The light bulb

Image: Zach Lucero

Delivering electricity to the masses was one of the greatest technological advances in human history. The mid-1800s saw great competition in this area, as inventors around the world raced to invent their own electric light. The first filament bulb was developed by British inventor Warren de la Rue in 1840, but his use of a platinum filament made it expensive and impractical.

A few years later, Joseph Swan in the UK and Thomas Edison in the US each independently invented bulbs using cheaper elements. However, Edison received a patent on his bulb in early 1880, slightly before Swan. The light bulb, an invention that quickly reached every home, revolutionized life around the world, led to the development of the electrical grid, and set the stage for our modern electricity-dependent society.

The telephone

Image: viarami

In this modern era of emails and text messages, it can be hard to appreciate that the telephone was once revolutionary. The telegraph, the phone’s predecessor, only transmitted brief written messages. The telephone, however, allowed people to speak with one another in real time over long distances.

Inventor, scientist, and engineer Alexander Graham Bell invented the electric telephone in 1876. Although Bell was Scottish-born and also lived in Canada, he patented his invention in the US . The telephone was a game-changing technology that improved business efficiency, enabled instant global connections, and allowed emergencies to be reported as they occurred. It effectively made the world more connected and faster-paced.

The fire escape

Image: Lewis J Goetz

When we think of US inventions, the first things that come to mind are usually the light bulb or the telephone. But did you know that the modern fire escape was also a US innovation? Designed in 1887, this simple yet life-saving invention changed building safety forever.

In the late 1800s, fires were devastating cities across America. One woman, Anna Connelly, saw this horror up close and decided to do something about it. She designed an external iron staircase system, and in 1887, she patented it. At a time when women couldn’t even vote, Anna’s invention became a safety standard in most major cities, saving thousands of lives. Today her name is barely known, but next time you see a fire escape, remember the woman who made them possible.

The cash register

Image: Di Du

The first mechanical cash register for calculating and recording sales transactions was invented by saloonkeeper James Ritty following the American Civil War. He was looking for a way to stop cashiers from stealing, and finally patented his novel invention in 1879.

When a transaction was completed, Ritty's Incorruptible Cashier made a bell sound, and the amount was displayed on a large dial on the front of the machine. During each sale, a paper tape was hole-punched so the vendor could keep track of sales. Pretty ingenious, don’t you think?

Interchangeable parts

Standardized interchangeable parts for machines are now a staple of modern manufacturing, but it’s not a new idea. There’s evidence that thousands of years ago, ancient Carthage used them to build warships, and ancient China applied the idea to crossbows. Many centuries later, French experimentation with interchangeable musket parts inspired Thomas Jefferson.

In 1798, President George Washington and his Congress finally agreed to Jefferson’s idea of implementing the technology in America. They awarded a contract to Eli Whitney—the inventor of the cotton gin—to supply the government with 20,000 muskets. Whitney recognized the potential of developing firearms with identical parts and mechanisms. His advancements in interchangeable parts laid the foundation for modern manufacturing, enabling improved quality control, reduced costs, and faster production of goods.

The assembly line

For most of human history, manufactured goods were custom-made. Every model of a machine, piece of clothing, or tool was unique. The development of interchangeable parts was a huge advancement, but automobile manufacturer Ransom Olds took it a step further with the assembly line in 1901. By standardizing and automating many aspects of manufacturing, uniform goods could be created faster and at lower costs.

Olds’ vehicle, the Oldsmobile Curved Dash, became the first mass-produced car . His method was later adopted and perfected by Henry Ford, whose moving assembly line for the Model T in 1913 revolutionized manufacturing. Today, the assembly line combines human labor and automation to produce nearly every mass-market product on Earth. Many experts agree it was one of the most significant technological developments of the 20th century.

The airplane

People have always observed birds and insects and dreamed of flying. The Greeks told the story of Icarus and Daedalus, who crafted wings of wax and feathers; Leonardo da Vinci sketched and theorized flying machines, but it wasn’t until 1903 that the airplane became a reality in Kitty Hawk, North Carolina.

Wilbur and Orville Wright experimented with aeronautics for several years before achieving their successful first flight. A few years later, airplanes were first used in warfare. Within seven decades, their technology evolved and took us to the Moon. Today, the airplane is an indispensable technology that allows us to transport goods and people around the world in no time.

GPS

It’s hard to imagine life without GPS—but do you know how it began? When the Soviet Union launched Sputnik in 1957, American physicists realized they could track the satellite’s radio transmissions using the Doppler effect.

Soon after, the U.S. military began testing and launching the Navstar Global Positioning System satellites. In 1983, President Ronald Reagan approved GPS for civilian use, and by the start of the 21st century, GPS devices were widely available in vehicles and mobile phones . Today, GPS is an essential technology for business, travel, and military operations.

Personal computers

The first electronic general-purpose computer, ENIAC, was built in 1946 at the University of Pennsylvania. It occupied 1,800 square feet of floor space and weighed 30 tons. At the time, imagining a consumer-grade computer small enough to fit in every home would have seemed impossible. Yet, just one generation later, the impossible became reality.

Over the years, computers became smaller, cheaper, and more powerful than the ENIAC’s creators could have imagined. In 1971, John Blankenbaker developed the first PC, the Kenbak-1. Fifty years later, it is clear that personal computing has fundamentally shaped the modern world.

The internet

Image: Lorenzo Herrera

Revolutionary technologies such as the wheel, the internal combustion engine, the telephone, and the airplane have forever changed the way we travel and communicate. The internet is no exception; it gives people access to the entirety of human existence with just a few clicks.

In 1969, computer scientists at the Advanced Research Projects Agency (ARPA) created the first network connecting labs at UCLA and Stanford. Over time, their network expanded, connecting anyone with a device. Since then, the internet has revolutionized the way human beings access resources and share information.

E-mail

After the personal computer and the Internet, we only needed to invent a modern method of sending messages and letters to each other. The Advanced Research Projects Agency Network, known as ARPANET, sent the first email in 1971. Within five years, the majority of exchanges within the ARPANET community were via email.

With the introduction of attachments in the early 1990s, electronic mail became the fastest and easiest way to send information from point to point. By the start of the 21st century, email enabled people around the world to communicate quickly and inexpensively, and the technology quickly became one of the primary tools for global communications.

Magnetic resonance imaging

The impact of the MRI machine on medicine is invaluable. The principles behind nuclear magnetic resonance (NMR) have been known since at least the end of World War II. Yet, two researchers in the late 1960s and early 1970s recognized the potential of this technology to revolutionize medicine forever.

American chemist Paul Lauterbur and physician Raymond Damadian separately experimented with NMR in scanning for cancer cells. After publishing the promising results of their experiments, a patent was filed. By 1977, the first full-body scanner was developed. Since then, millions of lives have been saved by the MRI machine. For his contributions, Lauterbur was awarded the Nobel Prize in Physiology or Medicine in 2003.
