So much respect and appreciation to Dr. Wallace and all his accomplishments in the Philosophy of Physics. Such a delight to listen in.
A very engaging conversation. I like David's way of presenting his views and thoughts.
First! Awesome video. Great discussion
Philosophies regarding what can be known, including issues relating to measurement and observation, and what knowing _is,_ have a place as a meta discussion around science, and can also provide a platform to engage in exploration of knotty and unsolved areas.
sandra that is very importnat i did remember that tonight
I think we should definitely teach philosophy of physics and philosophy of science to physics students.
*If I live in an earthquake prone area, I sure would want a structural/civil engineer with solid knowledge of physics to show me what structures we can build (and how) to withstand a 7.2 earthquake; this will likely ensure our survival. I don't need a myth specialist or a "philosopher" to tell me about people's suffering after the earthquakes strikes and kills people.*
@@PhuckYourExistenceThe birth of physics, Aristotle. The philosopher. Every subject of human knowledge is intertwined with philosophy.
@Absurd-Woman We humans are first of all intelligent beings. Therefore, knowledge, including physics, is not only a means of our physical survival but first that of the intellectual survival - a means of the happiness of intelligent beings - an intellectual pleasure. Your reply reveals the common problem that schools do not teach physics in an intellectually interesting way.
@@user-xn4wq4sv3r This is the third comment I have seen from her. How in the world does she think science can exist without logic or epistemology? Two fundamental principles of philosophy.
@@hephaestusfortarier249 please explain that to these indoctrinated scientism individuals.
If the gravitational field is spacetime then we live in a multiverse! I live in a universe and so do you but, they're two different universes and they sum together with the rest.
Very well said.
i was schizophrenic from tics it timed perfect with turtles
Quantum information is fundamental underlying...
Quantum Mind emerge, Quantum Body emerge,
Mind and Body entanglement.. Consciousness emerge.
Spacetime emerge,
Holographic principal.
Philosophy is just mind game. Web of thoughts.
It’s the love of wisdom.
@@hephaestusfortarier249 Love may take us more CLOSER TO TRUTH, wisdom... But philosophy is absolute modern day mind game. It is dangerous and will only lead us in to more confusion. Philosophy is the child of present day head oriented education. It's a disaster for humanity.
@@sujok-acupuncture9246 The word means love of wisdom, and those who don’t love wisdom, love folly. Be wise or a fool, you’re choice. Edit: Didn’t realize you’re a child. Sorry.
I think physicists could use a bit more imagination when contemplating their hard questions. philosophers can offer some imaginative constructs via their distinct pov - esp on highly speculative topics. their ignorance of the latest deep knowledge in physics is not a drawback, but a feature that yields a novel approach for physicists. there's value in sharing alternative constructs of reality among adjacent fields - if only as a catalyst when one is stuck... even if only a secondary or tertiary consequence of arguing in bars.
then, there's the timeless urge for a unified model of all reality. while its truth must be confirmed through scientific means, that truth could conceivably be derived through any field of knowledge.
> their ignorance of the latest deep knowledge in physics is not a drawback, but a feature that yields a novel approach for physicists
What he's talking about is when philosophers say X, Y or Z will never be observed, but it turns out physicists observed X Y and Z to 5 Sigma confidence 50 years earlier, and the result has been verified using 3 different experiments since. That sort of thing happens a _lot_ with quantum mechanics.
thx. my point is creativity that aids in unraveling tough, fundamental issues in science may be sourced wherever dedicated, smart people think long & deeply... just as from dreams. novel scientific theory might even emanate from unusual sources... like philosophers. @@simonhibbs887
Why can't physics and philosophy and dare I say even a touch of religion, all work hand in hand to try and work out what ultimate reality is and what the hell we're doing here??? I don't think any one discipline can provide the answers on its own but combined could be a force to be reckoned with?
Because religion is zero sum with reality
*"I don't think any one discipline can provide the answers on its own but combined could be a force to be reckoned with?"*
... You are absolutely correct! That's exactly what I did in my book. No single data processing method can reveal the ultimate reality. It requires all data processing methods and ideologies. We don't get to "pick and choose" how reality unfolds.
*Religious nuts tried Galileo for heresy. Religion and fairy tale specialists tried to impede Copernicus' work. I can go on an on. Religion/myths/belief in "gawd" are nothing but impediments -- surely responsible for the deaths of millions throughout history. Religion is a form of cancer. Pls, do not offend us!*
A is 3 as so are we and 0 is 2 for i am not you
An interesting nuance of science is that it can only provide "after the fact" observations. QM can tell you how many quarks are in a proton and how they are configured but can't tell you where they came from, how they got here, and why they exist in the first place.
... This is where philosophy steps in! Philosophy takes what science hands it and helps to paint the entre picture.
Even though science needs philosophy to delve into the reasoning behind everything it observes, and philosophy needs science to accurately describe the substance used behind its reasoning, both ideologies end up pointing their epistemological fingers at each other while shouting, *_"Take a look at the guy!"_*
As you CORRECTLY point out, Qm can not tell us where particles come from OR why they exist, but arguably, the most precise theory ever developed called QFT can potentially account for that.... Peace brother.
@@Bill..N *"but arguably the most precise theory ever developed called QFT, certainly does."*
... All of these complex theories have their strong points and weak points, and I'm not marginalizing any of them (except for Multiverse).
QFT explains the existence of particles like gumballs in a vending machine. Just pull a lever on the machine and out pops a gumball. And should you ask where the gumballs inside the machine come from, QFT answers with, _"Well, ... from that thar machine!"_ ... To me, that's not a satisfactory answer.
