Invented in 1973: A Look at Some of the Most Iconic Inventions

The Year 1973

The year 1973 was a significant year in modern history. It was a year of great change and progress in multiple fields. The Vietnam War ended, and the Watergate scandal broke out, leading to the resignation of President Richard Nixon. In the world of technology, 1973 saw several inventions that changed the course of history.

The Pager

The first pager was invented in 1973 by Motorola researcher, Dr. Martin Cooper. It was named the Motorola Pageboy and was a small, handheld device that could receive short messages. This was a revolutionary invention, as it was the first time people could communicate with someone who was not physically present in the same space. Pagers soon became widespread, and they were popular among doctors and emergency services as a way to keep in touch while on the go. Even though pagers are no longer in use, they paved the way for revolutionary changes in the field of communication.

The Ethernet

The Ethernet was also invented in 1973 by Robert Metcalfe, who was working at Xerox's Palo Alto Research Center (PARC). The Ethernet is a local area network (LAN) technology that allows computers to communicate with each other over a shared cable. It was initially created to help PARC connect its computers, but it soon became the industry standard for LANs. Ethernet made it possible for computers to share information and resources, paving the way for the internet as we know it today. Ethernet is still widely used today, and it has been constantly evolving to keep up with the ever-increasing demand for connectivity.

The Cellphone

Although the first cellphone was not commercially available until 1983, the development of the technology began with the invention of the mobile phone by Martin Cooper, who also invented the pager. He made the first mobile call on a prototype Motorola phone in 1973. The first cellphone was large and bulky, but it revolutionized the way people could communicate with one another. The cellphone paved the way for future developments in communication technology, including smartphones that provide access to the internet, cameras, and many other features.

The Rubik's Cube

The Rubik's Cube is a 3D puzzle that was invented by Hungarian sculptor and professor of architecture Erno Rubik in 1974. Although it was not invented in 1973, it gained significant popularity during that year when it was first presented to the public. The Rubik's Cube is widely considered one of the best-selling toys of all time, and it has been a cultural icon for several decades. Solving the Rubik's Cube requires a combination of intelligence, strategy, and perseverance, and it has become a popular hobby for millions of people worldwide.

Conclusion

Overall, the year 1973 was a year of great significance in modern history due to the invention of several iconic items that revolutionized the world. The pager, Ethernet, and cellphone paved the way for modern forms of communication, while the Rubik's Cube earned a place in popular culture. These inventions continue to evolve and shape the world in new and exciting ways, highlighting the importance of innovation and progress in our society.

Innovations in the Medical Field

The CAT Scanner

The first computed tomography (CT) or computerized axial tomography (CAT) scanner was invented by Sir Godfrey Hounsfield in 1973. This invention changed the medical field forever by revolutionizing medical imaging and diagnosis. Before the CT or CAT scanner, traditional X-rays would produce images of bones and other dense structures in the body. However, these images would not provide a clear picture of internal organs.

With the CT or CAT scanner, doctors could finally get a detailed look at internal organs, tissues and blood vessels, making it easier to diagnose diseases and injuries. Cross-sectional images of the body could be generated through a series of X-rays taken from different angles, manipulated by a computer, and producing detailed images without the need for exploratory surgery.

The CAT scanner is still in use today, but the technology has improved, and the machines have become smaller and faster, requiring less exposure to radiation and taking less imaging time.

The Automated External Defibrillator

The Automated External Defibrillator or AED is a lifesaving invention that has been saving lives around the world since 1973. The AED was invented by Dr. Michel Mirowski, and it's a portable electronic device that can diagnose life-threatening cardiac arrhythmias and restore the heart to its normal rhythm.

The AED works by assessing the heart rhythm and delivering a shock to the heart to restore or reset the heartbeat. This shock is delivered by large electrodes that are placed on the patient's chest. The AED device is easy to use, and it provides step-by-step instructions for the rescuer, allowing anyone to treat a victim of sudden cardiac arrest.

The AED is now commonly found in airports, malls, and other public places and has become an essential life-saving device, preventing fatalities due to sudden cardiac arrest.

The Drug Delivery System

The invention of the drug delivery system in 1973 allowed drugs to be released slowly over time into the bloodstream. This innovation revolutionized the way drugs were administered, making it easier to manage chronic illnesses such as diabetes, hypertension, and asthma.

Before the drug delivery system, drugs needed to be administered through injections, making it difficult for patients to self-administer. Now drugs can be administered through various mechanisms such as inhalers, transdermal patches, and implantable devices, providing patients with pain-free and convenient treatment.

The drug delivery system also has the added advantage of reducing the side effects and toxicity of drugs, as it releases the drug at a controlled pace and allows for targeted delivery.

In conclusion, the inventions of the CT or CAT scanner, AED, and drug delivery system were game-changers in the medical field. These innovations have significantly impacted the diagnosis, treatment, and management of diseases and are still in use today - a testament to their value and effectiveness.

Inventions That Changed Our Lives in the 70s

The Floppy Disk

The floppy disk was invented in 1971 and became commercially available in 1973. This technology made data storage more accessible for the average computer user. Before the floppy disk, data was stored on large and expensive hard drives that were only available to large organizations and government agencies. The floppy disk was a portable and cost-effective solution to store data. It could hold up to 1.44 megabytes of data, which was a significant amount at the time. It was the primary storage medium for personal computers until the early 2000s when USB drives took over.

The floppy disk revolutionized the way people use computers. It allowed users to easily save and transfer files from one computer to another. With the introduction of the floppy disk, people no longer had to rely on paper records or other methods of data storage. The accessibility and affordability of floppy disks made it possible for more people to use computers in their daily lives.

The Digital Watch

The digital watch was invented in 1972 and became mainstream in the mid-1970s. The emergence of the digital watch had a significant impact on the watch industry. Before the digital watch, watches were entirely mechanical. Digital watches use electronic displays, making them more accurate and reliable. The digital watch also introduced features such as alarms, timers, and stopwatches.

The rise of the digital watch led to a decline in sales of traditional watches. The watch industry had to adapt to keep up with the changes in consumer preferences. Watchmakers began producing hybrid watches that combined the accuracy of digital watches with the elegance of traditional watches. The digital watch paved the way for modern smartwatches, which have become popular in recent years. The digital watch made timekeeping more convenient and accurate and influenced the evolution of modern watches.

Post-it Notes

Post-it Notes were invented by accident in 1974 by Spencer Silver, a 3M scientist who was trying to develop a strong adhesive. Instead, he created a low-tack, reusable adhesive that covered surfaces without damaging them. Silver's invention attracted the attention of fellow 3M scientist Art Fry, who was struggling to mark his choir hymnal without damaging the pages. Fry realized the adhesive could be used for this purpose and began using it to mark his hymnal pages.

The Post-it Note was born, and it quickly became a popular way to mark pages in books and documents. The convenience of easily attaching and removing Post-it Notes without causing damage made them a staple in offices and homes around the world. Post-it Notes have become an essential tool for brainstorming, taking notes, and organizing information. They have even inspired a range of office accessories, including Post-it Note dispensers and organizers.

In 2016, 3M celebrated the 35th anniversary of the Post-it Note, and today they continue to be a popular and useful invention.
