I am a physicist and half a philosopher, that's why I feel totally lost and really confused.

The nature of #spacetime is still an open question in many ways. In this blog post, #StephenWolfram — who earned a PhD in #physics from #Caltech before moving into areas of computer science — discusses the evolution of his understanding of the concept of spacetime as a network and a project that he started some years ago and would like to return to.

I'm thinking deeply about the foundations of Relativistic Quantum Field Theory.
I master "Special Relativity", "Quantum" Is discussed for me but needs another and further research, "Theory" is well defined, now for the "Field" I'm studying "Wightman axioms".

Quantum dilemma: We have too many options for explaining reality
11 November 2015
IT’S time to put all the quantum cards on the table. That’s the view of a group of physicists who assembled in Vienna last month to present a variety of ideas, results and plans for future experiments that might help find an explanation for the weirdness of quantum theory.

The Holographic principle (Holographic universe and Quantum Hologram) is building a new perception of the world (it could be old but abandoned) destroying Materialism as a worldview. This needs more investigation and more data.

Trying so hard to complete an essay about "Nothingness" and that it's "Powerless", debunking Lawrence Krauss' claim that "Nothingness" is another form of "Being". Even though he didn't give arguments in favor of his claim in his book "A Universe From Nothing", I feel the urge to give a coherent set of rational arguments debunking his claim.

I'm a trained Physicist. I've started my PhD when I was 22. Truth and existential questions got me into philosophy first at the same age. Then a wanna-be philosopher mindset led me to question whether I do really understand the physics that I master. The surprise was: "Not at all". So I started being interested in the philosophy of science besides general philosophy and philosophy of religion.
I remember reading this article written by the philosopher of science and physics Tim Maudlin, and what remarkably caught my attention was the following paragraph:
"To the question as to why a physicist would want to hand time over to philosophers, the answer would be that physicists for almost a hundred years have been dissuaded from trying to think about fundamental questions. I think most physicists would quite rightly say "I don't have the tools to answer a question like 'what is time?' - I have the tools to solve a differential equation." The asking of fundamental physical questions is just not part of the training of a physicist anymore."

Can science truly prove anything?
#PhilosophyOfScience #Epistemology #PhilosophyOfPhysics #Science #ScientificMethod #Proof #Mathematics
#PhilosophyOfScience #Epistemology #PhilosophyOfPhysics #Science #ScientificMethod #Proof #Mathematics
“Proofs are mathematical entities: you start with a set of postulates, things that you begin with as givens. From those postulates, you take simple, straightforward steps, obeying the laws and rules of the system that you began with. As you progress, you can build up more and more complex rules, tease out intricate behavior, and axiomatically prove what will and won’t happen.
In science, at its best, the process is very similar, but with a caveat: you never know when your postulates, rules, or logical steps will suddenly cease to describe the Universe. You never know when your assumptions will suddenly become invalid. And you never know whether the rules you successfully applied for situations A, B, and C will successfully apply for situation D.”
Science gives us a great and powerful way to learn so much about the world. We can test things out, find a range of validity to our theories, make predictions and verify them, and increase our understanding of nature, the world, and the Universe, exactly as it is. We often say that science has “proven” a great many things — I say it too — but it isn’t true. All science can do is validate, confirm, and provide evidence that something is consistent with an idea or hypothesis being correct. But proof is another matter entirely, and something forever beyond what science is capable of. You can always prove that something is true given a framework and a set of rules, but you can never know when the rules you assumed will fail to apply to the situation you’ve newly encountered. However, don’t make the mistake of saying that just because there’s no such thing as scientific proof, we can’t know anything.
On the contrary, science is the greatest toolkit we have to gain actual, factual knowledge about the world we inhabit. While science can never prove anything, it can teach us more than, arguably, anything else. Read on to find out what it all means!

Mods: still not sure about the new categories - this public debate could be "outreach" but I chose "physical".
It's long but worth the view!

The Problem of Quantum Measurement
The measurement problem has been one of the hottest topics in physics ever since quantum theory was proposed and, despite much progress, remains so today.
Quantum mechanics is part deterministic, part probabilistic. According to the 'standard' quantum theory, states evolve with certainty between measurements, but 'collapse' randomly when we measure them. But what is measurement? And why does it (appear to) enjoy a privileged position in the theory?
The 1st Ockham Debate (13 May 2013) explores this topic in great detail, argued from 2 points of view:
•Simon Saunders [Professor of Philosophy of Physics and Fellow of Linacre College, Oxford] is a leading proponent of the 'many worlds' interpretation of quantum mechanics, which argues that the Universe we see is emergent, and constantly subject to 'splitting' - including during measurements.
• James Binney FRS [Professor of Physics, Director of the Rudolf Peierls Center for Theoretical Physics, and Fellow of Merton College, Oxford] advocates an alternative program, suggesting that we should gain insight into measurement by better understanding the dynamics of the system's interactions with the measuring apparatus.
