To anyone that is wanting to learn quantum mechanics through the videos, heed the professor's warning. Learn the basics first. This is typically the last class an undergrad has to take to get his or her's B.S. in the physical sciences. Almost every university requires atleast a full year of physics and calculus along with coursework in Classical Mechanics and Multivariable calculus before one can even set foot in the classroom
@troper22 or "we" could simply open up a book (remember those?) and READ it etc. Rather than obfuscate throughout life absorbing nothing- excuses that education "isn't financially possible/feasible- reserved for the intellectually idolatrous or the societal/financially elite." Technology, inventiveness and FREE books have provided the capacity with which to gain infinite knowledge IF serious, industrious and analytically persistent enough to pursue with unbridled fervor. "Kahlidge" is obsolete.
@troper22 I would like to add that this also requires linear algebra and differential equations. No not just gaussian elimination of matrices; we're talking hardcore shit like linear functionals, gram-schmidt process, inner product spaces, eigen decompositions and much more.
Many schools have linear algebra and diff eqs in one course. Most of these courses do not teach you the advanced topics need for QM. Take them separately if you can. To put it bluntly, QM does not fuck around :)
To "find" that which is supposedly omnipresent, at the rate of just once in 2x10^16 events, and at 2-3 sigma at that, is wishful thinking, at best. But it is never going to be enough for particle physicists. When they fail this time (and fail they will -- mass is a concept without absolute definition, just as time and space-time are), their military sponsors will provide even more taxpayers' trillions...
I know that QM has been around for practically a century, but I'm wondering what specific papers support the notion of "running time backwards" as Dr. Suskind is discussing. Can particles be "reflected" back to the electron gun if they are not observed? This is not time moving backward, but it sounds like it could be interpreted as such. Does anyone know? Should I just wait and keep listening?
An interesting series of lectures. For a simple pictorial introduction to quantum mechanics you could also try the book “ Quantum Theory: A concise guide for beginners” available from Lulu.com

