LOG#204. Mechanics and light.

Gravitational or electrical forces are inverse squared laws:         Strikingly similar, they are both also conservative forces. For gravity:     and     for the electrical force. Defining the potentials , and , you get the … Continue reading

LOG#077. Entropic electrogravity.

Tower Wang, in his paper Coulomb Force as an Entropic Force, deduced Coulomb and Newton laws using the Verlinde approach in D=3+1 dimensions. He begins with the Reissner-Nordstrom metric in D=4 spacetime: with the function and He introduces a “geometrized” … Continue reading

LOG#031. Entropic Gravity (II).

We will generalize the entropic gravity approach to include higher dimensions in this post. The keypoint from this theory of entropic gravity, according to Erik Verlinde, is that gravity does not exist as “fundamental” force and it is a derived … Continue reading

LOG#030. Entropic Gravity (I).

In 2010, Erik Verlinde made himself famous once again. Erik Verlinde is a theoretical physicist who has made some contributions to String Theory. In particular, the so-called Verlinde formula. However, this time was not apparently a contribution related to string … Continue reading
