Modern Physics: An Introductory Survey

Misleading points in the teaching of Millikan’s experiment on the photoelectric effect

“…Today, almost half a century later, we find that not much has been done to correct this mistake. Some commonly used textbooks [7][8][9] still contain this same error, and it is likely that as a result, students in some high schools and universities are still misled unintentionally. The origin of this mistake comes from the knowledge that in an open circuit it does not matter where you choose to measure the potential difference between the two ends of the battery.…”

The Narrative Act: Wittgenstein and Narratology

“…They point up the existence of a principle of narrative uncertainty partly analogous to Heisenberg's Uncertainty Principle in physics. [8] The latter states that the precision of our measurement of a particle's momentum is inversely proportional to the precision of our measurement of that particle's position. The reason for this is that the measurement of a particle's momentum interferes with and alters the position of that particle -and vice versa.…”
