We
see it everywhere. It's difficult to open a newspaper, listen to the
news on the TV or radio, or watch a documentary without being told,
"According to scientists
" or "Scientists have discovered
"
At times these "scientists" seem to take on the role of Delphic Oracle,
bestowing the news from on high.
But it wasn't
always so.
There was
a time, not all that long ago, when there were no "scientists,"
when science itself was being defined, and when men gathered, out
of interest, at a local pub to talk about what we might now regard
as "neat stuff." The time was 1645, the place London, and this casual
group of men went on to found what is now the world's oldest scientific
academy, The Royal Society.
Ideas about
how the natural world should be explored had been changing throughout
the Rennaissance, of course. But most educated people still looked
towards the classical authorities, particularly Aristotle, for the
road map to discovery. Aristotle's system was based on deductive
reasoning, you would look at a thing and deduce what led it to be
so. The problem with this, is that this kind of reasoning is dependent
on the experiences of the observer, which may or may not be focusing
on the relevant issues. Also, simple observation can lead to false
conclusions. For example, when looking at the circulation of blood,
people had noticed that after death the most blood could be found
in the liver, so they deduced that the liver must drive the circulation.
In the early
17th century, Francis
Bacon, the disgraced Lord Chancellor of England who turned to
philosophy in his retirement, outlined what he regarded as a method
for investigation which focused on gathering facts, observation
and analysis based on those facts. He was very cognizant of the
danger of imposing our own subjective ideas onto those facts. This
is what we all learned in High School as the "scientific method."
Two years
after Bacon's death in 1626, William
Harvey published his treatise on the circulation of blood and
caused a sensation. "I began to think," he said, "whether there
might not be a motion, as it were in a circle." Good thought. His
work, and his system of experimentation had a tremendous influence
on younger scientists, among them Robert
Boyle and Robert
Hooke, both of whom used Harvey's methods in their own work.
By
1645, at the close of the English Civil War, a small group of men
had begun to meet once a week in London. These initial enthusiasts
included John
Wilkins, Jonathan Godard, George
Ent, Dr.
Glisson, Dr.
Merret, Samuel Foster and John
Wallis. They were forbidden to discuss such subjective (and
explosive) matters as religion or politics, but were to concentrate
on the "natural world." Writing some years later, Wallis outlined
the subjects of discussion: "Our business was to discourse and consider
of Philosophical Enquiries, and such as related thereunto: as physic,
anatomy, geometry, astronomy, navigation, statics, magnetics, chemics,
mechanics, and natural experiments; with the state of these studies,
as then cultivated at home and abroad."
He goes on
to outline some specific areas of study: "We then discoursed of
the circulation of the blood, the valves in the veins, the venae
lactae, the lymphatic vessels, the Copernican hypothesis, the nature
of comets and new stars, the satellites of Jupiter, the oval shape
of Saturn, the spots in the sun, and its turning on its own axis,
the inequalities and selenography of the moon, the several phases
of Venus and Mercury, the improvement of telescopes, and grinding
of glasses for that purpose, the weight of air, the possibility
or impossibility of vacuities, and nature's abhorrence thereof,
the Torricellian Experiment in quicksilver, the descent of heavy
bodies, and the degree of acceleration therein; and in diverse other
things of like nature."
In the late
1640s some of the members moved to Oxford, where they started up
a new meeting group, now joined by architect Christopher
Wren and Robert Boyle. At first they met at William
Petty's home - he lodged with an apothecary which gave them
access to drugs for a variety of experiments. Then, after Petty's
move to Ireland, they began to meet at Boyle's home. The popularity
of the meetings and discussions attracted many new members, prompting
Boyle to christen the group, "the invisible college."
Following
the restoration of Charles II in 1660, they moved back to London
and it was there, at a meeting following one of Wren's lectures
at Gresham College, that they discussed "a designe of founding a
College for the Promoting of Physico-Mathematicall, Expermentall
Learning." This is regarded at the official founding of the Society,
and the members who were present at this meeting are considered
the Founding Fellows: Robert Boyle, Alexander Bruce, William
Viscount Brouncker, Sir
Robert Moray, Sir Paul Neile, John Wilkins, Jonathan Goddard,
William Petty, William Ball, Lawrence
Rooke, Christopher Hill and Abraham Hill.
