[Mathematics is] a very powerful and effective language invented by humans to describe and discover patterns in nature. When we perceive beauty in the mathematics, I think what we’re really perceiving is an underlying beauty in nature itself.
— Jim Baggott, Quantum Space
Lo spazio in questa stanza esiste indipendentemente dagli oggetti presenti in essa? Il tempo esiste indipendentemente dalle cose che vi accadono? In altre parole, lo spazio e il tempo sono di per se stessi «assoluti»?
Lo spazio non è qualcosa che percepiamo direttamente. Noi percepiamo gli oggetti (cose come i monitor, i libri e i divani-letto) i quali hanno, gli uni con gli altri, relazioni che chiamiamo «spaziali»: questo è qui alla mia sinistra, quell’altro è laggiù a destra. Ma, di per sé, lo spazio non è parte del contenuto della nostra esperienza diretta. Noi interpretiamo gli oggetti considerandoli esistenti in uno spazio tridimensionale a seguito di una sintesi di segnali elettrici all’interno del nostro cervello, segnali che poi la mente traduce in percezioni visive. In modo analogo, io mi muovo nel tempo (quanto meno, in una direzione) ma non posso vederlo e non posso protendermi a toccarlo: il tempo non è un oggetto tangibile. Il mio senso del tempo sembrerebbe scaturire dal mio senso del sé e dal fatto che gli oggetti che mi circondano modificano la loro posizione relativa (questo prima era a sinistra, adesso è a destra), oppure la loro natura, passando da un tipo di cosa a un altro
For the émigré philosopher Imre Lakatos, science degenerates unless it is theoretically and experimentally progressive
The problems with post-empirical science
The problems with post-empirical science
Jim Baggott has a pretty good piece at Aeon on the problems with post-empirical science. I’ve highlightedBaggott’s views before. Along with others like Sabine Hossenfelder and Peter Woit, he calls attention to a serious issue in physics, the rising acceptance of theories that show little promise of being testable in the foreseeable future. In many ways, this piece is a reaction to Sean…

Quantum Space: Loop Quantum Gravity and the Search for the Structure of Space, Time, and the Universe, by Jim Baggott
Synopsis: Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein’s general theory of relativity, which describes the large-scale behaviour of matter in a curved spacetime. This theory is the basis for the standard model of big…

How does 'Matter' exist
How does ‘Matter’ exist
The following talk by Jim baggott presented at The Royal Institute gives you a brief knowledge and understanding of the most basic thing around us, something that passes and is our part of life that ultimately results in everything around us. Matter.
Jim baggott is a British writer living in England at present who writes about science, philosophy and science history. Some of his books like Farewe…

Mass
Everything around us is made of ‘stuff’, from planets, to books, to our own bodies. Whatever it is, we call it matter or material substance. It is solid; it has mass. But what is matter, exactly? We are taught in school that matter is not continuous, but discrete. As a few of the philosophers of ancient Greece once speculated, nearly two and a half thousand years ago, matter comes in ‘lumps’, and…
