Creatorverse the tablet’s touch screen to create designs that could then be animated and set into motion using various physics-based properties and attributes (such as friction, speed and force). All creations can then be shared among other creators, who also have the capability to remix, expand or even dismantle other community creations. Inspiration for Creatorverse, including the logo, originated from the popular device Newton's cradle, which demonstrates conservation of momentum and energy via a series of swinging spheres. Creatorverse Creatorverse was a physics-based sandbox creation game for the Apple iOS, Android, Kindle Fire, and Kindle Fire HD that was released in
Tests of relativistic energy and momentum Litz wire, and the velocity was determined by evaluation of Cherenkov radiation. They confirmed relativity with an upper limit for deviations of ∼0.0041. Since the 1930s, relativity was needed in the construction of particle accelerators, and the precision measurements mentioned above clearly confirmed the theory as well. But those tests demonstrate the relativistic expressions in an indirect way, since many other effects have to be considered in order to evaluate the deflection curve, velocity, and momentum. So an experiment specifically aimed at demonstrating the relativistic effects in a very direct way was conducted by William Bertozzi (1962, 1964). He employed