This is an invitation to see an artist theory on the physics of light and time!
This theory is based on two postulates
1. Is that the quantum wave particle function Ψ represents the forward passage of time ∆E ∆t ≥ h/2π itself
2. Is that Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π that is formed by the w- function is the same uncertainty we have with any future event that we can interact with turning the possible into the actual!
There are two dimensions to reality, the physical and the metaphysical, however, there is no outer social conscious worldview because there is merely too much going on all at the same time within any perpetual moment, which brings up any subjectivity within any and all memorialization of people places and things, for any individual and any and all social medium impressions within any and all subjectivity. Deep thoughts by Jack Handy
@DrFruedienslip Interesting stuff you're talking about. I'm in the process of reading a book called "Words of Wisdom," which explains philosophical quotes and ideas. I've been somewhat distraught over the idea that, when thinking about the nature of reality and metaphysics, how far should you take it? At some point shouldn't you just step back and enjoy the world for what it is (whatever it may be)? Maybe that doesn't make sense, but it has been bothering me. What are your thoughts?
@mleeson94 I think any world is lacking when it comes within providing any better guide, so its always good to compare ones thoughts with other philosophers because we sometimes question what we or anyone experiences, which is what philosophic exemplification can and should one day provide, rather than religious ideologies which place most emphasis within any worship or any and all idolizations within any measure in comparison, which attaches to any identity or any assumed charachter trait.
@mleeson94 However to answer any question, its best to let things simply take shape as any bits and pieces which make any sense likely do not need to be memorized, but applied to any sense within any and all conscious observations which can and will be pertinent within what anyone already knows about themselves, there is a book titled Construal being written as we speak all about any physics to consciousness, which no one has ever accomplished before which can be known as far over due
@Mrtheunnameable How does anyone actually "Know" what they think or attempt to support within any fruitional construal, there is a major difference between memorization and actually visually conceptualizing any true physical experience; we are missing any point within how and why quantum theory came to be within any context as to why reality comes into question what anyone truthfully knows about how anything. There is no worldview no motion picture to timelookingforwardthroughanyrearviewmirror.
So what was any quest within any and all attempts for any Einstien to question reality but within any definition within how Quantum Mechanics likely intent is to end any and all arguments within any and all ideological concepts of God, because we dont know where anything goes which can and does question any persons concepts of guided directions while being conditioned by any and all religious fanatacism, (well wishers) and they call smart persons and non believers heretics?
Any and all constructive thought means something' doesnt it? Like any preceptual operativeness, any cognitive connotation and or any objectivity, as in keeping any mind tuned up to whats going on inside as many things outside have been invented which demands any greater accountability within any refined instructional genre. Any context is extremely pertinent within any and all eurdition, knowing anything physical and metaphysical while attempting to define any part to physical reality'
Anything Quantum Mechanical should be about exemplifying any and all physical intelligence, the human mind and anything which has been invented, there has never been any definition within what we are doing to ourselves and this earth, its just too much to exemplify all at once because it should include anything which can or exist which has everything to do within defining any and all physical truths; This should be about preserving this planet not expanding what we are doing...
This video course is better than a live class for someone like me.I never really liked taking notes during lectures.Taking a physics course was always out of the question for me,very complex and abstract.Now I can learn physics at my own pace,I can replay any part I have difficulty understanding.I don't have to view any of these lectures,but want to just for the sake of learning.
@FRANK1FM I just read and like your comment...... this is the beauty of many types of self education , a lot of which is freely available to the public, resources of which YouTube is just a part. If you like... drop me a message and I will send a web link which clearly tell you what I am talking about. who knows you may find some surprises !! I wish you success in the never ending quest for knowledge.
An intelligent person will focus on how cleverly the subject has been passed. A well-informed person will focus on the quality and coherence of information. A head-and-tail sized brain guy will only be able to see if comments are nerdy or not.
Cont. So we have Quantum theory goes Chaos theory. How obsurd is that? Just think of the predictability involving one individual who is more intuned or in rythm with these frequencies. Lets say that frequency is Neutrino particles. In harmonization with this vibration to brainwave frequencies. Correlating in rythm & wavelength would very much allow for HIGH predictability. A potential solution to ESP phenomenon. Now we have these Agenda driven sciences that wish to shroud the potentiality
Think of this. If there was a point of peak energy, then how would this very moment be unpredictable? If you are on your game, then you have a less occurance of randomness in comparison to others who are not in peak energy. So where does this randomness play a role in scenarios involving predictability. Is it that they are atempting to limit a theoretical science that has already spun outside of its bounds?? Its beginning to contradict itself. Infact, Neutrino particles already have.
I am an artist and when I create a work of art it takes energy and is a process over a period of time ∆E ∆t ≥ h/2π. There is always uncertainty ∆×∆p×≥h/4π of how the art work will turn out in three dimensional (4π spherical) space the position of the lines and curves π on the canvas. Every movement I make will have to start at the quantum level and will have an uncertainty of momentum and position therefore is Heisenberg's Uncertainty Principle the same uncertainty we have with any future event?
@nickharvey7 Nope, quantum mechanics laws only effects objects on very small things such as particles, classical mechanics work on "our" scale of size, the bridge between quantum and classical mechanics is studied in statistical mechanics.
@BenTacos To be fair, it's affecting us right now. But the probability of the things occurring are really, really low. It all relates to the wave length of the wavefunction of the object in question, and the wavelength gets too long for larger objects, like us.
