Which 19th century paleontologist discovered and researched Jurassic period fossils in England? Getty Images Mary Anning Correct Incorrect Mary Anning Robert Ballard Correct Incorrect Robert Ballard John Hammond Correct Incorrect John Hammond Indiana Jones Correct Incorrect Indiana Jones Correct! Wrong! Mary Anning In 1811, Mary Anning thought she had found the skeleton of a crocodile, but it was actually an ancient fish-lizard that lived 200 million years ago. After teaching herself about geology, paleontology, biology and even scientific illustration, she discovered hundreds of fossils along the cliffs of the English channel.

Robert Oppenheimer Correct Incorrect J. Robert Oppenheimer Lise Meitner Correct Incorrect Lise Meitner Correct! Wrong! Lise Meitner As a Jewish woman trying to study physics in Germany, Lise Meitner had everything working against her. She was excluded from classrooms and laboratories, and she was forced to work in a basement before she eventually fled Nazi-controlled Germany. Despite all that, she led the team that discovered nuclear fission, paving the way for nuclear energy. Via Wikicommons / Getty Images Who coinedthe term "radiation"? Getty Images Enrico Fermi Correct Incorrect Enrico Fermi Marie Curie Correct Incorrect Marie Curie Werner Heisenberg Correct Incorrect Werner Heisenberg James Chadwick Correct Incorrect James Chadwick Correct! Wrong! Marie Curie Marie Curie investigated radioactive elements, and her discoveries led to a total reevaluation of the structure of the atom. She also discovered two chemical elements and was the first woman to be awarded a Nobel prize. Via Wikicommons / Getty Images Who discovered the structure of DNA? Getty Images James Watson Correct Incorrect James Watson Craig Venter Correct Incorrect Craig Venter Rosalind Franklin Correct Incorrect Rosalind Franklin Mario Capecchi Correct Incorrect Mario Capecchi Correct! Wrong! Rosalind Franklin While Rosalind Franklin was studying DNA, Maurice Wilkins–her lab colleague–reviewed her work and wrote his conclusions. Francis Crick published the discoveries in the scientific magazine Nature, and both scientists were awarded the Nobel prize in 1962. Sadly, Franklin passed away in 1958 before her contributions were widely recognized. Via Wikicommons / Getty Images Who refuted the hypothetical law of conservation of parity? Getty Images Chen-Ning Yang Correct Incorrect Chen-Ning Yang Tsung-Dao Lee Correct Incorrect Tsung-Dao Lee Chien-Shiung Wu Correct Incorrect Chien-Shiung Wu Gu Jing-Wei Correct Incorrect Gu Jing-Wei Correct! Wrong! Chien-Shiung Wu Chien-Shiung Wu contradicted a fundamental law of physics when she discovered that elementary particles know the difference between right and left (a huge oversimplification, but it's kind of the easiest way to explain it). Thanks to this discovery, two of her colleagues were awarded the Nobel prize, but Wu was not included in the nomination.

Martin Alexander Fleming Correct Incorrect Alexander Fleming E. O. Wilson Correct Incorrect E. O. Wilson Correct! Wrong! Gail R. Martin Stem cells are a type of cell that can replicate on any kind of tissue, and they're about to revolutionize medicine forever. Gail Martin was the first person to isolate and grow the cells in vitro. In a few years, when we are able to print human organs, you have her to thank.

Getty Images Louis Pasteur Correct Incorrect Louis Pasteur Jonas Salk Correct Incorrect Jonas Salk David Baltimore Correct Incorrect David Baltimore Françoise Barré-Sinoussi Correct Incorrect Françoise Barré-Sinoussi Correct! Wrong! Françoise Barré-Sinoussi During the AIDS epidemic in the 1980s, scientists were shocked because they didn't know what was causing the outbreak. Françoise Barré identified the human immunodeficiency virus as the origin of the disease and her discovery was essential for the development of newer and better treatments. Via Wikicommons / Getty Images Who discovered pulsars? Getty Images Jocelyn Bell Correct Incorrect Jocelyn Bell Carl Sagan Correct Incorrect Carl Sagan Neil DeGrasse Tyson Correct Incorrect Neil DeGrasse Tyson Stephen Hawking Correct Incorrect Stephen Hawking Correct! Wrong! Jocelyn Bell A neutron star is similar to the nucleus of an atom ... except that it's the size of Mount Everest and has the mass of three Suns. These super dense stars rotate at three times the speed of sound and emit intermittent light, radio waves, and very powerful electromagnetic radiation. Jocelyn Bell discovered these celestial bodies when she was only 24. Via Wikicommons / Getty Images Who discovered that the Earth has a solid core? Getty Images Charles Francis Richter Correct Incorrect Charles Francis Richter Inge Lehmann Correct Incorrect Inge Lehmann Alfred Wegener Correct Incorrect Alfred Wegener Socrates Correct Incorrect Socrates Correct! Wrong! Inge Lehmann Before Inge Lehmann, seismologists believed that the Earth contained only molten rock. In 1936, Inge discovered that at the center of the molten outer core was a solid inner core. Lehmann died at the age of 104, making her the longest living female scientist in history. Via Wikicommons / Getty Images Who discovered the genes for breast cancer? Getty Images James Watson Correct Incorrect James Watson Charles Darwin Correct Incorrect Charles Darwin Gregor Mendel Correct Incorrect Gregor Mendel Mary-Claire King Correct Incorrect Mary-Claire King Correct! Wrong! Mary-Claire King Among other things, Mary-Claire King is famous for her work in the field of genetics, and she was the first to prove that humans share 99% of their genome with chimpanzees. Her investigations into cancer has led to the detection and treatment of the disease in millions of patients. Via Wikicommons / Getty Images Who wrote the first computer program? Getty Images Ada Lovelace Correct Incorrect Ada Lovelace Tim-Berners Lee Correct Incorrect Tim-Berners Lee Steve Wozniak Correct Incorrect Steve Wozniak Mark Zuckerberg Correct Incorrect Mark Zuckerberg Correct! Wrong! Ada Lovelace Lord Byron's daughter was the first programmer ever ... way back in the 19th century! Without her, you wouldn't be taking this quiz right now.
