Technologies don't just change how we live; they change who we are and how we relate to the world around us.
1. Timekeeping has shaped our daily lives and work habits
The way humans measure time has evolved greatly, from rudimentary sun dials to highly precise quartz clocks. Elizabeth Ruth Naomi Belville, known as the Greenwich Time Lady, made her living in 19th century England by synchronizing clocks to Greenwich Mean Time using her pocket watch, Arnold. While this might seem outdated today, it highlights just how obsessive humans became about keeping accurate time as societies industrialized.
The invention of the quartz clock in the 20th century further refined accuracy. Quartz vibrations—100,000 per second when exposed to electricity—offered unparalleled precision. This technological leap coincided with the rapid industrialization of America during the 19th century. Factories depended on accurate timekeeping to standardize work hours, synchronize production runs, and enforce punctuality on workers.
Over time, the strict enforcement of clock time influenced all areas of society. "Time is money" became a mantra that prioritized productivity above all else. However, this relationship with time has contributed to modern issues such as sleep disorders, affecting both how we live and how we rest.
Examples
- Belville's "Arnold" served as a portable source of Greenwich Mean Time.
- Quartz clocks, invented in 1927, revolutionized how time was measured.
- Industrialization led to individuals’ daily routines being dictated by factory schedules.
2. Steel and railroads transformed distances and economies
In 1855, the invention of steel-making technology by Henry Bessemer revolutionized industries. By introducing air to molten pig iron to remove impurities, Bessemer created steel, a much stronger and more durable material than iron. Steel railroads drastically reduced perceived distances, enabling faster transportation and communication.
The mass production of steel rails made it possible for railroads to expand rapidly across the United States. By 1900, steel rails could theoretically circle the world ten times. This new infrastructure not only connected cities but also reshaped commerce by enabling the transportation of goods and people in ways that were previously unimaginable.
The integration of steel railroads also had cultural consequences. Holidays like Christmas were transformed into gift-giving occasions as products could now move quickly across the country, supporting economic growth and cementing consumerism as part of American life.
Examples
- Bessemer's process turned pig iron into steel by blowing air through molten metal.
- By 1900, steel tracks revolutionized America's railroads, bridging enormous distances.
- National holidays like Christmas became commercialized due to increased product circulation.
3. The telegraph reshaped language and community
The telegraph, developed by Samuel F.B. Morse in the mid-19th century, accelerated communication to unprecedented levels, sidestepping the grueling pace of traditional mail systems. It used electrical pulses to send messages across wires, which were decoded into combinations of dots and dashes.
The invention not only sped up the spread of information but also changed how people expressed themselves. Limited transmission time forced journalists to adopt concise, clear styles, laying the groundwork for a uniquely American form of writing. Ernest Hemingway, for example, carried this style into fiction, favoring brevity and simplicity.
On a larger scale, the telegraph united previously isolated communities. Towns far apart could now share news in real time, creating a deeper sense of connection and fostering a shared national identity. It shaped how Americans thought, spoke, and wrote.
Examples
- The telegraph allowed Morse to send the inaugural long-distance message in 1844.
- Writers like Hemingway adopted styles influenced by telegraph brevity.
- Rural communities felt more connected once telegraph communication became widespread.
4. Photography mirrored societal biases
Though photography promised to record life truthfully, it reflected societal biases instead. Frederick Douglass, a 19th-century abolitionist, celebrated the daguerreotype for its lifelike detail and thought it could challenge harmful stereotypes. Despite his optimism, biases crept into photographic technology over time.
In the 20th century, Kodak designed its film to privilege lighter skin tones, which marginalized and misrepresented darker-skinned people. Protests eventually led to improved film formulations, but the delay revealed that photography carried the prejudices of its makers. Meanwhile, Polaroid's involvement in apartheid South Africa, producing passbooks for black citizens under oppressive control, highlighted how technologies could actively enable injustice.
Activists like the Polaroid Revolutionary Workers Movement (PRWM) used social pressure to hold companies accountable. Technologies that initially seemed neutral often had real-world impacts shaped by human intent and culture.
