  5. Computer Sciencehttp://www.cs.princeton.edu Professor Jennifer Rexford ’91

  6. What is Computer Science? Information

  7. What is Computer Science? Creating, representing, manipulating, storing, searching, visualizing, and transferring information.

  8. Computers are in Everything... • “A camera is a computer with a lens” • “A cell phone is a computer with a radio” • “An iPod is a computer with an earphone” • “A car is a computer with an engine and wheels”

  9. Networks of Computers are Everywhere • Communication: e-mail, chat, ... • Searching: Google, Yahoo • Shopping: eBay, Amazon, ... • Mapping: online driving directions, Google Earth • Playing: online poker, video games, ... • Sharing: peer to peer file sharing

  10. CS Studies How Computers Work and How to Make Them Work Better • Architecture • Designing machines • Programming languages and compilers • Telling them what to do • Operating systems and networks • Controlling them and communicating between them • Graphics, vision, music, human-computer interaction, information retrieval, genomics, ...: • Using them • Artificial intelligence and machine learning • Making them smarter • Algorithms, complexity • What are the limits and why

  11. Breathe Life Into Matter

  12. Breathing Life: A Modern Perspective • “Matter”: Atoms, molecules, quantum mechanics, relativity … • “Life”: Cells, nucleus, DNA, RNA, … • “Breath life into matter”: Computation

  13. Computational Universe

  14. Important Distinctions Computer Science vs. Computer Programming (Java, C++, etc.) vs. Concrete Implementations of Computation (Silicon chips, robots, Xbox, etc.) Notion of computation

  15. Example: • Web crawler • Start with a base list of popular Web sites • Download the Web pages and extract hyperlinks • Download these Web pages, too • And repeat, and repeat, and repeat… • Web indexing • Identify keywords in pages • Identify popular pages that many point to • Web searching • Respond in less than a second to user queries

  16. New Biology Microarrays Pathways Example: Computational Biology Old Biology

  17. The CS Department at Princeton • Around 30 BSE majors each year • Plus ~10 AB majors and 15-20 certificates • Who go to • Grad school • Software companies both large and small • Wall St, consulting • 29 faculty • Theory • Operating systems & networks • Programming languages • Graphics, music, and vision • Computational biology & scientific computing

  18. Curriculum • Introductory courses • COS 126: General CS (taking by all BSEs) • COS 217: Systems Programming • COS 226: Algorithms & Data Structures • Eight departmentals, two each in • Systems • Applications • Theory • Courses in other departments • Independent work

  19. Departmentals: Two of Each • Systems • operating systems, compilers, networks, databases, architecture, programming techniques, ... • Applications • AI, graphics, vision, security, electronic auctions, HCI/sound, computational biology, information technology & policy... • Theory • discrete math, theory of algorithms, cryptography, programming languages, computational geometry, ... • Courses in other departments • ELE, ORF, MAT, MOL, MUS, PHI, PHY, PSY, ...

  20. Other Options • Certificate in Applications of Computing • 217, 226, two upper-level courses, computing in independent work • See Professor Steiglitz • AB instead of BSE • Same departmental requirements • Different university requirements • Two JP's and a senior thesis vs. one semester of IW • Foreign language vs. chemistry • 31 courses vs. 36

  21. Faculty Projects: Laptop Orchestra • Plork is the Princeton Laptop Orchestra • Freshmen Seminar, joint between Music and COS • Students invent their own musical instruments • Compose and perform music on laptops connected to speakers, keyboards, tablets, and other devices

  22. Faculty Projects: Bio-Informatics Analyzing and visualizing interactions between genes and proteins Chromosomal Aberration Region Miner Detecting differences in genes

  23. Faculty Projects: Display Wall

  24. Faculty Projects: PlanetLab • Open platform for developing, deploying, and accessing planetary-scale services • Consists of more than 700 machines in 25 countries • An “overlay” on today’s Internet to test new services • Running many novel services for real end users

  25. Faculty Projects: GENI • Global Environment for Network Innovations • Experimental facility for a “do over” of the Internet PC Clusters Wireless Subnets ISP 1 Programmable Routers ISP 2 Dynamic Switches

  31. Undergrad Projects ACM Workshop on Digital Rights Management, April 2002

  32. Brian Tsang '04, salutatorian

  33. CRA Outstanding Undergrad Award • Two awards per year • For top undergraduate nationwide • CRA award in 2008 • Rachel Sealfon • Research in bio-informatics • CRA award in 2007 • Lester Mackey • Research in programminglanguages and architecture

  34. Questions? • For more info, check out the CS web site • Web site: http://www.cs.princeton.edu • Especially the “Guide for the Humble Undergraduate” • Pick up copies of • The Guide • Certificate program • Independent work suggestions

  35. Other Computer Science Resources • Association for Computing Machinery (ACM) • http://www.acm.org • IEEE Computer Society • http://www.computer.org • Computing Research Association (CRA) • http://www.cra.org

  36. Conclusions • Computer science as a discipline • CS is about information • CS is about breathing life • CS is everywhere • Computer science at Princeton • BSE degree, certificate program, and AB degree • Core CS courses and interdisciplinary connections with psychology, biology, music, art, public policy, etc. • Courses in a wide range of areas from operating systems to computer music, from computational biology to computer architecture, etc.

  37. Picking Your Major • So many engineering majors, so little time • How to choose the one that is right for you? • See what excites you in this course • Exposure to all of the engineering disciplines • Understanding of the synergy between them • E.g., digital camera draws on physics, EE, and CS • Do choices close a door, or open a window? • Many opportunities to take courses in other departments • Boundaries between disciplines is a bit fuzzy • What you do later may differ from what you do now • All of the departments give you a strong foundation
