Lienhard 14
War was the place where the power that
technology could provide began to be seen as a mixed blessing
how did modern era enthusiasm for technology
come to an end?
technology gives us more and more power, maybe too much
for humans to handle well
Lienhard tells us historical stories to reflect on the
motivations of people developing technologies for war.
Should ethical issues apply?
- personal ethics--what jobs would you take
- professional ethics--is something so harmful to
society that the professionals involved shouldn't develop
it?
- communal ethics--what do we as a society not want to
do because of the harm it might cause
- ethics should be more than: something just seems too
horrible. That is not a good way to make a decision,
because that can change (or not)
- just war theory: war is ethically justified only in
certain circumstances, you must conduct war in a way that
harms the fewest possible civilians
Consider the near future example of robot
soldiers:
- a machine that will take action in war at a distance
from human beings
- machine can be remotely controlled
- or make its own firing decisions--autonomous
- robot soldiers would mean fewer casualties
- we already have remote controlled aircraft (drones)
- we don't trust machines
- emotional detachment--kill too easily because it
feels like a video game
- war should be men facing men, this is not a fair
fight--we aren't putting ourselves at risk
- more wars because there wouldn't be human
casualties on our side
constant decisions in modern warfare so we are talking
about autonomous robot soldiers that make their own decisions
- GA Tech professor
says he can make robot soldiers that will follow the
rules of war better than human soldiers
- what worries him is that countries will go to war
more quickly if they can do it without human causalities
- how much autonomy would you give robots, and does
this lead to risk of them taking over the world
- robots taking jobs way from people -- the play
RUR (Rossums Universal Robots) predicted this in
1921
Why is war a
special case when thinking about the progress of
technology
- different purpose: not to make our lives
better, at least not directly
- marketed to government, not to consumers
- military technology doesn't have to
compete in the free market
- the government will fund military
technologies if useful enough even if very expensive
- urgency
is high, special teams of researchers are pulled
together for a crash program

When did
technologies developed during a war
start to make a difference?
The Civil War was significantly impacted by
technology, particularly railroads and more accurate rifled
guns. The first step towards a machine gun, the Gatling
gun, was tested but not widely used.
Maxim's invention of the first machine gun:
- motivated by profit--the US was not in a war
- in 1885 he produced a gun that fired 666 rounds a
minute
- the Russians bought large numbers and showed their
effectiveness
- he also predicted the importance of airplanes to war
The inventor of dynamite, Alfred Nobel, later founded a
peace prize, but earlier in his life he said:
"Perhaps my factories will
put an end to war sooner than your congresses: on the day
that two army corps can mutually annihilate each other in a
second, all civilized nations will surely recoil with horror
and disband their troops." (source)
World War I started in 1914, US entered April
1917, Armistice Dec. 1918.
- The war quickly settled down to a trench
warfare stalemate due to the use of machine
guns and barbed wire--technology seemed to be the
only way out.
- deaths seemed particularly meaningless
when it was so difficult to make any progress
- as well as airplanes and poison gas, tanks
and submarines were developed into useful weapons
- The war therefore led to the first major
wartime efforts to develop technology for military use
French tank
Poison
gas
- A few months after the war began the
French apparently used gas against the Germans and the Germans
retaliated in kind.
- In the 9th month of the war the Germans
released a cloud of chlorine gas--which causes choking--on
French troops who retreated in panic, leaving behind
perhaps 5,000 dead. A four mile gap in the line was
opened, but the Germans had not brought forward enough
reserves to exploit it and the Allies repaired the break.
- At first troops wore makeshift masks of
handkerchiefs wetted with urine and tied over nose and
mouth.
- Germany was widely criticized for breaking the Hague
Conventions of 1899.
- In mid-1915 Germans started using
phosgene, which causes severe lung damage, and both sides
developed gas masks.
- By the end of 1916 a variety of weapons
were in use by both sides. Germans introduced
mustard gas--could cause burns to exposed skin even when a
soldier was protected by a mask.
- This quickly became a research race.
It started with the US
Bureau
of Mines working on adapting mining equipment.
