IAGRG30 – India’s Biennial Gravity Meetup I was recently in BITS Hyderabad 1 attending the 30th meeting of the Indian Association for General Relativity and Gravitation (IAGRG30). I was pleasantly surprised that my abstract was selected for a talk and that too for the very first talk on the first day of the “Quantum Gravity”… Continue reading IAGRG30 – Kepler, Maldacena, Ashtekar and all that …

# Thermal Time and Kepler’s Second Law

In a fascinating recent paper (arXiv:1302.0724), Haggard and Rovelli (HR) discuss the relationship between the concept of thermal time, the Tolman-Ehrenfest effect and the rate of dynamical evolution of a system – i.e., the number of distinguishable (orthogonal) states a given system transitions through in each unit of time. The last of these is also… Continue reading Thermal Time and Kepler’s Second Law
