As American and British scientists worked collectively to meet the needs of the war, the large-scale production of penicillin became a necessity.
Men and women together experimented with deep tank fermentation, discovering the process needed for the mass manufacture of penicillin. In advance of the Normandy invasion in , scientists prepared 2.
From World War II to today, penicillin remains a critical form of treatment used to ward off bacterial infection. Penicillin Saves Soldiers Lives poster. Image courtesy of the National Archives and Records Administration, Of all the scientific and technological advances made during World War II, few receive as much attention as the atomic bomb.
Developed in the midst of a race between the Axis and Allied powers during the war, the atomic bombs dropped on Hiroshima and Nagasaki serve as notable markers to the end of fighting in the Pacific. While debates over the decision to use atomic weapons on civilian populations continue to persist, there is little dispute over the extensive ways the atomic age came to shape the twentieth century and the standing of the United States on the global stage.
Competition for dominance propelled both the United States and the Soviet Union to manufacture and hold as many nuclear weapons as possible. From that arms race came a new era of science and technology that forever changed the nature of diplomacy, the size and power of military forces, and the development of technology that ultimately put American astronauts on the surface of the moon.
The arms race in nuclear weapons that followed World War II sparked fears that one power would not only gain superiority on earth, but in space itself. During the mid-twentieth century, the Space Race prompted the creation of a new federally-run program in aeronautics. In the wake of the successful launch of the Soviet satellite, Sputnik 1 , in , the United States responded by launching its own satellite, Juno 1 , four months later.
From microwaves to space exploration, the scientific and technological advances of World War II forever changed the way people thought about and interacted with technology in their daily lives. The growth and sophistication of military weapons throughout the war created new uses, as well as new conflicts, surrounding such technology.
World War II allowed for the creation of new commercial products, advances in medicine, and the creation of new fields of scientific exploration. Almost every aspect of life in the United States today—from using home computers, watching the daily weather report, and visiting the doctor—are all influenced by this enduring legacy of World War II.
Kristen D. On April 21, , two political parties united, creating a single, dominant party in what became East Germany. By the time the Japanese attacked Pearl Harbor on 7 December , 20 radar units had been installed on selected ships. The radar units helped contribute to U. Development of the modern sonar began in the s when advancements in applying underwater sound to practical needs became abundantly clear.
During this time and with advances in electronics, depth sounding by ships and echo ranging on submarines was developed. Thomas Edison and other scientists became involved in the research of passive listening devices. Other researchers explored the physics of oceanography in which later work would be based. German submarines torpedoed Navy-escorted convoys at a record pace. At one point during the war, ships were being sunk faster than the U. Some of the ships were sunk within view of the U.
The mobilization of the U. Without the development of sonar, the U-boat threat would probably have never been contained. After the war, development of underwater detection devices continued.
By the end of the year, submarines could be detected several hundred miles away. That same year, Dr. Considered critical to national survival was the ability to transport people and goods across the high seas in the wake of the Soviet threat.
The committee recommended a long-term program needed to be formulated. The Hartwell Committee was formed to conduct the broad study. In the fall of , the Hartwell Committee recommended the development of nuclear powered submarines. It also recommended the detection of submarines using real time spectral analysis of radiated sound energy for the future of antisubmarine warfare.
The two most important factors in the development of sonar was the discovery that low-frequency sounds could travel great distances in the ocean, and the realization that submarines radiate identifiable low-frequency energy. The work of Bell Laboratories was also an important element. Experimental Pulse Radar Transmitter photographed at the U. Official U. First test of radar onboard a ship. Naval Research Laboratory in late While mounted on that ship, the experimental megacycle radar was tested at sea during the first months of The radar operator aboard a P5 Marlin patrol aircraft of Patrol Squadron 40 VP helps guide his aircraft towards an unidentified surface contact off the coast of Vietnam, June National Archives photograph, USN National Archives photograph, K A Navy frogman tests new sonar equipment developed to located underwater objects.
The lightweight, portable, diver-held sonar system is economically powered by standard flashlight battering. Earphones provide the diver with audio information of objects by the searching sonar beam, 5 May A controlman monitors a radar console in the radar room at Chambers Field, 17 January First Rotating Beam Radar megacycle radar used for transmitting and receiving developed by the U.
Naval Research Laboratory in This view shows the antenna installed topside on a NRL building in Anacostia, District of Columbia, at about that time. This was a so-called 'dirigible' antenna, meaning it is mounted so that it can be turned to allow for around-the-compass search. Semkin and Apprentice Seaman G.

Clark assists in procurement, analysis, evaluation, and distribution of sonar recognition group training materials. Looking aft, to the right are the depth gauges and the plane wheels, which are rigged out. All gauges are lit. The museum was attempting to get a better "blip" target indication on the sonar.

Manufacturing penicillin for soldiers was a major priority for the U. Military surgeons were amazed by how the drug reduced pain, increased the chance of survival and made it easier for nurses and doctors to care for soldiers on the battlefield. The United States considered the drug so critical to the war effort that, to prepare for the D-Day landings , the country produced 2.
After the war, civilians gained access to this life-saving drug, too. The first jet propulsion engine designed by Frank Whittle, c. In May the jet-propelled craft took off from Cranwell in the first real proof that jet propulsion was a viable alternative to the propeller. Frank Whittle, an English engineer with the Royal Air Force, filed the first patent for the jet engine in But the first country to fly a jet engine plane was Germany, which performed a flight test of its model on August 27, , just a few days before the country invaded Poland.
The first Allied plane to use jet propulsion took flight on May 15, Jet planes could go faster than propeller planes, yet also required a lot more fuel and were more difficult to handle. Medics tending to a wounded soldier on D-Day, administer a blood plasma transfusion. Colossus was the world's first electronic programmable computer at Bletchley Park in Buckinghamshire, where cryptographers deciphered top-secret military communiques between Hitler and his armed forces.
During World War II, the United States began to develop new machines to do calculations for ballistics trajectories, and those who had been doing computations by hand took jobs programming these machines.
