Understanding neutrino mass, Dark Matter and Supersymmetry are some of the issues beyond Standard Model. But the main loop hole is gravity which has been left out of Standard Model. The energy scale of quantum gravity, known as the Planck scale, is 16 orders of magnitude higher than the presently accessible TeV energies. So there is a long way to go.

Consider the following problems: Why cannot we distinguish between x and z ensembles, each described by the same density matrix, even though they are physically different (arXiv:1811.05472 [quant-ph])? Why do Gibbs-von Neumann entropy (which uses density matrix description) gives wrong prediction in closed non-equilibrium systems (arXiv:1903.11870 [cond-mat.stat-mech])? etc. Root cause of all these problems is the a priori assumption of existence of a probability measure (a purely mathematical quantity unjustifiable physically), on which density matrix description rests. But such a probability measure does not exist physically because of no pointwise convergence of limiting relative frequency to the theoretically assumed constant value for the probability of a random event. Hence such an a priori assumption of a probability measure (even though appealing intuitively) is incorrect physically. Moreover such an a priori assumption of a probability measure is not really necessary, even though useful for many practical purposes as it simplifies the calculations. Hence Ockham's thesis motivates us to drop the a priori assumption of a probability measure completely. We consider path by path, everything is pointwise (e.g., fluctuation in itself i.e., the actual fluctuation), no a priori probabilistic measures (like standard deviation which is an averaged measure of fluctuation) (arXiv: 1903.12096 [quant-ph]). Consequently we see that all problems are fixed i.e., we can distinguish between x and z ensembles (this leads to signaling via entangled particles), Boltzmann entropy gives correct prediction etc. I will also talk briefly about, going beyond Tsirelson bound and quantum cryptography; NMR investigation of contextuality, Luders and von Neumann measuring devices, and amplification of quantum Fisher information via pre-correlated ancillas.

Many important discoveries have been made in the field of neutrinos in the last 20 years and more are expected. The story of the discovery of neutrino mass through neutrino oscillations will be described. Experiments on solar neutrinos and atmospheric neutrinos which made this discovery were awarded Nobel Prize in 2002 and 2015. A mega project called India-based Neutrino Observatory(INO) is planned to come up in Tamil Nadu. The project and its present status will be described.