@nickharvey7 I am an artist to. I had posted 2 comments above that may give you some ideas of your own, on what is merely a theory. As wierd as it sounds i get future recordings in my sleep. I suspect these neutrino particles may be the very first mechanism to explain these playbacks. I find that this seminar attempts to dismantle what Quantum theory was originally designed to explain. I find that all is not predictable, but it is only elusive to us on a conscious level. Math Unconsciously.
Jezus... >_> I wish they gave THIS at high school. Seriously! The LAST chapter of our LAST book reveals a tiny, tiny, tiny, bit of Quantum Mechanics... :(
I am getting extremely sick of hearing the same stuff over, and over again at school, and then having to look surprised and baffled, just to make the poor teacher happy... :/
@BeylaKaythin Most people and especially teachers have missed the point within defining quantum mechanics' its all about definng reality which has everything to do with the future of humanity' so who or what decides reason and wht defines logic?
An interesting and modern delivery of an elusive subject. Those who are interested in this subject might enjoy the following somewhat pictorial book “Quantum Theory: A concise guide for beginners”
He stole the deity playing dice from Einstiens theory that God does not play dice with the universe' quantum mechanics has more to do with the development of the human mind which has been conditioned within religious ideology' I dont mean to be rude but what is the point to any ediucational merit but to enhance the quest to reasoning' which questions any sense to direction? What is any premise within political debate?
on an intrinsic level there are and have been cycles to despotism' despotism is a long and unaswered question' but anything which does exist can be explained predicated within any sense to context; literacy' literacy itself has everything to do with existentialism or the tranfers within the exploitations to economic expansion' economic expansion is a very complex subject'associated to the spurs within technology within a manner of dilution' which questions any plan or resolve within democracy
@TheTranceWhale I think the illustration given by the lecturer is a bit suspect at 1:14. There is no mention of the initial tradeoff in error in position and error in momentum (Heisenberg uncertainty h/2 ~ Delta p * Delta x) in the equations as written (he mentions it in the response to the question). So final position x_f should be something like x_f = x_i ± Delta x + (v ± h / (2 Delta x)) t which gives, V_measured = v ± h/(2 Delta x). Time doesn't affect the uncertainty in these measurements!
@brendanarnold you cant think of reality as mathmatical' its logical' one cannot know what one cannot see' the real question becomes what is any origin in defining reality other than human vanity attempting to define its direction? its a big question when one takes the time to consider whats really going on with the world and human dominion' people often misinterpret what Einstien was attempting to accomlish which has more to do with socialogical physics' but who am i but a self educated person
@DrFruedienslip the Key to any sense in literacy is within the context to any supposition' which does imply any sense to any explanation to any physical experience or to anything which is real' this has everything to do with defining the constitution within the makeup to any and all cause and effect' however there is no motion picture to time or reality because it is an assumed proposition which people attach too' its simply a reasonable proposition that there is no unilateral worldview
@DrFruedienslip but the fact remains that physically we are depleting our natural resources as population increases' which questions any and all sense to political debates often conditioned to hereditary traditions of belief' Its a real eye opener however' there are no laws to the universe there are only the principles of all nature' now we can only memorize what is within books' but does this actually build any decree within any sense to knowledge? What is knowl~`ledge? is there a point?
I can't hear the question in the video at around 45 mins in but based on the answer I think the question is something like "The slit apparatus has a momentum itself. By conservation of momentum, any momentum ('kick') transferred to the electron will be compensated by an equal and opposite momentum applied to the slits. So the slits themselves are a measurement instrument of sorts. How can an interference pattern be observed if the electron, in passing through the slits, is being measured?"
i dont mean to be critical but this is speratic conversation and the question is what is the point? Are we defining reality? What is uncertainty? Predictability" this all presumes a world view to reality' we are speaking of cause and effect' howevere there are two sides to reality' the physical and the metaphysical'
@SakeBottle People dont understand the actual intent to quantum mechanics' or quantum physics which is to defne reality' but there is no reality other than the physical and the metaphysical' this professor is confusing' what is he really talking about ?
@SakeBottle The best way to understand anything is to think about what you really know about yourself' and write everyday' learning how to express your experience is the best thing you can do to enhance your comprehension skills' context is very pertinent whle attempting to interpret someone elses writings which often dont make much sense' read other philosophers writing while finding your own style'
i know this may be a dumb question but im about 46 min into this ... And my understanding is that if you observe an experiment in any way like the photon example and reversing the laws of physic's it will not reverse the same way. Hypothetically speaking just setting up the experiment would already obscure the experiment in the first place wouldn't it? Sorry if thats a dumb question lol..
Ty very much sir! I saw your piece in M.Freemans' show 'Through the Wormhole' and it inspired me, as a Chemist to look into things and learn more about nature and our surrounding. Also the continuing education is awesome idea. I could never get into fancy Faculties but I deserve to learn more :)
P.S. Religion in it's basic methods and teaching is wonderful, giving people hope and some faith, just look at 10 commandments, it was Humans that corrupted and abused them all.
@LeontariF1 Of course! I know he didn´t involve any religion. I didn´t mean it at all. He is a genius! I was talking about people writing in this chat...
Indeed, that is a great book. The View from the Center of the Universe opens up the path to a new paradigm shift in cosmologically understanding the Universe.
im studying physics and i like watching lectures online :)
in the lectures where i need to be present, its focused very much on the mathematics, with experiments inbetween. Not much explanation or interpretation.
Lectures like this help me to understand, but its much easier to digest, i can watch these in the evening with a beer.
I always found quantum mechanics sorta creepy. especially the collapsing-wave-tree-falling-in-the-woods-half-dead-cat-in-a-box stuff...probably much less so to folks who understand it, but to a layman..*shudder*
