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 and Fox (1953) measured 385-MeV protons moving at ∼0.7c. Determination of the angular frequencies and of the magnetic field provided the charge-to-mass ratio. This, together with measuring the magnetic center, allowed to confirm the relativistic expression for the charge-to-mass ratio with a precision of ∼0.0006. However, Zrelov "et al." (1958) criticized the scant information given by Grove and Fox, emphasizing the difficulty of such measurements due to the complex motion of the protons. Therefore, they conducted a more extensive measurement, in which protons of 660 MeV with mean velocity of 0.8112c were employed. The proton's momentum was measured using a
