We cannot make the mystery go away by “explaining” how it works. We will just tell you how it works. In telling you how it works we have told you about the basic peculiarities of all quantum mechanics. … (color by Tachibana) cf. R.P. Feynman, R.B. Leighton, M.

SCOPE Chemical ideas restricted now to nonrelativistic quantum theory may be unified and extended in future to relativistic quantum field theory that is basic to Particle Physics and Cosmology; realization of the new generation quantum theory. In order to accelerate this new trend, we are organizing the topical symposium aiming at mutually stimulating the cutting edge of basic theoretical approaches of quantum theory. TOPICS Topics to be covered include, but not limited to, the cutting edge of basic theoretical approaches of quantum theory in particle physics, cosmology, and chemistry.

I would like to thank all the invited lecturers and participants! I would like to enjoy this symposium with you all! Thank you for your attention!