Sir
Robert Moray trotted off to court and told Charles II of their proposed
society. The king was immediately smitten with the idea. Like others
of his age, Charles was interested in everything. He had a fascination
with clocks and watches, ending up with seven in his bedroom alone;
he longed for a lunar globe with the hills and canyons of its surface
molded and the whole thing in the proper shades of white; he pored
over new maps and had what others referred to as the "King's Tube,"
a telescope, installed in the Privy Garden. The king was more than
ready to grant his approval to the new Society.
Moray told
his colleagues the good news at their second meeting on the 5th
of December 1660. Two years later the king granted "The Royal Society"
its first charter, followed by another a year after that when he
granted them their arms. The motto chosen by the Society, Nullius
in Verbia (nothing by words), strove to summarize what had always
been their aim - to prove everything with facts, and not to rely
on anyone's word or opinion alone.
Following
the formation, the king at first wanted the Society to examine every
philosophical or mechanical invention before the patent was passed.
He eventually calmed down, but his enthusiasm was a product of his
time. And like Charles, the other Founding Fellows were interested
in everything. The idea of the scientist who specializes in one
branch of one science was alien to these men, for whom versatility
was everything. At the time, they were called virtuosos (another
word which has radically changed its meaning), which was applied
to people who were experts in a range of disciplines. Christopher
Wren, for example, was a Professor of Astronomy by the time he was
twenty-four, and admired throughout Europe for his mechanical invention.
He was over thirty before he decided to tackle architecture. Roger
North, a barrister, musician, author and architect also mastered
the theory of light. His brother, Francis, Lord Keeper of the Privy
Seal, was also an accomplished musician and devoted what remained
of his spare time to the Torricellian experiments.
The winner
in the virtuosity stakes would have to be Robert Hooke, however.
Little known now, partly as a result of arousing the enmity of Isaac
Newton, Hooke was highly regarded in his own time. His interests
covered physics, astronomy, chemistry, biology, geology, naval architecture
and architecture. He invented the universal joint, the iris diaphragm,
and an early prototype of the respirator; invented the anchor escapement
and the balance spring, which made more accurate clocks possible;
served as Chief Surveyor and helped rebuild London after the Great
Fire of 1666; worked out the correct theory of combustion; assisted
Robert Boyle in working out the physics of gases; worked out the
physics of elastic materials; invented or improved meteorological
instruments such as the barometer, anemometer, and hygrometer; and
that was probably all before breakfast. As an early paleontologist
he understood that fossils were not "sports of nature," but that
they had once been living things, and 250 years before Darwin he
realized that they documented changes among the organisms on the
planet, and that species have appeared and become extinct throughout
history. He also had a go at making a flying machine, going so far
as to make a model which "by the help of springs and wings, raised
itself in the air." He soon came to the realization that mankind
lacked the muscle power to make it work, so "I applied my mind to
contrive a way to make artificial muscles; divers designs whereof
I showed also at the same time to Dr. Wilkins, but was in many of
my trials frustrated of my expectations."
Gradually
the membership increased, and by the end of the century the Society's
members included Isaac
Newton, Nicolaus
Mercator, Edmund
Halley, William Croone, Christopher Merret, Denis
Papin, and Sir
Hans Sloane. Even diarist Samuel
Pepys became a member in 1665, noting in his diary what he saw
that day, "But it is a most acceptable thing to hear their discourses
and see their experiments; which was this day upon the nature of
fire, and how it goes out in a place where the ayre is not free,
and sooner out where the ayre is exhausted; which they showed by
an engine on purpose." After the experiments, Pepys and his new
colleagues repaired to the Crown tavern and had supper. Pepys remained
involved with the Society, eventually becoming its President. In
addition to their own experiments, The Society assigned someone
each year as "itinerant," whose job it was to travel the country
and report back on new discoveries. They sent experiments with anyone
traveling abroad who was willing, for example when Prince Rupert
was heading off to lead a fleet against the Dutch on the Guinea
coast, they asked him to spend his spare time sounding the depths
without a line, and requested that he bring back some water from
the bottom of the sea.
By the close
of Charles' reign, the Royal Society had become an institution.
From 1665 its work was recorded in "Philosophical Transactions,"
which became one of the earliest periodicals, and is still published
today. The venerable institution has provided the blueprint for
the foundation of similar organizations the world over, and science
has become the prism through which we all view our world.
But it was
those men in the 17th century who started it all, and whose joy
at discovery can still be felt even after 350 years. "The very remembrance
of these things," wrote Roger North in later years, "is delight,
and while I write methinks I play. All other employments that filled
my time go on account of work and business: these were all pleasure."
