An Introduction to Error Analysis, Second Edition, by John R. Taylor

Although you can survive the semester without it, this is such an important topic, and the book is inexpensive enough, that I strongly urge you to order it directly from the publisher (they give a 15% discount). This book will be a good reference throughout your scientific career. Click HERE for a web link, and order your copy.

Brief Overview

 Physics 240 (and the second semester option phy242) is the Physics   Department's Intermediate Physics Laboratory. It is currently the only course where undergraduates get experience with more advanced experimental techniques, serious error analysis, and are able to perform experiments to measure fundamental physical properties. You will also get to make mistakes in lab, and have to the time to fix them, just like a real working laboratory. 


In addition to performing the experiments, students will maintain a laboratory notebook, learn how to use LaTEX to professionally typeset your reports, and how to give 10 minute oral presentations of their work. 

Working in groups of 2 (or perhaps 3) on each experiment over the course of the semester, students will perform 4-5 laboratory experiments. This course is excellent preparation for graduate school and presenting at research conferences.

Drawing Figures 

There are many ways to draw figures for inclusion in a LaTeX document; they can be drawn in a  dedicated drawing program like Illustrator (big $!) or InkScape:

Inkscape a free cross-platform vector graphics program which I highly recommend; has the ability to plot algebraic curves and include LaTeX expressions. I prefer it to Adobe Illustrator for these reasons (not to mention that it is free) 

Or, you can draw figures in a programmable environment for direct inclusion into LaTeX files; there are two options I’m exploring right now: 

Asymptote (A vector based drawing language) 

or

Pgf/TikZ 

You can see examples of Pgf/TikZ figures at TeXample

Scientific Graphics

Igor Pro: An excellent data analysis package for which the Physics Department has a course use license (i.e. free for you to use in this class - Mac/PC only)  Wavemetrics Home Page

Other Options (open source):

Python: more and more I find myself using python/matplotlib to analyze data. Especially with the advent of the iPythonNotebook format.

QTiPlot (sort of open source; author would like a donation---but it's free on the Linux platform)

Veusz (pronounced "views") - totally open source

Gnuplot - command line tool for making plots.

Presentations

There are two main tools people use for presentations: (1) Powerpoint (PC/MAC) or Keynote (MAC) or OpenOffice (PC/MAC/LINUX) and (2) LaTeX. One of the items you’ll need to do for both is include figures and equations. Figures are easy to include in each, and in LaTeX, equations are also simple. Not so for Powerpoint; in fact, for the first option (Powerpoint, Keynote, OpenOffice) equations are best added using a LaTeX aware program to typeset equations; see this page at MIT’s junior lab for more info: Link

LaTeX: There are several packages for presentations in LaTeX, Beamer being one of the more popular. Here are some links that you may find helpful: (the first link is a shamelessly modified version of the MIT junior Lab template.)

If you’re using PowerPoint or Keynote or OpenOffice, the following applications will allow you to create pdf or png images of equations that are drag&drop ready:
