Ignorance Definition and 34 Threads

I realize that it is impossible to know both the speed and position of a particle because of the uncertainty principle. I also know that this is because if you send a photon at the particle to detect its position you alter its momentum. But does that mean that when you measure position it has no...

Hi everyone. I am reading through these very interesting (in terms of topics) notes: https://arxiv.org/abs/1807.05996 And so far I am at Section 5. The author gives me the impression they don't seem to fear to call what is Bayesian and what is Frequentist, making the distinction in applications...

http://qr.ae/TUpoRU "Entropy is a measure of our ignorance about a system " Is that accurate ?

(To any passing moderator: Feel free to move this to "statistics" forum if you feel that would be more appropriate.) Although my "to read" list is already too long, I have lately been getting increasingly interested in learning the basics of conditional probability, including Bayesian analysis...

The purpose of this post is to describe what may be a useful way of viewing some aspects of QM. It probably doesn't rise to the point of a testable theory. Over a year ago I argued against the Many Worlds Interpretation based on quantum conservation of information. My argument was this: Any...

Hi Everyone, I am very ignorant and uneducated but I have a few questions about a difficult thought experiment. 'How does time flow in a video game/simulation or even in our imagination in relativistic terms?' Let's say a processor operating at 4.2 Ghz, 42 billion instructions per second at...

Ecell = E0cell - (RT/nF)lnQ So I understand the Nernst Equation, but I don't have some info. (Please bare with me, I'm in secondary) I'm doing a Cu - Al cell. My E cell is negative (-1.33). Does this have an affect on the equation? What exactly does E0 stand for? I understand how to find E...

ZapperZ submitted a new PF Insights post Imagination Without Knowledge Is Ignorance Waiting to Happen Continue reading the Original PF Insights Post.

I've read a lot about QM and studied the math and how it work many and many times in several lectures in several places, but whenever I review what the theory says and compare it to how the measurement work, I come to doubt in the theory it self, I think it can even be explained using classical...

I would like people's opinions on why the negative energy solutions of Dirac's Relativistic Wave equation were simply ignored in 1934 to make things fit. Another related question is with the energy conservation laws as they stand. Why in pair production from a photon at 1.022MeV forming a...

Lets suppose we have an object but we cannot tell anything about it.Energy,speed anything you can imagine.If there's no speed or energy,Is this means we can't tell object situation in physics Is that possible.Cause we have a object but we cannot describe the situation of it (I mean using...

what if there's a way to measure speed and direction at the same time and we haven't found it out yet? does it have to do with information theory?

I think I understand it but I prefer a response from a sci advisor rather than whatever someone put up on wikipedia. I also searched for it here but I didnt find a proper explanation. Any help would be greatly appreciated.

Please help me fight ignorance! I need someone help me develop a witty response to the following status I found on Facebook. ---"i wonder why wind we cannot see. or imagining we can't see wind. we sense that something is there and seeming to be moving. but what? made up labels of made up...

If you have played games of chance, you may have seen rolls of the dice, or flops of the cards that did not strike you as being random. I have played many games of backgammon, where the roll of the dice trumps talent. You can be bearing your checkers off, and lightning strikes. You get hit...

Attempting to read an advanced-quantum-theory and other hyper-super-califragamalistics suggests to me: not only is it fruitful to work quickly in physics, but also to assay, quickly, what you don't know, and what resources you need to fix that. In fact: I'd like to know your perspectives: how...

Hypothetically, say we have X, who's in a relationship with Y. Y is not sure that it's in love with X; which makes X insecure as X is. Or at least, that's what I always see around me. But think about it, wouldn't it be an advantage for X if Y wasn't? I mean, Y acts the way it acts towards Y any...

Now that I am fully immersed in my college education I have finally realized that the more I learn the less I seem I know. I always thought it was an old saying but nothing like hitting the "reality" wall to truly open your eyes. Presently, I find myself 4-5 hrs in a library hunched over a book...

I think it's my ignorance of not accepting that I can't do it, because I'm almost certain that it cannot be done, yet I'm still asking. Anyway, can this equation be solved for m? \frac{\pi}{n+1}=cos^{-1}\left(\frac{1-m}{\sqrt{1+m^2}}\right)+\frac{(m-1)\sqrt{2m}}{1+m^2} If it cannot be...

I've watched the Dateline NBC episode on Vincent Brothers, and was disturbed that the evidence used to convict him was exactly the kind that UFO crackpots like to use. Here's a pretty good summary of the show, even though it's from an unreliable-looking website...

i have a very simple question...what is the main assumption on which quantum physics is built on?... i guess every theory is built on an assumption...so is the assumption that the universe is a total kayos where uncertainty prevails?...please someone tell me?

The bullies at his Centerville high school were not "mentally ill." The gun shop owner who sold the pistols was not "mentally ill." The university officials whose judgment lapsed were not "mentally ill." The media trying to divert attention from poor reporting were not "mentally ill." The...

Would something straight out of The Giver, an equalized, perfect, emotionless society, be "wrong"?

Oh my god... i don't know what has been going on the last 2 weeks but I have gotten into conversations where no less then 30 people have shown that they either 1) Don't want to believe Special Relativity is correct or 2) Claim they know how SR works but in actuality have 0 understanding of it...

Can there be such a thing as a cone of Ignorance? Can somebody be so ignorant as to drag other people down to their level just by being in close proximity to them? And if this can be so, does that mean that a cone of depression can also exist? Are there any other cones that you can think of?

If we truly knew nothing -tabula rasa style - would we be happy?

I just heard the most ignorant comment made this week, i don't want to disclose the specifics of the person, because there are so many members here, that maybe they will know the person... I suppose you all know yoga, well I went to a local class just to see how Americans do it, being Indian...

Bush ignorance of his own "marriage" amendment When asked recently whether his proposed amendment to define marriage as a union between one man and one woman allowed for civil unions in general - which he had publicly supported - President Bush said he didn't know!

Conflict?...ignorance, greed or other What do you think is the #1 cause of conflict? I would say it's greed, with ignorance comming in second.
