Transcript of Science and Technology of the 1920s

By Andrew Bear and Andrew Kolson Science and Technology of the 1920s Entertainment Radio was one the most popular forms of media during the 1920s. From 1922 to 1929 radio sales increased by $366 million. Science Albert Einstein was a theoretical physicist, famous for
developing the general theory of relativity, and the
famous mass energy equivalence formula, E = mc^2. Age of the Automobile The automotive industry boomed during the 1920s
due to an influx of money from World War I. Home Appliances As electricity started to enter more and more homes in the 1920s, home appliances began utilizing this new technology. Medicine In 1928, Alexander Fleming discovered the anti-bacterial fungus, Penicillin. This would later earn him a Nobel prize and become a common medicine. In 1927, the first science fiction film, Metropolis, was released, using the most advanced special effects of the time. Televisions also became commercially available during this decade. In 1928 John Baird released the first mass produced television, the Baird televisor. In 1920, there were 8 million registered vehicles in the country. By the end of the decade, this number almost tripled to 23 million. He was awarded the Nobel Prize in Physics in 1921 for "his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect." The 1920s also saw an increase in car manufacturers. Brands like Chrysler and Chevrolet emerged to compete with Ford. To help manage the number of new cars, the first widely used traffic light was created in Detroit Michigan, 1920. Due to the Federal Highway Act of 1921, many new gas stations were created across the country to supply the new automobiles. In 1921, Herman Rorschach published his
psychological ink blot test, in which subjects'
perceptions of inkblots are used in analyzing
their psychological condition. In 1921, two Canadian Scientists discovered the first successful treatment for diabetes, Insulin. Up until this point, there were no medical treatments available for diabetes. In 1924, a husband working for a medical gauze company put the gauze onto a piece of tape to create quick bandages for his accident prone wife. The company picked up on the idea and created the modern company BAND-AID. Inventions like electric washing machines, vacuum cleaners, and sewing machines began to emerge to make housework quicker and easier. More luxurious items such as the refrigerator were produced to feed the growing middle class. Both of these inventions changed family life in the 20s, as whole families would gather in the evening to watch the television or listen to the radio broadcasts. The inkblot test was important in changing the way
mental illnesses were thought of. Prior to this, popular
opinion was that they could not be cured, and the "crazy
people" would be locked up in asylums. Now, popular
opinion was that it was a condition that could be cured
through treatment.
