Technology
before the Industrial Revolution: Hobsbawm intro-1
Why look at the more distant past?
when we have more distance we can see change and we can
see patterns more clearly
an older friend said (on Facebook): "I do remember
separate schools and bathrooms and water fountains and not
being allowed into each others homes. I remember my father
paying poll taxes so black friends could vote. I remember
thinking this was the way life was. I remember realizing it
didn't have to be that way and consciously changing my mind
set."
to see very different patterns, realize that what we see
today is the result of history and choices, it isn't just
human nature
First the introduction to Hobsbawm: What
do historians do?
What is this book trying to do?
persuade the reader, not just state facts
Hobsbawm says this book does not wholly represent the
consensus of experts--this is to some extent one side of an
argument, not a textbook trying to present all sides fairly
explain why the British Industrial revolution (BIR) took
place when and where it did
emphasize the importance of the British industrial
revolution
focus on impact of the BIR on society
re-examine the question: did the BIR make people better
off or worse off
critical thinking--make this question more specific
rich? poor?

Hobsbawm ch. 1
what were conditions in England right before the
industrial revolution began?
why did the industrial revolution happen in this place at
this time?
change in the economy from the majority of people
employed in agriculture to the majority of people employed in
industry
a period of rapid technological change as one new
technology leads to another or requires another or make
possible another
To understand the industrial revolution we need to
look at:
Bigger patterns, mostly economic issues
How one step led to another (cause and
effect)
What was the impact of industrialization on
people’s lives
Why look at England? (note: Great
Britain=England+Scotland+Wales+Northern Ireland)
it had the first industrial revolution, copied by other
countries including the U.S.
since it was first it is the most interesting case study
of how technological revolutions start
it also had to invent as it went along how to manage the
social consequences of industrialization
Britain had the largest percentage of factory workers of
any country so their influence on politics is particularly
significant
Hobsbawm is British so he is also interested in how the
most powerful country in the world became a minor power, and
the consequences of that for life in England. We will be
mostly skipping those chapters.
Background:
Prehistoric Technology--agriculture was the invention that
allowed larger communities with division of labor, therefore
more progress
paleontologists find that early species of
humans, as much as 3 million years ago, used fire
and produced
simple tools. But in primitive societies there is
little division of labor so the work process tends to stay
very simple.
hunting and gathering seems to be an easy
life--12 to 19 hours of work a week--so why develop
agriculture?
less than 10 thousand years ago agriculture was
invented in northern Iraq, and within a few thousand
years independently in other parts of the world--China,
India, central America.
slash and burn agriculture did not make much
difference, because it cannot support large populations.
Irrigation
is the key to the development of cities because it supports 14
times the population on the same area of land. It takes
twice the labor as dry farming.
Ancient World--progress was limited by attitudes
towards technology in Europe and the Middle East
labor demands increased as a result of
technological advance, but it also allowed specialization--the
invention of government, writing, and
in general of civilization. This second revolution
happened in Egypt and Mesopotamia about 3000 BCE.
This meant the opportunities of a market, but
at first opportunities to do new things were very limited by
people's beliefs
belief that the physical world was
controlled by Gods who behaved irrationally (example: Mesopotamia)
slavery--you don't need labor-saving devices
if you have slaves to do the hard work
the attitude that practical life was beneath
the dignity of educated men (example: Hellenistic
Alexandria)
Plutarch
said of Archimedes: "Although his inventions had won for him
a name and fame for superhuman sagacity, he would not
consent to leave behind him any treatise on this subject,
but regarding the work of an engineer and every art that
ministers to the needs of life as ignoble and vulgar, he
devoted his earnest efforts only to those studies the
subtlety and charm of which are not affected by the claims
of necessity." (a
source)
Archimedes
The fall of Rome resulted in a near-complete collapse of
civilization
barbarian tribes took over
literacy was nearly lost
slavery became impractical and the idea developed
that it was immoral to hold Christians as slaves
civilization had to be rebuilt on a new foundation
(Christianity)
the only functioning organization left was the church
(Catholic)
The Middle Ages in Europe (700-1400 CE)--technological
progress and economic changes
Europe became more technologically
advanced than China
only after about 1350
during the middle ages (also known as the
medieval period) European technology began to progress
while the Chinese increasingly believed that innovation
was a bad thing.

