The Scottish physicist James Clerk Maxwell was the first to predict the existence of radio waves in the 1860s. Others, such as Marconi and Tesla, developed the transmitters and receivers that made radio possible. Radio wasn't originally conceived as an entertainment medium. Its purpose was for ship-to-ship and ship-to-shore communications using Morse code. At the turn of the 20th century, Marconi succeeded in sending a radio transmission across the Atlantic Ocean.

Florida officially became a state on March 3, 1845, and its first state flag was flown during the new governor’s inauguration. However, that flag was never made the official state flag because there was controversy surrounding the words “Let Us Alone†inscribed on the flag. When Florida seceded from the Union in 1861, many unofficial flags flew over the state. During 1861, Florida’s first official flag was documented by the secretary of state, but it is unknown whether this flag was ever flown over the Capitol. Later that year, Colonel William H. Chase took control of Pensacola Navy Ya..

The sophistication of Cro-Magnon hunting tools dictated what they could eat. One such tool, the spear thrower, increased the force and distance that Cro-Magnon hunters could launch their spears. This made it easier to bring down large mammals, such as mammoths, reindeer, red deer, roe deer, horses and cave bears. These animals began to disappear as Cro-Magnons became increasingly more efficient at hunting and killing large game. For example, by the end of the last ice age, 12,500 years ago, reindeer accounted for nearly 95 percent of all the large mammals that Cro-Magnons ate in what is now mo..

It is very difficult to compare modern journalists to the muckrakers. The muckraker journalist movement of the United States happened in the early 1900s during the Progressive Era. The reason these writers gained so much popularity is because they were published each month in magazines, and they clearly defined who the "villain" was, suggests Harvard's NiemanReports. Today, there is less of a national consensus on who the "villains" are, but nonetheless, many writers are calling for reform and progression in journals such as "The Nation" and "The Progressive."
