Fundamentals of Physics III ("Modern Physics")

PHY 2030 - An introduction to space-time physics and quantum physics with applications in astronomy, cosmology, solid-state physics, nuclear physics, and particle physics. Four credits. Prerequisite: PHY 2020. Offered Fall Semester.

Office Hours - M 3-4pm; T 11-12pm; W 9:30-10:30; Th 11-12pm; F 3-4pm; or by appointment (363 Couch Hall)

Useful Numbers to Memorize

  • Speed of light
  • Size of atom, nucleus (order of magnitude)
  • Diameter of Earth, Sun (order of magnitude)
  • Masses of protons, electrons, etc. (order of magnitude)
  • Common values that pop up in math (e.g., square root of 2 and 3, sine/cosine of 30,45,60 degrees)
  • Metric prefixes
  • Various unit conversions (both directions): km to miles, cm to inches, lbs in kg, etc.
  • Number of seconds in a year (~pi x 10^7)

SBG Assignment Rules

  • LReport - if you decide to write a full-blown report for a lab (to assess LReport), your lab report will be due TWO WEEKS after you conducted the experiment. I will take your highest assessment score into account at the end of the semester.
  • LApparatus - if you decide NOT to write a full-blown report for a lab (to assess LReport), you still must submit the results from your experiment; your results will be due ONE WEEK after the experiment. I will take the average assessment score into account at the end of the semester.
  • LJournal - you must submit your materials 1 WEEK after the LJournal assignment was given out. I will take only the highest individual assessment score into account at the end of the semester.
  • LFermi - I will assess you at random throughout the semester (in class). I will use the average assessment score for your course grade.
  • Other Standards - I will assess you approximately every 2-3 weeks (the 3 "exams" will be the major assessments). For each standard, I will take your most recent assessment score. (Note this means your assessment scores can go down even after you mastered them).
