The Humble Beginnings of the Wheel [1:33]
The wheel, one of history's oldest technological devices, has played a key role in many of society's greatest inventions. First seen around 3000 BC in Mesopotamia, the wheel and axle combo enabled efficient crop transport, boosting city populations. Even earlier, around 8000 BC, rotary motion was used in flywheels and pulleys for lifting heavy stones, aiding city construction. Water wheels generated early power, and rotating gears became essential in tools and machinery, sparking the Industrial Revolution.
The Steam Engine: From Toy to Transportation Revolution [3:08]
The steam engine propelled the world into a new age of transportation. While James Watt is often credited, the power of steam was known long before. Hero of Alexandria created a rotating steam turbine wheel around 100 AD, but it was dismissed as a toy. Thomas Newcomen designed a practical atmospheric steam engine around 1712 to pump water out of mines. James Watt improved it by applying steam to both sides of the piston, enabling regular rocking motion and wheel rotation. This led to the steamship, man's first major development in long-distance travel since the sail. Robert Fulton's steamship, the Claremont, achieved commercial success in 1807, traveling between New York and Albany.
Railroads and Automobiles: Revolutionizing Land Transport [5:52]
The steam engine led to the railroad, connecting communities worldwide. Early railroads were animal-powered, but steam power made it more efficient to pull heavier loads. The transcontinental railroad in the 1860s tied America together. Railroads became the dominant mode of freight, shipping, and transportation, giving people unprecedented mobility. As steam power dominated transport, inventors sought more efficient means, leading to the automobile. Early automobiles used steam engines but were slow and uncomfortable. Carl Benz is credited as the father of the automobile for developing and marketing gasoline-powered road vehicles. Henry Ford revolutionized the industry with his Model T, a cheap and good car for the masses, produced using the assembly line process inspired by meat packing industries.
Ford's Assembly Line and the Rise of the Automobile [9:17]
Ford's assembly line drastically reduced the Model T's price, making it accessible to the public. By 1920s, the price of Model T dropped from $850 to $260. By 1927, 17 million Model Ts had been produced. The automobile reshaped the landscape, leading to the interstate highway system and the decline of railroads. With nearly 300 million cars in the US alone, the automobile has forever altered transportation.
Harnessing Electricity: From Amusement to Power [11:41]
While the wheel was a product of accidental discovery, the study of electricity was a result of scientific research. Ancient Greeks knew amber created a magnetic force when rubbed, but didn't know how to harness it. Benjamin Franklin proved electricity was in lightning with his kite experiment in 1752 and invented the lightning rod. Inventors then developed the battery to store electricity.
The Battery and the Telegraph: Instant Communication [13:37]
The battery provided the basic building block for experimentation in telegraphy and wireless telegraphy. A crude form of battery may have existed in the 1st century AD, but the first authentic battery was created in the early 1800s by Alessandro Volta. The battery fueled major advances in instantaneous communication. The telegraph, based on the battery and electromagnet, allowed instantaneous communication for the first time. Samuel Morse sent the first telegraph message in 1844, "What hath God wrote?".
The Telephone: Putting Words into Communication [18:02]
Alexander Graham Bell invented the telephone, initially called a "speaking telegraph". He discovered electrical currents could duplicate sound waves. In March 1876, Bell sent the first human voice message over telegraph wire to Watson, "Come here, I want you." Western Union initially refused Bell's offer to sell the telephone patent, but later reconsidered.
The Light Bulb: Illuminating the World [20:04]
Stronger currents of electricity led to more great inventions, including the light bulb. Thomas Edison succeeded in creating a viable light bulb. Edison found that a thin piece of carbon heated by electric current glows brightly. The invention of the electric light bulb in 1879 profoundly changed society. Edison also laid the groundwork for a complete electric light and power distribution system. The light bulb changed work, play, and home life dramatically.
Radio and Television: Mass Communication Takes Off [23:38]
Edison's light bulb led to the electronics industry. An Italian inventor named Maronei developed the vacuum tube, which became an efficient way of detecting and producing radio waves. Radio brought a world of information and entertainment into the home. Gulmo Maronei demonstrated that radio waves would travel through the air. By the 1920s, radio became a cultural phenomenon. Scientists then wondered if they could send visual images, leading to television. Television technology continues to advance at an astonishing rate.
The Transistor: Shrinking Technology and the Computer Age [29:49]
In 1948, the transistor was invented at Bell Labs. The transistor amplified electrical signals in a fraction of the space, scaling everything down to size. Transistors were less expensive and more reliable than vacuum tubes. The transistor played a key role in the development of the computer. The integrated circuit or chip contains millions of transistors on a single chip.
The Computer: From Mechanical Calculators to Global Impact [32:04]
Early forms of computers were created by Blaise Pascal in 1645. Charles Babbage is known as the father of computing for his work on a mechanical device resembling today's computers. Herman Hollerith created a punchcard computing machine to aid in the 1890 census. In 1924, the Computing Tabulating Recording Company changed its name to International Business Machines Corporation (IBM). The first automatic digital computer was the ENIAC, funded by the US Army in 1943. The computer has forever changed the way we live and work.
The Microscope: Unveiling the Microscopic World and Saving Lives [36:50]
The microscope has led to the greatest advances in modern medicine. Scientists were able to detect and defeat deadly bacteria with the microscope. Galileo improved the microscope, making flies look as big as a lamb. Scientists uncovered life-saving discoveries, including vaccines, with the aid of the microscope. Vaccines are designed to introduce a bit of the disease into the body without actually passing on the disease itself. Edward Jenner created the first successful immunization against smallpox in 1796.
Vaccines, Antibiotics, and the Fight Against Disease [39:29]
Louis Pasteur made great strides in vaccine research, developing a rabies vaccine. Alexander Fleming discovered penicillin in 1928, which led to great strides in the war on bacteria. The electron microscope allowed the magnification of viruses. Jonas Salk's research led to the creation of a vaccine that virtually eradicated polio. Vaccines help us live longer than at any other time in history. Key inventions have affected and influenced every aspect of our lives. The amount of technologies that are coming together and being utilized together is leading to advancements unparalleled in any part of history. As long as man continues to think, he will continue to invent.
