Instructors

Professor: Tobias Marriage (marriage@pha.jhu.edu), Office: Bloomberg 215

TAs: Christopher Brust (cbrust@pha.jhu.edu), Sean Cantrell (seancan@pha.jhu.edu)

General Description

Welcome to the Advanced Physics Lab. In this class, you will carry out six experiments, some of which helped form the basis for modern physics. More importantly, you'll learn

• how to carry out an experiment with special attention to systematic effects
• how to analyze data from that experiment
• how to present your work through scientific writing.

These three aspects essentially define the course.

In this class you will complete six experiments. You'll do the experiments in groups of two or three. You will have two weeks to complete each lab.

Grading

Grades breakdown as 15% for each 2-week lab (75% report, 25% presentation), 5% for the initial lab, and 5% participation/effort.

Collaboration Policy

Execution of the experiment is a group effort, so is necessarily collaborative. Furthermore, students are encourage to discuss experiments, analysis, and other course related issues with their peers (and, of course, with the instructors). However, each person should carry out their own data analysis (e.g., no code sharing), produce their own plots, and write their own report. Violations of academic ethics (e.g., plagiarism) will be handled according to JHU policy. See http://www.jhu.edu/design/oliver/academic_manual/ethics.html.

Work Submission

We'll utilize Dropbox (www.dropbox.com) for submission of reports: each student will have a private dropbox by which to upload course materials for submission (and by which we can share files with you). If the dropbox fails, work may be emailed in PDF format to the instructor at marriage@pha.jhu.edu.

The reports are due by midnight on the day before the "submitted" date in the schedule above. Each student is allowed one late report, which may be up to one week late.

Recommended Texts

• Bevington & Robinson, Data Reduction and Error Analysis for the Physical Sciences
• Press, Teukolsky, Vetterling, Flannery, Numerical Recipes in C (Available online)
• Lamport, LaTeX: A Document Preparation System

Lab Reports

Lab reports constitute the backbone of the course. The reports are to be created on a computer with computer generated graphics, plots, etc. The document preparation system for the reports is LaTeX. The computers in the PUC lab have various installations of LaTeX editors/compilers. You can also download freeware for your personal computers. The lab reports should have an abstract, an introduction, description of the experiment (apparatus and procedure), description of the analysis, discussion of results, a conclusion (including future directions), and a bibliography. Lab reports will be collected on even weeks (See schedule.).

The course is fast paced and you'll want to stay ahead of schedule. You should begin writing your lab report in the first week of the class. You should plan to have the introduction finished by the end of the first week together with first drafts of all figures. A standard strategy is to create your figures first in order to guide the body of the text.
