How Wonderfully We Stand Upon This World
By Dr. Alan Hirshfeld
Step through the front door of
George Riebau’s bookbindery
at 2 Blandford Street near Manchester Square in London and
feel the present dissolve into centuries-past. The pungent
aroma of leather, glue, and varnish invades the nostrils.
A murmurous drumbeat – the binder’s mallet tamping
gathered pages – sounds an insistent rhythm: work,
work, work. Books are everywhere, on shelves, on tables,
even wedged into the cubby-like window frames, where they
eclipse the light that struggles to enter. In this dim paper-and-leather
universe of long ago, French émigré George
Riebau and his three apprentices stand at their posts, plying
the bookbinder’s craft. Before them lie the accoutrements
of their trade: needles, thread, Jaconette cloth, engraving
tools, standing press, cutting boards. The room buzzes with
conversation, for Riebau is a genial man who likes to keep
his workers and his customers happy. Yet for all the chatter,
the binding and selling of books appear to be the sole order
of business here. In short, George Riebau’s modest
establishment is the last place one would conceive as an
incubator for an aspiring scientist. Especially in 1812 England.
But move beyond the benches to
the fireplace that keeps the workers’ fingers supple through the frigid London
winters. There on the mantelpiece, arrayed in no particular
order, is a curious assortment of devices that bear no connection
to the binding of books: Voltaic piles – batteries,
in today’s parlance; copper and zinc electrodes; coils
of wire; bottled acids; glass cylinders for generating and
storing electricity. Nearby, meticulous pencil sketches of
electrical machines. And alongside these, jottings about
electrical phenomena. Here is the after-hours “laboratory” of
young Michael Faraday, one of George Riebau’s apprentices,
who is at present probably counting the minutes until he
can set aside his tools and resume his homespun experiments.
Faraday’s teachers, such as they are, do not wear silken
robes or roam ivy-covered buildings; they speak to Faraday
silently from the printed pages that pass through his hands
on the way to more advantaged customers. To Faraday, Riebau’s
shop is truly library, classroom, and laboratory. The mantelpiece
curios are manifestations of a dream by a young man whose
ambitions press ever more despairingly against the harsh
realities of British society. This is an age when the term “upward
mobility” holds no practical meaning for the mass of
humanity – when, for the most part, scientists are
born, not made.
In a few short months, Michael
Faraday’s apprenticeship
will end and, for his family’s sake, he must dutifully
take up the career for which he trained: bookbinding. And
therein lies the source of the searing realization that his
life might be spent in the mindless packaging of countless
words on countless subjects, and not one of his own devising.
For Faraday longs to uncover nature’s secrets, not
as a hobbyist in some dusty shop corner, but as a professional
man of science in a real laboratory. Only then might he fulfill
his deep-seated goal: to discern God’s invisible qualities
through the very design of the world. That this modest apprentice
would surmount the many obstacles in his path and lay the
foundations of our modern technological society is the true
essence of the power of purpose.
Born in a London slum in 1791,
Michael Faraday came to George Riebau’s bookbindery in 1805. The shop proved a fertile
environment for the inquisitive, but virtually unschooled,
Faraday. Books came in, books went out, a steady stream of
treacle and treasure that Faraday sampled haphazardly in
his off-hours. This week’s “lesson” might
be Arabian Nights, next week’s a collection of Hogarth
illustrations, and after that, Fanny Burney’s edgy
take on English society, Evelina. But it was books on science
that excited him most.
At the dawn of the 19th century,
science and its institutions were in flux, spurred as much
by new discoveries as by the
growing belief that scientific research might enhance a nation’s
agricultural and industrial development. The fundamental
building blocks of matter – atoms – were as yet
unknown. Electricity, magnetism, heat, and light were variously “explained,” none
convincingly. Through careful measurement, the mathematical
character of nature’s forces could be determined, but
their underlying mechanisms, interrelationships, and means
of conveyance through space were subject to dispute. Faraday
plunged headlong into this melange of ideas, trying with
his meager knowledge to sort out fact from fancy. His scientific
musings tumbled joyfully, almost uncontrollably, in his head.
Riebau described his young charge as perpetually scouring
the countryside, “searching for some Mineral or Vegitable
curiosity ... his mind ever engaged.” All around was
God’s handiwork, in plain sight, yet inextricably bound
up in mystery. Faraday saw no higher purpose than to study,
comprehend, and share with others the subtle plan of nature.
Inspired by his literalist reading
of the New Testament, Faraday eschewed pride and wealth
in favor of piety, humility,
and community within his small Protestant congregation. Much
of his overt serenity in later life owed itself to the affirmative
aspects of his religion. “He drinks from a fount on
Sunday which refreshes his soul for a week,” noted
a friend. Faraday’s spiritual framework informed his
science without compromising his objective consideration
of facts. He believed that God’s signature would appear
in a fundamental unity of the universe, a philosophy that
shaped his scientific outlook. And he took human fallibility
as a given, so never staked his ego on the correctness or
acceptance of his ideas. He was a scientific pilgrim, inching
his way toward the heart of a complex universe. Whether his
chosen path proved mistaken was of little consequence; there
was always another path. The joy was in the journey.
