YES! That was what I was trying to ask! Sorry if I wasn't able to elucidate but the Otrhodontist got my idea. If the pit was a canvas, then what is IN or ON the canvas? On a painting, it's paint - and that's what makes the painting - but on a DVD? So it's a series of pits AND land - not just the...

Thanks everyone. Orthodontist and Jobs' posts were very comprehensive, though I had to read them twice before I started to get it. I like the analogy of the paintings. I understand the 1s and 0s and the "pits" being the places where the data is stored. So would I be correct to assume...

Hi all As I was burning some files onto a DVD, I asked myself.. what exactly is "IT" that I am burning onto this thin disc. And then I kinda got freaked out.. hehe. Cause what the heck is data anyways? It's this... thing that you can't see but when put into the right hardware, can play...

It is 50hz down here. I still haven't plugged in my player yet lol. Maybe my player will just be for show now hehe. Model player. Just kidding, I'm off to buy that voltmeter. Thanks again guys.

thanks averagesupernova and hammie. Well Hammie, the thing is I don't have a AC voltmeter. If they aren't too expensive (like under 10 dollars from the hardware store), I might get one. So If the voltmeter says 110-130, then it should be ok right? Well I might check that alternative...

Hi folks I found a STEP DOWN transformer lying somewhere in the basement from way back when and I am not sure whether this thing is going to do what I think it does. I am in Australia, a 220-240V country. I have a US DVD player and it's 110-120V AC. It says on my transformer... INPUT...

Hi After many years of bad habit, I now have trouble regulating my sleep times. I would find that every night I would sleep a quarter of an hour or so later, and wake up later too. Eventually, I would end up sleeping in the mornings and waking up around sunset, only to have the system turn...

Hi everyone I've lived in "hot" and "cold" countries and the a/c systems installed in the homes are desgined to either "cool down" or "warm up" the house. So take the heater for instance. There is a 10 degree mark on the dial. Now 10 degrees is pretty cold. So what is stopping me from turning...

Thanks Arildno and Ashmanovski. Ash, that is a really lucid explanation. I get it now.

Hello. Chromosomes and Proteins are 2 things I can't seem to understand. 1. Chromosome - So is the chromosome, DNA or not!? Where are these chromosomes located? When DNA is mentioned, it's usually a twisting ladder with rungs. The rungs and the sides of the ladder are made with nucleotides...

Hi everyone Thanks for dropping in your opinons. To Mr. J: Thx. I'll check those books out eventually. Think I have heard of "Selfish Gene" before. To Serpo: After submitting the thread, I realized it did come off as a little sordid. It would have been more appropraite to use...

What is the philosophy behind "being accepted"? Anyone know any books written about this topic? That most people devote their lives into trying to make themselves likeable. Or even worse, just try to "make" people like them. Personally, everytime a partner gives consent to start a...

Hi JT Thanks I got it now.

Hello This is a section from a textbook... "an ampere is defined as that current in each of 2 infinitely long parallel wires 1 m apart that causes an electromagnetic force of 2 x 10^-7 per meter of its length to act on each wire" Hmmm... was that in English :smile: ? q1...

It is HallsofIvy's FIRST OPTION. I am sorry for all the confusion. I finally got it. The step I forgot to do all along was SUBSTITUTE the sinx part INTO the derivative of the OUTER FUNCTION (Using the chain rule). I was sitting there with the derivative of the outer function (3/3*x^2) and...
