Book summary “The Alchemy of Us”: summary

Introduction

You live in a world saturated with inventions that feel neutral, invisible, and entirely under your command. Yet every physical medium you adopt alters your daily habits, reshapes your sensory organs, and rewires your very biology without your conscious consent.

Humanity and physical materials engage in a reciprocal relationship where we shape matter, and that matter in turn rewrites our culture, habits, and biology.

Ainissa Ramirez explores this dynamic across seven technological revolutions that forged the modern mind. You will discover how inventions alter perception, emotion, and society.

• How did mechanical clocks fragment natural human sleep?
• In what ways did steel rails invent modern time zones?
• How did telegraph cables shrink language?
• Why did early photographic emulsions favor pale skin?
• How did electric light rewrite human biology?

1. Time and Interact

Standardized time and mechanical clocks reconfigured human sleep patterns and psychological perception.

Before widespread electronic synchronization, society relied on physical human couriers carrying highly accurate chronometers to distribute standard time to businesses and railways. Ruth Belville and her family operated a time-distribution service for 104 years. They carried a precise chronometer named Arnold from the Royal Observatory in Greenwich to clients across London, such as banks, pubs, and jewelers, to help them synchronize their clocks.

The Greenwich Time Lady

Ruth Belville, known as the Greenwich Time Lady, traveled weekly from Maidenhead to the Royal Observatory in Greenwich to check her watch Arnold against the master clock before making her rounds in London. The service charged clients an annual fee of £4 for this manual synchronization. Arnold was built in 1786 by John Arnold, and the journey from her cottage in Maidenhead to London covered 30 miles.

Segmented Sleep and Industrial Clocks

The Industrial Revolution and the adoption of clock time eradicated the historical human pattern of segmented sleep, replacing it with consolidated nighttime sleep. Before artificial lighting and factory clocks, Western humans routinely practiced first sleep and second sleep, waking for an hour or so in the middle of the night to read, pray, or chat. These intervals typically lasted about 3.5 hours each, far removed from the 7 hours of continuous sleep recommended by the National Sleep Foundation today.

Historical texts like Homer's Odyssey, Don Quixote, and thousands of nineteenth-century newspaper articles frequently referenced first sleep and second sleep. Today, 50 to 70 million Americans suffer from sleep disorders or sleep deprivation as industrial punctuality conflicts with older biological rhythms.

Quartz and Relative Time

Clockmakers struggled to build accurate timepieces because inferior, unevenly mixed metal springs caused watches to run erratically or snap. Benjamin Huntsman, an English clockmaker born in 1704, spent ten years failing hundreds of times in secret experiments before perfecting his crucible steelmaking process near Sheffield around 1740. By fully melting blister steel inside a special ceramic and graphite crucible for 5 hours, he thoroughly intermixed carbon and allowed lighter impurities to float to the top and be removed. This process required workmen to spend 8 to 10 hours stomping on the clay mixture with bare feet to knead it.

Warren Marrison developed the quartz clock at Bell Laboratories in 1927, which eventually enabled New Yorkers to dial ME7-1212 to learn the exact time. Marrison harnessed the piezoelectric properties of quartz crystals by cutting them into a doughnut shape that vibrated 100,000 times in one second when zapped with electricity.

Albert Einstein worked as a patent clerk in Bern, Switzerland, where real-world applications for synchronizing railway clocks inspired his theoretical breakthroughs. In 1905, while evaluating patent applications for clock synchronization methods, Einstein analyzed how light signals behave between stationary stations and moving trains. He later sketched out his idea for a clock system using light in 1913, demonstrating in his special theory of relativity that moving clocks run slower than stationary ones.

Louis Armstrong manipulated musical time through jazz performance, stretching and compressing notes to alter the listener's perception of temporal duration. In his 1928 recording Two Deuces, Louis Armstrong born in 1901 constantly played behind the beat before accelerating to catch up with his band. Early phonograph discs containing three-minute songs played at 78 rpm felt elongated due to information density.

Human brains do not measure time using uniform seconds, but rather estimate duration based on the density and novelty of stored memories. Neuroscientist David Eagleman conducted experiments using fast-running cheetah videos and blinking red dots to prove how environmental contexts alter human perception of time. When you experience novel or frightening events, your brain's amygdala records a massive amount of fine-grained detail into secondary memory, making the past event appear to have lasted longer upon recall.

2. Steel and Connections

The mass production of steel compressed time and space, enabling transcontinental railroads and commercialized holidays.

