Welcome to Computer Science! Dr. Mircea Agapie Office: SCIENCE 213-C agapie@tarleton.edu 254-968-0792
During the transition week (this week) we meet: Tue & Wed 9-11 AM Once the semester officially starts (August 28), we meet twice a week, only for the first 8 weeks: Mon & Wed, 12 12:50 PM
Do you have access to Degree Works?
Is your major declared as CS? You can see this in Degree Works:
Are you registered in a Math course? If not

Syllabus
We take attendance during the transition week!
Notebooks and note-taking Click on the first link Read the article Answer the following questions (in your notebook ):
Notebooks and note-taking Who take more notes, students who use laptops or those who use notebooks? Who learn more, students who use laptops or those who use notebooks? How is the paradox explained in the article? How soon after note-taking were the students examined? What is the other major downside of electronic notetaking?

A more complex Algorithm: Tic-Tac-Toe
OK, so what s the algorithm? Created by Peter McOwan and Paul Curzon of Queen Mary, University of London with support from EPSRC and Google. More at www.cs4fn.org
A philosophical problem ensues: Can all human intelligence be described algorithmically?
Try developing a similar algorithm for the second player (0)
And now, an example of an algorithm implemented directly in hardware!
How would you use an adder to solve a new problem: Multiplication by 2? What do we mean by this? a Black Box 2 a What hardware should go inside the Black Box?
Solution a a+a = 2 a Congrats, you have just implemented an algorithm directly in the hardware!
Algorithm: Multiplication by 3 a 3 a Black Box Build a circuit with one input a, that produces 3 a at the output.
Solution a 2 a a+a+a = 3 a
Algorithm: Multiplication by 4 a 4 a Black Box Build a circuit with one input a, that produces 4 a at the output.
Thanks to a new bike-share program, getting around campus gets easier this fall at TSU! The program rolls out the first week of the fall semester and includes 35 bicycles at six locations: Centennial Hall Horticulture Center Lillian Street Commuter Parking Lots P41 and P20N (near the water tank and intramural fields). Hunewell Ranch Annex (out of town)
Seven-gear cruiser bicycles by Zagster feature adjustable seats, front and rear lights, a U-lock and handlebar basket. All bicycles are equipped with a flexible lock that riders can use for the duration of their rental to lock and unlock the bike anywhere along their trip. Riders can take bicycles off campus and into the Stephenville community. Registering for the bike-share program is simple. Riders sign up by downloading the Zagster mobile app, available for both iphone and Android. To use the app, riders enter the unique ID number found on the bike they wish to use. An access code for the lock box is then provided. Riders can checkout a bike for free for up to three hours. Rides over three hours are charged an additional $3 per hour up to $24 or for eight additional hours. If a bicycle is kept for more than 24 hours, a $25 fee is assessed. Complete details about Tarleton s bike-share program, pricing, locations on campus and FAQs are available at www.zagster.com/tarleton. Users also can view a How to Ride with Zagster video on YouTube: www.youtube.com/watch?v=izqkpk3k3jw. As a reminder, bicycles are considered vehicles in the state of Texas. Riders are liable for any injuries caused to pedestrians, and for property damage.
Where to now? See you tomorrow at 9 AM!
