Formulas & Theorems Covered Today:
Lab and tutorial roomshave been changed - all first year labs are now in DV1110.Gideon's office is now in
DV1106L.Lab reports are now done collectivelyas a group.
PHY137will focus mostly on electricityand magnetism, as well as light and modern physics (the special theory of
relativity will be covered). This is chapters 17-21,24, and 27 in the textbook.
The history of the study of electromagnetism:
• 1600s:Gilbert names the force Electricus
• 1700s:Benjamin Franklin discovers electricity
• 1800s:Laming, Weber, and Faraday's contributions as well as
○ 1891:George Stony coins the term electron from the Greek word for amber and ion for the portion
of the atom which gave it its charge
○ 1897:Thompson discoversthe electron
• 1923:Milikan finds for atomsthrough the oil shop experiment, which eventually leads to finding the
Charges can be negative or positive.
• The elementarycharge is the electron, where
○ q represents the magnitude of the charge
○ N represents the number of electrons added or removed
○ e represents the electroniccha