Steel achieves its unique combination of strength and malleability because its microscopic structure consists of alternating layers of hard, carbon-rich material and softer material. Steel is defined as iron combined with carbon. Unlike most metals where strength and malleability act like a seesaw, steel's layered microstructure unites both qualities, making it exceptionally versatile and durable for demanding applications like cannons and rails. You find that carbon thresholds matter immensely, as anything above 2 percent breaks like chalk, while ideal cannon steel needs 1 percent or less, and pig iron contains 4 percent.

Bessemer and Crucible Steel

Henry Bessemer invented a rapid and cheap method for mass-producing steel by blowing air through molten pig iron to violently oxidize and remove excess carbon. Inspired by the need for better steel for cannons during the Crimean War, Bessemer realized that introducing a massive blast of air from the bottom of a furnace would cause oxygen to react violently with carbon.

Bessemer's 1855 experiment erupted like Mount Vesuvius, generating deafening explosions, thick smoke, and bright flames that accidentally burned part of the building's roof.

American ironmaker William Kelly independently conceived an air-blowing method to reduce fuel costs in refining iron, leading to a fierce patent dispute with Henry Bessemer. Kelly operated the Eddyville Iron Works in Kentucky and observed that blowing air onto molten pig iron raised its temperature without additional fuel. Although he lacked Bessemer's understanding of carbon removal and metallurgy, the U.S. Patent Office granted him priority because he performed the technique first in 1847. William Kelly filed a case of interference on September 30, 1856, and ultimately secured U.S. patent #17,628 on June 23, 1857, despite going bankrupt after the Panic of 1857.

Producing high-quality steel required combining Bessemer's air-blast carbon reduction with additional chemical adjustments for manganese and phosphorus. Bessemer's initial process was prone to failure because it inadvertently removed manganese while failing to eliminate phosphorus. Successful mass production required merging patents for the air-blast method, Robert Mushet's manganese additive, and Sidney Thomas's phosphorus removal process.

Time-Space Compression

Railroads fundamentally compressed time and space, shrinking geographical distances and allowing towns, commerce, and populations to explode at unprecedented rates. Before railroads, travel relied on slow stagecoaches over grueling, weather-dependent routes, creating seasonal feasts and famines for merchants. Steel rails accelerated travel speeds by two to three times, replacing local subsistence economies with a connected national market that could reliably transport goods and people year-round.

Josiah Quincy described a punishing weeklong stagecoach journey from Boston to New York in old carriages with rope harnesses, contrasting sharply with the speed and ease introduced by the subsequent railway network. Total railroad tracks in the United States grew from 3,326 miles in 1840 to 30,600 miles by 1860, slightly exceeding the distance around the equator. Chicago's population jumped from 30,000 people in 1850 to triple that size by 1890.

Abraham Lincoln's funeral train served as a massive shared national ritual that temporarily united a geographically and politically fractured country in grief. In April 1865, Secretary of War Edwin Stanton organized a 1,600-mile funeral procession across fifteen railroad companies to transport Lincoln's body. Before standardized time zones and widespread newspapers, this train allowed millions to mourn in unison by bringing the president directly to them.

The Lincoln Special carried the president's remains through Washington, Baltimore, Harrisburg, Philadelphia, New York, Albany, Buffalo, Cleveland, Columbus, Indianapolis, and Chicago before reaching his final destination of Springfield, Illinois.

An Amalgamated Christmas

The modern American Christmas holiday was commercially manufactured and scaled through the infrastructure of steel railroads, which transported trees, cards, and gifts. Originally an unsavory or neglected holiday in early America, Christmas was transformed during the nineteenth century into a middle-class family tradition centered on gift-giving and retail consumption. Department store lobbying, presidential calendar shifts, and transcontinental train networks stitched together the modern holiday season.

The New York Times reported in 1893 on the fierce commercial market for Christmas trees hauled by trains from Maine to New York City, alongside an explosion in the popularity of Christmas cards and gift-giving.

3. Telegraphs and Convey

Before the invention of the telegraph, messages traveled by boat and horse like physical packages. A peace treaty ending the War of 1812 was signed in Ghent, Belgium, on Christmas Eve in 1814, but Major General Andrew Jackson fought and won the Battle of New Orleans on January 8, 1815, completely unaware that the war had already ended weeks prior.

