relating to the first two decades of the Twenty-first.
We researched several websites and found that a lot of things happened from 1900 to 1910, inclusive. From the frivolous to the profound, some of the inventions and advances still affect America and the world today. In 1905, the American form of football allowed the forward pass to stop injuries and deaths caused by brute-force tactics such as the “flying wedge.” Today, the National Football League is trying to make reforms that will minimize, or do away with concussions. Also in 1905, Albert Einstein published a paper introducing the idea that the formula for determining energy is a direct ratio with the combined characteristics of mass and the speed of light squared, e=mc2. In that same year, he published a fuller elucidation, his theory of relativity. (We felt like we could use phrases like “fuller elucidation” when we’re talking about such heady stuff.) From those papers have risen arsenals, energy generation, medical uses of radiation, and advances in the physics that run our televisions and computers, among other things.
Speaking of televisions and computers, both of these have their roots in Lee De Forest’s invention of the vacuum tube triode in 1907. “The three terminal setup could serve as an electrical switch. When you changed the voltage traveling to one terminal, you could reduce the current following between the other two terminals. In this way, you could turn it ‘on’ and ‘off.’ That's your 1 and your 0,” says Wired.com in reference to the binary code used in programming.[1]
The more immediate use of the vacuum tube was in building the sets needed to receive that new-fangled thing called radio. De Forest used his vacuum tube to transform “those taps and clicks [of Marconi’s wireless telegraph transmissions] into the broadcast communication system we know today,” according to Wired, adding, “Forest, who also coined the name ‘radio,’ used his invention to send the first over-the-air public broadcast on January 12, 1910.”
From all this, it becomes apparent that first decade of the twentieth century saw the new arrivals of more than twenty inventions that reshaped life and business. Mercedes (1901) and Ford (1908) took the automobile from the showcase and exhibition track to the roads of America and Europe in mass numbers. Along the way, they also invented the car salesman.
These inventions made their creators wealthy through marketing. In
