Researches of a Teenager

Harshvardhan Sharma's "Researches of a Teenager" is a three-part book exploring fundamental physics and thermodynamics.The first part, "The Finitude of the Speed of Light," discusses how the finite speed of light is a foundational principle for causality, time, and cosmology. It covers the history of light theories, the contradictions of a hypothetical universe with infinite light speed, and experimental evidence supporting its finite nature. The author argues that without a finite speed of light, concepts like time and distance would be meaningless. The second part, "Limitations of Einstein's Formula (E=mc2), " examines the boundaries of this famous equation. It explains that while E=mc2 is valid for massive particles, it is not a universal law because it fails to account for the energy of massless particles like photons. The book highlights that the more general relativistic equation, E2=(mc2)2+(pc)2, and the principles of Quantum Field Theory (QFT) provide a more complete understanding of energy. The third part, "The Thermodynamics of Liquid Mixtures," moves into a practical analysis of mixing liquids. It starts with a derivation of the final temperature formula from the First Law of Thermodynamics. The book then discusses advanced factors that affect the final temperature in real-world scenarios, such as heat loss to the surroundings and the enthalpy of mixing.