Major General Andrew Jackson led an ill-prepared American force against the British at New Orleans, resulting in the needless deaths of soldiers because official word of the peace treaty did not reach Washington until mid-February and Jackson until March 6. This tragedy involved 4,000 ill-prepared American troops at New Orleans, 10,000 trained British soldiers at New Orleans, and 100 American dead in the battle.

Invention on the Sully

Samuel Morse conceived the electromagnetic telegraph during a transatlantic voyage in 1832 after hearing discussions about electricity and the instantaneous nature of electrical pulses through wires. While returning to America on the packet ship Sully after grieving his wife's death and failing to achieve artistic fame in Europe, Morse engaged in conversations with fellow passenger Dr. Charles T. Jackson about electromagnetism.

Lucretia Morse died in 1825. During a dinner conversation on the Sully, Dr. Charles T. Jackson described experiments where electricity traveled through loops of wire without loss of time, prompting Morse to sketch his ideas for an electromagnetic telegraph throughout the night.

Technical Refinements and Deployment

Early telegraph prototypes failed over distance until Morse incorporated scientific expertise regarding battery configuration and coil winding from academic colleagues. Morse's initial amateur setup failed to transmit signals over long lengths of wire because a single battery lacked sufficient pressure.

In January 1836, NYU chemistry professor Leonard Gale advised Morse to link multiple batteries in a row and to wrap dozens or hundreds of turns of wire around the horseshoe magnet, drawing on an 1831 scientific paper by physicist John Henry. Securing government funding for the first telegraph line culminated in a successful demonstration transmitting the first official message between Washington, DC, and Baltimore. Morse and his collaborator Alfred Vail constructed an overhead wire system connecting Washington, DC, and Baltimore after securing a $30,000 congressional appropriation.

Annie Ellsworth selected a Bible passage from Numbers 23:23, which Morse transmitted via dots and dashes from the Supreme Court office in Washington to Vail in Baltimore, resulting in the famous message 'What Hath God Wrought' during the 1844 official demonstration across the 40 miles between Washington and Baltimore.

Brevity and Modern Consequences

Technical bandwidth limits and economic pricing structures of early telegraphs forced a profound condensation of language that transformed American prose and journalistic style.

Because early telegraph wires could only transmit one message at a time and companies charged flat rates for the first ten words with extra fees for additional words, senders learned to drop prepositions and superfluous terms. By 1903, half of all telegram transmissions were ten words or fewer. Ernest Hemingway was born in 1899.

Ernest Hemingway learned concise prose rules as a cub reporter at the Kansas City Star, applying style sheet directives that mirrored the brevity imposed by telegraph technology.

You can observe these classic rules in editorial guidance:

• Use short sentences.
• Use short first paragraphs.
• Use vigorous English.
• Be positive, not negative.
• Eliminate every superfluous word.
• Avoid the use of adjectives.
• Watch out for trite phrases.

When President James A. Garfield was shot by Charles J. Guiteau on July 2, 1881, the telegraph and newly expanded news services like the Associated Press transmitted regular medical bulletins to chalkboards and newspapers nationwide. Garfield served as president for 200 days and battled infection for 80 days before dying.

Professor Naomi S. Baron noted that online communication is significantly undermining social interactions because people build up anxieties if they do not receive immediate digital responses, ultimately making us unsocial beings.

4. Photography and Capture

Motion-capture and flexible roll film democratized visual recording but embedded systemic racial biases into technology.

In the 1870s, photographic plates required long exposure times, rendering moving objects invisible or blurry. Leland Stanford wanted to prove that a running horse has a moment of unsupported transit with all four feet off the ground.

Leland Stanford bet $25,000 that a running horse experiences unsupported transit, leading him to hire Eadweard Muybridge to photograph his famous horse, Occident, and later perform experiments at the Palo Alto Stock Farm. Muybridge initially used wet glass plates and a guillotine-like shutter, then upgraded to an electric bell mechanism. By stringing a series of threads across a track connected to multiple cameras, the horse snapped its own pictures in rapid succession, proving Stanford's theory.

Reverend Hannibal Goodwin invented transparent, flexible roll film after becoming frustrated with fragile glass slides breaking during Sunday school lessons. While teaching Bible stories using a magic lantern, Goodwin found that glass slides frequently cracked in the hands of children. Operating from his attic chemistry workshop, he spent a decade experimenting to create a thin, flexible plastic photographic film.