Fun is not the primary motivation, some people do it to train their brain and keep it working and in addition learn some new things about reality, some people want to know more about reality and want to know about what goes on in modern physics, and as a by-product train their brain. In the ideal case its also fun. I dont think much of the audience is doing research, and most of these that do research other topics and want a broader view.
Question: At around 1:11 when he discusses measuring the momentum of the particle, what if the first measurement is done with a photon with a very long wavelength (at time t1), but the second measurement is done with a short wavelength photon (at time t2). That way we would know the position at time t2 and it's velocity as well. Is this a valid approach?
@whufc4vida this would not work. The precision at which you would know its location at t1 depends on the wavelength you use. Long wavelength means not very precise. Shorter wavelength means more energy, and more distortion. So if you use a REALLY intense flash of light at t2, the uncertainty introduced by t1 will screw it up. But the uncertainty principle says that you cannot measure precisely what goes on between t0 and t1 !!! And at t2, you will still see the uncertainty.
second response... By the way, your question is REALLY great and clearly, when answered, helps to understand it. But when actually studying physics, you would be required to calculate this in a special case or in a case that is undefined in a special way. As homework, in the exams. The question you are asking has a very, very clear answer, which can be rigurously calculated.
I just realized something! Maybe the two theories of General Relativity and Quantum Mechanics aren't contradictory after all! Simultaneity (i.e. paradoxes) in relativity has a strong correlation to Heisenberg's uncertainty principle!!! Give me my Nobel prize now. lol.
Thank you for this.... I am 25, live in Michigan... I have always been interested.. Cannot attend a class like this (pre-reqs, and cash).. But this makes it possible.. THANK YOU
Thank you for this video, thank you! This is what the internet is supposed to be - the free flow and sharing of this type of information for anyone for free. This is wonderful and grand.
@Jim1905 based on my observations of humanity through it's ages. Survival at all costs is written in our DNA as it is on all creations of this planet. It is only natural for humans to twist and alter our surroundings for our own benefit. Do you see the high Church officials living in rundown neighborhood in a shitty house??? i mean gosh, look where the Pope lives.
Hi everyone. I am going to major in physics in college. I don't start until august and wanted to get a little familiar with physics beforehand. Ive never taken a physics class, just the basic high school courses, what would you all suggest I study up on to prepare myself for this field?
Well, be really, really good at algebra. University will prepare you for a physics major, for math in general I'd be really good at Linear Algebra and Calculus (which isn't too challenging, except some proofs, but other then in class I wouldn't worry about that). All in all, be prepared to have little or no life, unless you want to take ten years pursing a degree lol.
Step 1. Smoke a large, but not too large joint and watch carl sagans cosmos. Thats mandatory ! the room should be darkly lid, but not so dark that you cant find your cola and chips - trust me. Cosmos is very long, so dont see all of it at once. Step 2. while you watch it keep a pen and paper near and draw things - birds and stuff - but also write down names and equations used in the show - look em up on wiki .. 3. buy cliff notes.
@Jim1905 Yes I know quite a bit about all of those. GR is Einstein's theory that answers the question what is gravity?, QM is a modern science to understand the properties of subatomic particles and how light behaves. You cannot know the precise position of a particle if you accurately know the velocity, and vice versa. And M-theory is the unification of GR and QM which requires 11 dimensions which inevitably leads to parallel universes when applying Quantum Mechanics to GR.
That constitutes quite a bit? I'm sorry, but M-Theory is a speculation based upon a speculation based upon ad infinitum. Do you know why you can't simultatenously know both momentum and position. Do you know the field equations to Einsteins general relativity and common solutions, Schwarzscild, Kerr, Kruskal, P-G, Israel-Poisson?
@Jim1905 I took a second look at quantum mechanics and realized that this actually opens a door to a transcendental being. The fact that you cannot know the precise position of a particle if you accurately know the velocity, and vice versa is a property within our universe. So if you were to step outside the universe you would be able to know both velocity and position of each particle very accurately. In other words QM can be the language of 'God'. Maybe I'll become catholic again.
I don't think the works of Shakespeare and Da Vinci can be credited to religion. I really don't. Shakespeare wrote a lot about history, and a lot about non-Christian mythology and legends But his works were not based on religion. Nor do I think Einstein was religious. Galileo probably wasn't either. He got screwed over by the religion.of his day.
er-Shakespeare helped write the King James Bible and he was deeply in love with Greco-Roman mythology, for sure, but at his heart he also was religious. Galileo was religious, he tried to interpret the bible to suit his theories on the world, which was a big problem for the church (they thought it would be dangerous and it is, that's how we ended up with young-earth creationist).
well religion really has nothing to do with science, but please don't ever take away religion from the arts! You may have a point with science, though I suspect religious convictions of one scientist or another really doesn't matter, but it is ludicrous to think that religion hasn't given us some of the most beautiful pieces of art from Michelangelo to Shakespear, to Milton and Dante, Da Vinci, etc.
I'm a chemist student and this course is a compulsory. But the lectures that were given here were about how to do a mathemethical acrobatics to the equations.
As a chemist I dont learn equation very well if i dont have a reference point to the initial consept. I need the whereabouts of the math.
He is explaining well where the different equations come from and why they look like they do. This is the way i learn things. I would like to see this kind of lectures more :)
Maybe this is dumb, and I'm new to all this, but all this talk about looking at it going forward, then looking at it going backwards, brings to my mind if I watched on film or video in slow motion an object I had thrown which bounced, in reverse, then watched it not in reverse, they just seem different, even speed, but it's still the same, or listening to someone talk backwards, very different sounds then that same talking forward. Just came to my mind. And I doubt relates.
yes it really comfortable to understand and hope for more such videos of chemistry also....

