Science and Technology 1900 to Present - AP World History: Modern

James Watson and Francis Crick used X-ray images created by Rosalind Franklin to discover that the structure of DNA was a double helix. This discovery showed how DNA replicated itself and furthered our understanding for how genetic traits were passed from one generation to the other.

World War One was a period of great innovation in weaponry and warfare. Tanks, poison gas, trench warfare, and submarine warfare were all used for the first time during World War One. However, replaceable parts were invented more than a century earlier and were used for the first time in the Napoleonic Wars of the early nineteenth century.

It is estimated that the global population of internet users is approximately three billion. Approximately forty percent of the global population has regular access to the internet.

Penicillin was invented by Alexander Fleming in 1928. It is an antibiotic that fights against bacterial infections. The invention of penicillin, and other antibiotics, dramatically improved mankind’s ability to resist and fight back against deadly diseases.

The invention of penicillin, by Alexander Fleming in 1928, allowed humans to fight back against bacterial infections with potency for the first time in human history. Penicillin, and other antibiotics, fight diseases that have historically devastated human populations, especially during times of war. The use of penicillin in World War Two dramatically reduced the number of casualties from diseases like influenza.

Alexander Fleming is widely credited with the discovery, and his work earned him the Nobel Prize. Marie Curie was also a scientist, however she is most famous for her experiments with radiation. Mendeleev was a chemist himself, however he is most famous for developing the periodic law, which led to the periodic table. Aristotle was an ancient Greek philosopher and naturalist, however he lived far before the discovery of penicillin. Lastly DaVinci, while also a famous inventor and thinker, was similarly dead long before the discovery in question.

The Manhattan Project was a secret American military project that led to the creation of the first atomic bomb in 1945. It was led on the civilian side by physicist Robert Oppenheimer, and on the military side by General Leslie Groves. The Manhattan Project created the two atomic bombs that were dropped on the Japanese cities of Hiroshima and Nagasaki at the end of World War II in 1945.