Hannibal Goodwin, an Episcopalian pastor in Newark, New Jersey, spent years in his attic workshop creating flexible film and later fought a monumental legal battle against Eastman Kodak. He dissolved nitrocellulose in liquid nitrobenzole and alcohol, pouring it onto glass to dry into a thin layer. He filed a patent for this photographic pellicle in 1887, initiating a multi-decade legal and patent battle against George Eastman's company.

Bias in Technology

Early color photographic film and standard color balance cards were optimized for white skin, rendering darker skin tones underexposed and distorted. When color photography became widespread, color scientists used standardized calibration tools known as Shirley cards, featuring a white woman with light skin and blue eyes.

In the 1960s, African American mothers noticed that school class photos failed to capture black children equally compared to white children due to the inherent bias in color film formulations. Because the chemistry and exposure were calibrated to match this standard, darker skin tones appeared burnt, muddy, or entirely underexposed, turning black children in integrated school photos into indistinct ink blots.

Commercial pressures from industries requiring accurate dark hue representation ultimately forced film manufacturers to reformulate color film. Furniture makers and chocolate manufacturers protested against Kodak's films for failing to display dark browns and wood grains clearly, prompting Kodak to create new film formulations. While complaints from black mothers regarding class photos were largely ignored by Kodak, protests from furniture and chocolate manufacturers changed corporate behavior.

Activism and Human Rights

Frederick Douglass utilized photography as a democratic medium to counter negative racial stereotypes by distributing dignified portraits of himself. Frederick Douglass became the most photographed human being of the nineteenth century, surpassing Lincoln and Grant, using his portraits to combat slavery and negative media depictions. Recognizing that early daguerreotype photography provided an equal opportunity to reproduce likenesses accurately through simple chemistry, Douglass sat for photographs more than anyone else of his era.

Employees Caroline Hunter and Ken Williams launched the Polaroid Revolutionary Workers Movement to protest the company's complicity in South African apartheid. Caroline Hunter and Ken Williams discovered an identification card mock-up on a bulletin board at Polaroid in 1970, which led them to found the Polaroid Revolutionary Workers Movement and force the company's eventual withdrawal seven years later. Upon discovering that Polaroid's ID-2 instant photographic system was used to produce passbooks that monitored and restricted the movement of millions of black South Africans, employees organized grassroots protests.

Polaroid added a Face Brightener button to its instant cameras to compensate for the fact that its film poorly registered darker skin tones. Photographers Adam Broomberg and Oliver Chanarin analyzed Polaroid's Face Brightener button, noting that it boosts the flash by 42 percent to match the extra light absorption of dark skin. Because Polaroid designed its instant photography products primarily for white customers, photos taken of individuals with dark skin lacked discernible details.

5. Light and See

Thomas Edison was inspired to pursue incandescent electric lighting after witnessing William Wallace's powerful carbon arc lamp during a visit in 1878. On September 8, 1878, Edison visited William Wallace's private laboratory on Liberty Street in Ansonia, Connecticut, where he saw an arc lamp powered by the telemachon generator flood the room like a searchlight.

Edison succeeded in creating a long-lasting incandescent bulb only after abandoning platinum and returning to carbon filaments housed within a superior vacuum.

In late October 1879, Edison's laboratory tested improved carbon filament lamps in a vacuum, with one bulb glowing successfully for forty hours.

Artificial light at night disrupts the human circadian rhythm by suppressing melatonin production and keeping the body in a constant daytime growth mode. Professor Thomas Wehr noted that modern humans are taller and experience higher growth hormone levels and altered seasonal conception rates due to constant exposure to artificial light.

To maintain health under modern lighting conditions, you must adopt a daily lighting routine characterized by bright mornings and dim, redder evenings.

• Start the day by taking a walk outdoors to get exercise and a bolus of bright blue light.
• Dim indoor lights way down starting at dusk.
• Use a light source that is incandescent in the evening.
• Reduce the blue light coming from computer monitors, television displays, and cellphone screens at night.
• Stay in the dark if you wake up in the middle of the night to make it easier to get back to sleep.

Artificial lights disrupt animal behavior, impairing the mating communication of fireflies and causing fatal disorientation in migrating birds and sea turtles. Ecologist Travis Longcore noted that approximately 6.8 million birds die annually in the US and Canada from flying around illuminated communication towers.

6. Data and Share

The evolution from analog phonograph grooves to digital magnetic hard disks transformed sound and information into storable commodities.

The Phonograph and Democratized Music

Thomas Edison invented the phonograph in 1877 by combining telegraph recording techniques with telephone diaphragm vibrations, creating the first machine to capture and play back sound. On December 6, 1877, machinist John Kruesi completed the cylinder phonograph, and Edison famously recited the nursery rhyme Mary Had a Little Lamb into the mouthpiece.

