Plan Your College Career!

• It takes 126 hours to graduate– 126/8 = 15.75 hours a semester to graduate

in 4 years– How many hours are you taking?

• What courses will you take? When will you take those courses?

• Have a plan (it may change) or you could easily stay in college longer than you think

The Multidisciplinary Nature of Computer Science

• Sometimes, CS may feel like a branch of mathematics (combinatorics, proofs of correctness, analysis of complexity...)

• However, CS becomes important to society when it is applied to real-world problems

Page 25: About the Major (CS at TAMU). Main Points Explain the rationale for the core course sequence/degree plan for majors. Establish expectations: be prepared.

• Information Technology is pervasive– computation, simulation, connectivity– meteorology, health care, construction,

mapping, oil industry, pharmaceuticals, communication, financial markets, entertainment, even the military

• More fields are becoming ‘data-centric’– digitization– amassing huge databases (petabytes)– many jobs in software industry focus on

processing/analyzing this data– “Data Science” - databases, search, machine

learning, statistics, pattern recognition

Page 26: About the Major (CS at TAMU). Main Points Explain the rationale for the core course sequence/degree plan for majors. Establish expectations: be prepared.

• Each application area has its own lingo– domain concepts, like anatomy/physiology...– types of data, format, sources of error

• Software engineers must learn how to communicate with customers– to understand users’ needs in that field– This is why we encourage you to develop an

orthogonal interest in a “supporting area”

• Since users don’t understand what things are possible/impossible with computers, we have to help guide the design– if we don’t use and understand their terminology, they

won’t respect us, and nothing gets done

Page 27: About the Major (CS at TAMU). Main Points Explain the rationale for the core course sequence/degree plan for majors. Establish expectations: be prepared.

• More application areas:– business processes, quantitative trading– music – MIDI format, synthetic music, sound

synthesis, filtering– biology – genomes, metabolic pathways,

protein interactions, regulatory networks– archeology – cataloging of artifacts,

searching, imaging, reconstruction– automobile design – engine controllers for fuel

efficiency/power, heat, emissions, manufacturing

– aerospace engineering - fluid dynamics and airfoil design, air-traffic control (congestion, routing), automation and displays in cockpit

your interest is your own, but thinkabout how it involves computation...

Page 28: About the Major (CS at TAMU). Main Points Explain the rationale for the core course sequence/degree plan for majors. Establish expectations: be prepared.

• Another example: Interface Design (GUIs) and Cognitive Science – in order to design good interfaces, it helps to

understand how people think– how do they respond to different visual inputs?

e.g. button size, color, placement– should have a “cognitive model” of what tasks

they might be doing and what questions they might have

– cognitive factors that impact software usage: • attention, interference between perceptual modalities• limits on short-term memory• consistency – e.g. meaning of buttons like “submit”

and “cancel”• fatigue, distraction, expectation biases...

Summary• The course sequence focuses on learning data

structures and algorithms at the lower level (along with systems and programming)

• Based on this foundation, you can take many upper-level electives.

• Be prepared for the rigor required in this major. Many topics in CS require mathematics.

• Computer science is inherently multidisciplinary, and it is important to learn the concepts and terminology in an application area.
