- The Wheel.
The proverb ‘There’s no need to reinvent the wheel’ underscores the monumental significance of this creation from around 3500 BC.
The invention of the wheel was a transformative moment in human history, particularly for long-distance cargo transportation.
The most remarkable aspect was not the creation of the wheel itself, but the ingenious wheel-and-axle arrangement that connected a stationary platform to a revolving cylinder, revolutionizing transportation.
- Press for Printing.
The printing press, a revolutionary invention by Johannes Gutenberg in 1440 CE, had a profound impact on the spread of knowledge, surpassing any other technology before the internet.
Gutenberg, a German inventor from Mainz, enhanced an existing machine by using a mold to produce lead alloy-like bits rapidly, thereby revolutionizing the dissemination of knowledge.
- The Third Compass Image.
The invention of the compass was a turning point in the history of nautical navigation, benefiting sailors worldwide. Before its creation, navigators could only use a method restricted to clear nights: relying on the stars.
The Chinese created the first compass between the ninth and eleventh centuries. It was made of lodestone, an inherently magnetic iron mineral. Lodestone changed maritime navigation by offering a dependable way to get your bearings day or night.
- The Antibiotic Penicillin.
Without discussing Penicillin, no overview of innovations that influenced human history would be complete.
Scottish scientist Alexander Fleming found a mold in a Petri dish in 1928 that appeared to eradicate the microorganisms around it. The mold proved to be Penicillin, an antibiotic that would transform medicine by successfully battling.
- The Image of the Telephone.
In 1876, Scottish inventor Alexander Graham Bell received a patent for the electric telephone due to his experiences with his mother, who was hard of hearing. Bell’s creation revolutionized international trade and communication, making it easier for people to connect over long distances.
It established the groundwork for contemporary telecommunications, paving the way for the global communication networks we have today. Even though phones nowadays are significantly more sophisticated, it’s unlikely that Bell would recognize his groundbreaking invention in its current incarnation.
- The Light Bulb.
The light bulb, which Thomas Edison is credited with creating in 1879, has illuminated homes and workplaces worldwide. Its invention allowed for previously unheard-of productivity levels after dark, transforming the way people worked and lived.
Edison’s invention made electricity widely available in homes, changing how people slept and worked. Electric bulbs enable people to work and be productive even after the sun sets, a concept that was previously unimaginable.
- The Image of the Nail.
The nail was created more than 2,000 years ago during the ancient Roman era. These straightforward yet useful tools became indispensable in building as people mastered the art of casting and shaping metal, aiding the Romans in creating their revolutionary civilization.
Up until 1913, iron nails were widely used in buildings. However, steel wire accounted for 90% of the nails produced in the United States at that time.