Although the young Faraday might have fancied himself a
proto-scientist, he was too grounded not to see who stared
back at him from the mirror: a rough-edged, ill-educated
son of a blacksmith. Characterizing his own language as “that
of the most illiterate,” he took elocution lessons
two hours every week for seven years. He ordered his friends
to mercilessly correct his speech, spelling, grammar. For
ready reference, he carried in his pocket the popular self-help
volume Improvement of the Mind. He attended evening lectures
on science and began a commonplace book, whose pages he
filled with miscellanea about the natural world.
When the new edition of the Encyclopedia
Britannica arrived in the shop, Faraday devoured the 127-page
entry on electricity.
He followed up with Jane Marcet’s Conversations on
Chemistry, which detailed the electrochemical discoveries
of England’s celebrated scientist, Humphry Davy. Faraday
was the consummate skeptic: he trusted his eyes and senses
to be the sole arbiters of what was true and what was not.
In Riebau’s back room, he validated Davy’s experimental
claims as best he could. “I was a very lively, imaginative
person, and could believe in the ‘Arabian Nights’ as
easily as in the ‘Encyclopedia’; but facts were
important to me and saved me.” Faraday had further
reason to admire Davy: the now-famous chemist had risen from
humble circumstances like his own; Davy had become what Faraday
longed to be.
In early 1812, a customer learned
of Faraday’s scientific
interests and invited him to hear Humphry Davy speak at London’s
Royal Institution. Davy’s evening lectures had become
social events for the well-heeled, turning normally sedate
Albemarle Street into a frenzy of carriages and pedestrians.
Faraday’s pulse was surely pounding as he ascended
the broad, stone staircase to the Royal Institution’s
auditorium. Hearing Davy describe his recent work only strengthened
his resolve. “The desire to be engaged in scientific
occupation, even though of the lowest kind, induced me, whilst
an apprentice, to write, in my ignorance of the world and
simplicity of my mind, to Joseph Banks, then President of
the Royal Society.” England’s venerable Royal
Society, established in 1645, was England’s premier
scientific organization and boasted in its lineage the likes
of Christopher Wren, Isaac Newton, and Edmund Halley. Faraday
went to the Society’s offices only to be told that
his letter “required no answer”; in the eyes
of the scientific establishment, Michael Faraday did not
exist. Undeterred, he wrote and illustrated a 386-page synopsis
of Davy’s theory of acids and sent the leather-bound
volume to Davy, along with a letter pleading his case. This
time there was a reply, delivered to his door by a footman
in a grand carriage. On March 1, 1813, Faraday took up his
new post as Humphry Davy’s laboratory assistant: salary
one guinea per week; lodging in the attic with fuel and candles;
and, most critically, access to the Royal Institution’s
apparatus.
Faraday reveled in his day to day
interactions with Davy, who tutored him in all manner of
laboratory techniques. In
October 1813, the pair embarked on a prolonged tour of Europe’s
scientific facilities. To Faraday, who had never strayed
more than three miles beyond London, the trip was a living
tutorial in science, geography, art, history, politics, and
manners. Imagine the impact of the snow-capped Alps on a
young man who had earlier marveled at the “mountains” of
Devonshire. Every day presented a sight or event worthy of
entry into his journal: glimpsing Napoleon in a procession;
describing the anatomy of French pigs; inspecting Galileo’s
celebrated telescope; incinerating a diamond in Florence;
climbing the slopes of Vesuvius. By the time he returned
a year and a half later, Faraday could maneuver with confidence
through the social thicket as well as the laboratory. He
worked incessantly, both for Davy and for others in need
of his analytical skills. In 1816, Faraday published his
first scientific paper, on the chemical properties of caustic
lime. Other papers followed in quick succession. Faraday
delivered his own series of lectures at the City Philosophical
Society, and was increasingly sought out as a technical advisor.
To Davy’s consternation, the standing of his acolyte
from the slums began to rival his own.
In 1820 came news of a remarkable discovery: Danish physicist
Hans Christian Oersted had found that an electrical current
flowing in a wire deflects a magnetic compass needle: electricity
generates magnetism. Repeating Oersted’s experiment,
Faraday realized that such electrically induced magnetism
might be harnessed for rotary motion. In 1821, he assembled
the first electric motor, in which a suspended, electrified
wire circled the pole of a magnet. Announcement of the
curious contraption brought Faraday immediate notoriety – and
near ruin. Rumors circulated – rumors, Faraday learned,
stoked by Davy – that he had stolen his idea from
unpublished work by William Hyde Wollaston, one of England’s
foremost scientists. Only after two agonizing years, and
repeated entreaties from Faraday, did Wollaston grudgingly
break his silence and speak in Faraday’s defense:
the discovery of the electric motor was Faraday’s
own. Davy subsequently opposed his protege’s nomination
to the Royal Society, to no effect; Faraday was elected – the
lone dissenting vote presumably Davy’s own. Even
so, Faraday never spoke ill of his mentor; his spiritual
imperative was to reveal the workings of nature, not the
shortcomings of man. To do so would have merely detracted
from the nobility of his cause.
