The scientific revolution
The scientific
revolution is a concept used by historians to describe the emergence
of modern science during the early modern
period, when developments
in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed the views of society about
nature. While its dates are debated, the publication in 1543 of Nicolaus
Copernicus's De revolutionibus orbium coelestium (On the Revolutions of the Heavenly
Spheres) is often cited as marking the beginning of the scientific
revolution.The beginning of the scientific revolution, the Scientific
Renaissance, was focused on the recovery of the knowledge of the ancients;
this is generally considered to have ended in 1632 with publication of Galileo's Dialogue Concerning the Two Chief World Systems.[8] The completion of the scientific revolution is
attributed to the "grand synthesis" of Isaac Newton's 1687 Principia, that formulated the laws of motion and universal
gravitation, and completed the
synthesis of a new cosmology.
Great advances in science
have been termed "revolutions" since the 18th century. In 1747, Clairaut wrote that "Newton was said in his own lifetime to have created a revolution".[10] The word was also used in the preface to Lavoisier's 1789 work announcing the discovery of oxygen. "Few
revolutions in science have immediately excited so much general notice as the
introduction of the theory of oxygen ... Lavoisier saw his theory accepted by
all the most eminent men of his time, and established over a great part of
Europe within a few years from its first promulgation.
"A new view of nature
emerged, replacing the Greek view that had dominated science for almost 2,000
years. Science became an autonomous discipline, distinct from both philosophy
and technology and came to be regarded as having utilitarian goals. The
scientific revolution is traditionally assumed to start with the Copernican
Revolution (initiated in 1543)
and to be complete in the "grand synthesis" of Isaac Newton's 1687 Principia. Much of the change of attitude came from Francis Baconwhose "confident and emphatic announcement" in the
modern progress of science inspired the creation of scientific societies such
as the Royal Society, and Galileo who championed Copernicus and developed the science of motion.
Rapid accumulation of
knowledge, which has characterized the development of science since the 17th
century, had never occurred before that time. The new kind of scientific
activity emerged only in a few countries of Western Europe, and it was
restricted to that small area for about two hundred years.
It is also true that many
of the important figures of the scientific revolution shared in the
general Renaissance respect for ancient learning and cited
ancient pedigrees for their innovations. Nicolaus
Copernicus (1473–1543),[25] Kepler (1571–1630),[26] Newton (1642–1727),[27] and Galileo Galilei (1564–1642)[1][2][3][28] all traced different ancient and medieval ancestries
for the heliocentric system. In the Axioms Scholium of his Principia, Newton said its
axiomatic three laws of
motion were already
accepted by mathematicians such as Huygens (1629–1695), Wallace, Wren and others.
While preparing a revised edition of his Principia, Newton
attributed his law of gravity and
his first law of
motion to a range of
historical figures.
By the end of the
scientific revolution the qualitative world of book-reading philosophers had
been changed into a mechanical, mathematical world to be known through experimental
research. Though it is certainly not true that Newtonian science was like modern science in all respects,
it conceptually resembled ours in many ways. Many of the hallmarks of modern science, especially with regard to its
institutionalization and professionalization, did not become standard until the
mid-19th century.
The term British empiricism
came into use to describe philosophical differences perceived between two of
its founders Francis Bacon, described as empiricist, and René Descartes, who was described as a rationalist. Thomas Hobbes, George Berkeley, and David Hume were the philosophy's primary exponents, who developed
a sophisticated empirical tradition as the basis of human knowledge.
Bacon proposed a great
reformation of all process of knowledge for the advancement of learning divine
and human, which he called Instauratio Magna (The Great
Instauration). For Bacon, this reformation would lead to a great advancement in
science and a progeny of new inventions that would relieve mankind's miseries
and needs. Bacon considered that it is of greatest importance to science not to
keep doing intellectual discussions or seeking merely contemplative aims, but
that it should work for the bettering of mankind's life by bringing forth new
inventions, having even stated that "inventions are also, as it were, new
creations and imitations of divine works".[35][page needed] He explored the
far-reaching and world-changing character of inventions, such as the printing press, gunpowder and the compass.