- A central lab was created in fall 1917 at
American University--at peak employed 1200
scientists. Developed a new gas called Lewisite,
that poisoned through the skin, simpler ways of producing
mustard gas, and more
- Chemical Warfare Service created July
1918--university chemists and Bureau of Mines personnel
were given commissions.
- In all as many as 50 different gases were
used--poison-gas causalities 1.3 million with 92,000
deaths.
- After the war chemists were proud of their
contribution to the nation--wanted ongoing research.
Argued that chemical weapons were humane (and effective)
because they disabled soldiers rather than killing
them. They didn't get the continuing high level of
research they wanted.
- A strong reaction against the use of gas
took over instead. The Geneva Protocol--an
international protocol signed in 1925 prohibiting the use
in war of "asphyxiating, poisonous and other gasses" and
of "bacteriological methods of warfare."
- Poison gas research continued and poison
gas development eventually led to the invention of some of
the pesticides we use to control insects
- The treaty held through World War II but use of
poison gas is a difficult issue today. Fear becomes
an issue even when it is not used: seven
Israelis suffocated to death due to improper use of gas
masks during Iraqi attacks in the Gulf War.
We can make choices about
technologies
Poison gas was seen as
too horrible
what is
the role of the government in technological progress?
war is a time when the government role will increase
WWI:
- NACA
- Naval Research Lab
- NRC
The Navy also decided it needed to encourage research
- Thomas
Edison said he had a plan for preparedness but that
he was reluctant to discuss the terrible devices he had in
mind. War could be mechanized with labor-saving
devices
- In 1915 the Navy established the Naval
Consulting Board
- the board was to consist of "Civilian
Experts on Machines" who would originate ideas and
critically examine ideas submitted by others--11
professional societies each named two members. These
were engineers and business leaders, not scientists
- the Board had a big fight about building
its own laboratory, but the laboratory that was eventually
built continued after the war as the Naval
Research Laboratory
- the effort that got the most public
attention was a plan to screen inventions submitted by the
public--Edison believed that American inventors could win
the war
- 110,000 inventions were submitted, 110
deemed worthy of development, only one reached
production--an aircraft
simulator invented by W. Guy Ruggles (photo)
- one of the Board's largest projects was
trying to find new methods of submarine detection
- they also sponsored research on gyroscopic
stabilization, leading to the first primitive autopilots
for aircraft (Lawrence Sperry proved they didn't work too
well--at least not well enough for
the pilot to get romantic instead of flying the
plane)
World War I British Submarine
Meanwhile scientists felt unappreciated and the
National Academy of Sciences (an honorary society created
during the Civil War) established the National Research
Council in 1916 to show what science could contribute
- Scientists wanted to show how valuable
science is: George Ellery Hale (an astronomer) wrote: "I
really believe this is the greatest chance we have ever
had to advance research in America"
- they also focused on the problem of
submarine detection--German U-Boats sunk over a million
tons of Allied and neutral merchantmen in the first
quarter of 1917
- the NRC brought in professors from
universities to work on the problem
- a young mathematician named Max
Mason had the idea of a
listening device that could focus sound--he build
something that looked like a trombone
- the final device had a range of 3 miles
and was very successful. Similar technology was
developed for artillery ranging
- scientists felt they had proved the
scientific research approach to developing new technology
So then what was the impact of war on technology and
science?
WWI led to the government getting involved in developing
new technologies in a big way
It proved that scientific research can often come up
with new products on demand.
Another such story in
Europe:
Rockets are another product of the modern
dream (a
brief history of rockets)
- Jules Verne's novel From the Earth to
the Moon (1865), featuring a launch from a cannon in
northeastern Florida
- Konstantin Tsiolkovsky's work (influenced
by Verne) in Russia on the theory of rocket propulsion?
- in 1903 he published a book titled Exploring
Cosmic
Space
with
Reactive
Devices in which he laid out the mathematics of
orbital mechanics and designed a rocket powered by
liquid oxygen and liquid hydrogen. Recognized many
of the problems, eg. burning up during reentry, and
thought of multistage rockets (which he called rocket
trains). No attempt to experiment--he received
only one small grant. Saw spaceflight as
liberation from human limits and the first step towards
the perfection of human society.
