What is Ignorance: Definition and 34 Discussions

Ignorance is a lack of knowledge and information. The word "ignorant" is an adjective that describes a person in the state of being unaware, or even cognitive dissonance and other cognitive relation, and can describe individuals who are unaware of important information or facts. Ignorance can appear in three different types: factual ignorance (absence of knowledge of some fact), object ignorance (unacquaintance with some object), and technical ignorance (absence of knowledge of how to do something).

    I Uncertainty = our ignorance or intrinsic to reality?

    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...

    A Bayesian Priors and relation with ignorance

    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...

    Has anyone read "Willful Ignorance" by Herbert Weisberg?

    (To any passing moderator: Feel free to move this to "statistics" forum if you feel that would be more appropriate.)

    I QM Ignorance is Bliss: Exploring the Limits of MWI

    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...

    How do we simulate time flow in video games? EE/PHYS

    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...

    Is Quantum Mechanics an artifact of our ignorance?

    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...

    Can You Determine the Randomness in Backgammon?

    Quickly assaying ignorance in the heat of research

    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...

    Is Love Just a Chemical Reaction or Something More?

    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...
