PhET Interactive Simulations, a project at the University of Colorado Boulder, is a non-profit [1] open educational resource project that creates and hosts explorable explanations. It was founded in 2002 by Nobel Laureate Carl Wieman. PhET began with Wieman's vision to improve the way science is taught and learned.
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".
[4] [5] An emerging branch of Citizen Science are Community Mapping projects that utilize smartphone and tablet technology. For example, TurtleSAT [6] is a community mapping project that is mapping freshwater turtle deaths throughout Australia. This list of citizen science projects involves projects that engage all age groups.

Example of the integrated use of Modelling and Simulation in Defence life cycle management. The modelling and simulation in this image is represented in the center of the image with the three containers. [15] The figure shows how modelling and simulation is used as a central part of an integrated program in a defence capability development process.
The term "explorable explanation" was first used in passing by Peter Brusilovsky in a 1994 paper, [1] but did not enter into common use until 2011, when Bret Victor published an eponymous essay [2] (the essay included an explorable explanation of a digital filter). Victor distinguishes explorable explanations from isolated interactive widgets ...
The English term thought experiment was coined as a calque of Gedankenexperiment, and it first appeared in the 1897 English translation of one of Mach's papers. [11] Prior to its emergence, the activity of posing hypothetical questions that employed subjunctive reasoning had existed for a very long time for both scientists and philosophers.
The variance of the estimate X 1 of θ 1 is σ 2 if we use the first experiment. But if we use the second experiment, the variance of the estimate given above is σ 2 /8. Thus the second experiment gives us 8 times as much precision for the estimate of a single item, and estimates all items simultaneously, with the same precision.