- Robert Goddard's theories (1919 treatise A
Method of Reaching Extremely High Altitudes), and
experiments, starting in 1926, with small, liquid-fuel
rockets?
- In 1930 Goddard set up full time
research in New Mexico, attempting 41 launches, 31 of
them successful, in the next 11 years. His largest
rocket was 22 feet in length, fueled with gasoline and
liquid oxygen. After 1941 he couldn't get further
support, and he died in 1945.
- He was much laughed at and couldn't take
it, so he conducted his research privately, failed to
build an organization, suffered from lack of support,
and had little influence. He repeatedly failed to
get military funding (on the grounds that the U.S. had
no need for military rockets at that time), and while he
received over $200,000 from foundations, it was on a
year by year basis that made it difficult to undertake
large projects. His fame came only when space
travel began to look realistic--in 1960 the U.S.
government awarded his family $1 million for the rights
to use more than 200 of his patents.
The key to turning this enthusiasm into a
serious space program turned out to be government support, and
the Germans were the first to get it.
- the roots of this development are in an
society of amateur rocketeers inspired by a
German-speaking Rumanian schoolteacher and rocket
theoretician, Hermann
Oberth, who published The Rocket into Planetary
Space in 1923
-
The Society for Space
Travel (VfR) was founded in 1927, with Oberth as its
president
- by 1929 it had 870 members, including
Wernher von Braun, who had just graduated from high
school.
- It had two goals: popularize the idea of
flight to the moon and planets and perform serious
experiments in rocket propulsion.
- Oberth was a classic incompetent
theoretician (one of his colleagues said that if "Oberth
wants to drill a hole, first he invents the drill press"),
early efforts resulted in many explosions including one
that killed a member, Despite these problems, the society
successfully launched 87 small liquid-fueled rockets in
1931 from an abandoned WWI ammunition storage facility
(including one that set fire to a nearby police
station). Experiments continued at a slowing rate
until 1934, when the society went bankrupt
- Amateur research could only afford to go
so far: the VfR was funding only by dues and admission
charged to view launches. The leaders of the VfR
promoted the idea of rockets as weapons in hopes of
getting the funding they needed.
- The German army became interested in
rockets in 1929 as a way of getting around the treaty of
Versailles limits on the army
- In 1932 the German army assigned Walter
Dornberger to look into liquid-fueled rockets, and he
hired von Braun and a number of amateurs--but clearly to
develop a weapon, not space travel
- This led to the building of the V-2 intermediate
range ballistic missile, used against England.
- When the war was over von Braun arranged
to to captured by the U.S. not the Soviet Union and said
he wasn't a Nazi, he was only interested in space travel.

U.S. military interest was at first spotty.
- U.S. cold war strategy was based on
bombers carrying nuclear weapons. For one thing, it
was cheap, and Truman and Eisenhower both were reluctant
to increase the size of the government and distort the
economy by large-scale defense spending.
Substituting technological superiority for a large
standing army put a new weight on being ahead
- Project RAND
(an Air Force think tank) produced in May 1946 a report:
"Preliminary Design of an Experimental World-Circling
Spaceship" mentioned reconnaissance, weather, and
communications
- In 1951 RAND scientists visiting
Wright Field heard a briefing by James Lipp of Boston
University's Physical Research Laboratory about using
television
for satellite reconnaissance. The key
RAND reconnaissance people though the idea was ridiculous,
and set out to disprove it with pictures taken at 30,000
feet with 8mm movie camera lenses mounted to a 35mm Leica
camera loaded with coarse grain film and processed for
poor resolution. The pictures showed streets and bridges, convincing Amrom
Katz and others that satellite reconnaissance was
feasible.
- the army had von Braun working on medium
range ballistic missiles, the Air Force was working on the
Atlas intercontinental ballistic missile, and the Navy's
Naval Research Lab was doing a wide range of scientific
research on rockets--but none of these had high priority
or crash project funding
- Korean war led to more funding for
intercontinental ballistic missiles in 1951--Atlas--but
with funding only for a slow development process (at
Convair--even in FY 1954 Atlas got only $14
million). Only in 1954 was the decision make to give
it high priority
