the principles of her design were later incorporated into modern wireless technology. In 2014, she was posthumously inducted into the National Inventors Hall of Fame for her contributions to the field of wireless communication.

It is quite remarkable that she was able to make such a significant contribution in the field of technology despite facing gender discrimination and lack of opportunities for women at that time. Her work serves as an inspiration for young women and girls to pursue their passion and to not let societal barriers limit their potential.

3. Rosalind Franklin

Rosalind Franklin Rsp 1

Despite her crucial role in the discovery of the structure of DNA, Rosalind Franklin’s contributions were not widely recognized during her lifetime. Born in London in 1920, Franklin studied physical chemistry at Cambridge University before moving to Paris to work on X-ray crystallography. It was there that she developed her expertise in the field and began working on DNA fibers.

In 1951, Franklin joined King’s College London, where she continued her work on X-ray diffraction images of DNA. It was during this time that she captured the now-famous “Photo 51,” which provided key information about the structure of DNA. However, the photograph was shown to James Watson and Francis Crick without Franklin’s knowledge or consent, and they used the information to determine the double helix structure of DNA.

Despite her crucial role in the discovery, Franklin was not included in the 1962 Nobel Prize in Physiology or Medicine that was awarded to Watson, Crick, and Maurice Wilkins. It was not until years later that Franklin’s contributions were fully acknowledged and appreciated.

Franklin’s legacy lives on today, as her pioneering work in X-ray crystallography and her discovery of the structure of DNA continue to shape the field of molecular biology. Her story serves as a reminder of the often-overlooked contributions of women in STEM fields and the importance of giving credit where credit is due.

Rachel Carson was a marine biologist and conservationist who dedicated her career to studying the natural world and raising awareness about the dangers of pesticides and other chemicals on the environment. Her book “Silent Spring” was a seminal work that exposed the harmful effects of pesticides on birds, animals, and humans, and sparked a national debate about the use of these chemicals.

Carson’s book was based on years of research and personal observation, and it detailed the devastating effects of pesticides such as DDT on the environment. She documented how DDT and other pesticides were not only killing off beneficial insects and birds but also contaminating the soil and water, and causing health problems in animals and humans. The book also exposed how the chemical industry and government agencies were downplaying or ignoring the dangers of these chemicals.

The publication of “Silent Spring” led to a nationwide movement to ban DDT and other harmful pesticides and to establish government regulations to protect the environment. As a result of Carson’s work, the U.S. government banned DDT in 1972, and the Environmental Protection Agency (EPA) was established in 1970.

Carson’s book and her tireless efforts to raise awareness about the dangers of pesticides were instrumental in shaping modern environmentalism and catalyzing the environmental movement. Her work continues to influence environmental policy and conservation efforts to this day.

6. Lise Meitner

Lise Meitner Rsp

Lise Meitner was a pioneering physicist whose work in the field of nuclear physics helped to revolutionize our understanding of atomic nuclei and radioactivity. Born in Vienna in 1878, Meitner studied physics at the University of Vienna, where she was the only woman among the students in her class. Despite facing discrimination and barriers due to her gender, Meitner went on to earn her doctorate in physics in 1906.

Meitner began her career as a research physicist at the Kaiser Wilhelm Institute for Chemistry in Berlin, where she worked with Otto Hahn. Together, they conducted experiments on the properties of radioactive elements, and it was their work that led to the discovery of nuclear fission, a process in which the nucleus of an atom is split into smaller nuclei, releasing a large amount of energy.

Meitner’s contributions to this discovery were significant, yet she did not receive the recognition that many felt she deserved. In 1944, Hahn was awarded the Nobel Prize in Chemistry for his role in the discovery, but Meitner was not included. Some have attributed this oversight to Meitner’s Jewish heritage and the fact that she had been forced to flee Germany in 1938 due to the rise of the Nazis.

Despite this injustice, Meitner’s work has had a lasting impact on the field of nuclear physics. Her discovery of nuclear fission was crucial in the development of nuclear energy and the atomic bomb. Meitner continued to work in the field of nuclear physics throughout her career, including her work as a professor at the University of Stockholm, where she became the first woman in Sweden to hold a professorship in physics.
