Ok. Maybe I anounced my loyalty to early. I just read what I took to be a time limit, and that this python thing would expire in a month. Man, I thought I finally found a free one that will actually work.

Does anyone know of any links of any programing language that would come in handy and is free and without a time limit or do I have to go out and buy a compiler, interpreter software etc... myself?

What is an average cost and where would I buy one?

What is the language that is best used in things like programming robots? Since that is my obsession I would like to learn it.

Also, {I am kind of new to programming}, is visual where you set things up with pictures etc... and the program you type it in converts that into program language then that is decoded into machine language? Is visual more popular/easy versus the others?

Would I be able to say, given that I knew a programming language and had a compiler for that language, go into notepad and type a program and save it as an EXE. or whatever, would that be viable? would it compile it and be a program or would I need some other program to help me?

Thanks.

Just downloaded Python and starting to learn it, and since I did that, I might as well put my flag up:

hwazzagh!

Nanotechnology.

Quantum computers.

Long distance space flight {fuel, design, need for gravity or something that simulates it}

Space elevator.

bioengineering.

Artificial speech improvements.

Global warming solution.

Cleaner {Greener}...everything.

Better information storage systems.

Artificial intelligence.

Cellular biology/immunology.

Quantum Gravity theory.

Nueroscience.

Microbiology.

Genetics.

These are all just some of the things that would help if they were invented/modeled. I myself want to go further in Computer science and Robotics for Artificial Intelligence.

Good luck with becoming the new Einstein or Da Vinci. {really, I think that that is what everyone here wants to do and beleives that they are going to, including myself [but I am only 16 so maybe that is just my youth]}.

How do you know its not only neurological?

I see. I guess my understanding of the 7400 series is mixed up. thanks.

I have another.

I have come to understand {please tell me if its wrong} that for programming something, you input information into some form of memory, and the information has an address at the beginning of it, so this little reader thing goes through and reads the address and sends information to wherever it is supposed to go {wich is say, right after the address}. Is this similiar to how it works? It seems alot like DNA and the enzyme helicase to me.

If it is similiar, then my next question is, how does that specifically work?

So stored program computers and logic gates sets are totally different things, but can both do similiar things, and each have their own ups and downs, am I right? for logic gates 'computers' it is more designing than programming right?

Bascule, I read up on the von nueman architecture, and I also read up on the turing machine, what do you, since you seem to know a good 2 cents on computers, think is more simple to understand/superior?

thanks alot man

what decides what?

What is the cause of one wave function to collapse and the other not?

OK, another quetion, I was reading about a picture I found and it said that someone constructed a computer out of solely 7400 chips, and a hard drive pretty much {buses too, obviously}.

Thats impossible right?

what else would you need if it is?

merci beaucoup

long coiled resistor wire=heater.

I think that the double split experiment can help you understand this.

And it is not just us measuring it, it can be any interaction were information is exchanged. whether a photon bumps into the subject, or a molecule etc...

ignore sorry

Could you design one of these with two 2-digit inputs and a 3-digit output?

You could add an extra wire without a signal (0), as is, I beleive, {just learned yesterday} used in full adders.

So, this is the thread that is the one where I will ask all my questions regarding computers due to the fact that I seem to be taking up too many threads with all my questions.

Here is todays question;{oh, there is more to come if no one minds}

I was wondering, what is a computer program physically? is it just addresses for specific logic gates? When you type in a computer program, does it just have different logic gates for different commands, {and those logic gates have addresses}, that when typed in has some sort of address assigner that directs those signals to the logic gates wich do what is needed {math, etc...} and displays it on the moniter?

Thank you.

Ha, that is exactly what I visualized something to work as, but I would rather buy one at the moment just for better quality, but I guess I will make it myself thanks.

Alright, so I want a small, {inch or two}, sensor of some sort that, when bumbed, {just slightly}, sends out an electrical signal. What should I use and how much is it?

Thank you.

I see, thank you for all the help. You have proven quite helpfull. I do understand the TTL gate, and I prefer that one anyways.