Anything Quantum Mechanical should be about exemplifying any and all physical intelligence, the human mind and anything which has been invented, there has never been any definition within what we are doing to ourselves and this earth, its just too much to exemplify all at once because it should include anything which can or exist which has everything to do within defining any and all physical truths; This should be about preserving this planet not expanding what we are doing...

Cont. So we have Quantum theory goes Chaos theory. How obsurd is that? Just think of the predictability involving one individual who is more intuned or in rythm with these frequencies. Lets say that frequency is Neutrino particles. In harmonization with this vibration to brainwave frequencies. Correlating in rythm & wavelength would very much allow for HIGH predictability. A potential solution to ESP phenomenon. Now we have these Agenda driven sciences that wish to shroud the potentiality

Think of this. If there was a point of peak energy, then how would this very moment be unpredictable? If you are on your game, then you have a less occurance of randomness in comparison to others who are not in peak energy. So where does this randomness play a role in scenarios involving predictability. Is it that they are atempting to limit a theoretical science that has already spun outside of its bounds?? Its beginning to contradict itself. Infact, Neutrino particles already have.
LendMeYourHand 3 months ago
I am an artist and when I create a work of art it takes energy and is a process over a period of time ∆E ∆t ≥ h/2π. There is always uncertainty ∆×∆p×≥h/4π of how the art work will turn out in three dimensional (4π spherical) space the position of the lines and curves π on the canvas. Every movement I make will have to start at the quantum level and will have an uncertainty of momentum and position therefore is Heisenberg's Uncertainty Principle the same uncertainty we have with any future event?

@nickharvey7 Nope, quantum mechanics laws only effects objects on very small things such as particles, classical mechanics work on "our" scale of size, the bridge between quantum and classical mechanics is studied in statistical mechanics.
BenTacos 3 months ago
@BenTacos To be fair, it's affecting us right now. But the probability of the things occurring are really, really low. It all relates to the wave length of the wavefunction of the object in question, and the wavelength gets too long for larger objects, like us.

@nickharvey7 I am an artist to. I had posted 2 comments above that may give you some ideas of your own, on what is merely a theory. As wierd as it sounds i get future recordings in my sleep. I suspect these neutrino particles may be the very first mechanism to explain these playbacks. I find that this seminar attempts to dismantle what Quantum theory was originally designed to explain. I find that all is not predictable, but it is only elusive to us on a conscious level. Math Unconsciously.

@TheTranceWhale I think the illustration given by the lecturer is a bit suspect at 1:14. There is no mention of the initial tradeoff in error in position and error in momentum (Heisenberg uncertainty h/2 ~ Delta p * Delta x) in the equations as written (he mentions it in the response to the question). So final position x_f should be something like x_f = x_i ± Delta x + (v ± h / (2 Delta x)) t which gives, V_measured = v ± h/(2 Delta x). Time doesn't affect the uncertainty in these measurements!
brendanarnold 4 months ago
@brendanarnold you cant think of reality as mathmatical' its logical' one cannot know what one cannot see' the real question becomes what is any origin in defining reality other than human vanity attempting to define its direction? its a big question when one takes the time to consider whats really going on with the world and human dominion' people often misinterpret what Einstien was attempting to accomlish which has more to do with socialogical physics' but who am i but a self educated person

@DrFruedienslip the Key to any sense in literacy is within the context to any supposition' which does imply any sense to any explanation to any physical experience or to anything which is real' this has everything to do with defining the constitution within the makeup to any and all cause and effect' however there is no motion picture to time or reality because it is an assumed proposition which people attach too' its simply a reasonable proposition that there is no unilateral worldview

