  3. Top Ten Reasons for Becoming a Computer Scientist • I thought it would be a great way to learn how to type. • I no longer need to sleep at night. Now I just take naps while I wait for the system to respond to my commands. • The Binary Number System. • The fact that once I become a computer scientist, I can financialy ruin Bill Gates to the point that Babygirl Gates has to go to community college. • Since we are on the money subject, as tempting as most low wage, benefitless jobs are, I am opting for the big bucks of computer science.

  4. Top Ten Reasons for Becoming a Computer Scientist 6. Getting to work on the dingy, dirty, oily, filthy, keyboards in the student computer lab. 7. Have I mentioned the Binary Number System yet? 8. There is nothing like a tension headache caused by staring at the monitor. 9. Graduating Suma Cum Lade because I know how to hack into the system and change my grades. 10. I want to be a nerd like the teacher. courtesy: Becky Zagurski

  5. The Past • The field of computing now is 50 years old • Electron was discovered in 1895 • First electronic computers were built in 1940’s • For large scientific calculations • Calculate trajectories • Code breaking • In 1950, IBM and Univac bet computers would become the engine to run large businesses • News Media called them “electronic Brains” • Projected number of machines - only a dozen

  6. The Past ctd.. • The first programming languages • Algol, Fortran, Cobol and Lisp • First Operating System designed in 1960’s • First Hand calculator appeared in 1972 • Computer chip appeared in late 1970’s • IBM PC in 1981 • ARPANET ==> World Wide Web ==> Internet • 1970 1992 now

  7. The Past • Main Frame computers have become obsolete now • Over 70% of households in US have home computers • The Great Big Promise of Artificial Intelligence • In 1950 Turing believed that by 2000 we will have computers that would not be distinguishable from humans • Chess playing machines would beat world masters by 1980 • But Kasporav could not be beaten by a computer until late 1990’s • In 1980, Bell Labs believed that Unix would be the world dominant operating system • In 1982, Bill Gates thought 640K of RAM would suffice for many personal users for years to come

  8. The Present • We are all connected by Email, world wide web • We can chat with a friend halfway around the world for free • We can play games with a remote friend • We can instantly exchange our pictures over the web • We can monitor what happens at our home from any remote location • We can pay our bills over internet

  9. The Present • Our cars, homes, and all gadgets we wear are computerized • Technology is the fabric of our life • If all computers were taken out of commission the world will stop working instantly • We have become socially isolated and have form relationships with our virtual friends • Fighting terrorism using technology

  10. Our Universities • Carnegie Mellon is the “best” computer science program in the world. • Many inventions came out of CMU • CMU is the home to Nobel prize winners • Lets take a look at some interesting research going on at CMU

  11. The Future • By 2047, almost all the information will be in cyberspace • Physical objects, humans, buildings, processes and organizations • We can communicate with one another remotely using all our sensors • Computers will be 100,000 times powerful than today • If Moore’s Law holds (doubling every 18 months), then computers will be 10 billion times more powerful than today • Algorithms speeds have improved as the same way as hardware

  12. The Future • Suppose you want to store all you do in a lifetime • Read Text (60-300 GB) • Speech Text (15 GB) • Speech (compressed) - 1.2 TB • Video (compressed) - 1PetaByte - million GigaBytes • What is the storage cost of all this?

  13. The Future • Much of the world population is illiterate • Multiple Language communication • Understand Video , Music, Gestures • Computers Teaching Kids how to Read • Robots enable by computers • Video and Audio synthesis • Entire movies and plays to be synthetically generated • Body Nets • Artificial eyes • Remote controlled mouse • By 2010 speech UI is available in any device you can think of - Cars, radios, phones, toys

  14. The Future • Computers disappear to become components for everything • Zero cost system on a chip • One chip fully networked systems • Appliances talking to each other • Merge of telephone and Internet

  15. The Future • Predictions gone wrong • 1943- Thomas Watson predicted only 5 computers would be needed for the entire country • 1977 - CEO of Digital - There would be no use of home computers • 1995 - VP of Bellcore - if we cannot predict the net what good are we? • Some form of voice input and output will be common by 1978

  16. Careers in Computer Science • Artificial Intelligence -- Develop computers that simulate human learning and reasoning ability. • Computer Design and Engineering -- Design new computer circuits, microchips, and other electronic components. • Computer Architecture -- Design new computer instruction sets, and combine electronic or optical components to provide powerful but cost-effective computing. • Information Technology -- Develop and manage information systems that support a business or organization. • Software Engineering -- Develop methods for the production of software systems on time, within budget, and with few or no defects.

  17. Careers in Computer Science • Software Engineering -- Develop methods for the production of software systems on time, within budget, and with few or no defects. • Computer Theory -- Investigate the fundamental theories of how computers solve problems, and apply the results to other areas of computer science. • Operating Systems and Networks -- Develop the basic software computers use to supervise themselves or to communicate with other computers. • Software Applications -- Apply computing and technology to solving problems outside the computer field - in education or medicine, for example.

  18. The Conclusion • Future is hard or impossible to predict • We do tend to predict future as an enhancement of the present • If we can imagine we can build it • But something's just cannot be predicted • Eg: internet, home computers • One thing is certain • Future is exciting • We all are part of it
