Research Associate, Stanford Linear Accelerator Center, Stanford, 1976-1978.” https://lnkd.in/e98wCbH5 View in LinkedIn

REMARKABLE COLLECTION. “We show that the concept of entropy and the dynamics of gravitation provide the linchpin in a unified scheme to understand the physics of black hole computers, spacetime foam, dark energy, dark matter and the phenomenon of turbulence.” https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

CONNECTED MATHS. “We use three different methods to estimate the foaminess of spacetime, which, in turn, provides a back-door way to derive the Bekenstein-Hawking formula for black hole entropy and the holographic principle.” https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

FINDING. “Generalizing the discussion for a static spacetime region to the cosmos, we find a component of dark energy (resembling an effective positive cosmological constant of the correct magnitude) in the current epoch of the universe.” https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

EMERGENT PHENOMENA. “The conjunction of entropy and gravitation is shown to give rise to a phenomenological model of dark matter, revealing the natural emergence, in galactic and cluster dynamics, of a critical acceleration parameter related to the cosmological constant; the resulting mass profiles are consistent with observations.” https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

CAUTION. “Unlike ordinary matter, the quanta of the dark sector are shown to obey infinite statistics.” https://www.mdpi.com/1099-4300/21/11/1035/htm View in LinkedIn

CLONAL ELMS. “As a genus they have given up sex, and the trees spread by putting out suckers. In normal circumstances this means that if elms are cut down (or blown up as they were in Flanders in the First World War) they re-grow from shoots below ground. By this means a stand of elms may live for many hundreds of years. But the elm’s dependency on cloning for renewal also makes them vulnerable to sickness.” https://lnkd.in/eSunuQVx View in LinkedIn
