The problem of time's arrow arises due to the conflict between the time-reversal invariance of dynamical laws and temporal asymmetry of phenomena. In the late 19th century, Boltzmann proposed to avoid this conflict with speculative cosmological proposals, including the suggestion that the universe began in a low entropy initial state. Contemporary neo-Boltzmannians hold that this idea,...

Supposedly it is trivial to implement formal general covariance for any physical theory; just use tensor calculus. It is also widely believed, going back to Weyl in 1929, that spinors as such cannot exist in coordinates in curved space-time; one needs an orthonormal tetrad with 6 extra fields and extra local O(1,3) gauge group. These (incompatible) claims are both false. In 1965 Ogievetsky...

The Quantum Cinema 3D animated geometry depiction model is based on the idea that geometry must not remain restricted to the plane 2-D page but the invention of digital media makes the appropriate outlook of higher mathematics possible and animated 3-D graphics are the new medium for a new geometry which is introduced here. The basic discrete geometric model obeys the rules of the algebraic...
