Crystal Ball: On the Future High Energy Colliders
High energy particle colliders have been in the forefront of particle physics
for more than three decades. At present the near term US, European and
international strategies of the particle physics community are centered on full
exploitation of the physics potential of the Large Hadron Collider (LHC)
through its high-luminosity upgrade (HL-LHC). A number of next generation
collider facilities have been proposed and are currently under consideration
for the medium- and far-future of the accelerator-based high energy physics. In
this paper we offer a uniform approach to evaluation of various accelerators
based on the feasibility of their energy reach, performance reach and cost
range. We briefly review such post-LHC options as linear e+e- colliders in
Japan (ILC) or at CERN (CLIC), muon collider, and circular lepton or hadron
colliders in China (CepC/SppC) and Europe (FCC). We conclude with a look into
ultimate energy reach accelerators based on plasmas and crystals, and some
perspectives for the far future of accelerator-based particle physics.Comment: 8 pp. The European Physical Society Conference on High Energy

On Soft Mathematical Models of Subjective Time Acceleration with Age
It is a commonplace perception that speed of time subjectively experienced by
humans significantly differs from chronological (objective) time and shows a
great deal of variability. An often cited example is the phenomenon of the time
acceleration with age - subjectively, the time passes faster as we get older.
While the exact mechanisms behind it are not yet fully established, here we
consider three 'soft' (conceptual) mathematical models that might be applicable
to the speeding time phenomenon: two proportionality theories widely discussed
in the past and the original model that takes into account the novelty of
experience effect. The latter is found the most plausible, as not only it
satisfactorily describes the decadal subjective time acceleration, but also
offers a reasonable explanation of the human life experience accumulation with
age.Comment: To be published in Nonlinear Dynamics, Psychology, and Life Science
