Fundamentally – What do I know?

Fundamentally – What do I know? Black holes ain’t so black, and science ain’t so different from the humanities. Singularities have horizons crammed with information. Nothing objective is more fundamental than the information available. This is a summary of recent work ostensibly on quantum gravity and the role of humans more generally in the science … Continue reading “Fundamentally – What do I know?”

Emergence from Quantum Information

The early version of this Edward Witten interview by Natalie Wolchover – since corrected – was criticised for suggesting his M-Theory was the only current model (with any worthwhile credibility) attempting to unify quantum and gravity fields. His idea of (M-em)branes combining multiple string theories in multiple dimensions beyond 3 is now 22 years old. What … Continue reading “Emergence from Quantum Information”

Why Fluid Dynamics is not boring?

A bookmarking post only. Interesting to me as an one-time fluid-dynamicist, and I’ve mentioned the parallels before between Navier-Stokes et al in Fluid Dynamics and more fundamental physics. Especially point-based (Boscovich), quantum-loop-based (Rovelli) and integrated-information (IIT). Just capturing the link here. “fluid dynamics, is surprisingly pivotal to understanding some of the most elementary constituents and … Continue reading “Why Fluid Dynamics is not boring?”

Carlo Rovelli – A Fresh Spin on Fundamental Physics

Interesting to see today’s news on standardisation of units of measure, that time, distance and mass are now to be unified through the Caesium clock with application of the speed of light (c) and Planck’s constant (h). (Hat tip to Jim Al-Khalili on Twitter). Fascinating article in itself, however yet more evidence that the accepted standard … Continue reading “Carlo Rovelli – A Fresh Spin on Fundamental Physics”

Proud to be an Aero Engineer

It’s a long time since I qualified as an Aeronautical Engineer and worked on Tornadoes, Hawks and Harriers, and I’m still a sucker for plane-spotting – civil or military. At a time when civil aircraft are all increasingly scale-efficient clones of each other, and air-travel a non-PC chore, driven by eco-econo-geo-political considerations, it’s a wow to … Continue reading “Proud to be an Aero Engineer”
