Knowledge Definition and 383 Threads

When people speak about getting an education, I think of science, maths, logic as the key foundations to an education. However there are many who supposeddly have an education but may not have done any science beyond year 10 and are very ignorant about maths. Should these people be labeled as...

Good morning all, Anyone who is a physicist please respond to the following question: How would one go about gaining the knowledge of someone who has doctorate in physics without actually going to college (I'll explain why in a bit). My question is mainly targeted at what subjects I need...

Hi Everyone I have a object oriented C++ assignment which is due this week and I have no idea as to how start it.... This program prints a motion verb ( fly, run, swim, crawl, walk, or roll ), waits for a second, then prints the name of an entity and repeats the verb (for example: fly ..1s...

Lately, i have try to find a answer for this question. I will be glad if some of you would point me to the right literature. With that being said, i will tell you why i ask this question. I have attended numerious courses in mathematics, and physics, and the one thing i have noticed is that...

well as the title suggests, perhaps next summer ill be taking courses from our computer science department, i want to know how much knowledge of programming does a mathematician needs? up till now I am taking one course which is entitled computers for physicists. it's not much of a...

I'm having a bit of trouble distinguishing between procedural knowledge and propositional knowledge. Particularly in problem solving. Generally the difference between them is knowing how and knowing what, respectively. Propositional knowledge is composed of four parts, syntactic (learning...

General knowledge for you, but I NEED ANSWERS! I've always hated anything related to politics/economy/buisness. I hate business so much that I always spell it wrong too. I keep on putting the i before the s. Anyway, here are a few 'general knowledge' questions, which might be general knowledge...

Okay i am not a physics master. I'm in honors high school physics with a C. But physics is just so interesting. I just wish I was better at it. I'm always making stupid mistakes on tests Anyways. I am really interested in learning about the weird things in physics. Like tachyons, string...

Sometimes when we obtain knowledge from only one source, we become ignorant. Ex. Hardcore religious Fundamentalist. And when we learn knowledge by memorizing instead of understanding, it only gives us materialistic profit but no mental benefit.(getting an A+ in class) But how do we know we...

Problem Solving Skill vs. Mathematical Knowledge Here goes more of my mathematical musings: Problem Solving Skill vs. Mathematical Knowledge. Which is more important to you? Spending time to improve one will cost you time to improve the other. You must excel at both to become a...

hi everyone I am a new member to this forum and i study physics.. i would like to know if you know any sites with free e-books about physics :confused: thanks a lot

This is a question where the answer is given but I don't understand how to derive it. The answer to the homogeneous eq. is: A cosh(x) + B sinh(x) with no explanation of how it is arrived at and the given answer then goes on to describe how the non-homogeneous part is solved. Diff. eq. ...

Note: At the bottom of this post is a scan of the problem from the textbook, and then in the next post are scans of previous pages from the textbook, but (unless you're familiar with game theory) you probably should read my own words before you read the textbook scans. I have an equation: u1 =...

i tried searching for it on google but couldn't get the right term. Do you guys know of any research going on trying to transfer knowledge directly into brain like chip?

A tech fest is fast approaching in my university, and as part of the run up, a couple of my friends made a nice trivia quiz, which concluded yesterday. So, here it is. Feel free to google and remember to hide your answers using [ color=#black] 1. Identify the person in the picture. (Hint: He...

I'm working on a pricing request for an independant telephone company and they furnished me a list of countries for which they want pricing. What's the first country listed? Africa. :bugeye: I don't know how to bring up the fact that Africa is not a country without embarrassing them and...

Hi, as usual in September I am deciding which courses to take. I am in the second year of my study and so far I am following the more theoretical path, later maybe with focus on quantum mechanics and quantum information processing. My question is: which math courses should I take this year...

Hi, I am currently taken Pre Cal and it seems to be really easy to me (I have a 101 average right now =0 ) and I was wondering what is the highest math that you need to become an engineer that like makes highways, bridges, buildings, and stuff like that. Also, is Calculas AB and BC just as...

i read a lot recently about mysticism as means to knowledge. What knowledge specifically can it bring? Can ppl accept this "knowledge" even when its for them not reachable/verifiable, either due to the fact that majority of ppl don’t meditate, or because they cannot reach that level in...

Intelligence is the mental capacity to reason, plan, solve problems, think abstractly, comprehend ideas and language, and learn. I had a little thought experiment the other day, and I thought I'd share it here. If we define knowledge as knowing something, as in, a piece of information, no...

I'm trying to create a model for a car turning to make a differential (I need forces aplied on the wheel, and all other things) but I don't have enough knowledge of dynamics to do that. Does someone know a book(s), papers or sites with good explanation about that?

Near the top of this web page, there is a link to a quiz. If you take the Novice quiz called "Beginning Physics", you will find an error in question 4: Question: A cyclist changes velocity from 5 m/sec [N] to 15 m/sec [N] in 4.0 sec. What is the value of her acceleration? a) 2.5 m/sec b)...

According to the concept of space-time, we live in a 4 dimensional universe. But according to electro-magnetism and any other subject that uses imaginary or complex numbers, we express the world in 5 or more dimensions and assume they are imaginary, possibly because we have already seen they...

How useful is the knowledge of discrete math for computer programmers?

Sir: I need the knowledge of the quantum well, who can help me?

One of my goals in participating in this forum, is to get my physics chops back, after a long period in the hinterlands of commerce. I've learned a great deal from many bright and interesting people here. My introduction to QM happened almost 50 years ago, at which point I became fascinated...

sorry if this sounds a tad retarded but astronomical topics arent my forte...how do know if something is red-shifted without prior knowledge? say you've got light emitted from galaxy far far away at 500nm, and it ends up on Earth at 510nm. how can you differentiate between 510nm actual...

Hi, I would like to know your thoughts about the following two fact in physics; 1) Physics is scale-dependent; at each scale of distences we have different degrees of freedom and different dynamics, we need a different theory. 2) Physics at a larger scale decoples from the physics at...

Hi everybody, I would like to know: 1)what is the so-called VIRIAL in physics, 2) what is the VIRIAL THEOREM and 3) comments on its importance in physics. It always sounded too much mysterious to me. Thank you all, DaTario

Is it possible to know everything? If it is possible, then is it dependent on time? that is, for a defined moment in time (say a second), one person can know all that there is to know about the universe. since the universe is constantly changing, the future state cannot be stated definitely...

Is it completely impossible, even in principle, that eventually there can be a device by which we could know about the superposition of states without collapsing it? For example, being able to know that an atom is in a 30% probability of being unexcited and a 70% probability of being excited...

I meet a problem about "ion sputtering "in my work,I want to acquire some knowledge about "ion sputtering ",who can tell me where can i find relative articles? THANKS!