The answer is time. Time is not emergent time is the reason things can emerge. Time is energy. Matter needs energy to emerge. What you are speaking on is pseudoscience. Real science is humans. Observing nature and nature has already provided all the answers. Some humans are still searching for the answers. However, the answer is constantly Present. Time. We experience time through our star the sun. For example, the periodic table. No star no oxygen. No oxygen, no consciousness. Think before you ask the redundant question of where did time come from. Research each word in that redundant question. You will find time in every word. Read more non-fiction. What is your age? No star no growth. What are you breathing? No star no oxygen. Read more nonfiction. Dictionary. Encyclopedia. Thesaurus.
Science, rebukes philosophy. Philosophy is based on mythology human imagination. Wisdom of Sophia. Sophia is a mythological character from Greek mythology. Fiction. Physics is a science where humans observe nature. The answers are already present in time. For example, time equals energy and energy equals mass times the speed of light squared, no space. Space is human imagination based on science fiction. Read more nonfiction. Dictionary. Encyclopedia. Thesaurus.
@0-by-1_Publishing_LLC As you might know by NOW friend, we disagree on many but not ALL things, which is fine... I know you are a smart guy, so I'm confident you understand that QFT makes INCREDIBLY accurate predictions to at least twelve decimal points! A much higher predictive accuracy rate than let's say (as an intuitive example), ACCURATELY predicting the day you will die AND to within MUCH less than a single second.. Still think it's not a reliable indicator suggesting an actual reflection of reality?
I find it difficult to take seriously anyone who begins by saying, "I mean..".
Philosophy is the softer side of Science. Both are fundamental. One is limited and the other is unlimited.
Philosophy takes precedence over Science. There's different philosophies of Science that scientists don't exactly agree on.
@@Resmith18SR Yeah... I forgot philosophy gave us hundreds of vaccines for so many illnesses. I also forgot that philosophy got us to the moon, GPS, lasers, modern medical equipment, penicillin, the modular structure of DNA, etc. 🤡🤡🤣🤣
@@PhuckYourExistenceDoes bro realize what a PhD even is?
@@PhuckYourExistence You don't realize that Philosophy is more comprehensive than Science and every scientist is well aware of that. Don't talk nonsense. Philosophy isn't Science and doesn't pretend to be about going to the moon, or discovering the molecular structure of DNA or penicillin. Philosophers like Bertrand Russell, Alfred North Whitehead, Kant, Schopenhauer, didn't have the goal of giving the world modern medical equipment or vaccines.
@@PhuckYourExistence You do know science is derived from philosophy, right? Because once upon a time, science was a branch of philosophy called natural philosophy? And please explain how can science exist without epistemology, with the presuppositions and goals of any scientific paradigm to have taken place? So, like it or not, science and philosophy are interwoven in some degree .
If i were a professional philosopher, I'd definitely affect a fake Brit accent.😂
& German for the physicists?
like someone nasa old blood old human best worker yet you R Concerned thank you
"[Many Worlds Interpretation] - demands an explanation of when, where, and how it is decided what the observer actually records."
~Zurek #p5 #2002 #QuantumPhysics #Science
The measurement problem, the Born rule. It actually also is a problem in Kopenhagen interpretation, yet just Deus ex machina inserted as a collapse, which seems like a non-physical thing or process. So no less magical
@@Robinson8491 Yet, how many Many-Worlders admit it still remains a problem?
It's not just MWI that demands an explanation to measurement/observer, so do all the interpretations. With decoherence you still end up a number of 'smeared out' quasi-classical possibilities that "demands an explanation of when, where, and how it is decided what the observer actually records"
@@johnyharris Yes. But MWI believers often appear to think MWI removes the observer/measurement problem. It doesn't. In fact, it adds quite an astonishing embellishment if true (and for all we know, it could be true).
Time is emergent? I think a photon would agree.
sandra and kelsey i cold blood murdered you because you both killed me forevor?
Who pays his salary and can I do that too? Blah blah blah, collect paycheck
Physics is inherently meaningless, as it can proceed without regard to which interpretations are followed, yet interpretation is what gives us meaning. How strange that we are only now realizing that Consciousness is a fundamental anomaly in physics, as none of the laws of physics require or imply its existence. Next, Synchronicity.
I can not carry on like this and I need to change my life. I am a psychologist and I have discovered atheism is a logical fallacy that assumes God is the religious idea of the creator of the creation to conclude wrongly no creator exists because a particular idea of God doesn’t exist. I need to rest and above all I need to be understood. I offer for free my knowledge to you. Are you interested in a new concept of God with a perfect eternal hell and heaven?
Nope. I don’t believe a word you said.
@@KestyJoe Nothing of what i say is "spam", even lies are interesting. I am a poet that writes prose to be understood better, all my work is poetry. I am God and humanity have to act swiftly and efficiently to avoid deaths. From now on all the executions in the world are cancelled to save lives. Who would disagree with that? Humanity would have a debate and referendum on the abolition of the death penalty. In my curriculum I have that I was religious and atheist and I have discovered that the greatest knowledge of all time, that is going unnoticed, censored and not understood, is atheism is a logical fallacy that assumes God is the religious idea of the creator of the creation to conclude wrongly no creator exists because a particular idea of God doesn’t exist. Would you do me a favor and tell your innocent and vulnerable children what i just told you? They would understand what humanity don't.
Philosophy = pub conversation
Guys are absolutetly wrong. He mistakes shows philosophy are dark side of phich . Big mistakes guys. Descartes show up though reason it describes phich proceendings. Guys read Descartes that modern phich began. You mind are living in others worlds when philosophy of science you mealing.
You should check your wording better
Kindly repeat that in ENGLISH, Miss.☝️
Incidentally, Slave, are you VEGAN? 🌱
David did well.. His ideas are interesting, BUT unfortunately, it could be argued that philosophy is a "spent" discipline with very LITTLE to add concerning modern theories and other scientific insights..