Examples
- Frederick Douglass saw early photography as a tool to combat stereotypes.
- Kodak optimized its film for white skin, ignoring complaints from African-American communities.
- The PRWM brought attention to Polaroid’s involvement in apartheid, leading to its withdrawal.
5. Electric light introduced unintended consequences
The invention of the light bulb by Thomas Edison transformed the night into an extension of the day. Carbon filaments inside oxygen-free glass bulbs created safer, longer-lasting alternatives to candlelight or gas lamps, redefining nightlife and work hours.
However, electric light has disrupted our natural rhythms. Too much artificial light prevents our bodies from producing sufficient melatonin, a hormone that governs sleep and repair processes. Researchers have linked light exposure at odd hours to increased cancer risk, suggesting that constant illumination might harm long-term health.
Adopting healthier habits, such as dimming lights in the evening and embracing more natural light in the mornings, might help mitigate these effects. The invention that so successfully illuminated the world has also illuminated the challenges of overuse.
Examples
- Edison improved on arc lighting systems by using a carbon filament in a vacuum.
- Artificial light inhibits melatonin production, throwing off sleep cycles.
- Epidemiological studies suggest blind women have lower cancer rates, possibly due to light exposure differences.
6. Sound recording changed how we store and share information
Thomas Edison’s phonograph, invented in 1877, marked the first time sound could be captured and replayed. Though rudimentary at first, recording technology advanced rapidly. Over time, music shifted from ephemeral live performances to collectible recordings.
This progression wasn’t limited to music. Digital recording systems like hard disks and the cloud enabled the mass storage and sharing of other data, from personal photos to entire libraries of information. Today’s ability to share data globally stems from early innovations in recorded sound.
The flip side is that personal data is now a commodity. Media platforms track everything from your listening habits to your location, raising ethical concerns about privacy in the digital age.
Examples
- Edison’s phonograph could only record a few seconds of sound, but it revolutionized communication.
- Digital recordings transformed sound waves into data, enabling internet music streaming.
- Streaming platforms gather extensive personal information based on listener behavior.
7. Specialized glass enabled technological breakthroughs
Before the late 1800s, glass was inconsistent in quality. German chemist Otto Schott revolutionized glassmaking by introducing precision and specialized formulations. His work improved optics in telescopes and microscopes, which expanded scientific exploration.
Later, American companies like Corning Glass Works developed new types of glass, such as Pyrex, which were essential for advancements in science and industry. Improved glass materials allowed for clearer medical imaging, deeper space telescopes, and more reliable laboratory experiments.
The role of glass in scientific discovery cannot be overstated—it’s been the silent partner in experiments from X-rays to the discovery of electrons, enabling us to see and understand what was once invisible.
Examples
- Schott collaborated with physicist Ernst Abbe to improve the glass used in telescopes.
- Corning created Pyrex, which became essential for chemical experiments.
- Transparent glass enabled cathode ray experiments, leading to the discovery of electrons.
8. Digital tools are rewiring human thought
The internet has given us access to vast amounts of knowledge but has changed how we think. While it’s improved problem-solving and broadened perspectives, it’s also shortened attention spans and fragmented communication.
Experts observe that we now rely less on memory and more on digital storage—for instance, knowing where to find information rather than memorizing it. Smartphones allow us to focus on convenience, but at the cost of deeper understanding.
This raises philosophical questions about the trade-offs between human intelligence and machine efficiency. To what extent should we rely on technology when it may erode key cognitive abilities?
Examples
- Neuroscientist David Eagleman attributes higher IQs to access to more ideas.
- Nicholas Carr critiques the internet for superficial reading and scatterbrained habits.
- Digital tools have replaced memorization with quick searches, altering what we value intellectually.
Takeaways
- Create "light hygiene" by using dim lighting at night and brighter natural light during the day to support healthier sleep cycles.
- Balance information consumption by taking breaks during online browsing to reflect and engage in deeper learning.
- Be mindful of how technologies collect your data and explore ways to protect your privacy online.