@DrFruedienslip but the fact remains that physically we are depleting our natural resources as population increases' which questions any and all sense to political debates often conditioned to hereditary traditions of belief' Its a real eye opener however' there are no laws to the universe there are only the principles of all nature' now we can only memorize what is within books' but does this actually build any decree within any sense to knowledge? What is knowl~`ledge? is there a point?
DrFruedienslip 4 months ago
I can't hear the question in the video at around 45 mins in but based on the answer I think the question is something like "The slit apparatus has a momentum itself. By conservation of momentum, any momentum ('kick') transferred to the electron will be compensated by an equal and opposite momentum applied to the slits. So the slits themselves are a measurement instrument of sorts. How can an interference pattern be observed if the electron, in passing through the slits, is being measured?"
brendanarnold 4 months ago
i dont mean to be critical but this is speratic conversation and the question is what is the point? Are we defining reality? What is uncertainty? Predictability" this all presumes a world view to reality' we are speaking of cause and effect' howevere there are two sides to reality' the physical and the metaphysical'
DrFruedienslip 4 months ago
To the question raised at 1:14:14 (if I heard it correct)
P(i) = Initial position = x ± ƛ.
P(f) = Final position = x' ± ƛ. (say)
v = [P(f) - P(i)]/t = (x' - x)/t ± 2ƛ/t.
Which only implies that the velocity ends up with double the uncertainty.
Where am I wrong?

@njin72
Fun is not the primary motivation, some people do it to train their brain and keep it working and in addition learn some new things about reality, some people want to know more about reality and want to know about what goes on in modern physics, and as a by-product train their brain. In the ideal case its also fun. I dont think much of the audience is doing research, and most of these that do research other topics and want a broader view.
anyway, this makes people smarter.
kurtilein3 6 months ago
Question: At around 1:11 when he discusses measuring the momentum of the particle, what if the first measurement is done with a photon with a very long wavelength (at time t1), but the second measurement is done with a short wavelength photon (at time t2). That way we would know the position at time t2 and it's velocity as well. Is this a valid approach?
whufc4vida 7 months ago in playlist Course | Modern Physics: Quantum Mechanics
@whufc4vida this would not work. The precision at which you would know its location at t1 depends on the wavelength you use. Long wavelength means not very precise. Shorter wavelength means more energy, and more distortion. So if you use a REALLY intense flash of light at t2, the uncertainty introduced by t1 will screw it up. But the uncertainty principle says that you cannot measure precisely what goes on between t0 and t1 !!! And at t2, you will still see the uncertainty.
kurtilein3 6 months ago
@whufc4vida
second response... By the way, your question is REALLY great and clearly, when answered, helps to understand it. But when actually studying physics, you would be required to calculate this in a special case or in a case that is undefined in a special way. As homework, in the exams. The question you are asking has a very, very clear answer, which can be rigurously calculated.

I just realized something! Maybe the two theories of General Relativity and Quantum Mechanics aren't contradictory after all! Simultaneity (i.e. paradoxes) in relativity has a strong correlation to Heisenberg's uncertainty principle!!! Give me my Nobel prize now. lol.

@FallofDarkness55
Do you know anything about M-Theory? Or what about GR or QM?
Jim1905 8 months ago
@Jim1905 Yes I know quite a bit about all of those. GR is Einstein's theory that answers the question what is gravity?, QM is a modern science to understand the properties of subatomic particles and how light behaves. You cannot know the precise position of a particle if you accurately know the velocity, and vice versa. And M-theory is the unification of GR and QM which requires 11 dimensions which inevitably leads to parallel universes when applying Quantum Mechanics to GR.
FallofDarkness55 8 months ago
@FallofDarkness55
That constitutes quite a bit? I'm sorry, but M-Theory is a speculation based upon a speculation based upon ad infinitum. Do you know why you can't simultatenously know both momentum and position. Do you know the field equations to Einsteins general relativity and common solutions, Schwarzscild, Kerr, Kruskal, P-G, Israel-Poisson?
Jim1905 8 months ago
@Jim1905 I took a second look at quantum mechanics and realized that this actually opens a door to a transcendental being. The fact that you cannot know the precise position of a particle if you accurately know the velocity, and vice versa is a property within our universe. So if you were to step outside the universe you would be able to know both velocity and position of each particle very accurately. In other words QM can be the language of 'God'. Maybe I'll become catholic again.
