  • Calculus, Logic, Chemistry, Physics
  • Production of goods and services
  • Still largely artisans and guilds

  • Rapid advances in all areas. Biology develops
  • Production of goods and services
  • Industrial revolution railroads for distribution
  • Engineering
  • Many core principles developed
  • Ability to draw up specifications based on an
    understanding of the science and engineering
  • Automobiles, telegraph, telephone, electricity,
  • Mechanical computing Punched cards at IBM

Early 20th Century
  • Early concepts underlying computer science
  • Information theory, concepts of computability
  • Mass production
  • World wars Horror, but impetus for innovation
  • Key disasters See coming slides
  • Quebec bridge Engineering in Canada
  • New London School Explosion Engineering in the

Quebec Bridge Disaster Aug 29, 1907
  • Quebec Bridge is (still) the longest cantilevered
    span in the world 550m
  • Le pont de Quebec est le plus long en porte-
    a-faux au monde 550,
  • Collapsed during construction in 1907
  • Lepont sest effondré pendant sa construction en
  • 75 workers killed / 75 morts

Quebec Bridge Disaster - 2
  • Bedrock location determined span length
  • Theodore Cooper (New York) hired as consulting
  • Responsible for design and guaranteeing bridge
  • Beams, columns, shipped from Pennsylvania
  • Two halves built from each shore to meet in the

Quebec Bridge Disaster - 3
  • As south side reached 200m, some compression
    members started bending
  • Serious Site engineer McLure
  • Construction suspended
  • Exchange of telegrams with Cooper for 3 weeks
  • McLure then travels to New York
  • Cooper convinced
  • Add no more load till after due consideration

Quebec Bridge Disaster - 4
  • Chief site engineer Hoare mistakenly resumed work
  • Collapse
  • Royal commission findings
  • Serious errors in design
  • Actual stresses above safe limits
  • Consulting engineer Cooper rarely visited
  • Chief site engineer Hoare not technically
    competent to supervise
  • Communication problems

Quebec Bridge Disaster - 5
  • A realization developed that only competent,
    ethical people should practice engineering
  • Professional engineering licensing introduced
  • Ritual of the Calling of an Engineer (iron
    ring) instituted
  • Another collapse in 1916 when hoisting new middle
    section into place kills 13
  • Bridge finally completed in 1917
  • Still in use, although a modern autoroute bridge
    is now next to it

Quebec and Pierre Laporte bridges today
New London School Explosion March 1937
  • Gas explosion due to faulty engineering killed
    over 295 students and teachers
  • Prompted Texas and other states to require
    engineering licensure

Some professions requiring a license
  • Engineering / Génie
  • Because most designs (buildings, airplanes,
    power systems) can cause harm if they fail.
  • But not everybody has a license!
  • Medicine, nursing, dentistry etc. / Médecine,
    sciences infirmières, dentisterie, etc
  • Malpractice can kill
  • Teaching / enseignement
  • Children are vulnerable
  • Geoscience /géosciences Chartered
  • Fake or wrong results can cause great financial

Trades requiring a license
  • Plumbing
  • Electrician
  • Hairdressing
  • A trade does not require a university degree

Professions not requiring a license (yet)
  • Most sciences
  • Peer review is used for quality control
  • University teaching (except of some licensed
  • Computer programming
  • The field grew too large before anybody thought
    about this
  • A lot of software is not safety critical

Question for discussion / à discuter
  • Should some computer science practice also be
    subject to a license (restricted practice?) just
    like engineering
  • Est-ce que certaines pratiques de l'informatique
    devraient également être soumis à une licence
    (exercice restreint?)

Recent and Upcoming DevelopmentsConverged
pocket devices
  • Until recently you might need to carry
  • Cell phone, GPS, calculator, iPod, dictionary,

    radio, credit/debit card substitute, garage door
    opener, language interpreter, integration with
    cordless phones (like Femtocells), microscope,
    telescope, facial recognition
  • But
  • Using these devices while driving is a problem
  • They can interfere with solitude, quiet and
  • Cameras in cell phones present privacy issues

Recent and Upcoming DevelopmentsArtificial
Intelligence and Robotics
  • Artificial intelligence can solve a number of
    expert, difficult tasks
  • Machine translation is becoming closer to reality
  • Robotic devices are often special-purpose
    devices, and may require AI to function
  • Can operate in space, in hazardous situations, or
    perform routine physically laborious tasks
  • Machine Learning and Data Mining methods or
    algorithms enable adaptive systems
  • Can help us understand patterns in data, e.g. for
    weather and business forecasting, detecting
    security violations etc.

  • Restoration of abilities, productivity and
  • Screen readers and scanners for the blind
  • Speech recognition for the deaf
  • Prosthetics with motion sensors

What other innovation is coming?
  • Encrypted medical records on chips attached to
    medical bracelets or on your cell phone
  • Biology, electrical engineering and computer
    sciences will combine new ways to insert devices
    into the body
  • Communicate directly with the brain
  • Control the world by thought
  • Monitor health constantly

Discussion Questions
  • What changes and new developments do you expect
    in the next 50 years?
  • Top Hat Monocle In 2-3 words name the technology
    you are most looking forward to / En 2-3 mots
    nommer la technologie à laquelle vous êtes le
    plus d'impatience
  • How will life be different than it is today?

But what problems do we need to deal with?
  • Criminals, terrorists and hostile governments
    also have the power of computing at their
  • Combating these requires restrictions and
  • Personal data can leak out, reducing privacy
  • Some people become less social due to interacting
    more and more with technology
  • Fire was a gift when our ancestors discovered it
    but it has also caused a lot of destruction
