Gasoline

NOTE: This is an abbreviated lecture

Mid-1800’s, oil was found in open ponds in parts of the US
This oil was taken to chemists for analysis, commercial applications were suggested
Gasoline was originally a by-product of refining, it was disposed of as it was dangerous
Early 1900’s, electric lighting replacing kerosene, internal combustion could increase demand for gasoline
Gasoline: low [...]

19th Century Popular Science

Late 19th century possibility of life on Mars

Astronomy borrowed representational tools from geography (e.g. mapmaking, travelogues)
Images of geometrical lines in the landscape implied canals to some people
There was considerable discussion of this debate in the popular press
Life on Mars, plurality of worlds thesis
Information about Mars was conveyed through maps
Astronomers and techniques from geography: travel [...]

Mathematical Education and Industry

NOTE: THIS SUMMARY IS ABBREVIATED

by 1800 math teaching in England was better than math teaching in France
in addition, after 1750 British math was oriented towards practical teaching, French towards developing calculus and astronomy
The British market was less regulated and less controlled by guilds
Both the British and the French were increasingly influenced by markets, and markets [...]

Science and Industry in the 18th and 19th Centuries

Steam Engine and Thermodynamic Theory

Thermodynamic theory and steam engines
Vacuum and atmospheric pressure
Christian Huygens & Denis Papin (1673) small charge of gunpowder exploded in cylinder, vacuum causes cylinder to be pushed downwards by air pressure, lifting 1600lbs through 5 feet
Steam engine: piston covers chamber, steam pushes it up, cooling the steam causes it to condense, creating [...]

Part 3: The Industrial Revolution

The Factory System

Many steps between raw material and finished textile
Cotton had to be ‘carded’, straightened out into fibers that could be stretched and twisted together to form thread
Threads were then woven, bleached, dyed and printed
Richard Arkwright added a crank for removing the fibers from the cylinder
James Hargreaves Spinning Jenny was the [...]

Part 2: The Industrial Revolution

The Industrial Revolution

The industrial revolution was characterized by a switch from craft work by agrarian communities to manufacturing using machinery by urban industry
The industrial sector came to dominate the economy over the agricultural sector for the first time since the beginning of civilization
After industrial revolution technological innovation was rapid, this influenced: Incomes, employment, skills, social [...]

Part 1: The Industrial Revolution

Seventeenth Century Science

slowdown in the development of science in England in the late 17th century
Bernal attributes this slowdown primarily to social and economic factors, namely a new class of merchants had arisen who were less enterprising and more interested in secure investments like land
There are other explanations:
Newton’s science was close to complete and [...]