The phonograph changed the shape of data and democratized music by shifting performances from large concert halls into private homes, though early devices favored louder instruments. Record sales soared to twenty-six million by 1906 and one hundred million by 1927.

Cassettes and Binary Code

Magnetic cassette tapes allowed users to copy sounds and curate personal playlists, giving rise to the mixtape as a sonic incarnation of individual identity. Over 130 million cassette tapes were sold in 1977, fueling the culture of sharing and collecting personalized music.

The transition from analog grooves to digital magnetic bits introduced the binary language of ones and zeros, enabling computers to process information without human intervention. In 1854, mathematician George Boole established that simple statements of logic could be represented with true and false values.

IBM faced a storage crisis due to the billions of paper punchcards generated by census data, prompting the establishment of a West Coast research lab to find a compact storage solution. By 1952, producing sixteen billion punchcards annually became unsustainable for sorting and real-time access.

The Invention of the Hard Disk

IBM engineers in San Jose invented the hard disk by proposing a stack of spinning magnetic disks inspired by record players and jukeboxes.

Jake Hagopian successfully coated pizza-sized aluminum disks using a drill and a Dixie cup of paint, later straining the mixture through his wife's silk stockings to remove lumps.

NASA's Voyager space probes carried a twelve-inch gold-coated copper disc containing sounds, images, and music from Earth designed to outlive the planet itself. In 1977, twin Voyager spacecrafts were launched using a rare planetary alignment every 176 years to slingshot across the solar system using gravity.

Modern digital streaming platforms and websites collect continuous behavioral data about users, turning humans into the final step in the evolution of data collection. Websites like Napster, YouTube, and various streaming services pioneered the ubiquity of digital media while simultaneously harvesting granular user metrics.

7. Glass and Discover

Humanity relies on transparent materials to explore both the microscopic world and the vast cosmos. A rigid structure can hide crucial secrets unless you look through clear panes. Traditional glassmaking relied on stagnant recipes rather than technical know-how.

Scientific glass formulations like borosilicate glass revolutionized optics, laboratory instruments, and domestic baking.

Schott, Abbe, and Optical Glass

Physicist Ernest Abbe identified flaws like bubbles and color separation in microscope lenses. He published a report calling for scientifically engineered glass to improve optical instruments. Otto Schott used the periodic table like a restaurant menu to test different chemical additives. In 1879, Schott wrote to Professor Ernest Abbe offering to supply various experimental glass types. This led to a fruitful collaboration in Jena, Germany, and the creation of Schott & Associates Glass Technology Laboratory in 1884. Schott discovered that adding boron created borosilicate glass with uniform and predictable properties.

Nonex and Pyrex Bakeware

American glassmaker Corning sought an alternative to German Jena glass. By hiring chemists and applying the scientific method, they created Nonex. Corning Glass Works, originally from Brooklyn and relocated to Corning, New York, in 1868 to utilize canal transport, successfully supplied hardy Nonex glass to the railroad industry. Train signal lights frequently cracked because interior heat from arc lights caused the glass to expand while rain or snow rapidly cooled the outside. Nonex resisted these thermal shocks and survived target practice from boys with BB guns.

In 1913, J.T. Littleton brought home-baked goods and battery-jar casserole dishes home to his wife Bessie in Corning, New York, leading to the creation of the Pyrex brand in 1915. You can achieve uniform results with this material because glass transmits invisible heat rays like the sun. You can use this technique with everyday ingredients:

• Mix ingredients for a white cake using sugar, eggs, flour, butter, milk, vanilla, and baking powder
• Pour the batter into a smooth glass baking dish
• Bake in the oven to produce an evenly browned cake that easily removes from the pan

The Discovery of the Electron

Scientific glassware also enabled breakthroughs in physics and medicine. Alexander Fleming left stacks of unwashed petri dishes on his laboratory bench. In September 1928, Fleming returned to his St. Mary's Hospital laboratory in London after a six-week vacation, discovered mold inhibiting bacteria in a neglected petri dish, and subsequently identified penicillin. In the summer of 1897, Ebeneezer Everett completed the glass cathode-ray obstacle course at Cambridge University, enabling J.J. Thomson to calculate the properties of the electron. Thomson observed that cathode-ray tubes contained negatively charged particles smaller than an atom.