Agricultural changes increased the
amount of food one farmer could produce:
The mouldboard
plow (8th century, also known as the heavy or wheeled
plow) turned the soil--needed on wet soils in northern Europe
required 6
to 8 oxen to pull so led to cooperative farming
PEM photo: Mouldboard Plow, National Museum of American History
2/3 of the fields produced food each year
instead of the old system where half the fields were left
fallow
Horsepower replaces oxen (widespread by 12th
century)--horse could work for more hours a day and moved 50%
faster
oats (oxen can work on grass alone while
horses need grain)
the
horse-collar (8th-9th century)--allows a horse to pull
4 or 5 times more weight.
Horse-collar
iron horseshoes (common by 11th century) allowed
horses to work on wet ground
the
stirrup made possible the mounted knight, creating a
demand for more and better horses
Feudalism gave farmers somewhat more freedom to
adopt new technologies:
--Manorial
System : the serfs (not a slave, but bound to the
land--cannot move away) lived in a village and farmed the
land communally, giving a share of their labor and the crop
to the knight
--the knight and his family lived in the
castle and had responsibility to protect the serfs and to
fight when called up by the king
--theoretically the king owned all the land
and gave the lords the right to use it in return for
military service, the lords then divided it up among knights
on the same deal
--such
government as there was was provided by the knights
and lords
--the farmers had
some opportunity to better themselves by improving farming
practices
Water Power began to be used in place of human
muscle:
invented in Roman times but used only rarely
through the 5th century
Spread of the water
wheel in the 8th and 9th centuries
In 1086 the Domesday Book lists 5624 mills in 3000 English communities--an
average of one mill for every 50 households
first
mills were floating mills or mills attached to
bridges. They first had undershoot wheels (20-30%
efficient), then overshoot (50-60% efficient, 13th century)
with the water directed by a canal or a wooden millrace
the invention of the cam allows the
conversion of rotary motion into reciprocating motion
new uses for water power:
around 1000: fulling
wool cloth, beating hemp, water driven trip hammers to break
up iron ore
around 1100 water powered bellows,
edge runner wheels to crush olives for oil
around 1200 saw mills that used water
power both to power a rotary saw and to feed in the log
around 1300 water powered grindstones,
pumps to remove water from
mines
damming a river for water power--1177
Toulouse had 3 dams with 43 mills. The largest dam was
1300 feet long
windmills (12th century) used in areas where land was
flat or streams froze in the winter
Christianity
and attitudes towards technology in the Middle Ages
motivation to go out and spread Christianity
God no longer inhabits nature
Man's dominion over the earth--new attitude
monasteries developed and spread technology
because they needed it to be self-supporting on marginal land
and because they believed work was virtuous
monks work with their hands--the first
intellectuals who got their hands dirty (
The Cistercians )
Christianity prohibited the owning of
Christians as slaves so slavery became much less common
Cathedrals were a technological achievement
with a religious purpose--competition to build taller both for
civic pride and because people saw it as getting closer to God

The printing press allowed knowledge to
spread more quickly and reliably:
medieval books cost $2000-10,000 in today's
money
the first universities developed in the
middle ages, and the demand for books was so high that some
workshops had a kind of mass production with one person
reading and a number writing
paper was already mass produced, the screw
press and oil-based inks used for wooden block prints
Gutenberg's key innovation (in 1452) was
moveable type (more
history )
by 1483 the same amount of money would
produce 3 hand copies of 1025 printed copies
the cost of a book dropped to a few hundred
dollars in today's money
by 1500 8 million books published--equal to
total previous world output
impact:
students didn't have to spend all their time
memorizing the books
more books available meant it was easier to
compare books and notice contradictions
more accurate and faster transmission of
knowledge
people read the Bible for themselves,
leading to the reformation
Luther takes his stand in 1517--argues
that we are saved by God's grace not by good works and that
everyone has the right to interpret the Bible for themselves
in 1531 Henry VIII breaks England away
from the Catholic church
Copernicus
published De Revolutionibus Orbis Celestium in
1543. He was a priest motivated by the need for calendar
reform, but his argument that the earth goes around the sun
(instead of vice
versa) started the downfall of Aristotelian science
Kepler
published the theory that the planets move in elliptical
orbits in 1609.
Galileo
published his defense of the Copernican system in 1632 and his
new physics in 1638. Galileo is most important because
he put into place a new scientific method in which scientists
argued from experiment and from his observations with the
telescope, not from logic alone.
Newton
published the law of universal gravitation in 1687. He
was slowed down a bit because he had to invent calculus in
order to show that his theory worked.
Exploration:
the problem of navigation was not solved
during the age of exploration
magnetic
compass introduced in 13th century, but knowing which
way you are going doesn't help much if you don't know where
you are
more careful map-making was the main
improvement of the 14th and 15th centuries, particularly
knowledge of the winds
minor improvements in methods for
measuring latitude in 15th century
the problem of measuring longitude was not
solved until the mid to late 1700s ( story)
in 1340 the Muslims cut off overland trade
to Asia and Europeans start exploring outside the
Mediterranean
slow exploration down the coast of Africa
until Bartholomew Dias rounded the Cape of Good Hope in 1487
Columbus underestimated the circumference
of the earth and reached America in 1492
the full
rigged ship (about 1500--only one of Columbus's ships was
the new design)
multiple masts and more than one sail on
each mast
rudderpermanently attached to a stern post instead of a
steering oar
rounded shape
military technology was also critical,
because of the fighting to control sea routes
primitive cannon
about 1325 used carved stone balls and exploded a lot
iron cannonballs introduced 1350, corned
gunpowder for more even explosion about 1420
cannon became safe enough to use
on a ship about 1500
very quickly warships began carrying large
numbers of cannon--England rose to power partly because they
were more successful in making iron cannon (because they
happened to have high-phosphorous ore)