Faraday’s most far reaching contributions came in
1831, when he succeeded in generating electricity from
magnetism. First, he showed that the magnetism of an electrified
wire coil creates an electric current in an adjacent coil;
here lay the foundation of the modern electrical transformer.
He found, too, that he could induce spurts of current in
a coil by simply thrusting a magnet into the coil’s
interior. And by spinning a copper disk between the poles
of a magnet, Faraday produced a steady stream of electricity – the
world’s first dynamo. Here was the generation of
electrical power by machine. The societal implications
were enormous.
Pondering next the interconnectedness
of electricity and magnetism, Faraday entered the laboratory
of the mind and
modeled electrical and magnetic forces in a completely new
way: as tensioned lines of force surrounding electric charges,
magnets, circuits– invisible motive tentacles that
impel material objects that stray among them. In Faraday’s
conception, force arises, not when some impulse shoots instantaneously
from a seat of power to a remote object, but when the object
encounters the “force field” that surrounds every
seat of power. In keeping with his unified view of nature,
he wondered whether light might be a related phenomenon,
perhaps a vibratory disturbance of intertwined electrical
and magnetic fields. He envisioned waves of light – ripples
of “electromagnetic” energy – fanning out
through the field like waves on a pond.
Here Faraday’s quest to elucidate reality encountered
its severest challenges: his own intellectual limitations
and the prejudices of his contemporaries. Faraday’s
particular gift was to make visible in the laboratory that
which had been invisible, to magnify nature’s subtle
effects to the point of sensibility. He was a powerful thinker
whose speculations (by choice) were anchored solely in what
was rendered plain by experiment. Only now he had entered
a realm of study in which experimental verification was difficult,
if not impossible – the realm of the mathematician,
who solves equations to find plausible explanations of physical
phenomena. And Faraday, facile as he was in the laboratory,
was a grade-school mathematician. At a time when mathematics
was fast becoming the key analytical tool of theoretical
physics, Faraday put forth his revolutionary ideas in the
only way he could, through the skilled use of intuition,
logic, and language.
So taxing was his mental effort
to explain nature’s
underlying architecture (heaped high atop other work) that
by late 1839 Faraday was felled by nervous exhaustion, and
for five years remained silent on the subjects of electricity
and magnetism. He returned with an exquisite experiment proving
that light can be altered by magnetism; as he had predicted,
light possesses a magnetic character. Then came a speculative
paper summarizing his thoughts on “ray vibrations,” a
remarkably prescient forerunner of the modern electromagnetic
theory of light. The scientific establishment viewed these “ramblings” with
bemusement, if not scorn, for the new language of science
was mathematical. Faraday’s response: “Nothing
is too wonderful to be true, if it be consistent with the
laws of nature.” It would not be until the 1870s that
the gifted mathematician James Clerk Maxwell fully translated
Faraday’s complex ideas into the hard dialect of equations.
Only then did scientists concede the essential correctness
of Faraday’s views on force and light, which Einstein
characterized as the “greatest alteration … in
our conception of the structure of reality since the foundation
of theoretical physics by Newton.”
Beyond the motor, generator, and
other electromagnetic advances, the list of Faraday’s
contributions to humanity runs long, touching areas as
diverse as chemistry, geology, metallurgy,
optics, cryogenics, and education. He sought no personal
gain from his discoveries and routinely refused honors and
lucrative consultantships as immaterial to his committed
purpose.
For nearly forty years, Faraday
invited the public to the Royal Institution to share his
enduring sense of wonder: “Let
us now consider, for a little while, how wonderfully we stand
upon this world.” Complete with sparks, flames, and
all manner of devices, Faraday’s Friday Evening Discourses
and annual Christmas lectures for children established him
as England’s scientific ambassador to its citizenry.
One attendee recalled how Faraday’s “enthusiasm
sometimes carried him to the point of ecstasy when he expatiated
on the beauty of nature.” Transcriptions of his children’s
lectures reveal his gentle, avuncular style, and also how
addressing young audiences provided a source of renewal: “I
will return to second childhood, and become as it were, young
again among the young.”
There is a serenity in knowing
that nature is explicable and beckons generation after
generation to know it better.
Michael Faraday sought to understand the natural world on
behalf of us all, in the belief that the revealed knowledge
would nourish the collective soul of humanity. He was one
of those rare scientists in the mold of Galileo, Newton and
Einstein, free of blinding preconceptions about nature and
thus endowed with a vision denied his contemporaries. Faraday’s
legacy is nothing less than our own technological society.
Through his unrelenting power of purpose, the onetime binder
of books appropriately invited nature to pen another chapter
in the story that is our universe.
