What, Why & How do we Know ?
Two things came together this morning. Firstly, over the weekend I engaged in a Facebook thread by Sabine Hossenfelder discussing Brian Keating’s brief video: “What’s a Greater Leap of Faith, God or the Multiverse?”. And secondly, this morning I listened to Elizabeth Oldfield in conversation with Tom Chivers in Theos’ “Sacred Podcast”. Brian’s conclusion in … Continue reading “Is Truth Sacred?”
This is just a holding post. Already in my previous post on Carlo Rovelli, I was overdue a fuller review. Since then I’ve been reading Sean Carroll, and finding myself reading backwards, from the index of key topics and chapter headings. The reality is that every current philosophical physicist I read, I find enormous implicit … Continue reading “The Matrix Cometh”
I’m reading my way through Carlo Rovelli’s “The Order of Time” (Finished Part 1 of 3) and finding it full of items that resonate. Not least because I already loved his “Reality is Not What it Seems” but also because I have been joining up the dots with the work of David Deutsch and Erik … Continue reading “Well we never! PoPoMo Physics Again.”
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?”
So many intellectual inputs and opportunities for dialogue of which barely a tenth can be grasped over a weekend at Hay on Wye, at the How the Light Gets In HTLGI 2018 Festival. [Meta – specific sessions and update on the weekend experience here.] Below is my summary of the messages I heard in the … Continue reading “Are We Nearly There Yet? #htlgi18 #htlgi2018”
Compiling my Hay-on-Wye 2018 How The Light Gets In report, starting with the meta stuff below, content report is here. Mid-day Friday to Mid-day Sunday this year. My third time. Last year being a fallow year for the event. Previous year weather was excellent, combined the event with some days walking in the Brecon Beacons … Continue reading “#HTLGI2018 Update Meta”
I’ve been interacting with Jaap van Till for the last year or two, mainly on Twitter. His blog is The Connectivist. He recently made a reference to, and separately blogged about, Ann-Marie Slaughter’s “The Chess Board and the Web“ in a comment to me. And my response was to liken the sound of her “Chessboard” … Continue reading “The Connectivist”
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”
