Also seeing that you are correct that this would be an engineering question rather than a physics one, would it be possible for this thread to be moved there so that no confusion comes of this in the future.

I posted in the physics because I was unsure of the section and was not thinking at the time to place it in the engineering section. I want to work on the electrical engineering model.

I am studying electrical engineering again and have read that the electrons travel from the negative lead to the positive one at a very slow velocity. Now the book states that in order for the mechanism for voltage to work an electron accumulation or "build up" occurs at the negative lead and when a non-zero resistance in placed between the positive and negative leads an impulse of energy is sent through the conductor which connects the positive and negative ends of the battery. My question is, as seen from the title, if that pulse happens continuously then how fast are the electrons building up or accumulating at the negative end of the battery. What would this depend on? My guess is that it must be happening pretty fast in order for a pulse to occur then there must be some difference. My guess is also that its not a continuous pulse but instead a discrete pulse because the electrons are being re-accepted back into the positive lead of the battery.

I...did not Ah..I see. I was being stupid and miss interpreted what your link meant. My mistake. I will take a look around.

ah, my mistake. Never knew about that cognitive bias.

When I stated "My current understanding for them" I am meaning that the working comprehension I have developed is based on knowledge which may not be true. In this I believe that I have distinguished a difference in meaning between "knowledge" and "understanding." What I mean by understanding is that I am trying to apply some given piece of knowledge which leads up to the quoted section above. The piece of knowledge that may be true or false. I do not see where I may have confused the terms "understanding" and "knowledge." If I have please point it out in the my wording and I will correct myself.

Thank you for your response @studiot however the link you provided does not necessarily define what rules are. Whereas it provides two sub links of "rule consequentialism" and the "rule of law." Now rule consequentialism talks about the usage of a rule in the formulation of a given ideology such as utilitarianism. It also initially talks about the use of rules in the deciding of a given morality. However its only mentions is in passing and is not defined. The "rule of law" speaks on distinguishing between "the rule of law" and "a rule of law" while also being applied to some given legal morality. However this type of rule I believe is applied in the scope of morality and not in scope understanding what knowledge is. Although I could be wrong. I am looking more to define what a rule is based not on morality but from a framework of understanding what knowledge is. Also while writing this I found something called, "Epistemic Rules." Not sure if this is what I am looking for. Will read on to see what it is about. Hopefully will not get distracted. I have also seen and learned about "if->then" statements. Is this a rule?

The purpose of this topic is for me to try and gain a better understanding of what "rules" are in the context of understanding of what knowledge is. The question that I wish to begin this topic on is "what are rules ?" in the context of philosophy? My current understanding of them is that they are repeated actions or behaviors of some observation. Say for example seeing a car multiple times in a row. You may define a rule stating that "a car will pass by." Thank you for your responses. edit: reduced it to remove all the vagueness

I have decided to go down the path of scientific computing for my CS major and I want to improve my knowledge on the subject. Does anyone know of any free resources available that I can maybe look into? Thank you for your responses.

So java code gets interpreted on the java virtual machine which then get translated to the computers processing instructions through the jvm? But why does java have so much portability? Is the JVM easier to write than a c compiler for the processor? How does that work? Sorry if I am skipping around in learning about computer science. Things are just brought up that I am completely blank on.

OOOOOHH, ok I think I understand now. You want to implement each object as its own separate thing which can be used and implemented in different areas with other classes/objects. All of which come together to form an overall software or program which gets executed in the main/driver class. And you want to maintain this separating principle because it allows for some kind of translatability between classes. Analogous to say not necessarily a function but a physical construction of something. Like building blocks kind of. Except they can be called and implemented differently. A guess I would have is that this would prevent massive code from falling apart. So if the program breaks then it is either one of two things. The object or the computer. THATS PRETTY FUCKIN COOL! Now I remember someone telling me that everything in java is an object, how do you get from c in which java is built, I am assuming, on top of to an object understanding. Is java just like an analogous "wrapper" which makes programming life easier for writing in c? Or is it like "passing on the torch" where everything was once written in binary and then assembly then c and then other languages? Thank you again for your responses.

Apologies for the confusion, I meant to say "Black Box" Algorithm implying that the algorithms workings is unknown to the programmer when implementing it. Again sorry bad at English. So what do you mean by data which is dimensional, do you mean like data with more than 1 field or are you referring to vectors in cs language?

I thought this place looked shinier.

cool, thank you for the response. The book is a good read so far, very straight forward. Do you have any books that you could recommend from you time starting off? Before I ask any more questions how do you structure your different classes in Java? by knowing this I can have some reference with how I am learning it in my own study at uni. Also with algorithms in Java I understand that they are instructions, however I am not really sure how they interact with data structures if that makes any sense. Like when implementing an algorithm is it taking data from data structures as an input and outputting the processing step of the algorithm when applicable? Also, if you can write an program as an algorithm then what is the difference between the two? (just looked back and I think you already answered this question, just wanted to added in case.) Ex: say you have a sorting algorithm an what to sort the entries of a linked list, do you apply the black box algorithm to the data structure or is it written into the data structure as a method of the data structure class? Also is this all just dependent on what you want the program to do and is just slightly arbitrary/optimal selection of black boxes in different places? p.s. apologies for poor grammer. English is my first language, I am just bad at it.

I am learning about java programs currently reading Data structure using java by duncan bell when he goes over the basic structure of a java program. In which being at the lowest level is the "record/payload", the next being "data structures" the next being "the application" and finally is the "driver"/"main class." My question is where do algorithms factor into this hierarchy? Would it fit in with data structures? Or would they be at the applications level due to them actually using the data structures. Thank you for your response.

This is both reassuring and disheartening. My biggest problem is that I enjoy how the black box works and want to learn more, but when I look under the hood I get into theory which is boring your right. Its like a never ending game of "ohh a piece of candy" grabs candy and realize it's a grandma mint.

I am having a hard time just understanding data types, let alone getting to the skill level of programming my own libraries. That sounds like a "once I get a complete handle" on it kind of thing.

That is my first time actually hearing about an FPU, ok cool! Learned something new. Ok, I think I got a understanding for it. Thanks for the assist @Sensei

Ok, so those types have no inherent meaning besides just being pixel values on the screen and it all boils down to binary and their operations then if I'm understanding you correctly. Also thank you for the intro explanation which brought it all the way up from the 1s and 0s.

In computer science how do you go from 1's and 0's to the different data types such as int, float, double, Boolean, etc? It is all just an upper level of abstraction? Is is a function at the lower functional hardware level of the computer? Does it somehow deal with the different flags in the hardware/software level boundary(do not know how else to put that)? Thank you for your responses.

there's Kahn academy, they walk you through problems step by step with videos and quizzes to test your understanding.

here ya go bud. Nice and done like. Read this before posting in Homework Help - Homework Help - Science Forums

ah, thank you for the correction.

how dense are those beads? It could just be that they are floating up due to them being less dense than the water. However I could also not be understanding the question being asked.

There is a site called "Library of Babel" which goes through every possible image or 30 word length text. I do not know what you are really saying, but if ya wanna find a place that randomly combines words in every possible way that may be a good place to start.
