Some of My Down-to-Earth Interests

• Computer simulation of a stretched string without any small oscillations approximation (Computers in Physics, 8, 446, (1994)).
•  Quirks of Quantum Mechanics (Electron Spin and Samuel Goudsmit: Chapter 6 of "Models and Modellers of Hydrogen" (1996, World Scientific)).
•  Eyeglass design for double vision correction (NIH funded project).
• Computer puzzle games and group theory (Computers in Physics, 12, 488, (1998)).
•  Quantum computer games
  • "Quantum Duck Hunt".
    • Here's a paper on the subject:- (Computing in Science and Engineering, 3, 84, (2001))
  • "Quantum Focus"..
    • Here's a paper on the subject:-(arXiv.org)
    • "Quantum Hide-and-Seek." Article by Kim Krieger (Science magazine)
    • "The Hunting of the Quark." Article about this game (Photonics Spectra magazine, July 2004.)
• Tae Kwon Do (black belt).

Some of My More Esoteric Interests

• Spiral Galaxy Rotation Curves.
  • Spiral Galaxy Rotation Curves Without Dark Matter or MOND -- Two Conjectures (2018)
• The Black Hole Controversy.
  • Freely Falling Finite Frames Near a Black Hole (2015).
  • "More on black holes and quantum information" Phys. Today 66, 11, 10 (2013).
  • Through the Black Hole -- On Not Breaking Time Reversal Symmetry (2010).
  • Physical Interpretation of Coordinates for the Schwarzschild Metric (2008).
  • Black Holes -- An Astronomical Myth (2003).
• Composite particle Quantum Electrodynamics -- Treating electrons and photons as composites can get rid of infinite renormalization and the problem of Haag's theorem without sacrificing experimentally observed effects like anomalous electron magnetic moment and Lamb shift. The following are a couple of papers on the subject.
  • Nonunitary Interaction, Adiabatic Condition, Haag's Theorem and Renormalization (2008).
  • Quantum Field Theory without Infinite Renormalization (2005).
• Higgs mechanism for particle mass generation.
  • Another Alternative to the Higgs Mechanism (2009).
• A theory for strong interactions (alternative to Quantum Chromodynamics?) with first quantized quarks but second quantized composites of quarks (hadrons) (Nuovo Cimento A, 107, 863, (1994); Nuovo Cimento A,104, 995, (1991)).
•  A special relativistic extension of the Newtonian theory of gravity that explains all unambiguously observed experimental results (red-shift,bending of light near a massive star, precession of planetary orbits and gravitational waves) (Foundations of Physics, 24, 513, (1994)).
•  Social behavior of the physics community and its effects on physics.
• Mathematical Logic in Everyday Life (The One Commandment)

Dredging up the past

I received a masters degree in Physics (Fiber Optics) from the Indian Institute of Technology at New Delhi in 1978. The same year I went to Syracuse University (New York) for further studies. There I did another MS in Physics (1979). I continued at Syracuse University until 1984 when I completed both a PhD in Physics and a MS in Computer Science. Since then I have been at SUNY at New Paltz.