Alright, I know I said last one last time, but I have acquired 2 more. {I have alot of questions, sorry}

1. I have been looking everywhere on the internet, but I just can not find it, what is a transducers symbol? Specifically an "S" load cell/load transducer?

2. How in the world do TTL logic gates do math? I saw on another website {http://www.mainbyte.com/ti99/electronics/gates.html} where it shows a picture of TTL gates doing "math", but all it does is convert a 1 0 signal to a 0 1 signal. ? is there some sort of decoder that changes the 01 etc... to the real binary numbers like 01, 10, 11, 100 etc...?

Thank you.

Thank you.

One more quick question, I dont fully understand how AND gates are made. I know that they are , but I dont really get the voltage at the top part. So, theres is two diodes, a resistor, and a positive {letting energy out of a battery}in the one I am talking about right? I am not talking about the one with transistors.

So, these two diodes, wouldnt they just stop all current from coming through? so the truth table would just be whatever A and B are, its going to 0 that comes out? I am not quite sure what the resistor and the voltages role is. And what is the base down there supposed to be?

Can anybody help me?

Thank you in advance.

Alright, quick Q:

What exactly do logic gates do in reading a program and executing it?

Thanks.

How is prolog? Has anyone tried that around here?

Cool. Thanks guys.

How do moniters take bits from a set amount of wires from the computer to every individual pixel? there can't possibly be a microscopic wire connected to every pixel can there? That would be unbelievable

The only thing that I can think of is that the pixels are like a matrix and the bits somehow {thats my problem, if anyone can explain, that would be cool} just "pass" the pixels at the bottom and get to the top.

Is there individual addresses sent along with the image bits as well? How?

Also, how can images be presented digitally with pixels? Is there 2 wires to represent the three colors in binary per pixel?

I know that I ask alot of questions here on these forums, sorry if it annoys anybody. Just curious.

Thank you.

die hard liberal.

why dont you post your hypothesis and well see where it goes.

I was thinking on how creativity could be implemented into a machine, wich led me to ponder, is creativity just a collective amount of past experiences that can relate to what is wanted to be created? Is there any experiments or discoveries similiar to this? what do you guys think?

Ok, thanks alot. So it is the 2nd.

Are integrated circuits just miniaturized versions of bigger machines? I know that I sound like a real simpleton but I am trying to ask very basic questions so I can understand the basics.

How does an integrated circuit work? I know that they are made out of semiconductor devices,and I understand what logic gates do, but I dont understand how any of these IC's work, its like black magic to me.

From what I have read, they are just transistors, and not only that, but the apollo guidance system was just like 4 transistors {ssi}, how do just 4 transistors guide a spaceshuttle?

Do these have addresses for where specific sets are? like heres the adders, and over theres the... they would have to right? it cant just be random wires and gates that bits go through and change.

aghhhh.

I am lost. If anyone can help me out, or give me a good tutorial or link or something, I would be gratefull.

Thank you.

So I am just trying to further understand how a computer works down to the core, and am mostly trying to come up with the stuff myself, and I have come to the conclusion that their are two ways a calculator and an alu works.

1. the device has the answers to problems already stored in its memory, and when you type a problem, its the same thing as typing in the address in a computer, but this would take a lot of memory, and everything just being bits, its very complex to me. maybe someone can elaborate on this if this is it.

2. the device actually does the problem itself, through logic gates or something, I dont know, maybe someone could help me on this if this is true.

Are computers just like complex mazes? I just cant wrap my brain around how something can read an instruction and do it. I know that sounds simple, but I try and try to draw ways onto paper myself {because usually, if I need something, my attitude is just invent what you need regardless of what is out there already, and if theres better stuff out there, still draw it all out, then go buy it, now that I would have a complete understanding of what it is and how it works}, but I cant seem to understand it.

Maybe if you start with what happens when you press a button, on say a calculator. bits like 01 are represented on two seperate wires right? how else could it be, how could a system register a zero?

If someone helps out here, that would be greatly appreciated.
