But I don't think that, for example Athlon 64 3000 is two times faster than Athlon XP 3000 which has 32-bit architecture. Also the cost is almost the same

In this picture I get to input A and B value and process it? If so, how do I recognize if it's AND or NAND gate? Those look the same

Do you know from what stage (grade 12 subjects, first/second semester of college?) it gets hard to learn things?Iheard that Physics/Math 12 are not that hard but in university, it becimes much harder right away.

I've got a question - can anyone tell me what is the difference between 8, 16,32 and 64-bit buses?

I am afraid I haven't But, OK, I am going to find some information about that

So, even now there are reactions happen in stars that create new elements? (what type of reactions?)

If you know something about chemistry - why are there so many elements in the World? (why isn't there just one element? (in periodic table))

OK, but how have all the galaxies, stars, quasars, black holes, etc, appeared?

And what made that singular point expand and convert to molecules?

Can someone explain to me how CPUs work? I know that the "information"(bits/bites) goes between memory (HDD or RAM) and the CPU which processes that information but how does it do that? How do we get solved equations and formulas instead of just numbers?

Is this offered in Canada?

I thought singularity is a very little (infinitly) point which is, therefore, much more little than an ordinary atom

But how come our Universe actually exist? There was no "time" before the Universe appeared because the "time" is just one of the aspects it.

I have one more question - why is the Universe so harmonic? I mean why isn't it just a bunch of molecules located in regular intervals without any аttributes of life? That singular point must have had perfectly definite "push" to have, in result, our universe even with possible existing of life

yeah. Thank you all for support. I really shall stick to this forum

You read my mind

Will I have enough spare time? What is the "everyday schedule" of studying in college. I mean how much time do I spend in college everyday? Thank you I am and I will If you study physics - when will I start studying Theory of relativity, Quantum Theory and other hard subjects?

You mean - if there was no "time" then nothing could be "brought into being"?

I don't exactly understand what you're saying...

I've seen a movie where a guy was cleaning washrooms and floors in college because he couldn't find a good job after the college nor give back the money he loaned. Can it be true in real?

I am in grade 10 now. And I am very interested in science (physics, astronomy, chemistry) But when I see some threads/topics on physics and other science (even grade 12 physics) I just can't believe that I will ever be able to understand or remember whole bunch of formulas (but I hope I will become smarter when I grow up )! Besides I don't know any good ways to earn like 75000-100000$ for my education. There is one more problem - I immirgated from Russia only a year ago and It seems hard to speak english perfectly by the end of high-school.

Here is the question - How/why/when has Universe appeared? The only thing i can think about is that It has appeared from The Nothing You will say that was all about the singularity but from what, then, the singularity appeared? If our Universe appeared from nothing (and without a purpose/reason), then I can say that there are infinite number of "Universes" (in our perspective) appear every "moment" with totally different laws of nature, logic, constants etc which we are never gonna understand, because we weren't born there and having different brain. Very probably that all the universes aren't interconnected so technically we can say they all don't exist (in our perspective) therefore we don't exist for some other civilization in another "universe". What do you think about it? PS Sorry for my english - I am only 1.5 years in Canada

For example I graduate high school with average of 50-60 % in physics, mathematics etc. (or don't finish at all). Would I be able to apply for university? Also, are there any tests or quizzes before you go to Univ?

I meant requirements to get science courses. What about the scholarship money? How do I get them? Are public universities much worse than private ones?

So, you're saying that education is much cheaper if you are a citizen? (or resident?) I really don't understand where young people get such a bunch of money to pay for education. Do you know any good opportunities to get the money for that? Also I heard about some "student loan". Can you tell me about it more? What about the requirements?
