21. Enough about me! Why are you here?

22. 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

23. Training Good Engineers EE and CE aren’t our only goals! – Critical Reading – Critical Reasoning Ask questions! Think through problems! Challenge assumptions!

24. 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

25. Bloom’s Taxonomy Evaluation Synthesis Analysis Application Comprehension Knowledge

27. WHAT IS ECE?

28. What is Electrical and Computer Engineering? Break into groups…

29. 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

30. 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

31. 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

32. 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

33. Some mistakes along the way

34. And also some wonders

35. 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

36. 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

37. The biggest break through… 1947 Shockley, Bardeen, and Brattain invent the transistor

38. 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

39. CS and CE What are the disciplines? – Computer Engineering? – Computer Science?

40. 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

41. 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

42. 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.
