摘要:

This is the first of a proposed series of columns presenting Physics Olympics “challenges,” activities that can be adapted as classroom laboratory experiments. The slow balloon race is based on Archimedes’ principle.

摘要:

What should an experimentalist do, arriving at a university with virtually no research equipment? Placed in this situation when I arrive here in 1958, I found water waves.

摘要:

We report the results of a longitudinal study of three nonmajor introductory classes that achieved relatively high FCI gains (g=1.5) using an inquiry-based tutorial approach. Original FCI gains persisted as many as four years following instruction.

摘要:

This demonstration is based on the familiar blind-spot phenomenon, except on a larger scale. I announce to the class that I will make one of them disappear and reappear right before their very eyes!

摘要:

Here is a brief analysis I like to show my physics students when we start rotational dynamics. It introduces the concepts of torque and rotational inertia in a somewhat natural way.

摘要:

In 1845 the Third Earl of Rosse built a telescope with a 6-ft metal mirror on his estate in Birr in Ireland. What was the largest telescope in the world until 1918 has recently been restored to working condition.

摘要:

We discuss two basic properties of angular displacements, namely, the anticommutation of finite rotations, and the commutation of infinitesimal rotations, and show how commutation is achieved as the angular displacement gets smaller and smaller.

This work provides a step-by-step guideline for the construction of a simple, low-cost generator of a nonpropagating hydrodynamic soliton.

摘要:

Newton’s second law is commonly misapplied to systems of multiple particles, as was done in a recent note inThe Physics Teacher. This note revisits the problem of a rope sliding in an L-shape tube.
