PhET Interactive Simulations is part of the University of Colorado Boulder which is a member of the Association of American Universities. [10] The team changes over time and has about 16 members consisting of professors, post-doctoral students, researchers, education specialists, software engineers (sometimes contractors), educators, and administrative assistants.

Perkins was named as a Fellow of the American Physical Society, in the 2021 class of fellows, "for profound contributions to physics education through the vision and leadership of the PhET project, resulting in the creation of many high-quality interactive simulations for teaching physics to hundreds of millions of students and teachers globally".

Apart from textbooks, instructional material for pre-college physics students now include PhET (Physics Education Technology) simulations. This is made possible through advances in personal computer hardware, platform-independent software such as Adobe Flash Player and Java , and more recently HTML5 , [ 11 ] CSS3 and JavaScript . [ 12 ]
In quantum mechanics, the probability current (sometimes called probability flux) is a mathematical quantity describing the flow of probability. Specifically, if one thinks of probability as a heterogeneous fluid, then the probability current is the rate of flow of this fluid.
In this case, the voltage refers to the voltage across a biological membrane, a membrane potential, and the current is the flow of charged ions through channels in this membrane. The current is determined by the conductances of these channels. In the case of ionic current across biological membranes, currents are measured from inside to outside.
Then M does not admit a Kähler structure if and only if M admits a non-zero positive (1,1)-current which is a (1,1)-part of an exact 2-current. Note that the de Rham differential maps 3-currents to 2-currents, hence Θ {\displaystyle \Theta } is a differential of a 3-current; if Θ {\displaystyle \Theta } is a current of integration of a ...
In that case, the barrier is due to the gap between the tip of the STM and the underlying object. Since the tunnel current depends exponentially on the barrier width, this device is extremely sensitive to height variations on the examined sample. The above model is one-dimensional, while space is three-dimensional.
