Answer:

Science advanced dramatically during the 20th century. There were new and radical developments in the physical, life and human sciences, building on the progress made in the 19th century.[1]

The development of post-Newtonian theories in physics, such as special relativity, general relativity, and quantum mechanics led to the development of nuclear weapons. New models of the structure of the atom led to developments in theories of chemistry and the development of new materials such as nylon and plastics. Advances in biology led to large increases in food production, as well as the elimination of diseases such as polio.

A massive amount of new technologies were developed in the 20th century. Technologies such as electricity, the incandescent light bulb, the automobile and the phonograph, first developed at the end of the 19th century, were perfected and universally deployed. The first airplane flight occurred in 1903, and by the end of the century large airplanes such as the Boeing 777 and Airbus A330 flew thousands of miles in a matter of hours. The development of the television and computers caused massive changes in the dissemination of information.

In the case of Schenck v. United States the Supreme Court ruled that _____
Sholpan [36]

Answer:

In Schenck v. United States, the Supreme Court ruled in 1919 that Schenck violated the Espionage Act. His campaign included printing and mailing 15,000 fliers to draft-age men arguing that conscription (the draft) was unconstitutional and urging them to resist. According to Schenck, conscription is a form of "involuntary servitude" and is therefore prohibited by the 13th Amendment. People were told to exercise their rights to free speech, peaceful assembly, and petitioning the government. Charles Schenck was imprisoned for expressing his beliefs after the court upheld the Espionage Act as constitutional. Schenck requested a new trial after he was convicted of violating the Espionage Act in 1917. He was denied the request. Afterward, he appealed to the Supreme Court, which agreed to review his case in 1919. This case later showed certain kinds of speech would be deemed illegal if it posed as a  threat to the US’s needs.
