Why are you here?

So what are the goals of this class?

• To help you understand the field electrical and computer engineering– Its past– Its present– Its future

• To introduce you to the fundamental ideas of our field• To provide hands-on experience in the laboratory• To discuss topics related to the broader field• To introduce the process of research and design• To build skills for collaborative work, problem solving, and

communication

Training Good Engineers

• EE and CE aren’t our only goals!– Critical Reading– Critical Reasoning

• Ask questions!• Think through problems!• Challenge assumptions!

Active Learning

• After 2 weeks we tend to remember:– Passive learning

• 10% of what we read• 20% of what we hear• 30% of what we see• 50% of what we hear and see

– Active learning• 70% of what we say• 90% of what we say and do

WHAT IS ECE?

What is Electrical and Computer Engineering?

Break into groups…

Some History

• 1750 – Benjamin Franklin and the lightning rod, realizes electricity as a fluid

• 1785 – Coulomb discovers electrical charges• 1800 – Volta (re)invents the electric battery• 1816 – Henry discovers inductance• 1820 – Ampere discovers current-induced

magnetism

Some History

• 1827 – George Ohm quantifies the relationship between electric current and potential difference

• 1831 – Michael Faraday discovers electromagnetic induction

• 1837 – Morse invents the telegraph• 1854 – Boole introduces the algebra of logical

functions

Some History

• 1873 – James Clark Maxwell published a unified theory of electricity and magnetism.

• 1876 – Bell invents the telephone• 1877 – Edison invents the phonograph• 1879 – Edison invents the incadescent lamp

Some History

• 1882– Edison switches on the first large-scale grid in NYC– Darmstadt University forms an EE department– MIT begins offering an EE specialization in physics

• 1886– The University of Missouri opens the first EE

department in the US

Some mistakes along the way

And also some wonders

Some history

• 1888 – Henrich Hertz demonstrates the transmission of radio waves with a spark-gap transmitter

• 1897 – Karl Ferdinand Braun introduces the cathode ray tube

• 1904 – John Fleming invents the diode• 1907 – Robert von Lieben and Lee De Forest

invent the triode

Some history

• 1920 – Albert Hull develops the magnetron• 1936

– The invention of radar– Turing’s thesis on computation

• 1941 – Konrad Zuse presents the Z3 a fully functional and programmable analog computer

• 1943 – Tommy Flowers designs the Colossus, the first digital computer

• 1946 – The ENIAC begins the era of computing

The biggest break through…

1947

Shockley, Bardeen, and Brattain invent the transistor

So where are we now?

• ECE– As physics begat EE, EE has begotten CE.

• CS?– CS and ECE have a lot in common, in many places

they are taught in unified departments.– CS differs in its background, typically pure CS

departments are derived from Mathematics

CS and CE

• What are the disciplines?– Computer Engineering?– Computer Science?

What it isn’t

• "What would we like our children- the general public of the future—to learn about computer science in schools? We need to do away with the myth that computer science is about computers. Computer science is no more about computers than astronomy is about telescopes, biology is about microscopes or chemistry is about beakers and test tubes. Science is not about tools, it is about how we use them and what we find out when we do."

-- Ian Parberry

What it isn’t

• A confusion of even longer standing came from the fact that the unprepared included the electronic engineers that were supposed to design, build, and maintain the machines. The job was actually beyond the electronic technology of the day, and, as a result, the question of how to get and keep the physical equipment more or less in working condition became in the early days the all-overriding concern. As a result, the topic became —primarily in the USA— prematurely known as "computer science" —which, actually is like referring to surgery as "knife science"— and it was firmly implanted in people's minds that computing science is about machines and their peripheral equipment.

-- Edsger Dijkstra

What it really is

• Computer science is the study of the theoretical foundations of information and computation and of practical techniques for their implementation and application in computer systems. Computer scientists invent algorithmic processes that create, describe, and transform information and formulate suitable abstractions to model complex systems.

• Computer engineering is the process of analyzing, designing, and integrating the hardware and software systems needed for information processing or computation. Computer engineers are saddled with the difficult tasks of modeling, designing, and analyzing cyberphysical systems which solve interdisciplinary problems in a wide variety of domains.
