engineering• Modern electrical engineering

– From currents to signals– Engineering solutions

• Courses

EE101 Week 1 5

What Is Engineering?

• Engineering is the science of providing viable solutions to outstanding problems– Science– Outstanding problems– Solutions– Viable

• Q: Are babies engineers? (Or, is engineering inherent in human nature?)

EE101 Week 1 6

Birth of Engineering

• Designing skyscrapers• Building skyscrapers• Designing machines that build skyscrapers• Building machines that build skyscrapers• Designing machines with which to design

machines to build skyscrapers• Building machines with which to design

machines to build skyscrapers• …

EE101 Week 1 7

Birth of Engineering“… so why can’t a man catch a fish?” – old joke• Catching a fish• Making fishhooks• Building machines that make fishhooks from

metal rods• Building machines to mine metal ores from the

earth• Finding metal ore deposits to mine and make

fishhooks• …

EE101 Week 1 8

Birth of Engineering

• Seeing• Grabbing• Crawling• Walking• Talking• Talking back• Q: Are babies engineers?

EE101 Week 1 9

Birth of Engineering• Engineering is inherent in human nature

– The ultimate revenge of the nerds• Human species explores the evolutionary niche of high intelligence

– Adaptation– Problem solving

– Human intelligence is equipped with basic logical reasoning and imagination skills to figure out solutions to the problems they face

• Everyday problems that require solving• Evolving problems with evolving species

– The popular term for engineering is “using tools”• Tools keep getting more and more sophisticated• Technology developments for newer problems

• It becomes an academic discipline when carried out systematically using the scientific method

EE101 Week 1 10

Sailboats: An Engineering Feat• Sailboats require thousands of

parts designed to operate towards a specific set of objectives

– Floating on water– Moving toward a destination– Controlling the movement– Carrying cargo that makes it worth

• designing and building the boat• sailing to potentially dangerous

destinations• Historical development

– Boat from 6300BC– Sails on boats since 4000BC– Extensive sailing since 1500BC– Merchant ships carrying 1,000

tons of cargo in 100BC– Viking ships travelling all over in

1000AD

EE101 Week 1 11

Engineered Civilizations• Pathways• Dirt roads• Stone roads• Paved roads• Railroads• Tunnels• Bridges• …

• Bare feet• Basic shoes• Saddles on burros and

horses• Horse-driven carts and

wagons• Cars• Locomotives• Trains• …

EE101 Week 1 12

Development of Electrical Engineering

• Electricity– Benjamin Franklin and his kite (1752)– Edison’s electric bulb (1879)– Morse’s telegraph (1837)– Bell’s telephone (1876)– …

• Leaps forward during the WWII– Radar– Sonar– Cryptography– …

• The age of computers– The transistor

• Point contact transistor (Bell Labs, 1947)– Shortly after replaced by the bipolar transistor

• Transistors for portable radios (Texas Instruments, 1954)

• Television sets with transistors (Sony, 1960)– Electrical computation

• ENIAC (The University of Pennsylvania, 1946)• Personal computer (1970’s onward)
