3. FAQ

3.1. As a neuroscience major, what can I learn from this course?

First off, allow me to quote from Archimedes "Give me a lever long enough and a fulcrum on which to place it, and I shall move the world."

Through this course, we strive to provide a computational lever for you. With competencies in each major, I hope you eventually will be able to solve science problems such as:

  • Neuronscience: Understanding the visual cortex of the brain [1].
  • Biology: Solving problems of protein folding and structure [2]
  • Chemistry: Designing molecules [3]
  • Earth Science: Studying solid earth dynamics [4]

3.2. Exactly what kind of problems will I be able to solve?

To get a taste of it, here are two examples students worked on later in the last semester Tumor | Antialias.

3.3. Am I qualified for this course?

If you are concerned with math, most likely you are qualified for this course, provided that you understand

  • Trigonometry and Transcendental Functions
  • Some mathematical concepts to simplify science problems

3.4. How much programming is needed?

There is no requirement on programming languages.

In this course, a high-level computing language Matlab will be taught. Matlab is a powerful mathematical tool that offers a computing environment for numerical computation, graphics and visualization.

Students may access and use MATLAB without charge either on campus or from any computer with an internet connection. There are three ways to use Matlab at Mason:

  1. Via access to the virtual computing lab at Mason
  2. Matlab is installed on all computers in various computer labs on campus. Simply log on, and there is Matlab.
  3. Install Matlab on your personal computer. A $109-dollar student version of MATLAB may be purchased at Patriot Computers.

Tutorials on accessing and using Matlab will be given to students as class progresses.

3.5. What if I have a question about homeworks and am having difficulty understanding the course content?

  • My office hours will be held following each class or by appointment (hsheng@gmu.edu). My office is located in Research I, Room 370.
  • The T.A. of this course is Dr. Joseph Marr (jmarr2@gmu.edu). Dr. Marr will grade your homeworks and exams, and answer questions as well. While Dr. Marr can be reached by email and text or by a 'rolling' appointment, he prefers personal interaction with students. Usually he will be available after class and would like to interact with students using the whiteboard in Research I, Rm 302. Over the semester, several tutoring sections will be held to work on difficult problems.
  • Special announcements will be made through an email list, such as assignments, due dates, upcoming exams, tutorials, etc.
  • A group page has been set up on Facebook. If you have a Facebook page, welcome to join the group.

3.6. Do we have a textbook for this course?

None. The course "Computing for Scientists" was newly approved as a general education course at GMU. It has been co-developed by several faculty members at the CDS department. A wiki page (cds130.org) was created for this course in 2010 by Dr. Weigel. There are two sections (section 1 & section 2) in Spring 2011. All course materials covered in the current section can be obtained from http://cds130.org/2011S002.

The wiki page was designed to facilitate student interaction and to fulfill the IT requirements.

4. Syllabus

My syllabus is everything stated at Syllabus along with the following additions and notes.

4.1. Format

This is a three-credit course. Active learning techniques will be used during my lectures. After presenting a major concept I will pose a question which you will think about, discuss with your neighbor, and then possibly present your answers.

Be inquisitive and vocal during class.

4.2. Homeworks

  • Are 40% of your grade!
  • Weekly Homeworks. Assigned on Friday, due on next Friday before class
  • Will partially work many difficult problems in class
  • Most homeworks will be hand-written in the first half of the semester
  • Most homeworks will be turned in electronically in the second half of the semester
  • Late penalty = 20% if late by less than 7 days; 40% if more than 7 days late