Galileo
Galilei has been called the
"father of modern observational
astronomy",[42] the "father of modern physics",[43][44] the "father of science",[44][45] and "the Father of Modern Science".[46] His original contributions to the science of motion
were made through an innovative combination of experiment and mathematics. his work marked another step towards the eventual separation of
science from both philosophy and religion; a major development in
human thought. He was often willing to change his views in accordance with
observation. In order to perform his experiments, Galileo had to set up
standards of length and time, so that measurements made on different days and
in different laboratories could be compared in a reproducible fashion. This
provided a reliable foundation on which to confirm mathematical laws
using inductive
reasoning.
Galileo showed a
remarkably modern appreciation for the proper relationship between mathematics,
theoretical physics, and experimental physics. He understood the parabola, both in terms of conic sections and in terms of the ordinate (y) varying as the square of the abscissa (x). Galilei further asserted that the parabola was the
theoretically ideal trajectory of a uniformly accelerated projectile in the absence
of friction and other disturbances. He conceded that there are limits to the
validity of this theory, noting on theoretical grounds that a projectile
trajectory of a size comparable to that of the Earth could
not possibly be a parabola,[50] but he nevertheless maintained that for distances up to
the range of the artillery of his day, the deviation of a projectile's
trajectory from a parabola would be only very slight.
Gravity, interpreted as an innate attraction
between every pair of particles of matter, was an occult quality in the same
sense as the scholastics' "tendency to fall" had been.... By the mid
eighteenth century that interpretation had been almost universally accepted,
and the result was a genuine reversion (which is not the same as a
retrogression) to a scholastic standard. Innate attractions and repulsions
joined size, shape, position and motion as physically irreducible primary
properties of matter.
The French established
the Academy of
Sciences in 1666. In contrast
to the private origins of its British counterpart, the Academy was founded as a
government body by Jean-Baptiste
Colbert. Its rules were set down
in 1699 by King Louis XIV, when it received the name of 'Royal Academy
of Sciences' and was installed in the Louvre in Paris.
Practical attempts to
improve the refining of ores and their extraction to smelt metals was an
important source of information for early chemists in the 16th century, among
them Georg Agricola (1494–1555), who published his great
work De re
metallica in 1556.[82] His work describes the highly developed and complex
processes of mining metal ores, metal extraction and metallurgy of the time.
His approach removed the mysticism associated with the subject, creating the
practical base upon which others could build.
English chemist Robert Boyle (1627–1691) is considered to have refined the modern
scientific method for alchemy and to have separated chemistry further from
alchemy.[84] Although his research clearly has its roots in
the alchemical tradition, Boyle is largely regarded today as the first
modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method. Although Boyle was not the original discover,
he is best known for Boyle's law, which he presented in 1662:[85] the law describes the inversely proportional relationship
between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system. Importantly, he advocated a rigorous approach to scientific
experiment: he believed all theories must be tested experimentally before being
regarded as true. The work contains some of the earliest modern ideas of atoms, molecules, and chemical reaction, and marks the beginning of the history of
modern chemistry. Robert Boyle also worked frequently at the new science of
electricity, and added several substances to Gilbert's list of electrics. He
left a detailed account of his researches under the title of Experiments
on the Origin of Electricity.[92] Boyle, in 1675, stated that electric attraction and
repulsion can act across a vacuum. One of his important discoveries was that
electrified bodies in a vacuum would attract light substances, this indicating
that the electrical effect did not depend upon the air as a medium. He also
added resin to the then known list of electrics.
John Napier introduced logarithms as a powerful mathematical tool. With the help of the
prominent mathematician Henry
Briggstheir logarithmic tables
embodied a computational advance that made calculations by hand much quicker.[97] His Napier's bones used a set of numbered rods as a
multiplication tool using the system of lattice
multiplication. The way was
opened to later scientific advances, particularly in astronomy and dynamics.
Abraham Darby
I (1678–1717) was the first, and most
famous, of three generations of the Darby family who played an important role
in the Industrial
Revolution. He developed a method of
producing high-grade iron in a blast furnace fueled by coke rather than charcoal. This was a major step forward in the production of iron as a raw
material for the Industrial Revolution.
Evangelista
Torricelli (1607–1647) was best
known for his invention of the mercury barometer. The motivation for the invention was to improve on the
suction pumps that were used to raise water out of the mines. Torricelli constructed a sealed tube filled with mercury, set
vertically into a basin of the same substance. The column of mercury fell
downwards, leaving a Torricellian vacuum above.
