The Modular Optical Experimental Instruments (MOEI) are newly-designed laboratory demonstration tools which integrate a whole set of optical devices on single board. instructors can easily bring the MOEI to classrooms and demonstrate phenomena projector screens. In order investigate impact instruction double-slit experiment, we investigated 134 undergraduate students with an open-ended experime...

Public opinion polls consistently show that a growing majority of Americans support same-sex marriage. Critics, however, raise the possibility that these polls are plagued by social desirability bias, and thereby may overstate public support for gay and lesbian rights. We test this proposition using a list experiment embedded in the 2013 Cooperative Congressional Election Study. List experiment...

(and also the Einstein relation E = hν). How can the same “object” be thought of simultaneously as a wave and as a particle? According to the standard Born interpretation of the wave function, ψ(x), its square gives the probability per unit volume of finding the electron at point x. Suppose now that we want to describe in this way a particle known, with fair confidence, to be located somewhere ...

We present a method for determining the uncertainty in the measurement of parameters that describe the dynamics of a Foucault's pendulum. In the document, we review how these parameters can be obtained. Then, we propose a method for evaluating the uncertainty in their determination. We illustrate the method with experimentation made on a 28m height pendulum located at 20° 35' north latitude.
