This monograph has gathered together three extraordinary problems in theoretical physics to be solved exactly. The problems range from the long-standing limit problem of the simple harmonic oscillator in quantum mechanics, the unfolding of a hidden symmetry in the Markovian birth-and-death equations, to the four-hundred-year-old problem of the simple pendulum. Therefore, this monograph is a rare "three-of-a-kind" collection of major essays on seemingly unsolvable problems in physics.

The Chronicles of Dragondom and Beyond is the story of Aisha.

Yes, a girl. A shy human who from an early age always felt different. Then when she moved, renting her first home alone, in a little town nestled in an ancient stone circle, the magic began. She walked through a portal in time and space into a magical, mystical world of Arionel where trees talk, unicorns and magical creatures live, and yes, dragons.
