How geometry expresses the Second Law of Thermodynamics

Written by

A new thermodynamics approach based on a groundbreaking geometrical understanding of entropy.

Physicists have long struggled to explain how the inevitable increase in the universe’s entropy can be reconciled with the reversible laws of quantum mechanics. Now, Professor Chris Jeynes at the University of Surrey Ion Beam Centre, UK, believes he has found a solution in geometry. This new geometrical thermodynamics shows how the stability in time of structures as diverse as […]

Unifying quantum mechanics with Einstein’s general relativity

Prof Dr Norma Sanchez’s theory unifies quantum mechanics with Einstein’s general relativity, potentially transforming how we see the universe

The quantum nature of gravity is an enigma which has eluded even the brightest of physicists for many decades. Now, Dr Norma G. Sanchez at the French CNRS LERMA Observatory of Paris-PSL Sorbonne Université describes a possible solution. Her approach takes the form of a general theory, incorporating both quantum mechanics and Einstein’s theory of general relativity. If correct, her […]

Canonical quantisation: A solution to quantum gravity?

Written by

General Relativity and Quantum Mechanics are some of the most significant results in modern physics. Both theories appear to work seamlessly by themselves and have stood up to decades of scrutiny, but they also appear to be completely incompatible with each other. So far, no-one has managed to develop a theory which merges them together. Now, Dr Stuart Marongwe at the Botswana […]
